PatentScope Adds Canadian National Collection

An early Christmas present from the WIPO:

PatentScope now includes the Canadian national collection from ~1920 forward. No PDFs yet, it appears, but full text (based on OCR) is available for some patents. A few pre-1970s patents have IPC codes, so keyword searching may be required for some types of searches. This gives researchers another option for searching Canadian patents from the early 20^th century forward.

Other national collections to be added in the next few months include the Eurasian Patent Office, Germany, and UK.

Improved Peanut Butter Jar?

A pro-hockey player and inventor from Alberta thinks he's solved a problem that has plagued kids forever: how to get the last bit of peanut butter out of the bottom of the jar without getting it all over your fingers. The Toronto Star reports that Darren Kramer has applied for a patent on an improved peanut butter jar. The jar's top half twists off to allow easier access to peanut butter in the bottom.Kramer isn't the first inventor to tackle this problem. In 2009, Ryan Coffey of Wisconsin filed an application (US2009261098  A1) for a jar (that closely resembles the peanut butter kind) with lids at both ends, presumably to allow for easier access to the peanut butter at the bottom. 

Great Canadian Inventions Profiled in Globe and Mail

The Globe and Mail has launched a new monthly feature profiling great Canadian inventions and inventors. The first inventor profiled is Al Gross (1918-2000) who pioneered the development of two-way radio systems (walkie-talkie) in the 1930s. Mr. Gross, who was also known as Irving J. Gross, received several radio-related patents in the 1940s and 1950s which were assigned to the Stewart-Warner Corp. of Chicago. (See US2698380, US2760058, etc.) "The Innovators" series is located at http://tgam.ca/innovators.

World Cities Ranked by Patent Productivity

Today's Globe and Mail published an interesting list of 24 cities ranked by the number of U.S. patents per 100,000 population. The top ranked Canadian city was Vancouver (11th), followed by Toronto (12th), Calgary (13th), Montreal (15th) and Halifax (20th). Seven of the top ten cities were in the U.S. There were some surprising omissions. Houston, for example, didn't make the list despite its high patent output. And San Diego and the Research Triangle area in North Carolina, home to many research universities and biotech companies, were also missing.

It's easy to dismiss such rankings as U.S.-centric because they're based only on USPTO data. But the fact is that many Canadian inventors and companies file applications first in the U.S. According to the USPTO's Fiscal Year 2010 annual report, Canadians filed 11,250 applications in 2009. In comparison, the CIPO received 5,215 patent applications from Canadian residents in 2009-2010.

It would be interesting to re-calculate this list based on PCT data from PatentScope. Cities with high filings of PCT patent applications per 100K pop. might indicate concentrations of companies with global rather than national or regional patent strategies.

Canadian Inventor/Designer Robert Dickie

The Globe and Mail's business magazine has an interesting profile of Canadian inventor and industrial designer Robert G. Dickie. ("The Business of Brainstorms", April 29) Dickie's firm, Spark Innovations, is responsible for designing dozens of products ranging from electric toothbrushes to medical devices. He has 51 Canadian patents and published applications, 84 US patents and 62 published applications, and has filed dozens more around the world. He also has some unconventional ideas on what makes a successful invention and inventor.

Fostering Canadian Innovation

Today's Globe and Mail has another op-ed piece arguing that Canada needs to do better at promoting innovation and investing in R&D. ("Innovation is Our Hidden Deficit") It's probably true that Canada could do more at home to support innovation and the commercialization of new products. But the picture improves when you look at Canada's performance on the world stage.

For example, Canadian inventors and companies file more patent applications in the U.S. than they do in Canada. In 2007-2008, Canadian inventors filed 11,436 new patent applications with the USPTO but only 5,086 with the CIPO. This is not surprising given that most Canadian companies are eager to protect their IP in the US market. A strong portfolio of US patents will foster new partnerships, investments and business opportunities.

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.

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.

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).

Canadians Too Lazy to Invent?

A recent op-ed in the Globe and Mail (Dec. 27) uses patent statistics to make the case that Canada, in general, and the province of Alberta, specifically, needs to focus more on math, science and the creative arts in schools in order to ensure future prosperity. The writer argues that since Canada is about one-tenth the size of the U.S., Canadian inventors should have been granted 240,000 U.S. patents over the last twenty years. Instead, they have received only 77,594.

Although I agree that Canada needs to do more to cultivate innovation rather than rely on natural resources for economic growth, I'm generally skeptical about such comparisons. In fact, I believe that patent statistics show that Canadians are among the most inventive, creative people in the world.

Let's take a broader look at patenting trends among the G8 countries over the last few years. With just over 33 million people, Canada is the smallest country in the G8, yet since 2000 Canadian inventors have been granted nearly as many U.S. patents as their counterparts in France and Great Britain, which have populations almost twice as large. In terms of the per capita number of patents issued, Canada, with about 1000 people per patent, ranks second after Japan (488:1) and Germany (857:1) and well ahead of France (1702:1), Italy (3458:1) and Russia (60991:1).

A much more interesting statistic, in my opinion, is the fact that Canadian residents apply for and receive far fewer patents in Canada than the U.S. In 2006, Canadian inventors filed 10,243 U.S. patent applications and were granted 3,743 patents, but filed only 5,348 Canadian patent applications and received 1,495 patents. Obviously, this might be explained by the fact that Canadian inventors believe they can get more bang for their buck in the U.S., where the consumer and venture capital markets are much larger.
