MoloLamken

MoloLamken LLP is a national litigation boutique known for handling high-stakes, complex disputes. The firm has offices in New York, Washington, D.C., and Chicago. While not an AmLaw-ranked firm due to its focused size, Chambers and Partners recognizes it as a leading firm, particularly for its appellate practice. According to a 2025 firm profile, MoloLamken consists of approximately 21 partners and 21 other lawyers. The firm operates as a specialized advocate in trials and appeals, representing both plaintiffs and defendants in civil, criminal, and regulatory matters.

The firm’s intellectual property practice has a strong focus on appellate litigation, particularly before the U.S. Court of Appeals for the Federal Circuit. MoloLamken handles patent disputes across a range of technologies, including life sciences, cellular communications, software, and semiconductors. The firm's patent litigators represent clients in matters before federal trial courts, the International Trade Commission, and the U.S. Supreme Court. Based on public case information and client lists, the firm represents both patent holders and accused infringers, indicating a balanced practice that does not exclusively favor either plaintiffs or defendants.

The firm's only tracked appearance in the provided data was as lead appellate counsel for the plaintiff in Multimedia Technologies Pte Ltd v. LG Electronics Inc. That case was an appeal from the Patent Trial and Appeal Board (PTAB) that was ultimately dismissed by agreement of the parties in January 2026. Public sources show other significant patent matters, including securing a Federal Circuit affirmance of a $440 million patent infringement judgment for VirnetX against Apple. The firm also has an active PTAB practice, representing clients in inter partes review (IPR) proceedings and subsequent appeals; it secured a victory for DivX against Netflix at the PTAB and won a Federal Circuit appeal for Merck vacating a PTAB decision.

The patent litigation practice is co-chaired by Jeffrey A. Lamken, Michael Pattillo, and Ben Quarmby. Lamken, a founding partner of the firm, is a nationally recognized appellate advocate frequently appearing before the Federal Circuit and the U.S. Supreme Court. Other key partners in the IP practice group noted for their experience include Lucas Walker and Rayiner Hashem, who specialize in appellate litigation and technology cases, respectively.
