Joseph J. Farnan: Untimely Terminal Disclaimer Still Admissible


We recently reported on an invalidity decision by District Judge Joseph J. Farnan Jr. that declined to give effect to a so-called terminal disclaimer. Earlier this week, the Court followed that post-trial opinion with a decision resolving the parties’ evidentiary disputes. Among those disputes? The admissibility of the same disclaimer.

In its opinion, the Court noted that plaintiffs sought to introduce the disclaimer after the close of evidence. Although it acknowledged “concern” over the timeliness of the filing, the Court nonetheless allowed the document into evidence. As part of the patent-in-suit’s prosecution history, the disclaimer became on filing an “admissible supplementation of an already identified trial exhibit.”

As a result, the Court concluded, the “issue of timeliness is more appropriately addressed in the context of the disclaimer’s effectiveness, rather than its admissibility.”
