US Issues Patent 7,500,000

The USPTO issued patent no. 7,500,000 on March 3, marking a new milestone in US patent documents. The subject of the patent is a "Method or System for Assigning or Creating a Resource" in a computer storage device, such as a hard disk drive, non-volatile RAM, or optic disc. The patent was issued to four inventors, led by David W. Groves, and assigned to IBM.

Patent no. 7,000,000 was issued three years ago on Feb. 14, 2006 to John P. O'Brien of Dupont for a new type of polysaccharide fibers and their production.

USPTO Publishes 2,000,000th Application

On February 5, the USPTO reached an important patent document milestone: the two millionth published application. The first US application (2001/0000001) was published almost eight years ago on March 15, 2001. The USPTO published 6,581 applications on Feb. 5. Depending on how you count (including or not including withdrawn published applications), the two millionth published application could be 2009/0035278, Reoviruses Having Modified Sequences, or 2009/0033321, Rotational Angle Detection Device.

The inventor listed on the first application is Matthew Coffey of Calgary, Alberta. The assignee is Oncolytics Biotech, Inc., also located in Calgary. Reoviruses are used to treat disorders where cells proliferate more rapidly than normal tissue growth, ie. cancerous tumors, in mammals. The inventor on the second application is Takeo Kurihara of Tokyo; the assignee is Tokyo-based Tomen Electronics Corporation. Kurihara's invention is related to devices used in magnetic sensors. Tomen has filed PCT and national applications on this technology in the US, Japan, China and Europe.

As of March 1, 2009, according to the USPTO website, the AppFT database now contains records for 2,021,756 published utility and plant patent applications.

Wikipedia References Increase

The Jan. 29 of CNET's Buzz Report has a funny rant about Apple's recently issued patent on a multi-touch graphical user interface. (US 7479949) Complaining about the USPTO's examination practices, reporter Molly Wood cites examples of existing prior art on multi-touch technology. Her funniest line is "This is on Wikipedia... you could look this up!"

Back in September 2006, the USPTO ordered examiners to stop using Wikipedia as a source of information for determining the patentability of inventions. However, examiners and applicants continue to cite it. The number of patents issued in 2008 that cited Wikipedia articles nearly doubled to 508.

Titles Added to Cited References in FPO

US patent records in FreePatentsOnline now display titles of cited US patent documents. This is a nice improvement since it provides more information about the reference without forcing you to leave the current document. Titles of cited references available in the USPTO database nor are included on patent documents.

However, I noticed recently that some FPO records do not include all the older cited references. For example, US 3,803,463 cites 8 US patent documents, the earliest being 8,843 issued in 1852 and 644,896 from 1900. However, the FPO record for this patent displays only 6 cited patents, the earliest being 2,401,815 from 1946.

After further testing it appears that the problem is limited to pre-1976 patents.

Inventor of TASER stun gun dies at age 88

Jack (John) Cover, inventor of the TASER stun gun used by thousands of police departments worldwide, has died at the age of 88. According to his obituary in the Washington Post, Cover, a former NASA scientist, invented the nonlethal device in the late 1960s in response to hijackings and riots. He applied for a patent for a "weapon for immbolization and capture" in 1970, filed a continuation on July 10, 1972 and and was finally granted a patent (US 3803463) on April 9, 1974.

Cover's 1974 patent has been cited by 43 patents including an "Electronic Disabling Device Having an Adjustable Output Pulse Power" issued on January 6, 2009 to Corey Rutz and Michael Kramer and assigned to the Defense Technology Corp. of America in Casper WY. (US 7474518)



The electric gun has been a long-time fixture in sci-fi and adventure stories. In fact, the name TASER was inspired by Cover's favorite character from a novel called Tom Swift and his Electric Rifle (TSER). The A was added later to make the name easier to pronounce. Inventors have been fascinated by electric weapons for more than 100 years. In his 1974 patent, Cover cited an electric harpoon patented by Dr. Albert Sounenburg and Phillipp Rechten in 1852. (US 8843). This is another great example of the importance of including older prior art in patent searches.

TASER International is based in Scottsdale, AZ and holds 25 US patents and dozens more worldwide.

Top Inventor Receives 577 US Patents in 2008

The other rather surprising statistic in the Boliven Patents Top 25 Report for 2008 was number of patents secured by the top-ranked inventor, Kia Silverbrook, founder of Silverbrook Research, a private R&D firm based in Sydney, Australia that specializes in inkjet printer technology. According to the report, and confirmed by checking the USPTO website, Silverbook received 577 US patents in 2008 (581 according to the USPTO). That's almost two patents a day. This is amazing. Thomas Edison received only 1,093 patents in his 60-year career. As of Feb. 12, Silverbrook is credited as an inventor on 2,430 US patents and 3,435 published applications. According to Silverbrook Research's website, the firm has more than 1,800 patents and 2,000 pending applications and employs over 400 research scientists, engineers and support staff.

Chinese University Ranks 10 in US Patents

This week Boliven Patents released its first Top 25 Report for 2008.

Some rather unexpected statistics caught my attention. The first was in the university assignees category. Not surprisingly, US schools dominated the list. The top five included the Univ. of California (252), MIT (228), Stanford (137), Caltech (115), and Wisconsin (99). But just breaking into the top ten was Tsinghua University (60), one of China's leading universities. According to the school's website, Tsinghua has 44 research institutes, 9 engineering research centres and 163 laboratories, including 15 national laboratories. And #24 was the Korea Advanced Institute of Science and Technology. This seems to confirm a trend noted by the WIPO and other organizations: patent activity in Asia is increasing rapidly. It's nice to see American universities getting some competition.

(The USPTO also produces a statistical report on academic patenting, but it only includes U.S. colleges and universities and was last updated in 2006.)

Canadian Patents Database - Representative Drawings

The CIPO's Canadian Patents Database now displays representative drawings in patent records. This is a great improvement as it allows searchers to immediately see drawings as they scan search results instead of requiring them to open up the drawing image file for each record. It appears that representative drawings are only available for issued patents and laid-open applications from about 1990 forward.

