Last Chance For 'First-To-Invent' Patent Protection Rapidly Approaches

On March 16th, the final provisions of patent reform under the Leahy-Smith America Invents Act of 2011 go into effect, transitioning the United States from a "first to invent" patent system to a "first to file" patent system and broadly expanding the scope of prior art, i.e., information available to the public, that can be used to reject patent applications filed on and after that date. The impact of these changes should motivate inventors to file new patent applications by March 15th to take advantage of the benefits of the present system.

Patent regimes around the world presently fall into two categories. "First to file" regimes offer patent protection to the first inventor to file a patent application.
