The Comprehensive Guide to Inter Partes Review (IPR)
Inter Partes Review (IPR) is a vital mechanism in the U.S. patent system that allows third parties to challenge the validity of an already issued patent. Established under the America Invents Act of 2011, IPR proceedings are conducted by the Patent Trial and Appeal Board (PTAB) and offer a streamlined alternative to traditional litigation. This guide will provide an in-depth understanding of IPR, its processes, requirements, and implications for patent owners and challengers.
Comparison of Types and Applications of Inter Partes Review
| Type | Description | Eligibility | Common Applications |
|---|---|---|---|
| Standard IPR | A trial to determine the validity of a patent based on prior art. | Any third party not owning the patent. | Patent challenges in various industries, especially tech and pharmaceuticals. |
| Post-Grant Review | A broader review that includes eligibility challenges. | Any third party within 9 months of issuance. | Used for broader challenges, including patent eligibility. |
| Derivation Proceedings | Addresses allegations that a patent was derived from another’s invention. | Any party claiming derivation. | Used in disputes related to patent origination. |
| Reexamination | A process allowing for re-examination of a patent’s validity. | Patent owner or third party. | Used to clarify patent claims and resolve disputes. |
The IPR Process
What is Inter Partes Review?
Inter Partes Review is a procedure that allows a third party to challenge the validity of a U.S. patent. The review is conducted by the PTAB, focusing on whether the patent claims are novel and non-obvious as required under 35 U.S.C. §§ 102 and 103. The process typically starts with a petition filed by a challenger.
Filing an IPR Petition
To initiate an IPR, a petitioner must file a detailed petition that outlines their arguments for invalidating the patent. This petition must include:
- Identification of the patent being challenged.
- Grounds for the challenge based on prior art, including patents and printed publications.
- A thorough explanation of how the prior art supports the challenge.
Only parties that are not the patent owner can file for an IPR, ensuring that the system is available for those seeking to contest potentially invalid patents.
Eligibility Criteria
Under 35 U.S.C. 311, any person who is not the patent owner may file an IPR petition. However, strict eligibility criteria apply:
- A petitioner cannot have previously filed a civil action challenging the patent’s validity.
- If a party has been served with a patent infringement complaint, they must file an IPR within one year.
These restrictions ensure that the IPR process is not abused by parties who have already engaged in litigation.
Timeline of the IPR Process
The IPR process follows a structured timeline:
- Filing of the Petition: The petitioner submits their IPR petition to the PTAB.
- Institution Decision: Within three months, the PTAB decides whether to institute the review based on the petition’s merits.
- Trial Proceedings: If the review is instituted, the trial commences, typically lasting about 12 months.
- Final Written Decision: The PTAB issues a final written decision, determining whether the patent claims are valid or should be canceled.
This structured timeline offers a relatively quick resolution compared to traditional patent litigation, which can take years.
Advantages and Disadvantages of IPR
Advantages
- Cost-Effective: IPR can be significantly cheaper than traditional litigation.
- Faster Resolution: The streamlined process typically leads to quicker outcomes.
- Expert Review: The PTAB consists of judges with specialized knowledge in patent law.
Disadvantages
- Limited Discovery: The discovery process is more restricted than in courts.
- Potential for Abuse: Some argue that IPR can be used as a tool for harassment against patent owners.
- No Jury: Decisions are made by judges rather than a jury, which may not align with public sentiment.