New USPC Classification Orders: #1881-1884

The USPTO's patent classification office has been busy the past few weeks. Four new classification orders (#s 1881, 1882, 1883, 1884) have been published since January 1, not including the one that I mentioned the other day that established Class 850 (#1885). The new orders outline changes to:

• Class 359 - Optical Systems and Elements
• Class 361 - Electricity: Electrical Systems and Devices
• Class 362 - Illumination
• Class 180 - Motor Vehicles

New USPC Class: 850 - Scanning Probe Techniques or Apparatus

The USPTO has created a new USPC class for inventions related to devices that scan or probe at the nano-scale. The full title is Class 850, Scanning-probe techniques and apparatus; applications of scanning probe techniques, e.g. scanning probe microscopy (SPM). The class was established under Classification Order 1885, released on Feb. 3. At this time, Class 850 consists of 63 subclasses, 1-63. No patents or published applications in the USPTO web-based database have been assigned to Class 850. This is not unusual as the classification data is updated bimonthly.

Consolidated Glossary of USPC Terms

A new Consolidated Glossary of U.S. Patent Classification Terms is now available on the USPTO patent classification website. The glossary consists of a comprehensive list of terms taken from the classification definitions of the USPC. Terms are listed in alphabetical order and grouped by class number for easy browsing. These definitions are useful to patent searchers in that many terms found in the USPC manual have technology-specific definitions that are different from standard dictionary definitions.

New Patent Databse from Boliven

Boliven, a New York-based company, has launched a free patent database called Boliven Patents Beta.

The database contains data and images for US patents from 1976 to present, EP documents from 1978 forward, WO applications from 1989 forward and JP abstracts from 1976 forward. Search options include Basic, Advanced, Expert and Patent Number.

Search results can be filtered by source, assignee, date, and document type and sorted by relevance or date. A "QuickFlip" display option allows searchers to flip through displays of front pages very quickly.

Users who register for personal accounts (by invitation only) can take advantage of analytical tools, search histories, alerts and lists. For more information, see the press release.

Patent Filings Slow Amid Economic Slowdown

The worldwide economic crisis appears to be having an impact on international patent filings. This week the WIPO announced that the number of international patent application filings in 2008 increased by 2.4 percent, a big drop from the 9.3 percent average pver the past several years. However, the number of applications filed was 164,000, an all-time high. The countries with the largest increases were Korea (12%) , China (11.9%) and Sweden (12.5%). The U.S. experienced a 1 percent drop. Australia, Italy, Netherlands, UK also experienced declines. Canada had a very respectable 4.2% increase.

New Guide to Using Patent Information from WIPO

WIPO recently published a new 44-page guide to using patent information.

The guide explains what a patent is, the information contained in a patent document, where patent information can be found, and how to use basic patent search strategies. Almost half of the guide is devoted to explaining how patent information can be used.

It's a well-written, concise introduction to the benefits of using patent information.

Locating Re-examination Certificates

Patent attorney Stephen Nipper recently posted on his blog, The Invent Blog, a question about re-examination numbers. It seems that the USPTO website has some erroneous examples of re-examination document numbers.

In brief, anyone may file a request for a rexamination of a patent on the basis of prior art consisting of patents or other publications. The USPTO will examine the prior art and decided whether some, all or none of the claims of the patent in question should stand. At the end of the review the USPTO issues a re-examination certificate that sets forth the results of re-examination. This certificate is then attached to the original patent.

Re-examination certificates are not indexed in the USPTO's web-based patent database. Instead, users can retrieve a copy of the certificate by retrieving the original patent, e.g. by searching the patent number and clicking on the "Images" button to see the TIFF image. The re-exam certificate is attached after the claims section. (See 3,876,375.)

When a request for re-examination is filed, the USPTO assigns the case a control number preceded by a series code. The series code 90 is used for ex parte re-examination proceedings (90/009,335) and 95 for inter partes proceedings (95/001,115). Since 1981 there have been approximately 9,500 ex parte re-examinations filed. And 500 inter partes re-exams have been requested since November, 1999. The number of requests has nearly doubled in the last decade, increasing from 350 in fiscal year 1998 to 650 in 2008.

It is possible to retrieve re-examination filings in the USPTO's Public PAIR (Patent Application Information Retrieval) System. Simply search the re-examination control number (including the series code, e.g. 90/010334). The file wrapper will contain all the documents and forms involved in the re-examination, including a copy of the patent in question, submitted prior art, e.g. patents and non-patent literature.

Promoting IP Awareness - Database of Materials

The WIPO has a new database called IP Outreach in Practice which contains "basic information and links to practical examples of interesting IP outreach initiatives."

It's quite an interesting collection and a great place to look for inspiration and ideas. You can search by category (IP creation, IP use and awareness, IP crime), format (tv program, curriculum material, newsletter, etc.). There's an advanced search for more complicated queries.

WIPO wants to continue building the collection. You can send examples of outreach materials or initiatives to outreach@wipo.int.

Browser Toolbar for Patent Info Resources

Patent Pal is a new browser toolbar that links numerous patent information tools and resources. Included are over 30 patent search sites, numerous IP blogs and newsfeeds, patent office websites, manuals, job sites, and much more. Users can customize the toolbar and add their favorite sites. This is a very cool and useful tool... one of the best I've seen in years. Patent Pal can be downloaded from http://www.thepatentpal.com/.

Patent Databases: 2008 in Review

USPTO
Early in 2008 the USPTO installed verification software in its Public PAIR (Patent Application Information Retrieval) system that requires users to enter a two-word code in order to access patent and published application files. This was done in response to repeated bulk downloading by web spiders and automated scripts that severely degraded PAIR's performance.

WIPO PATENTSCOPE
In September, WIPO announced that the complete file contents of published international applications would be made available through the PATENTSCOPE search system. As of December 30, 2008 only the PCT request form is available. Other types of documents to be added include correspondence, copies of forms and original documents filed by applicants.

