PTO Post-Issuance Proceedings

Properly navigating U.S. Patent and Trademark Office (PTO) post-issuance proceedings requires familiarity with these mechanisms and an understanding as to how they shape modern dispute strategy. Our Washington, D.C.-based attorneys have decades of experience across patent litigation and prosecution, giving us a deep perspective on post-grant tools. Since the America Invents Act, we have handled the post-issuance proceedings that were ushered in by that law, and have an even earlier history of examiner engagement and reexamination work. Our unified team blends litigation experience with deep post-issuance knowledge, allowing coordinated strategies when disputes move across multiple forums.

PV Law LLP, has earned numerous recognitions and rankings, reflecting the volume of proceedings we have handled and our record of successful outcomes. These achievements have been aided by our ability to meet the PTO’s evolving policies, standards, and expectations.  Among these are the requirement that parties harmonize their positions across parallel disputes, which makes coordinated representation, a hallmark of PV Law, more critical than ever.

How Do Inter Partes Reviews Fit Into A Modern Dispute Strategy?

One of the most widely used tools in the modern post-grant framework is inter partes reviews. These proceedings allow a party to challenge issued claims based on patents or printed publications, offering a focused mechanism for addressing anticipation and obviousness issues. Because they are limited to specific forms of prior art and governed by statutory timelines, they often run concurrently with district court litigation.

Our team has been involved in inter partes reviews since their creation, representing petitioners and patent owners across numerous technologies. This experience informs our assessment of institution prospects, estoppel implications and how positions adopted before the PTAB may influence related infringement or invalidity arguments in federal court.

Over the years, clients have benefited from our ability to conduct inter partes reviews to align with their broader goals, whether as a parallel forum for resolving validity issues or as part of a coordinated defense. The strategic value of these proceedings continues even  as the Office refines its standards for discretionary denials and imposes stricter requirements for consistency with parallel litigations.

What Role Does Ex Parte Reexamination Continue To Play?

Although newer procedures have become prominent, ex parte reexamination remains an important mechanism to challenge the validity of a patent. Our lawyers have been handling ex parte reexamination matters for many decades, long before the AIA.  This, coupled with our equally long history of handling prosecution matters, gives us insight into how examiners are likely to approach the asserted invalidity grounds. Ex parte reexamination can offer a different strategic profile than an IPR, particularly when a requester seeks to initiate a proceeding confidentially or seeks a lower-cost alternative to IPRs. Because these matters proceed directly before examiners rather than the Board, they provide unique opportunities for thoughtful, detailed technical engagement.

Our familiarity with the examination corps and robust experience with ex parte reexamination helps us advise clients as to whether this tool should be utilized in order to achieve their strategic objectives. Its continued availability means patent challengers can pursue targeted validity challenges and patent owners can pursue amendments in a proceeding outside of adversarial post-grant trials (e.g., IPRs).

Why Is Post-Grant Review A Significant Early-Stage Procedure?

Post-grant review offers one of the broadest opportunities for challenging the validity of a recently issued patent, including subject matter eligibility, written description, enablement and other issues beyond those available in IPRs. Because the window for filing post-grant review petitions is short, it plays a role primarily in disputes arising soon after close to a patent’s issuance.

In matters where the scope of available challenges is crucial, post-grant review may provide strategic advantages not found in other PTO post-issuance proceedings. When coordinated with district court litigation or licensing discussions, this tool can help shape the trajectory of a dispute at an early juncture.

How Does Supplemental Examination Support Patent Owners?

Patent owners may seek supplemental examination, a process designed to request the PTO’s review of information that may be relevant to patentability. This procedure can address potential issues before they arise in litigation, including inequitable-conduct allegations. Our attorneys can assist in evaluating the type of information that may warrant supplemental examination, guiding patent owners through the timing, scope and procedures of the process.

Because supplemental examination can lead to reexamination if the PTO identifies substantial new questions of patentability, our familiarity with both procedures allows us to help clients anticipate multistep paths within the post-issuance system. Patent owners often rely on this option to strengthen confidence in the enforceability of their patents before entering licensing, sale or litigation.

Why Does Cross-Forum Coordination Matter More Than Ever?

Today’s disputes frequently unfold across multiple venues, from the PTO to federal courts to the International Trade Commission. Our team coordinates each facet so positions taken in PTO post-issuance proceedings align with overarching objectives. This coordination is critical as the PTO increasingly scrutinizes inconsistencies between PTAB arguments and those advanced in other forums. Our structure supports unified strategy development, consistent technical narratives and careful management of estoppel implications.

Decades of experience in both administrative and judicial settings allow us to approach each post-grant tool with a clear view of how it affects, and is affected by, broader litigation.
