April 29, 2010 - Patrick Leahy (D-VT), the Senate Judiciary Committee Chairman, came to an agreement with the committee's ranking Republican, Jeff Sessions (R-AL), on a compromise bill - making passage of the Patent Reform Act of 2009 likely this year.
The Senate bill, S.515, increases the "gatekeeping" role of judges in determining whether claims of damages are well-founded. Other major changes included in the bill are a change from a first-to-invent to a first-to-file system, and the creation of a system of post-grant review to determine patent validity.
