Rulings called threat to innovation

WASHINGTON — The Supreme Court on Monday delivered two decisions that experts say weaken the value of patents, fueling criticism that technological innovation, particularly in the biotech and pharmaceutical sectors, could be hindered.

In the more important of the two cases, the court made it simpler for companies to challenge patents on the grounds that they cover products that are obvious combinations of existing technologies. Under U.S. law, an invention must be new, useful and not obvious in order to merit a patent. The case involved Canada-based KSR International Inc. and Teleflex Inc., based in Limerick, Penn.

In the second case, the court curtailed the reach of U.S. patent laws overseas, ruling in favor of Microsoft Corp. in its dispute with AT&T Inc. over Microsoft's sale of Windows software outside the United States that allegedly infringed AT&T's patents. The decision will likely reduce damage awards in patent cases by excluding patent infringement overseas from consideration.

Boston University law professor Dennis Crouch wrote on a popular Supreme Court blog, Scotusblog, that "because of KSR, patents will be more difficult to enforce and easier to invalidate."

"The AT&T case," he added, "cuts in half the value of many of today's most valuable software patents."

The Supreme Court's recent interest in patent law — it has taken up a half-dozen cases in the field in the past two years, an unusually large number — reflects the greater role patents play in the U.S. economy, as companies earn more revenue from licensing patents and patent litigation has increased by 50 percent in the past ten years.

IBM Corp., which regularly tops the annual list of top U.S. patent recipients, receives approximately $900 million in revenue from licensing its patents and other intellectual property to other companies. David Kappos, assistant general counsel at IBM, said that figure is an increase from the "low millions" in the early 1990s.

Microsoft is a big winner in the two decisions today. The court's ruling in the AT&T case throws out the use of worldwide product sales as a basis for calculating damages in patent infringement suits, a formula that has resulted in large judgments against the company in other cases.

A jury hit Microsoft with $1.52 billion in damages earlier this year in a suit filed by Alcatel-Lucent, and a separate jury awarded Eolas Technologies Inc. and the University of California $521 million in damages from Microsoft. Both damage awards were calculated based on worldwide sales of Windows software.
