Boliven Patent Goes Commercial

Boliven Patents is now a "professional-grade" fee-based service, according to an e-mail sent yesterday to current members of the Boliven Network. The service was launched in January as a free beta patent search engine with integrated analytical tools, search alerts and data export functions. It now includes more than 60 million patent documents from the US, Europe, Japan, Korea and others. Recently added data includes INPADOC/DOCDB data and US patent assignments.

Current members will have complimentary access for three months, after which they must pay $60 per month on a month-to-month basis. New users will be eligible for a free two-week trial period.

This isn't surprising news, given that Boliven is a private firm with a pretty obvious business plan. But I was hoping that the beta period would last longer or that part of the service would remain available to the public. This development underscores the danger of relying on third-party patent database providers to provide access to public patent information. They can disappear at any moment. Will FreePatentsOnline or Patent Lens be next?

New Website Compares Patent Search Systems

Landon IP, a private firm specializing in patent and trademark searches and patent analytics, has launched Intellogist, a free website that aims to help patent searchers locate sources of patent information, evaluate public and commercial patent search systems and exchange best practices in prior art searching. This service will be useful to both novice and experienced patent searchers. The site is supported in part by advertising.

USPC Class Order #1886

The USPTO has published Classification Order #1886, which affects subclasses in Class 439 - Electrical Connectors. As of April 8, there are approximately 76,000 patents and 17,000 published applications classfied in Class 439, which is the "generic class for a pair of mated conductors comprising at least two electrically conducting elements which are interconnected to permit relative motion of such conducting elements during use without a break in electrical conductivity." The earliest patent in this class is RE200 issued in 1851 to George H. Corlis of Provdence, Rhode Island for an improvement in cut-off values in steam engines.

US Patent Counts, Q1 2009

The number of US patents (B docs) issued in Q1 was 49,227, a 13 percent increase over 2008. However, this may be only a temporary blip. The USPTO's campaign to improve patent quality has increased the number of rejections to a level not seen in several decades. The USPTO's allowance rate at the end of 2008 was about 44.2 percent, a steep decline from 2000 when the allowance rate was 72 percent. And there is a growing belief that the current worldwide recession will cause a 5-10 percent decline in the number of new applications in 2009, which may ultimately lead to fewer issued patents.

The USPTO issued patent no. 7,500,000 on March 3.

The number of published applications (A docs) dipped slightly to 83,855, an 8 percent increase over 2008. Approximately 2,042,000 million plant and utility patent applications have been published since 2001. The two millionth application was published in February.

IPC Reforms Aim to Integrate USPTO, EPO and JPO Classifications

WIPO just announced a series of reforms that will simplify the IPC. One of the goals is to accelerate the building of a unified IPC system that integrates USPTO, EPO and JPO classifications.

Could a true international patent classification system be at hand?

This is a positive step and should make life easier for patent searchers of all levels of experience, from novices to experts. The need to work in four different systems is challenging even for experienced searchers.

However, there is a potential risk that some of the information currently embedded in local classification systems might be lost.

Trademarks Go Green

World Intellectual Property Day is April 26, just over a month away. This year's theme is green innovation. The environment and climate change have become major political and public opinion issues in the over last few years. Companies and advertisers have certainly noticed this trend and are keen to link their products and services with environmentally friendly values. More and more products are being branded as "green". You can see this trend in trademark filings. As the chart below shows, the number of US and Canadian trademark applications filed for marks containing the word GREEN increased dramatically in the last few years. In 2007 alone, the number of filings increased in the US 131 percent and in Canada 88 percent.

Canadian Patents Reach 18,554 in 2007-2008

The Canadian Intellectual Property Office released its annual report for 2007-2008 earlier this year. The number of patents granted in 2007-2008 was 18,554, up from 16,100 in 2006-2007. The United States ranked first with 8,534 patents, or 46 percent of the total. Japan was second with 1,814 followed by Canada with 1,813. Almost 90 percent of Canadian patents were granted to foreign inventors.

USPC Class Order #1886 - Class 439

The USPTO has published classification order #1886, affecting Class 439 - Electrical Connectors. This order replaces subclasses 607-610 with subclasses 607.01-607.59. Approximately 1,650 patents were classified as original references in the reorganized subclasses. There are approximately 76,000 patents currently classified in Class 439.

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.
