billstewart writes "The US Senate passed a patent-reform bill, S.23 aka "America Invents", which changes US patents from First-to-Invent to First-to-File. (thomas.loc.gov Status Query, Computerworld Article, National Journal with comments pro and con, SF Chron). Patrick Leahy sponsored it. Passed 95-5, House expecting to introduce similar bill Real Soon. Silicon Valley businesses large and small were mostly against it, IBM was for it. Dianne Feinstein attempted an amendment to remove the First-to-File part, but voted for it anyway after that failed. Barbara Boxer voted against.
The US patent system has been first-to-invent for a long time, while Europe has been first-to-file. There's lots of other detail, largely intended to reduce the amount of patent litigation, improve the coordination with non-US patents, potentially improve the problems with patents on things with prior art and obviousness, and affect some tax issues."
