Understanding the America Invents Act: Strict Novelty Provisions and Post-Grant Review
Strict Novelty Provisions and Post-Grant Review
The America Invents Act (AIA), passed in 2011, brought
significant changes to the U.S. patent system, including modifications to the
novelty provisions and the introduction of new post-grant review mechanisms.
The impact of these changes cannot be overstated, as they have reshaped patent
practices and litigation in the United States, making it crucial for patent
applicants and holders to understand the law's nuances.
The Core of Novelty: What Changed Under the AIA?
Under the pre-AIA system, the U.S. followed a
"first-to-invent" system, where inventors who could prove they were
the first to conceive and reduce to practice an invention were granted the
patent. However, the AIA shifted the system to a "first-to-file"
approach, aligning the U.S. with the rest of the world’s patent systems.
Novelty Under the AIA
The AIA introduced stricter rules for novelty, and today, an
inventor must file a patent application before anyone else does to secure their
rights. The novelty requirement, which ensures that an invention is new and not
previously disclosed, is one of the most critical aspects of patent law. The
novelty provision under Section 102 of the AIA now states that an invention
cannot be patented if it has been disclosed in prior art before the filing date
of the patent application.
What does this mean? For instance, if a piece of prior
art—such as a previously published patent or public disclosure—has already made
the invention known, then the new invention lacks novelty and cannot be
patented. The prior art is not only limited to patents but can also include
printed publications, public use, or sales activity.
However, the AIA also introduced exceptions to this novelty
rule. For example, if the inventor discloses their invention to the public,
they may have a one-year grace period before filing a patent application. This
grace period allows inventors some breathing room to publicly share their ideas
(for academic, marketing, or funding purposes) without immediately losing their
novelty rights.
Strict Novelty Provisions: The Challenges for Inventors
The shift to a "first-to-file" system means that
applicants are under more pressure to file early. The strict novelty provisions
make it more critical than ever for inventors to file their patents quickly.
Here are the challenges:
Global Competition: With the rise of international patent
filings, especially under the Patent Cooperation Treaty (PCT), inventors face
increased competition in securing patent rights. A public disclosure in one
country could affect patentability in other jurisdictions.
Early Disclosure: Disclosing an invention before filing the
patent application can risk its novelty. This is a significant concern for
startups and independent inventors who may not have the resources to file
patents immediately but want to showcase their innovations to potential
investors or partners.
Prior Art Search: The necessity for a thorough prior art
search has never been more critical. Patent applicants must ensure that no
public disclosure of their invention exists prior to their filing, as even a
single publication could jeopardize their patent rights.
Post-Grant Review (PGR): A New Avenue for Challenging
Patents
The AIA also introduced mechanisms such as Post-Grant Review
(PGR) and Inter Partes Review (IPR) to improve patent quality by allowing third
parties to challenge granted patents. PGR provides a way for a third party to
challenge the validity of a patent within nine months of issuance, focusing on
issues like novelty, obviousness, written description, and enablement.
Benefits of Post-Grant Review
Early Challenge: The ability to challenge a patent early in
its life cycle provides an opportunity to invalidate patents that should not
have been granted in the first place. This helps ensure that only valid patents
remain in force, which is essential for a healthy and competitive market.
Flexibility in Grounds for Challenge: Unlike IPR, which is
primarily limited to challenges based on patents and printed publications, PGR
allows challenges based on a broader set of criteria, including novelty and
written description requirements.
Cost and Time-Effective: For businesses concerned about
patent infringement or patent trolling, PGR provides a relatively low-cost and
time-efficient alternative to full-fledged litigation.
Conclusion: A New Era of Patent Protection
The America Invents Act has drastically altered the
landscape of U.S. patent law. The transition to a "first-to-file"
system and the strict novelty provisions mean that inventors need to be
proactive in filing patents early to protect their innovations. At the same
time, the introduction of post-grant review mechanisms gives third parties the
ability to challenge potentially invalid patents, improving overall patent
quality and protecting against the proliferation of weak patents.
For inventors, companies, and legal professionals,
understanding these changes is essential for navigating the modern patent
system effectively. Being proactive in patent filing, conducting thorough prior
art searches, and being aware of post-grant review options can make a
significant difference in protecting intellectual property and securing
competitive advantages in the marketplace.
