Jeremy Plenzler

Many patent attorneys argue before the Patent Trial and Appeal Board. Jeremy Plenzler spent twelve years deciding cases there.

As an Administrative Patent Judge at the PTAB from the inception of the America Invents Act through 2025, Jeremy presided over hundreds of AIA trials, inter partes reviews, post-grant reviews, and covered business method proceedings, and ruled on thousands of ex parte appeals, including appeals from reexamination proceedings. He didn’t observe PTAB practice from the outside. He experienced it from the bench.

That experience gives VHIP’s clients something no amount of outside experience can replicate: insight into how patent judges think. Jeremy knows what makes a petition persuasive, which arguments land and which fall flat, how panels evaluate claim construction disputes, and where institution decisions turn on factors practitioners rarely see. When he prepares a client’s PTAB strategy, whether defending a patent under challenge or mounting an offensive invalidity campaign, he brings the perspective of someone who has sat on the other side of the decision.

Jeremy’s practice extends well beyond PTAB proceedings. Before joining the Board, he spent nearly a decade in private practice obtaining hundreds of patents for clients across software, electronics, mechanical systems, and complex electromechanical technologies. He brings that prosecution foundation to his current work in patentability and validity analysis, freedom-to-operate counseling, and strategic portfolio assessment. Clients get a practitioner who understands both how to build patents and how they hold up under challenge.

Before law, Jeremy spent five years as an engineer focused on modeling complex systems, experience that sharpens his ability to digest technical inventions quickly and communicate with inventors in their own language. He evaluates patent rights with the precision of an engineer and the judgment of a jurist.
