Spring 2013 (snippets)
On March 16, 2013, the final (and most significant) portion of the Leahy-Smith America Invents Act (AIA) took effect, and the United States broke from a first-to-invent regime to a first-inventor-to-file (FITF) regime. Of course, this break is far from clean as applications filed before March 16, 2013, as well as certain applications filed after March 15, 2013, will continue to enjoy the advantages of the old first-to-invent system. Since the AIA was enacted on September 16, 2011, the U.S. Patent and Trademark Office (USPTO) has played an important role in implementing the new patent law. In the eighteen months between the statute's enactment and the March 16 effective date, the USPTO published twelve notices of proposed rulemaking, issued a patent trial practice guide, and published a guidance document on the FITF provisions of the AIA, all of which culminated in the revision of the rules of practice in title 37 of the Code of Federal Regulations (C.F.R.). Set forth in this article are a few rule revisions that practitioners should pay careful attention to as we proceed into the FITF regime.
February 11, 2013 (snippets Alert)
The final phase of the America Invents Act (AIA) takes effect on March 16, 2013. This means that any patent application filed in the U.S. on or after that date, which, at any time during its pendency, contains a claim that is not fully supported in an application filed before March 16, 2013, will be subject to the new first-inventor-to-file rules under the AIA. As a result of this imminent change in U.S. patent law, it is recommended that companies consider several options.
