If you have an invention that may warrant patent protection, consider filing an application before March 16, 2013. Why? The implementation of the America Invents Act on March 16, 2013 marks the shift of the U.S. Patent system from first-to-invent to first-inventor-to-file. For some, this may represent an advantage to be had in filing for a patent before the March 16 deadline. Justin McCabe of SRH Law explains in greater detail here.
