District Court Awards Post-Markman Attorneys’ Fees After Plaintiff Continued to Litigate Claims That Became Baseless in Light of the Court’s Markman Order

Plaintiff asserted 11 patents relating generally to methods of multimedia communications. The court found that eight of those patents claimed unpatentable subject matter and were invalid under 35 U.S.C. § 101. After claim construction the court granted defendant’s motions for summary judgment, finding that the defendant did not infringe one patent and that another was invalid under § 101. Plaintiff stipulated to noninfringement of the final remaining patent but reserved its right to appeal the claim construction issue. It later appealed.

The Federal Circuit affirmed the court’s summary judgment finding and all claim construction determinations but one. But because plaintiff had failed to articulate an infringement position under the affirmed claim constructions, the Federal Circuit had no choice but to remand the case. The parties eventually stipulated to dismissal and defendant moved for attorneys’ fees.

The court noted that an infringement case that is substantively weak when filed can become exceptional if claim construction renders the claims-at-issue baseless. Here, plaintiff’s case was initially weak—its claims relating to eight of the patents were dismissed because the patents were invalid under 35 U.S.C. § 101. But the case was not so extraordinarily weak as to be exceptional at inception. After the Markman order, however, plaintiff should have known that each remaining claim was baseless. Specifically, the court’s later invalidation of the claims of one patent was the “clear and necessary consequence of the claim construction.” And for the claims of the patent for which the court ultimately granted summary judgment of no infringement, plaintiff’s continued infringement theory directly contradicted the court’s Markman order. Instead of dismissing its claims based on these patents,  plaintiff “avoided summary judgment by stipulating to noninfringement, proceeded to appeal without a viable theory of infringement, and then prolonged the case by insisting on remand—caused by [its] own lack of clarity and specificity in the stipulation—without an infringement theory.” Continuing to litigate was, thus, objectively unreasonable and the case was exceptional. The court therefore awarded attorneys’ fees pursuant to 35 U.S.C. § 285.

Practice Tip: In order for a party to recover attorneys’ fees, a case need not be exceptional at inception. A party should re-evaluate whether any asserted claims or defenses become baseless after potentially case dispositive events like claim construction.

The Federal Circuit recently held that a patentee acted as its own lexicographer to define a claim term even though it did not explicitly define the term. Rather, because the patentee consistently and clearly used two terms interchangeably to describe the same structural feature and did so in all of the embodiments in which the feature appeared, the patentee impliedly gave the term its own, unique definition.

The Federal Circuit recently held an asserted patent was not entitled to its priority date because the priority application lacked written description support for the asserted claims. In so doing, the court explained that broad disclosures that do not provide reasonably specific support for narrower claims do not meet the written description requirement. The court also considered whether the inventor’s testimony showed they possessed the full scope of the claimed genus at the priority date or whether it was more likely the inventors first became aware of the claimed embodiments from public disclosures of the accused product.

The district of Delaware recently denied a defendant’s partial motion to dismiss pre-suit willful infringement from the litigation, finding instead that the allegations taken as a whole were sufficient to support pre-suit willfulness at the pleading stage. Specifically, the court found that the allegations as to the defendant’s involvement in a related foreign opposition proceeding and participation in the relevant industry were accompanied by detailed factual support that sufficiently pleaded willful infringement for the pre-suit period.
