Knowledge of a Complaint May Be Insufficient to Support Claims of Indirect Infringement and Willfulness

In that case, the plaintiff sought damages for post-suit indirect infringement and willfulness for the first time in its second amended complaint, alleging that the defendant possessed knowledge of the patent “since at least the filing” of the original complaint. The defendant moved to dismiss, arguing that the plaintiff could not rely on the original complaint to establish knowledge of the patent.

In granting the defendant’s motion to dismiss, the district court first pointed out that there is no binding authority on the question of whether a defendant must have the knowledge necessary to satisfy a claim for indirect infringement or willfulness before a lawsuit is filed. District courts across the country have disagreed on the issue, including different judges within the District of Delaware, and neither the Supreme Court nor the Federal Circuit have ruled on the issue. Against that backdrop, the district court reasoned that no other area of tort law permits a plaintiff to establish an element of a legal claim simply with evidence it filed a complaint.

Thus, the district court held that the plaintiff’s complaint failed to state a claim for indirect or willful infringement where the defendant’s alleged knowledge of the asserted patents is based solely on the filing of a prior version of the complaint in the same lawsuit. The district court explained that “[i]t seems to me neither wise nor consistent with the principles of judicial economy to allow court dockets to serve as notice boards for future legal claims.” And with respect to enhanced damages under 35 U.S.C. § 284, that remedy is punitive and should be reserved for extraordinary cases. Enhanced damages do not exist to provide an incentive to sue innocent actors who have no knowledge of the patent. Finally, the court stressed the efficiency gained when a plaintiff provides a pre-suit notice letter, allowing the parties to potentially avoid an expensive patent infringement lawsuit.

Notwithstanding its decision here, the district court explained that pleadings that allege other facts from which it is plausible to infer that defendants had sufficient pre-suit knowledge may adequately plead such claims because, in those instances, the knowledge is not based solely on the filing of a complaint. Similarly, the district court noted that its decision does not prevent a plaintiff from filing a second lawsuit alleging that a defendant had the requisite knowledge based on the defendant's awareness of the first lawsuit.

Practice tip: To the extent possible, a plaintiff should include in its complaint all factual allegations that show or support an inference that the defendant knew of potential infringement of the asserted patent(s) prior to suit. If such facts do not exist, a potential plaintiff should consider whether a pre-suit notice letter might bolster its allegations of indirect or willful infringement.

The Federal Circuit recently vacated a decision by the Patent Trial and Appeal Board after concluding that the board’s analysis of licensing evidence offered as a secondary consideration of nonobviousness constituted legal error and was not supported by substantial evidence. According to the court, the board applied a more exacting and improperly heightened nexus standard than is required by law for license evidence.

In a recent decision designated as Informative, the USPTO Director determined that the Patent Trial and Appeal Board abused its discretion by instituting two inter partes review proceedings challenging the same patent, based on petitions advancing different constructions of the same claim term. The Director expressed concerns that permitting multiple petitions based on alternative claim constructions effectively circumvents word count limitations, strains board resources, and undermines procedural efficiency.

Earlier this year, the Federal Circuit’s decision in Qualcomm Inc. v. Apple Inc. (Qualcomm II) raised questions about the extent to which petitioners can rely on applicant admitted prior art (“AAPA”) in inter partes review proceedings.  The Federal Circuit’s recent decision in Shockwave Medical, Inc. v. Cardiovascular Sys., Inc. largely cabins the Qualcomm II decision to its particular facts and makes clear that AAPA can be used as evidence of background knowledge as part of an obviousness argument.

The Federal Circuit recently reversed a PTAB determination on remand that a patent was obvious over applicant admitted prior art (“AAPA”) in combination with prior art patents, holding that expressly designating AAPA as a “basis” for a ground is improper under 35 U.S.C. § 311(b). In doing so, the Court rejected the PTAB’s “blanket rule” that “AAPA used in combination with prior art patents or printed publications under § 311(b) is ipso facto not the basis or part of the basis of a ground.” Ultimately, while the case clarifies that expressly listing AAPA in an IPR ground is improper, the precise line between proper and improper uses of AAPA in other instances remains unclear.

The Northern District of Ohio denied a motion to compel the plaintiff to produce test results referenced in its initial disclosures and complaint. The court found that because the “test results are not facts but rather are opinions,” the information was protected as work product. Furthermore, because that testing would not be used as evidence in the litigation, the defendant was not prejudiced.
