"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."