In December, WIPO announced that it would suppress inventor and individual applicant address information in PATENSCOPE due to privacy concerns. This will apparently not affect PATENSCOPE searches or RSS search alerts based on inventor address criteria. And address data will still appear on the frontpage of PCT published applications in PDF format.

On January 1, 2009 WIPO implemented three new kind codes (A4, A8 and A9) for republished PCT applications.

EPO esp@cenet
In October, EPO introduced a number of enhancements to the esp@cenet international patent database. These include increasing the number of documents stored in "My List" from 20 to 100; the ability to export data from search results (up to 30 records at a time); date range searching; highlighting search terms; and a single Google-like search box.

IP Australia
In April IP Australia launched a new patent search system called AusPat. Contents include bibliograhic data from 1970 forward and full-text data from about 1998 forward. IP Australia's old system, PatentSearch, will be retired in February 2009.

FreePatentsOnline
In September FPO increased the storage of individual accounts to a maximum of 20 portfolios and 10,000 documents. FPO also added a chemical search function. SumoBrain, another fee-based patent search system from the creators of FPO, introduced free individual user accounts.

Patents.com
Launched in September, Patents.com offers access to full text US utility, reissue and design patents, published applications (including plant patent applications) from 1976 to the present and European patent documents from 1998? forward. Search modes include simple, advanced and expert; about thirty searchable fields. A bulk search option allows users to retrieve multiple patents by number. Patents.com is the reincarnation of PatentMonkey.com, a patent search site that operated from early 2006 to January 2008.

Google Patents
Google Patents added US published applications but data is about six months behind.

U.S. Patent Counts - Year in Review

Figure 1. U.S. Patent (blue) and PGPub (red) Counts, Q4


2008 was a typical year for U.S. patents and published applications, but there were some surprises. The USPTO continued to churn out huge quantities of published applications (A docs), publishing slightly more than 312,000 applications this year, a 4.2 percent increase over 2007. On October 2 it published 8,955 applications, a record for a single week. In the fourth quarter, it published a record-breaking 84,780 applications, a 17 percent jump from the previous quarter and 15 percent more than the same quarter in 2007. Approximately 1.96 million plant and utilty patent applications have been published since 2001.

The number of issued patents (B docs) in Q4 rose to 46,556, a 13.9 percent increase from the previous quarter and a 2.5 percent rise from the same quarter last year. The total number of patents in 2008 dropped to 180,435, a 1.4 percent decrease from 2007.

Some milestones to watch for in 2009 will be the two millionth published application and patent no. 7,500,000, both of which will probably appear around the end of February. Plant patent no. 20,000 will probably issue in April and design patent no. 600,000 is expected this summer.

New Kind Codes for Republished PCT Documents

WIPO is introducing three new kind codes for republished international applications that will be implemented on Jan. 1, 2009. The codes are:

• A4 = Later publication of amended claims and/or statement (PCT Article 19) with revised front page
• A8 = International application republished with corrections to front page bibliographic data
• A9 = International application or ISR republished with corrections, alterations or supplements (see also WIPO Standard ST.50)

PatentScope Suppresses Inventor Address Data

WIPO has announced that due to privacy concerns it will remove address data for inventors and individual applicants from its PatentScope database. The data will not be indexed or displayed in Internet search engines. This will not affect PatentScope searches or RSS search alerts. I ran several test searches based on city names and postal codes and retrieved the expected documents, although address data did not appear in individual records. However, address data will still appear on the frontpage of PCT documents in PDF format.

It is unclear if this policy will apply to WIPO data obtained by third-party database producers such as FreePatentsOnline and Patent Lens. As of December 30, inventor address data from PCT documents was still indexed and displayed in Patent Lens.

FreePatentsOnline Launches CitePatents

FreePatentsOnline has launched a new site called CitePatents that is designed to make it easier for journalists, bloggers, copy writers and website owners and to link to patent documents. I hope this encourages more newspapers to link to patent documents in their stories. Too many journalists provide no details about related patents in stories about new products and infringement lawsuits. This wasn't always the case. Fifty years ago newspaper stories frequently included references to patent numbers.

Searching the USPC: Proximate Function

For novice patent searchers one of the most difficult concepts in the U.S. Patent Classification system is the idea that inventions can be classified on the basis of "proximate function." Proximate function is one of four schemes in the USPC used to classify subject matter disclosed in patents and published applications. The other three are "industry or use," "effect or product" and "structure." The rationalie behind proximate function is that "similar processes or structures that achieve similar results by the application of similar laws of nature to similar substances are considered to have the same fundamental utility and are grouped together." (See the Handbook of Classifiction.) For example, a refrigeration system used to cool beer and a refrigeration system that cools milk are treated the same under the USPC.

The patents of A.C. Gilbert, inventor of the Erector Set, offer another example of proximate function at work. Gilbert's inspiration for the Erector set was real-life construction sites he saw around his home in New Haven, Connecticut. Many of his patented inventions are simply scaled-down versions of construction materials such as beams, girders, brackets, trusses and rivets. Consequently, you can find Gilbert's patents classfied under both Class 446, Amusement Devices: Toys, and Class 52, Static Structures (Buildings). Because of the concept of proximiate function a search for patents for construction toys should include the appropriate subclasses from both classes. A third search possibility is the design class D21, Games, Toys and Sports Goods; subclasses 484-505 specifically relate to construction-type toys.

A.C. Gilbert - Inventor of the Erector Set and the "man who saved Christmas"

The other day when I was channel surfing I happened across a movie called The Man Who Saved Christmas, starring Jason Alexander as Alfred C. Gilbert, the inventor of the Erector set, one of the classic American toys of the 20th century. Gilbert became known as the "man who saved Christmas" during World War I when the U.S. government was considering a ban on the production of toys in order to support the war effort. Gilbert appeared before the Council of National Defense and successfully argued against the ban.

