【 摘 要 】

A letter report issued by the Government Accountability Office with an abstract that begins "From 2000 to 2010, the number of patent infringement lawsuits in the federal courts fluctuated slightly, and from 2010 to 2011, the number of such lawsuits increased by about a third. Some stakeholders GAO interviewed said that the increase in 2011 was most likely influenced by the anticipation of changes in the 2011 Leahy-Smith America Invents Act (AIA), which made several significant changes to the U.S. patent system, including limiting the number of defendants in a lawsuit, causing some plaintiffs that would have previously filed a single lawsuit with multiple defendants to break the lawsuit into multiple lawsuits. In addition, GAO's detailed analysis of a representative sample of 500 lawsuits from 2007 to 2011 shows that the number of overall defendants in patent infringement lawsuits increased by about 129 percent over this period. These data also show that companies that make products brought most of the lawsuits and that nonpracticing entities (NPE) brought about a fifth of all lawsuits. GAO's analysis of these data also found that lawsuits involving software-related patents accounted for about 89 percent of the increase in defendants over this period."
