Here is a checklist of a few key changes:
1. Establishing a ‹rst-to-‹le system 2. Eliminating the ability for anyone to ‹le false marking lawsuit 3. Filing by other than inventor for corporations to ‹le oath and declaration 4. Eliminating the best mode requirement 5. Eliminating interference proceedings 6. Expanding prior user rights as a defense to infringement 7. Creating new USPTO proceedings for post-grant review
