Businessweek Analytics

In January 2010, Bloomberg Businessweek asked Ocean Tomo PatentRatings® to rank the World's Top 25 Most Inventive Companies using its proprietary PatentRatings® system.

By studying the patents issued to a company over the past five years, Ocean Tomo PatentRatings determined how inventive a firm is using its proprietary patent quality measure, the IPQ® score.

Methodology for Top 25 Most Inventive Company Selection

The Top 25 Most Inventive Companies were selected from the 1,000 listed companies with the greatest revenue over the most recently reported trailing one year period (9/2008 to 9/2009). These firms were rank ordered based on an analysis of their patent portfolio over the past five years using the PatentRatings system to calculate the relative quality of all patents issued by the U.S. Patent and Trademark Office. The system analyzes more than fifty independent and objective factors. Scores are based on identified predictor variables (“metrics”) determined to have statistically significant correlation to the payment of patent maintenance fees (periodic taxes paid to the U.S. Patent Office).

The premise of the rating model is that more valuable, higher-quality patents will be maintained at a higher frequency (have a longer lifespan) than less-valuable patents. Typical metrics include the number, length and type of patent claims, the presence or absence of limiting claim language, the patent prosecution history, the technology classification, the growth rates and filing of new applications in a given technology space, and more than thirty other relevant factors. PatentRatings system patent quality scores are calculated by multiplying statistically-determined coefficients with variables representing each of the relevant metrics, and then by normalizing the resulting values to an appropriate scale.
