Mayer Brown Legal Update
On September 16, 2011, President Obama signed the Leahy-Smith America Invents Act (the Act) into law. The Act provides the most substantial change to the patent laws of the United States since the Patent Act of 1952. Most significantly, it transforms the US patent system from a “first-toinvent” to a “first-to-file” regime. In addition, the Act provides several new review processes by which the validity of issued patents may be challenged.
