To follow on our earlier post (US Patent Update), the America Invents Act (the US patent reform bill) has passed and was signed into law by President Obama on September 16th. Among the changes:

• Adopting a “first to file” system (from the previous “first to invent” system), which bring U.S. patent law into line with many international patent laws; a one-year grace period is built into the legislation to allow for the transition;
• Changing some aspects of the test for patentability and the assessment of prior art;
• The rules regarding confidential sales have been amended – such sales prior to filing of a patent application will not be considered a bar to patentability.
