USPC Patent Quality Benchmark Study

Rank of Top 25 USPC by IPQ® Score 2011

Ocean Tomo, the Intellectual Capital Merchant Banc™ firm, undertook a study of current patent quality and historical trends among the 430 US Patent Classes as defined by the USPTO. The Ocean Tomo Patent Quality Study provides a meaningful benchmark for those studying patent quality among the 430 US Patent Classes as defined by the USPTO. The study identifies Nanotechnology (class 977) as the number one technology class for patent quality, with the highest current average IPQ® score. The quality of this sector reinforces the USPTO’s recent addition of nanotechnology as a designated class. An average IPQ score of 126.6 is equivalent to the top 20% of all US rated patents. The top 25 technology classes are directionally significant, having an average IPQ score above 120 puts each among the top 30% of all rated patents.

The study was performed using the Ocean Tomo PatentRatings® system, the first market-validated software platform for objectively assessing patent quality, relative value, and competitive trends for patents, patent portfolios, companies, and technology sectors.The Ocean Tomo PatentRatings® System uses a patented method of patent quality valuation, (USP 6,556,992 7,657,476 and 7,716,226 and other US and foreign patents pending) that is statistically based to calculate the relative quality of all patents issued by the U.S. Patent Office since 1976 using more than 50 independent and objective factors that are correlated to patent quality.

1.  USPC: United States Patent Classification System, a system for organizing all U.S. patent documents and many other technical documents based on common subject
matter. Classes with patent count below 10 are excluded from this analysis. Based on 423 discrete US patent classes (technologies per USPTO) with average patent count
of approximately 15K per class.
2 .  Description: a detailed description of the subject matter that must be in a patent document in order for the document to be properly classified in the USPC system.
3 .  Avg IPQ® Score: Average IPQ 2011 issued & in-force US patents within designated USPC group through 6/28/2011. The IPQ Score is the output from Ocean Tomo’s
PatentRatings® system, uses 50 independent and objective factors that are correlated to patent quality, where 100 is a median quality above 100 indicates above average
quality relative to all issued US patents.
