IBM Leads in Patent Strength According to Independent Ranking

Select a topic or year

ARMONK, NY - 23 Apr 2003: IBM has the world's strongest and most influential patent portfolio, according to a scorecard published by MIT Technology Review and CHI Research.

According to the "2003 Patent Scorecard," published in the May 2003 issue of Technology Review, IBM's patent technology strength is more than double of the next closest computer company (Hewlett-Packard). IBM also outpaced the combined portfolio scores of HP, Sun, Microsoft, EMC, Dell and Oracle.

Technology Review created the scorecard by teaming with CHI Research to produce an industry-by-industry ranking of corporate patent portfolios. CHI combines the number of patents a company receives with other indicators to generate a tangible measurement of innovation.

The patent "Technological Strength" ranking on the scorecard provides an overall assessment of a company's intellectual-property power. It is calculated by multiplying a company's total U.S. patents by its "Current Impact Index," which CHI determines by examining how often the company's patents from the previous five years are cited by other inventors as prior art in the current year's batch.

"We've long maintained that the true measure of innovation is more than just the accumulation of patents," said Nicholas M. Donofrio, senior vice president, technology and manufacturing for IBM. "The 񟭃 Patent Scorecard' validates that IBM's patent portfolio is a source of great value to other inventors, to competitors who license our intellectual property and to customers who reap the benefits of our innovation."

IBM inventors were issued the most U.S. patents in 2002, the tenth consecutive year that the company led the world. In the past decade, IBM inventors have received a record 22,357 patents, besting the next closest company, Canon, by nearly 7,000 patents. During this period, IBM has generated more patents than 10 of the largest U.S. IT companies combined, including Hewlett-Packard, Intel, Sun, Microsoft, Dell, Apple, EMC, Oracle and EDS.

IBM is the only company to be granted 3,000 U.S. patents in a single year, passing that milestone each of the past two years.