Gilbert was a Yale graduate and amateur magician who started with his partner John A. Petrie a business for producing magic tricks and apparatus. The company was named the Mysto Manufacturing Co. and based in New Haven, Conn. On Dec. 5, 1911, Petrie patented a disappearing cigarette trick (US1010794) and assigned the rights to Mysto. Gilbert's interest, however, soon turned away from magic and to construction toys. On Jan. 20, 1913, he applied for a patent for toy construction blocks. The application described toy building blocks made of strips of sheet metal and the means of fastening them together with u-shaped couplings. The patent issued on July 8, 1913 (US1066809), the first of more than 150 patents Gilbert would receive for Erector set components and other toys. The A.C. Gilbert company (Gilbert changed the name in 1917) continued to produce Erector sets , train sets and other toys into the 1960s.

Whatever happened to Gilbert's partner John Petrie? He parted ways with Gilbert in 1913 shortly after the introduction of the Erector set. He continued to invent and in 1917 patented an lighted hand mirror (US1216724) and a sand-wheel toy (US1247145). The trail grows murky after that. A John W. Petrie, also of New Haven, Conn. (possibly a son?), received several patents from the 1920s through 1940s for toys, magic devices and other items. Many of these were assigned to the Petrie-Lewis Manufacturing Co.

EPO Adds Latin American Patents

The EPO has added patent data from Cost Rica (CR), Peru (PE) and El Salvador (SV) to esp@cenet and some of its other patent data products. In addition, data from Cuba (CU) which had not been updated from 1996, will be re-introduced in the database at the end of December.

The actually number of patent documents added is small: 51 for Cost Rica (Mar-Aug, 2007), 110 for Cuba (Jan 2007-Apr 2008), 616 for El Salvador (2004-2007) and 94 for Peru (2004-2007).

Patented in China: New Report from Thomson Reuters

Thomson Reuters has published a new report called "Patented in China: the Present and Future State of Innovation in China." Patent filings from China have been growing faster than any other region in the last few years and if the trend continues it will become the "dominant country in the patent landscape" by 2012. The press release and PDF report are available at http://scientific.thomsonreuters.com/press/2008/8494659/.

The EPO's East Asian Patent Information portal has a number of FAQs and guides to Chinese, Korean and Japanese patents.

FreePatentsOnline Increases Personal Portfolios to 10,000 Documents

Individual accounts on FreePatentsOnline now can contain up to 20 portfolios and up to 10,000 patent documents. Users are still limited to exporting bibiliographic data from a maximum of 250 documents at a time. These improvements will be useful for searchers who maintain large collections of patent documents or who run multiple patent searches. Thanks, FPO!

Snow Bike Hits Slopes

Skiers and snowboarders may see something different on the slopes this winter... Two entrepreneurs from Vancouver Island hope to launch the next winter sports craze with their snow bike, a winter version of a mountain bike. Called the Ktrak, the bike is equipped with a ski in the place of the front wheel and a rubber track around the back wheel. Kyle Reeves, the inventor of the bike, has applied for patents in the US and Canada. He received a US patent on the rear drive assembly in 2007 (US7232130) and has a pending Canadian application (CA2497365A1) . Another pending CA application is for the front ski (CA2496740A1).

Betty James, Wife of Slinky Inventor Arnold James , Dies at 90

Betty James, wife of Richard James, the naval engineer who invented the world-famous Slinky spring toy in 1945, has passed away at the age of 90. Her obit is in the New York Times. Mrs. James named the toy 'Slinky'. The Slinky is one of the great toy invention success stories of the 20th century. In December 1945 Richard sold the first 400 Slinkys at Gimbels in Philadelphia in 90 minutes. Since then more 300 million Slinkys have been sold worldwide. Mrs. James took over as president of the business in 1960 when her husband abandoned the family and moved to Bolivia to join a religious cult. She served as president until 1998.

The patent (US2415012) on the Slinky is an excellent example of how vague patent descriptions can be. The title of the patent is 'Toy and Process of Use'. The text describes the Slinky as a 'helical spring toy,' referring to its coil-like shape. The name Slinky does not appear at all, since the original application was filed on November 1, 1945, probably before Mrs. James had selected the name. Patent Office rules discourage inventors from including trademarks and product names in the applications. For such a simply object, the patent has a surprising number of very detailed claims, 19 in total. The specification includes the dimensions of the original design and a detailed discussion of the mechanics of springs. It would be a useful teaching example for first-year engineering students.

Happy Thanksgiving!

Tomorrow is Thanksgiving in the States and in a few hours millions of Americans will be sitting down to a traditional turkey dinner. In honour of that noble and self-sacrificing bird, here are a few turkey-related patents. Of course, few people today actually hunt and kill their own turkey. But for those that do, there is this patented animated turkey decoy, US5289654, for luring reluctant gobblers into the open. If you prefer to have your bird and eat it too, there is this turkey trophy mounting kit, US5064725, for displaying the tail fan, beard and feet and an eye-catching "full strut" turkey plaque, USD566614. This attractive turkey figurine, USD314357, is the perfect center piece for any Thanksgiving table. And don't forget to bast your turkey using this turkey-shaped baster, USD390070.








Happy Thanksgiving! (USD527217)

Canada Dry Ginger Ale at 100

A little over one hundred years ago, John James McLaughlin, a Toronto pharmacist, created one of the world's most famous carbonated beverages, Canada Dry Pale Ginger Ale, the "champagne of ginger ales." McLaughlin started in 1890 manufacturing soda water and eventually decided to create a beverage with a little more pizazz. He experimented with more than 100 different formulas until he perfected his sparkling beverage in 1907. McLaughlin also invented and patented several machines for bottling his popular beverage. These include an apparatus for dispensing carbonated liquids (US736000 and CA83850) and a bottle washing machine (CA88234). He also acquired the rights to at least one patent for siphon filler (US678502). Canada Dry is now owned by Cadbury Beverages.

