Five Democrats and four Republicans introduced the Patent Reform Act of 2009 in Congress Tuesday (March 3.). They will hold a one-day hearing broadcast over the Web on March 10.

As reported last week, the Act in most respects picks up where the debate left off in Congress. The new bill includes many of the provisions in HR 1908 that was passed in the House in September 2007 and its companion bill--S.1145--that failed to make it to the Senate floor for a vote in 2008.

Within hours after the new bill was introduced, two industry groups and two members of the House of Representatives came out against the new measure. The issue of damages quickly emerged as the central issue.

Big computer and communications companies back the bill as a way to limit the number of patent infringement cases and damages they pay on them.

"We are the constant target of patent lawsuits, many of which are frivolous and more than half are filed by non-practicing entities," said Mike Holston, general counsel of Hewlett-Packard and a member of the Coalition on Patent Fairness that backs the bill. "We have to divert significant time and money to deal with these lawsuits," he said in a press conference sponsored by the group.

HP holds about 30,000 patents and is granted an average of four every day, he added.

"We find ourselves in a situation with more patent infringement suits than ever before and each one costs as much as $4 million," said John Thompson, chief executive of software developer Symantec, another member of the coalition.

On Feb. 17, Thomson hosted a $10,000 a plate fundraiser in his Silicon Valley home for Senator Patrick Leahy (D-Vt.), one of the sponsors of the new bill. Thomson said he did not know how much the event raised, but more than 75 representatives of Valley companies attended the event.

Opponents claim the mechanism called apportionment the new bill uses to determine damages won't work outside the computer and communications industries where hundreds of patents go into a single system.

"If you go to any other industry the amount of patents is small--it might be five or even one, said Tom Kelly, general counsel of Monsanto and a member of the Innovation Alliance, a group of technology licensing companies including Dolby Labs, Qualcomm and Tessera that organized a separate press conference.

"My fear is a jury will inevitably say there are a thousand components in an infringing product so you get one one-thousandth of its value in damages," said Stan Findley, general counsel of Corning Inc., another member of the group. "It's not fair. We're not persuaded apportionment in a vacuum is a good idea."
