Melanie K. Sharp — patent litigation summary

Focus and technology areas. Sharp is a Wilmington, Delaware trial lawyer whose stated practice focus is intellectual property litigation, particularly patent litigation, plus complex commercial litigation in state and federal courts (Young Conaway firm bio; Colorado Bar CLE faculty bio). Her docketed patent work is broad rather than concentrated in one technology: pharmaceutical and biologic disputes (Regeneron Pharmaceuticals v. Amgen; Pharmacyclics/Janssen v. Alvogen/Natco; the Human Genome Sciences v. Amgen § 146 interference appeal), medical devices (Sight Sciences v. Ivantis/Alcon), semiconductor processing equipment (MKS Instruments v. Advanced Energy), multimedia networking software (nCUBE/ARRIS v. SeaChange), and most recently cashless-payment hardware for commercial laundry machines (Alliance Laundry Systems v. PayRange). Firm materials also describe her as experienced in "high-stakes pharmaceutical and biotechnology disputes."

Side preference. She is essentially a two-sided litigator and, more specifically, a Delaware local-counsel specialist. The tracked data show one appearance — Alliance Laundry Systems, LLC v. PayRange Inc., for the plaintiff, as local counsel — but that single data point reflects docket coverage, not a plaintiff-side orientation. Search results show her representing patentees/accused-infringer plaintiffs (MKS, Sight Sciences, nCUBE/ARRIS) and accused infringers (SeaChange, Amgen, Alvogen/Natco) with roughly equal frequency, usually as Delaware counsel alongside out-of-state lead firms such as Gibson Dunn, Proskauer Rose, Cooley, Kirkland & Ellis, and Honigman.

Firm context. She has been at Young Conaway Stargatt & Taylor, LLP in Wilmington since entering private practice in 1987, and serves as Chair of the firm's Commercial Litigation Section (per firm event and CLE materials; the firm bio page lists her as a partner). No prior law firm affiliations were found. Her only pre-firm role was a clerkship.

Notable matters and outcomes. Two verifiable results stand out: a $4.2 million plaintiff's verdict for MKS Instruments against Advanced Energy (D. Del. 2002), and D. Del. 2012 contempt proceedings in nCUBE/ARRIS v. SeaChange, where Judge Stark denied the patentee's motion to hold her client SeaChange in contempt — a client-favorable ruling (TiVo "colorable differences" analysis). More recently she has been Delaware counsel to Amgen in Regeneron Pharmaceuticals v. Amgen (BPCIA biosimilar litigation) and to Alliance Laundry Systems in the ongoing PayRange dispute, where PayRange has counterclaimed on a portfolio of mobile-payment patents and Alliance moved to dismiss several asserted claims as ineligible under § 101. The PayRange district-court action has spawned related PTAB proceedings, an antitrust/false-advertising suit in the Western District of Wisconsin, and a 2026 Delaware complaint in which Alliance is the defendant; results in those matters are not yet resolved in sources reviewed.

PTAB / IPR experience. No IPR or PGR filings, petitions, or papers listing Sharp as counsel were located; the PTAB briefs in the PayRange proceedings list Honigman (for Alliance) and Arnold & Porter (for PayRange) as counsel of record. Her PTAB-adjacent work appears to be indirect, through the parallel district-court litigation and her prior Board interference/§ 146 appeal work in Human Genome Sciences v. Amgen.

Bar and education. J.D., Temple University Beasley School of Law (1986); B.A., University of Delaware; admitted to the Delaware bar in 1986, and to the U.S. District Court for the District of Delaware and the U.S. Court of Appeals for the Third Circuit (one CLE bio additionally lists Federal Circuit admission; the firm website does not, so that item is not fully corroborated). Law clerk to Chancellor William T. Allen, Delaware Court of Chancery, before joining Young Conaway in 1987.