Patents and Biotech - a Broken System? Fixed by Information

A couple of months ago a Montreal-based non-profit IP consulting firm called The Innovation Partnership issued an interesting report calling for changes in the way biotechnology IP is created, disseminated and protected. In recent years there has been much debate in academic and research circles about whether the prolific patenting and licensing of biotechnology IP inhibits pure research and information sharing. The full report is available at:

Toward a New Era of Intellectual Property: From Confrontation to Negotiation - A Report from the International Expert Group on Biotechnology, Innovation and Intellectual Property

What struck me most about the report was the number of recommendations linked to the dissemination of patent information to the public. Specifically, the authors of the report argue that... "As custodians of the patent system, patent offices around the world should...

... build publicly-available databases of patent information that can be used to better track the impact and effectiveness of not only the IP system, but of particular methods of dissemination.

... should collect patent-related information in a standard form and make this available to the public for free. Data should include information that will assist in assessing patent landscapes in targeted areas of technology, such as essential medicines. Patent databases should be linked so that a user can identify not only the patents in one country but related patents in other countries. These databases should also be easily searchable.

...should collect data on the type and major terms of licence agreements. A pilot project at the Japanese Patent Office on creating such a database should be expanded and spread to patent offices around the world.

...To better enable patent offices to respond to the needs of the public sector, these offices
should establish policy branches that would investigate ways to make data more available, assist in patent landscaping and disseminate information about the patent system.

USPTO Annual Report FY2008 - 495,095 new applications!

The USPTO released its annual report for FY2008 and the numbers are staggering.

According to preliminary statistics, inventors filed a record-breaking 495,095 applications from Oct. 1, 2007-Sept. 30, 2008. This is a 5.7 percent increase over FY2007. Interestingly, there was a 33.7 percent increase in plant patent applications from 1,002 to 1,340. Design and utility applications increased about 5 percent. There basically no change in the number of reissue applications.

The number of applications pending has increased to 1,208,076, an 8.6 percent increase from last year. Pendency for UPR applications is 32.2 months. The highest pendency is 43.6 months in the Communications Technology Centre.

Issued patents dropped slightly to 182,556, keeping in line with the USPTO's drive to improve patent quality through more rigorous examination practices. Published applications increased to 309,194, a 2.2 percent increase. There was a big jump (25 precent) in the number of abandoned applications, suggesting perhaps that applicants are giving up on weaker applications. A total of 208,610 applications were abandoned as opposed to 166,000 last year.

The USPTO also hired another 600 patent examiners in FY2008. The total number of examiners is now 6,055. In 2004, the Patent Examing Corps numbered 3,753.

USPTO Issues 68 New Secrecy Orders in 2008

A blog posting at the New Scientist magazine claims that the USPTO issued secrecy orders on 68 new patent applications and rescinded 47 older orders in the year ending Sept. 30. A total of 5,023 secrecy orders are still in effect. The USPTO reports the number of secret cases in condition for allowance in its annual report, which is usually released in November. The annual report for 2006-2007 states that there were 3,081 such cases as of Sept. 2007.

End in Sight for IP Australia's PatSearch System

IP Australia has announced that it will update Patsearch, its legacy patent search system, weekly on Mondays starting Nov. 22, 2008. The system will be decommissioned in February 2009. AusPat, the new patent search system, was launched in April 2008 and contains bibliographic data from about 1970 forward and full text from 1998 forward. Australian patent documents are also available in esp@cenet and PatentLens (1998+). The Australian Patent Office was established in 1904. IP Australia has a long-term project to scan and make searchable all patent specifications back to this date.

Patent Offices Agree on Work Sharing Initiative

Joff Wild at IAM Magazine reports that the EPO, JPO, USPTO, SIPO and KIPO have just reached an agreement on a major work-sharing initiative that will reduce duplication and enhance patent examination. Part of the agreement includes the creation of 10 "Foundation Projects". The projects (as described in an EPO press release) that could have the most impact on public users of patent information include:

A) Common documentation database (lead: EPO)
Aim: To bring together a common set of relevant patent and non-patent literature from around the world to assist patent examiners in their prior art searches.

B) Common approach to hybrid classification (lead: EPO)
Aim: To enable joint and efficient updating of patent classification and facilitate the reuse of work among the patent offices.

C) Common Approach to Sharing and Documenting Search Strategies (lead: USPTO)
Aim: To promote reutilization by enabling the patent examiners of each office to understand each other's search strategy

D) Common Search and Examination Support Tools (lead: USPTO)
Aim: To establish a system of common search and examination tools to facilitate work-sharing

E) Common Access to Search and Examination Results (lead: JPO)
Aim: To enable examiners to find one-stop references in the dossier information of other offices, such as search and examination results.
To conduct the priority document exchange (PDX) to reduce the cost of ordering copies of priority documents for applicants and the administrative costs of electronic processing for offices.

F) Common Application Format (lead: JPO)
Aim: To facilitate the filing procedure of each office by using a Common Application Format; and by using electronic or digitized patent application filing (in XML format) and subsequent processing and publication in XML format.

New Esp@cenet Improvements

It's October... the time of year when patent searchers wait and watch for news from esp@cenet. The EPO rolled out its latest esp@cenet improvements this week.

The most impressive is a beta search function called SmartSearch. SmartSearch allows the user to enter terms such as inventor name, keyword, publication number, date, etc. in any order and without having to specify a search field for each term. For example, entering "Bombardier CA 2007" will cause SmartSearch to look for Bombardier as the inventor/applicant, Canadian patent documents (2 letters indicating the country code) and 2007 as the publication date.

Clicking on "Refine Search" in a SmartSearch search results list will take you to the SmartSearch search page where you can explore more features. There are 22 search field identifiers, some of them representing more than one field. For example, TA searches both title and abstract. A maximum of 21 search terms can be combined with Boolean operators and a maximum of 4 search terms per search field are allowed. Date range searching and proximity operators are only available at the EP level. Full text searching of the claims and specification is not possible. A maximum of five brackets can be used per search. Left truncation is not permitted.

esp@cenet also has added an export function that exports bibliographic data from up to 30 records at a time from search hit lists and documents stored in the "My Patents List". The fields include title, publication number, publication date, inventor(s), applicant(s), international classification, European classification, application number, date of application, priority number(s) and cited documents. The capacity of the "My Patents List" has been expanded to 100 documents (previously 20).

