William L. Mentlik
New Jersey & Los Angeles, CA
After a career as an IP trial and appellate practitioner spanning five decades, William “Bill” Mentlik now focuses his practice on mediating complex IP disputes. Most notably, Bill has successfully mediated disputes involving domestic and international IP litigation and patent portfolio licensing, including SEP/FRAND disputes between large international technology companies.
Foretelling his success as a mediator, at the height of his career as a litigator, Bill was recognized in “BUSINESS NEWS NEW JERSEY” (now NJBIZ) as one of New Jersey’s top lawyer dealmakers. Although a battle-tested litigator, Bill’s priority is always to be the voice of reason, “get beyond everyone’s egos,” and find the most sensible outcome for any dispute. The perspective Bill brings to the cases he mediates is that of an IP litigator and businessman, whose charge is to find common ground between the parties, not to decide the case between them. A particular source of pride for Bill is the role he developed as a valued, long‑time member of the NJ Federal Bar, which prides itself on collegiality. He was the first lawyer from a dedicated IP boutique appointed to the Lawyers Advisory Committee to the Federal District Court in New Jersey, and he served on the subcommittee that drafted New Jersey’s local patent rules, which govern patent litigation in the district, and has served as a model for local patent rules in other district courts throughout the country.
Bill’s skills as a mediator also derives from his experience as an IP appellate practitioner, which required him to combine a thorough knowledge of the case record with a proven penchant for thinking on his feet. Early in his career, Bill successfully argued an appeal on behalf of laser pioneer Gordon Gould, which cleared the way for the issuance and vindication of four broad patents arising out of a 1959 patent application, certain of which dominated significant areas of basic laser technology into the 21st Century. Since that time, he has argued and/or briefed more than 30 appeals in numerous U.S. Courts of Appeal, most notably, the U.S. Court of Appeals for the Federal Circuit.
