Inter Partes Review (IPR)

Navigating the world of patent law requires an understanding of many complex processes. One such example is the Inter Partes Review (IPR) proceeding.

This administrative proceeding is an alternative to traditional patent litigation. An IPR is often faster and less expensive than traditional patent litigation, making it a significant tool in patent disputes. Understanding the IPR timeline is crucial. From petition to final written decision, an IPR will typically conclude within 12 to 18 months.

Whether you're an inventor, patent holder, or simply interested in patent law, this guide will provide valuable insights into the IPR process.

What is Inter Partes Review (IPR)?

Inter Partes Review (IPR) is a procedure used to challenge the validity of patent claims. It allows third parties to review the patentability of one or more claims post-grant.

Started in 2012 by the America Invents Act, IPR was introduced to streamline patent disputes. It aims to make patent challenges more efficient and less costly.

The process takes place at the Patent Trial and Appeal Board (PTAB). The PTAB consists of administrative patent judges skilled in both patent law and related technologies.

Inter Partes Review Process

Here's how the process generally works:

  • Petition Filing: Any third party, except the patent owner, can file a petition to initiate an IPR.
  • Preliminary Response: The patent owner may respond to the petition to present arguments why the IPR should not proceed.
  • Institution Decision: The PTAB decides whether to proceed with the review.
  • Trial and Hearing: Both parties present their arguments.
  • Final Decision: Within one year of the decision to institute an IPR, the PTAB is statutorily required to issue a final decision.

An IPR provides a streamlined approach to addressing a key issue in many patent disputes, namely validity of an issued patent. Determining the validity of claims in a patent through the IPR process can go a long way in resolving a potential conflict without the expense of addressing all other issues that may be raised during patent litigation.

Significance in Patent Litigation

Inter Partes Review (IPR) plays a crucial role in patent and IP litigation. An IPR offers an alternative avenue for resolving patent disputes outside of traditional court settings.

An IPR tends to be faster and cheaper than going to court. The IPR aims to resolve disputes more efficiently, offering a streamlined process.

For businesses, the process can be strategically significant. Uncertainty posed by questionable patents can be resolved without engaging in prolonged litigation.

The decision to proceed with an IPR can significantly influence litigation strategy. Companies often use an IPR to challenge competitors' patents after being served with a Complaint.  An IPR may be an effective tool to invalidate patent claims asserted against a defendant.  However, an IPR also raises estoppel issues that may prevent a defendant from subsequently asserting certain defenses during litigation should the IPR be unsuccessful in invalidating the challenged claims.

The availability of an IPR has reshaped the landscape of patent litigation. An IPR provides a valuable tool for challenging the validity of a patent.  However, the potential estoppel issues must be weighed with other patent litigation strategies.

  • 1 Filing the petition.
  • 2 Preliminary response by the patent owner.
  • 3 Institution decision by PTAB.
  • 4 Discovery and oral hearings.
  • 5 Final written decision by PTAB.

Initiating an IPR: Requirements and Procedures

Starting an Inter Partes Review (IPR) involves several key steps. Understanding these steps is important when deciding whether to proceed with an IPR.

  • 1 Any third party (someone other than the patent owner) can file a petition to initiate an IPR. The petitioner must wait to file the petition until the later of (i) nine months after a patent grant, or (ii) after any post-grant review has terminated.
  • 2 The petitioner must identify all claims to be challenged and all grounds on which each claim to be challenged is based.
  • 3 The petitioner may only challenge claims as being anticipated by or obvious in view of prior patents or printed publications.
  • 4 The petitioner must demonstrate a reasonable likelihood of success on at least one challenged claim.
  • 5 The patent owner can file a preliminary response to the petition to institute the IPR. This response is crucial, as it counters the petitioner's arguments.
  • 6 Once both the petition and response are reviewed, the PTAB decides whether to institute the IPR. This decision is final and non-appealable.

The Role of the Patent Trial and Appeal Board (PTAB)

The Patent Trial and Appeal Board (PTAB) is an administrative tribunal which handles IPR proceedings.  The PTAB is composed of the USPTO Director, Deputy Director, Commissioner for Patents, Commissioner for Trademarks, and Administrative Patent Judges.  The Administrative Patent Judges have expertise in technology and patent law and are the primary officiants of IPR proceedings

The PTAB first determines whether to institute an IPR after a thorough evaluation of the third party petition and patent owner’s response.  Upon instituting an IPR, the PTAB oversees the schedule and manages the IPR through the final decision.  

Appeals and Settlements

The final decision of an IPR, as rendered by the PTAB, can be appealed. An appeal is brought before the United States Court of Appeals for the Federal Circuit to permit judicial review of the PTAB's decision.

Parties in an IPR proceeding may reach a settlement prior to a final decision.    The parties must submit a motion to terminate the IPR proceedings.  While such a motion will typically terminate the proceedings, granting the motion is at the discretion of the PTAB and the PTAB may still proceed to issue a final decision.
