Realtek Semiconductor Corp. is seeking nearly $1.5 million in legal fees and costs following its defense against a patent infringement lawsuit in the U.S. District Court for the Western District of Texas. This request comes after the Federal Circuit recognized Realtek as the prevailing party in the case.
The litigation began when Future Link Systems, LLC filed two patent infringement suits against Realtek, alleging that the company’s integrated circuit products infringed on several patents. During the proceedings, it was revealed that Future Link had a licensing agreement with MediaTek, a competitor of Realtek. This agreement stipulated that MediaTek would pay Future Link a lump sum if Future Link initiated a lawsuit against Realtek. Shortly after this disclosure, Future Link voluntarily dismissed both cases without prejudice.
Realtek subsequently sought attorney’s fees under 35 U.S.C. § 285, costs under Federal Rule of Civil Procedure 54(d)(1), and additional sanctions. The district court denied most of these requests, determining that Realtek was not a prevailing party. However, the Federal Circuit vacated this decision, holding that Realtek was indeed a prevailing party. The court emphasized that a dismissal with prejudice constitutes a judicially sanctioned change in the parties’ legal relationship, effectively barring Future Link from asserting the same patents against Realtek’s products in the future. The case was remanded to the district court to determine whether the case is “exceptional” under § 285 and whether fees are warranted.
This development underscores the importance of the prevailing party designation in patent litigation, as it can significantly impact the awarding of attorney’s fees and costs. The Federal Circuit’s decision clarifies that a defendant can be considered a prevailing party even when a case is dismissed with prejudice, provided that the dismissal materially alters the legal relationship between the parties.
