The U.S. Supreme Court upheld an administrative review system that has helped Google, Apple and other companies invalidate hundreds of issued patents. From a report: The justices, voting 7-2, said Tuesday a U.S. Patent and Trademark Office review board that critics call a patent "death squad" wasn't unconstitutionally wielding powers that belong to the courts. Silicon Valley companies have used the system as a less-expensive way to ward off demands for royalties, particularly from patent owners derided as "trolls" because they don't use their patents to make products. Drugmakers and independent inventors complain that it unfairly upends what they thought were established property rights. "It came down to this: Is the patent office fixing its own mistakes or is the government taking property?" said Wayne Stacy, a patent lawyer with Baker Botts. "They came down on the side of the patent office fixing its own mistakes." The ruling caused shares to drop in companies whose main source of revenue -- their patents -- are under threat from challenges. VirnetX, which is trying to protect almost $1 billion in damages it won against Apple, dropped as much as 12 percent. The patent office has said its patents are invalid in a case currently before an appeals court.
