Post-grant patent proceedings provide a critical mechanism for disputing the validity of a patent once it has been issued by the United States Patent and Trademark Office (USPTO). This vital process helps guarantee that all patents meet rigorous standards for novelty and non-obviousness, benefiting both businesses and individuals. To gain a deeper understanding of these proceedings and their potential implications for you, consider consulting with an experienced Orange County, California Patent Lawyer.

Why Do Post-Grant Proceedings Matter?

Post-grant proceedings at the USPTO allow competitors and other parties to challenge the validity of an issued patent. For California-based inventors, startups, and businesses, a clear understanding of these administrative reviews is essential for both safeguarding intellectual property and effectively addressing potential challenges to their patents.

Post-grant proceedings, conducted by the USPTO’s Patent Trial and Appeal Board (PTAB), involve a legal review to determine whether a granted patent should be modified or invalidated. Established by the America Invents Act (AIA) of 2011, this process aims to streamline patent disputes and reduce the burden of costly federal court litigation. It is a necessary step to ensure that patents meet all legal validity requirements. The following post-patent proceedings are available:

  • Inter Partes Review (IPR): These proceedings allow third parties to challenge the patentability of claims in an already issued patent based on a limited set of prior art.
  • Post-Grant Review (PGR): These proceedings offer a broader scope for challenging patentability compared to IPR, including prior art, lack of written description, and ineligible subject matter. It must be filed within nine months of a patent being granted.
  • Covered Business Method (CBM) Review: These proceedings apply only to covered business method patents, addressing companies accused of infringement.

Who is Eligible to File a Post-Grant Patent Challenge?

Understanding your rights and limitations regarding patent challenges is crucial, whether you have recently secured a patent or are considering disputing a competitor’s. Both scenarios require familiarity with federal eligibility rules and filing restrictions.

Generally, any third party, other than the patent owner, can start specific post-grant proceedings. The most frequently used proceedings are IPR and PGR. The petitioner must not have previously filed a civil lawsuit to challenge the patent’s validity. Additionally, the petition must be filed no later than nine months after the patent was granted. It should be noted that if a petitioner is found to be estopped from contesting the patent on the grounds in the petition, they are prohibited from filing a PGR.
