mpicpp (3454017) writes "Dozens of companies were sued over an old Polaroid digital imaging patent.
The most litigious "patent troll" in the US has lost a major case after the US Court of Appeals for the Federal Circuit found its patent was too abstract.
Court declines to stop software patents altogether.
The ruling from last week is one of the first to apply new Supreme Court guidance about when ideas are too "abstract" to be patented. In the recent Alice v. CLS Bank case, the high court made clear that adding what amounts to fancy computer language to patents on basic ideas shouldn't hold up in court.
The patents in this case describe a type of "device profile" that allows digital images to be accurately displayed on different devices. US Patent No. 6,128,415 was originally filed by Polaroid in 1996. After a series of transfers, in 2012 the patent was sold to Digitech Image Technologies, a branch of Acacia Research Corporation, the largest publicly traded patent assertion company. A study on "patent trolls" by RPX found that Acacia Research Corporation was the most litigious troll of 2013, having filed 239 patent lawsuits last year."