Esp@cenet also has a new logo celebrating its tenth anniversary.

SumoBrain Offers Free Registration

SumoBrain, the patent search system from the creators of FreePatentsOnline, is now offering free accounts. SumoBrain features full-text cross-collection searching of US patents and applications, EP patents and applications, PCT documents and Japanese abstracts, portfolios, alerts, and PDF download capabilities (for a fee). SumoBrain's content and search engine are very similar to FPO. And like FPO, registered users can save up to 1000 documents in 1-5 portfolios, and download bibliographic data from up to 250 records (at a time) in spreadsheet format.

Scientific Fraud and Patents

According to a report in the Oct. 2 issue of Nature, IP Australia is taking some heat for issuing a patent (AU2004309300B B2) to discredited Korean scientist Dr. Woo Suk Hwang that was based on fabricated data. In 2004 and 2005 Dr. Hwang claimed to have created a stem-cell line from a cloned human embryo. Hwang's claims, it was discovered, were a complete fraud. He lost his university job, was convicted of various crimes including embezzlement and his published papers were retracted. However, his university continued to prosecute patent applications based on his work.

Unlike scientific papers, patents are not peer-reviewed. Patent offices issue patents based on the legal criteria put for under national patent laws. They don't test the validity of the data submitted with a patent application. If they did, the patent system would probably grind to a halt. Of course, there are penalties for inventors who lie or commit misrepresentations in a patent application. But this usually applies to things like the date of conception of the invention, true inventorship, etc.

USPC Class Orders 1879, 1880

On Sept. 2, the USPTO issued Classification Order 1879 covering changes to design class D14, Recording, Communication, or Information Retrieval Equipment. New subclasses have been established for flash type memory drives, karaoke systems and digital media recorders. There are approximately 40,000 patents classified in Class D14.

The USPTO also published on Sept. 2 Classification Order 1880 covering a new cross-reference art collection labeled G9B, Information Storage Based on Relative Movement Between Record Carrier and Transducer. The order provides little information on the origin of this class, other than to say that it was established in 1979 and is connected to something called an IdT scheme, which is a European classification system. Obviously, it resembles an IPC class and not a USPC class. There are no patents classified in G9B at this time. Perhaps it is a new e-subclass.

U.S. Patent Counts, Q3 2008

The USPTO published 72,421 patent applications (A docs) in Q3, a 3 percent decrease over the same quarter last year and a 6.78 percent drop from the previous quarter. On October 2, the USPTO published a record-breaking 8,955 patent applications. If these had been counted in Q3, the total would have been a hefty 81,376. The USPTO is on track to publish over 310,000 applications this year. Approximately 1.87 million plant and utilty patent applications have been published since 2001.

The number of issued patents (B docs) in Q3 dropped to 40,869, a 17 percent drop from the previous quarter and a 6 percent decline from the same quarter last year. This was the lowest total in almost three years. Weekly issues remained flat for most of the quarter, dropping precipitously in the second half of September. The USPTO's campaign to hold the line on low quality patents appears to be having an impact on output.

Comparison of Free Patent Databases

Patent databases continue to proliferate on the internet. The most recent addition is Patents.com, which describes itself as "one of the most comprehensive free patent search services on the web." I get a little annoyed when I see claims such as this, especially when the database provider doesn't state the contents and dates of coverage. Having a great search engine doesn't mean much if the underlying data is incomplete. So I figured that it was prime time to update my comparison of patent database search engines.

When I did this last in February 2007 I compared Delpion, FreePatentsOnline, Google Patents, Patent Lens, Patent Monkey and the USPTO website. This time I compared five patent databases: Google Patents, FreePatentsOnline, Patents.com, Patents Lens and the USPTO patent database. Patent Monkey was absorbed by Patents.com in 2007. I decided to drop Delphion because it offers access only to US issued patents. Google Patents has added data for US published applications but it's unclear how frequently the data is updated. The other three non-USPTO databases are updated weekly.

All test searches were restricted to US patents issued from 1976 forward in order to allow for comparisons between databases. (Some databases include non-US patents and/or patents prior to 1976.) My search categories were inventor name, assignee name, keyword in title, and current US patent classification.

In the inventor search category, most of the databases came very close or slightly exceeded the results from the USPTO database. The only exception was Google Patents, which failed miserably at finding patents by inventor name. Perhaps Google has disabled their inventor name search.



Table 1. Inventor Name Search Comparison



Company name search results were also consistent across most of the databases. Again, the exception was Google Patents which found significantly fewer patents for two of the four companies searched. Patent Lens performed well except that it found approximately 200 fewer patents assigned to Bombardier than the other databases (except for Google). This might be explained by the fact that Bombardier's patent portfolio includes more than 200 design patents which are not covered in Patent Lens. FreePatentsOnline did poorly with "Queen's University", possibly because the apostrophe threw off the search engine.



Table 2. Company Name Search Comparison




The title keyword search produced varied results. Patent Lens, Patents.com and FPO did very well in three of the four searches. Google Patents found significantly fewer patents in all four searches. In a couple of searches FPO actually retrieved more patents that the USPTO database. But this might be because FPO searches withdrawn patents, which are not included in the USPTO database.




Table 3. Title Keyword Search Comparison



The best scoring database in the current US patent classification search was Patents.com, which produced identical or very close results to the USPTO database. FreePatentsOnline also did well, except when asked to retrieve patents in 623/1.1. The decimal subclass might have confused FPO's search engine. Google Patents and Patent Lens did poorly. Patent Lens does not index USPC or IPC codes, so the only way to search them is to do a crude keyword search against the front page. The results are next to useless.



