Voluntary Nature of IPR Proceedings Forecloses Attorney’s Fees, According to District Court

Jun 14, 2022

In that case, the plaintiff sued the defendant for patent infringement based on defendant’s “automatic top-off” food fryers. The next month defendant presented plaintiff with several pieces of prior art that allegedly invalidated the claims. Defendant later filed an IPR petition alleging that each claim of the patent was anticipated by one of the references the defendant had previously identified. The board ultimately found all claims anticipated over that reference.

The district court dismissed the case and the defendant timely moved for attorney’s fees under § 285. According to the defendant, the plaintiff pursued frivolous litigation, including taking inconsistent positions before the court and the board, and proceeding with the litigation despite being presented with the invalidating art.

The plaintiff opposed the motion, arguing that Federal Circuit dicta and the statute’s silence on the matter show that attorney’s fees are not available for work in an IPR. The defendant countered, relying on a Federal Circuit case that addressed a unique situation in a reissue proceeding, and arguing that since the dispute was fully resolved through IPR, the IPR proceeding should be considered part of the patent infringement “case” for § 285 purposes.

The district court ultimately agreed with the plaintiff that § 285 attorney fees are not available for IPR proceedings. The court relied on both the words and context of the statute, as well as the Federal Circuit dicta that fees cannot be awarded for work completed during an IPR. IPR proceedings are voluntary, and the alleged infringer chooses to participate in the proceeding by filing a petition. As such, an alleged infringer is not entitled to receive attorney’s fees under § 285 for prevailing in an IPR proceeding.

Practice Tip: When seeking attorney’s fees, parties should consider focusing on an adversary’s conduct during litigation. Conduct during an inter partes review, even if it involves success based on a reference that has been presented to the patent owner, may not support a fee award because proceeding down the IPR route may be viewed as a voluntary choice outside of district court litigation.

In a recent final written decision, the PTAB determined that a reference patent was not prior art, despite the petitioner’s post‑filing attempt to correct its petition. While the petitioner argued that it intended to rely on the patent application’s earlier date of publication, both the corrected petition and the expert declaration continued to reference the issued patent rather than the published application.

In considering claims to a method of reducing cardiovascular events, the Federal Circuit held that the term a “clinically proven effective” amount did not render the claims patentable over the prior art. Specifically, the Federal Circuit held that the “clinically proven effective” amount, whether limiting or not, could not be used to distinguish the prior art because the claims also specified the exact amount of the drugs to be administered in the method. The Federal Circuit also rejected patentee’s evidence of unexpected results because that evidence was tied solely to the “clinically proven effective” limitation.

A magistrate judge in the District of Delaware issued a Report and Recommendation, that found the sole asserted claim was a “single means” claim and therefore invalid for lack of enablement. In reaching that conclusion, the magistrate judge rejected the patentee’s argument that the preamble of the claim disclosed a second element that satisfied the combination requirement of Section 112, paragraph 6 because the preamble simply recited a descriptor of the very apparatus that was the subject of the means-plus-function limitation in the body of the claim. The district court judge presiding over this case has scheduled a hearing to review the magistrate’s ruling.
