On September 16, 2011, President Obama signed the America Invents Act.

On March 16, 2013, the third and final wave of provisions of the America Invents Act (AIA) became effective.  This completes the overhaul of the U.S. patent law that began with the enactment of the AIA on September 16, 2011.  The United States will move to a first-to-file system with these provisions.  It will greatly expand the definition of prior art and usher in the use of post grant review.



Beginning in mid-March, the United States Patent Office (Patent Office) will use a first-to-file system rather than the first-to-invent system that is currently in place. This means inventors will no longer be able to “swear behind” the date that they first conceived of their invention. Rather, priority will be determined by the patent application’s effective filing date — the date the application was filed or the filing date of the earliest application for which the application can claim priority. As a result, once the AIA takes full effect on March 16, 2013, speed to the Patent Office will be paramount, and clients will likely need to file patent applications earlier and may need to file follow-on applications more often than their current procedures require.

One way to avoid the AIA is to claim priority to an application filed before March 16. Non-provisional applications filed on or after March 16 will remain under current law if they claim priority to an application that was filed before March 16 and contain the same material as that prior application. If the non-provisional application filed on or after March 16 includes new material, it will be subject to the AIA and its first-to-file system, expanded prior art provisions and other procedures.

For private venture-backed companies, this will mean that they may need to spend money on patents, the patent process and the development of patent strategies earlier and more often than what is typical in the first-to-invent system.

Expansion of Available Prior Art

Under the AIA, prior art is defined as any invention that was patented, described in a printed publication, in public use or on sale or otherwise available to the public before the effective filing date of the patent application. There are no geographic requirements for prior art, thus, for applications filed on or after March 16, prior art can come from anywhere in the world and be in any language. Even more expansive is the catch-all phrase “otherwise available to the public,” which inserts a great deal of uncertainty as to how it will be interpreted.

There is a very narrow exception for disclosures that are made within one year of the effective filing date by the inventor or an individual who derived his/her invention from the inventor’s disclosure. However, this exception should not be relied upon due to, for example, the uncertainty surrounding interpretation of “derive” and the difficulty one is likely to encounter when trying to prove derivation.

Post Grant Review

Anyone who has not first initiated a civil action will be able to challenge a patent filed after March 16 through post-grant review. In order for review to be granted, the petitioner must request review within nine months after the patent is granted and demonstrate that it is more likely than not that one of the patent’s claims is unpatentable.

The combination of the expansion of available prior art and post-grant review means that obtaining a patent for an application filed on or after March 16 will likely be much more difficult than under current law. On the other hand, petitioners will be estopped from bringing a civil action or proceeding in the Patent Office on any ground that was raised or reasonably could have been raised during the postgrant review.

Takeaways and Recommendations

  • Avoid the expanded prior art provisions and the uncertainty of the new AIA procedures by ensuring that the company’s patent is subject to the current first-to-invent rules.
    • For inventions that have early invention dates, file patents before March 16.
  • Prioritize applications that have conception dates prior to September 16, 2012 (the date the first wave of AIA provisions became effective).
    • Consider providing as much detail as possible in any provisional applications that the company intends to file before March 16.
    • Before March 16, file applications that add new material to previously filed applications.
    • For child applications filed on or after March 16, consider filing two applications, with one application containing the most well-supported claims, in order to maximize the company’s ability to maintain pre-March 16 priority.
  • Consider revising internal policies and procedures to account for the new prior art provisions.
    • Evaluate the company’s policies regarding prior approval of public disclosures to ensure that the company will not need to rely on the one-year exception. This includes policies regarding publications, conferences, press releases and social media. If the company does not currently have such policies, consider putting them in place.
    • Evaluate the company’s procedures for developing and patenting new technology. Updated timelines may be necessary to enable the company to be the first to file. Consider filing follow-on provisional applications for all important developments in order to secure earlier effective filing dates.
