| The number for 2006 U.S. Patents is a proxy for relative patent prowess worldwide. The Pipeline Power score is derived by multiplying the company’s patent count by the product of four other variables. Pipeline Growth (not shown here) represents the firm’s 2006 patent activity, relative to its average performance in the five previous years. For the other three variables, a score above 1.00 indicates that the company performed better than average in its technology class; below 1.00 indicates worse than average performance. Pipeline Impact indicates how frequently all 2006 patents cited a company’s patents from the previous five years. Pipeline Generality is a measure of the variety of technologies drawing on a company’s patents. Pipeline Originality measures the variety of the technologies upon which an organization’s patents build. Adjusted Pipeline Impact eliminates self-citation. The final score, Adjusted Pipeline Power, is an estimate of a company’s overall patent power. For the complete data, which include all of the top 20 companies in each category, as well as the Pipeline Growth and percentage of self-citation numbers, see http://spectrum.ieee.org/nov07/scorecard. |
