Patent law has gone through a revolution in the last two decades. The U.S. Supreme Court has reasserted limits on eligible subject matter while modernizing the standards for basic conditions of patentability such as obviousness, enablement, claim indefiniteness, exhaustion, and secondary liability. The courts and the USPTO continue to absorb the historic changes made by the America Invents Act, including the shift to first inventor to file and upgraded post-issuance patent review proceedings. Now more than ever there is a need for expert guidance in navigating the patent system.