Table 4. USPC Search Comparison




Overall, the USPTO database search engine produced the most reliable search results. Patents.com performs well for USPC and inventor name searches. Patent Lens is good for inventor, assignee and keyword searches but not USPC searches. FPO is almost as good as the USPTO database but punctuation may throw off search results. I would not recommend Google Patents for anything except retrieving PDF copies of known patents. Its search results are simply too unpredictable and incomplete.

The USPTO does score poorly in the patent document image category because its images are stored in TIFF format rather than PDF. Users must install a TIFF viewer in their browser in order to view patent documents from the USPTO website and then the documents must be viewed or printed one page at a time. The other four databases in this review support mutli-page PDF downloads.

Patents and Wall Street

We typically think of innovation as a good thing: Needs inspire ideas, ideas develop into inventions, inventions become patents, and patents make possible new products and services that enhance the quality of human life. But is innovation ever a bad thing? Well, yes, innovation can have a negative effect when it leads to unintended or unforeseen results. In some ways, innovation is to blame for the current U.S. financial crisis. During the past ten years the major players at the heart of the crisis--big Wall Street investment banks and financial companies--developed increasingly complicated and risky investment strategies based on the bundling and trading of mortgages. This has turned out to be a bust. Bankers have been pursuing other innovative strategies, as can be seen in a number of patents and published patent applications assigned to Wall Street firms. We don't usually think of bankers as inventors, but a change in the interpretation of U.S. patent law in the late 1990s (See State Street Bank & Trust Co. v. Signature Financial Group, Inc.) that allowed the patenting of so-called business methods inspired firms to apply for patents on everything from methods of predicting the value of mortgages to picking stock market winners and losers. Will we see fewer such patents in the future? Probably, since both the government and surviving firms will be much less interested in risky innovation.

Eco-Patent Commons

The World Business Council for Sustainable Development has developed an Eco-Patent Commons, a website where companies can pledge their environmentally-friendly patents to the public domain. So far, seven companies, Bosch, DuPont, IBM, Nokia, Pitney Bowes, Sony and Xerox have pledged about 75 patents.

Arctic Biotechnology Revealed in Patents

Could more effective medicines and tastier ice cream come from the belly of a shrimp living in the icy waters off Greenland? A new report called Bioprospecting in the Arctic, sponsored by the United Nations University Institute for Advanced Studies, looks at the current state of research into useful genetic materials found in plants, animals, fish and microbes living in the far north. Included in the report is a list of 31 patents and patent applications based on Arctic genetic resources, such as reindeer, northern shrimp, Artic fox, Arctic scallop, Atlantic cod and junipers. The list of patents is only the tip of the iceberg, so to speak. A quick esp@cenet search on some of the species named in the patents turns up dozens of additional documents. For example, there are at least ten patents related to the marine microbe rhodothermus marinus.

IPI-ConfEx 2009, March 1-5 - Venice, Italy

Registration is now open for next year's IPI-ConfEx, a patent information conference organized by European patent information professional associations. The host city is Venice-Mestre and the theme is "Best Practices in Patent Information Management and Searching." If you're seriously interested in patent information and can afford the airfare and registration, this is definitely an event to attended. Check out the testimonials from past conferences.

Patents.com - PatentMonkey Redux

There's (yet) another way to search patents on the internet: A new patent database/IP exchange portal called Patents.com has just launched. Patents.com is the brainchild of Robert Monster, a hi-tech venture capitalist, authority on market research and former product developer for Procter and Gamble, and Paul Ratcliffe, a patent attorney and founder of PatentMonkey.com, a patent search site that operated from early 2006 to January 2008.

Patents.com searches full text US utility, reissue and design patents, US applications (including plant patent applications) and European patent documents (from 1998 forward?). Detailed content information is lacking, but it appears that US coverage starts in 1976 (2001 for applications, of course). The most recent data retrieved was from patents issued on Aug. 26. EP coverage is more difficult to determine. Several test searches retrieved no patents before 1999. PDFs are available for US docs but not EP docs. Machine translation for fifteen langauges is offered.

Simple search allows simple word searches (no phrase searching or boolean operators). Advanced search allows users to search two or more terms using Boolean operators and wildcards. Expert search allows users to construct complicated fielded queries. Bulk search retrieves multiple documents by patent number. A cluster function groups keywords into a browsable list. At first glance, searches against US docs retrieve similar results as searches done in the USPTO database. It's more difficult to evaluate searches on EP docs as the coverage is unknown and there seem to be problems with some of the fields. I never could get the date range search to work properly.

Performance is faily fast, but the image view caused Firefox 3.0.1 to crash twice. There's a lot more to explore... for example the Community and IP Exchange sites...

Austrian esp@cenet Upgrade - New Content and Search Capabilities

According to an announcement on the esp@cenet web site, an upgrade to the Austrian esp@cenet server has added additional content and capabilities. It now contains AT A and B documents and utility models from 1995 forward. Advanced search features now include full text searching, date range searching and multiple keywords. Prost!

2008 World Patent Report

The WIPO recently released its 2008 World Patent Report, which contains all kinds of interesting statistics on patent activity worldwide. In 2006, a stunning 1.76 million new applications were filed worldwide, driven largely by filings in China, Korea and the U.S.

One of the most interesting sections covers patent filings per GDP, population and R&D. Both Japan (#1) and Korea (#2) had more than 2000 new resident applications per million population. (Japan 127 million pop. = / Korea pop. = 49 million) The U.S. (#3) managed just shy of 800 resident filings per million (with a pop. of 300 million). In R&D, Korea was the leader again, with slightly more than 5 applications per million $ of R&D funding. Russia, Japan, China and (surprisingly) New Zealand rounded out the top five. The US ranked #7 and Canada #29. Clearly, Asia is keen on generating IP.

All this demand is creating huge problems for patent offices. In 2006, the USPTO had more that one million pending applications, a 30% increase over 2004. Japan has about 800K pending applications, up from 600K in 2004. The EPO, on the other hand, has about 250,000 pending applications, which is about the same as 2004 and 2005. It takes about 40 months on average for the EPO to process an application but only 30 months at the JPO and USPTO. The Korean IP Office processes applications in about 20 months.

