Main provisions of legislation passed Tuesday by the Senate to overhaul the patent system:
_Changes the patent application process from a first-inventor system to the first-inventor-to-file system that is used by all other industrialized nations in the world.
_Gives the director of the U.S. Patent and Trademark Office authority to set fees so as to provide the resources needed to reduce the backlog of patent applications.
_Ends the practice of diverting fees paid to the patent office to other government spending.
_Allows third parties to submit information to challenge pending patents.
_Creates a "first-window" post-grant opposition period of nine months to weed out patents that should not have been issued.
_Establishes an administrative review process for challenging the validity of a patent, with a higher threshold for initiating a proceeding and the goal of reducing the litigation costs of drawn-out court challenges.
_Bans the issuing of patents for tax strategies.
