Indexing Innovation

Technology Review has teamed with CHI Research of Haddon Heights, NJ, to produce the Patent Scorecard, an industry-by-industry ranking of corporate patent portfolios. CHI combines the number of a firm’s patents with other indicators to flesh out this deeper picture of innovation. Here are the specifics:

Technology Strength: This figure, the basis of the rankings, provides an overall assessment of a firm’s intellectual-property power. It is calculated by multiplying the number of a company’s U.S. patents by its Current Impact Index (see below).

Number of Patents: The total number of U.S. patents awarded, excluding design and other special-case inventions.

Current Impact Index: This measure showcases the broader significance of a company’s patents by examining how often its U.S. patents from the previous five years are cited as “prior art” in the current year’s batch. A value of 1.0 represents average citation frequency; so 1.4 would indicate a company’s patents were cited 40 percent more often than average, and so on.

Science Linkage: Patents sometimes cite scientific papers as prior art. This value shows the average number of science references listed in a company’s U.S. patents. A high figure indicates the company is closer to the cutting edge than its competitors.

Technology Cycle Time: An indicator of a firm’s speed in turning leading-edge technology into intellectual property, defined as the median age (in years) of the U.S. patents cited as prior art in the company’s patents.
