    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.

    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.

    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.
