U.S. top court to hear business method patent case

By Diane Bartz

WASHINGTON (Reuters) - Software, biotech firms and others who develop new ways to do business will be watching closely on Monday as the U.S. Supreme Court hears a case that could determine if such innovations can win patent protection.

The case itself involves a small Pittsburgh company called WeatherWise, founded by Bernard Bilski and Rand Warsaw, to sell services based on hedging methods that allow users to make fixed energy payments even if usage or energy prices vary.

But when they tried to patent the hedging method, the U.S. patent office rejected it in 2000. The patent board upheld the rejection in 2006.

The battle continued up to the U.S. Court of Appeals for the Federal Circuit, which in 1998 had broadened the definition of what was patentable to anything except laws of nature and abstract ideas.

But, after hearing the Bilski case, the court, which specializes in patent appeals, sought to set limits. It ruled that the hedging method could not be patented because it was not tied to a machine and did not result in a transformation.

The Federal Circuit decision threw doubt on tens of thousands of business method patents, like software patents and medical diagnostic patents. One of the best-known examples of a business method patent is Amazon.com Inc's (AMZN.O: 株価, 企業情報, レポート) one-click process to buy goods on the Internet.

"I did some math this morning and the market cap of the companies that filed (friend of the court) briefs is $1.2 trillion," said Marc Pernick, a patent attorney with law firm Morrison Foerster.