How are Engineering Librarians Using Patent Information?

A few months ago I surveyed my fellow academic engineering librarians to find out how they were using web-based patent databases in their day-to-day work with students and faculty. Patent literature has had a role in engineering education, especially design engineering courses, for many decades. Of course, before the mid-1990s when free patent databases started appearing on the web, most engineering students did not have easy access to patent information unless they were lucky enough to live near a patent depository library.

Forty people completed the survey. The results were pretty much what I expected. Academic engineering librarians are heavy users of patent databases. 57.5% reported giving workshops on patent searching to undergraduate engineering students, while 52.5% delivered workshops to graduate students. The most popular databases taught were the USPTO, Google Patents and FreePatentsOnline.

Librarians also reported frequent usage of patent databases to answer a variety of questions from students and faculty. 86.8% reported helping someone locate a patent document. 78% reported helping someone do a general search (inventor, keyword, assignee, etc.) and 52.6% reported helping someone do a patent search using classification. The most popular databases were the USPTO, Google Patents and esp@cenet.

When asked to rank desirable features of patent databases, librarians overwhelming (87.2%) suggested multi-page saving/printing of patent documents and (74.4%) making PDF the standard format. Other popular features included patent classification search tools and the ability to download/save search results.

The complete results of the survey are available at http://hdl.handle.net/1974/1377.

Patent Buddy Ranks Patent Attorneys

Patent Buddy is a new service that provides data (obtained from the USPTO) on registered patent attorneys and their employment histories since 2001. It claims to have data on 38,669 attorneys from ~13,000 organizations. You can search by name, registration #, organization, and geographic location. (You can search by Canadian city and postal code but not province, although it appears that provinces eventually will be added.)

Each individual is given an experience ranking, although it's unclear how this is calculated. You can also see their employment history, patents (although none I viewed listed any) and co-workers. Each organization is ranked by growth curve and experience. Again... details are sketchy about how the rankings are calculated.

More information is available in an article in Finance and Commerce, a Minneapolis-based business journal.

It's a very interesting start-up with a lot of potential... I think it would be especially useful to independent inventors and small firms shopping for a patent firm, and new patent attorneys job hunting.

Speedo's New Swimsuit Big Winner in Beijing

Speedo's new swimsuit, called the Fastskin LZR Racer, is grabbing attention at the Beijing Olympics. Two recently published US patent applications, US20080141431 and US20080141430, may reveal the technical secrets behind the innovative design that some say is responsible for the record-breaking performances of swimmers such as Michael Phelps of the US.

Inventors have been improving swimsuits for well over a hundred years, some less successful than others, as shown by this example from the 19th century. (US243834)

2008 World Patent Report

The World Intellectual Property Organization has released its 2008 World Patent Report. The 72-page report provides a statistical overview of worldwide patent activity, including the number of patent filings, granted patents, patent families, patents in force, patents by field of technology and the cost of patenting.

Proofreading Patents May Save Big $$$

The USPTO published more than 480,000 patent documents in 2007, so it isn't surprising that a few of them contain errors. Last year the PTO issued 23,000 certificates of correction (CCs), or about 12.5% of all issued patents. CCs are issued to correct typographical errors and other minor defects. However, a recent article citing a study published in the India Business Law Journal suggests that the number of defective patents is much, much higher and that uncorrected errors can be an expensive headache for patent owners. Unfortunately, CCs are not searchable in the USPTO website, although the scanned CC is appended to the original patent. CCs are also announced in the USPTO's Official Gazette.

Inventor's Last Wish: Bury me in my invention.

WIPO Magazine reports about the final wish of inventor Frederic Baur, a food chemist for Procter and Gamble. In 1966 Baur applied for a patent on a container for Pringles potato chips (US348798). Baur died in May at the age of 89 and requested that his body be cremated and his ashes buried in a Pringles can. I wonder if it was regular or Ranch flavoured?

Youngest Patent Holder?

The current issue of WIPO Magazine features a story about a boy who may be the world's youngest patent holder. Samuel Thomas Houghton of Buxton, UK was only three years old when he had an idea for an improved broom. His father, a patent attorney, applied for a GB patent, which was granted on April 2, 2008 (GB2438091).

It's impossible to know for sure if little Sammy is the world's youngest inventor since the inventor's age is not usually stated in patent applications. But I can think of at least one other very young patent holder from Minnesota. Steven Olson of St. Paul, MN, also the son of a patent attorney, was granted a patent in 2002 for a new "method of swinging on a swing" (US6368227). I believe that little Stevie was only 4 or 5 when his father applied for his patent. His patent is often cited by critics of the USPTO as an example of a low quality patent that should never have been issued. It does look like a vanity project, given that it's hard to imagine how one would go about commercializing such an invention. I guess it's no surprise that he let it expire in 2006.

Using RF to Treat Cancer

Last night Sixty Minutes did an interesting story on an inventor named John Kanzius who has developed a new radiofrequency therapy to treat tumors and cancerous cells. Kanzius, who has no technical or medical training, was inspired to invent by his fight with leukemia, a disease which still threatens to take his life. Kanzius has at least five US patent applications under review: 20050251233, 20050251234, 20050273143, 20060190063, and 20070250139. His earliest provisional application was filed on May 7, 2004. He also has two published EP applications and two PCT applications.

The treatment involves injecting a tumor with gold nanoparticles and exposing them to RF, which causes the cancerous cells to heat up and die. Adjacent cells are not harmed. The therapy has shown encouraging results in the lab, much to the amazement and delight of canceer researchers.

It just so happens that I am currently reading Margaret Cheney's excellent 1981 biography of Nikola Tesla, Tesla, Man Out of Time. Tesla was an early pioneer of wireless communication in the 1880s and 1890s and believed in the possibility of wireless transmission of electricity. He also speculated that radiofrequency waves might be used to treat human disease, although he never followed up on the idea. I think it's fascinating that more than one hundred years later someone might actually fulfill Tesla's vision.
