For seven years, he led Paul Hastings’ Intellectual Property Litigation practice as its Global Co-Chair. He serves as lead trial counsel for some of the most preeminent global technology companies in their most important matters.

His success has led him to be accepted as a Fellow of the Litigation Counsel of America and to be praised by numerous leading publications as one of the nation’s top intellectual property trial lawyers. Mr. Chaikovsky was Yahoo!’s first head patent counsel. Before practicing law, he was an engineer in the missile systems defense department of Hughes Aircraft Company.

Accolades and Recognitions

He has been recognized by IAM Patent 1000 as a “Talisman of the practice” “charismatic top-tier trial lawyer" and a “dynamite trial lawyer who never lacks for a convincing story to tell” and “when it comes to gutting a plaintiff’s damages theory, challenging validity on Section 101 grounds and drawing lines in the sand, he does it all brilliantly.” He is touted as a “swashbuckling lawyer capable of withstanding and fighting back against any onslaught and ultimately winning.” “He keeps himself up to date on everything and doesn’t just give you the textbook options when someone sues you.” He was singled out as a “trial attorney who scored big” and “demonstrated a track record of success” due to his trial preparation and presentation when The National Law Journal named him a "Winning Litigator." Benchmark Litigation also recognized Mr. Chaikovsky as a finalist for Intellectual Property Litigator of the Year and a National Litigation Star, while calling him “a hell of a lawyer and has some ‘buzzy star power’ about him.” Intellectual Asset Management notes that he “communicates exceptionally well and doesn’t let technical jargon dominate his arguments and thinking. He is a talented trial lawyer who deserves high recognition.” He is lauded by Chambers for being a “very sharp and detail-oriented litigator” with an “assertive, thorough and thoughtful approach” to litigation, in addition to having an “ability to adopt the viewpoint of in-house counsel” in order to best achieve client objectives. The National Law Journal also named Mr. Chaikovsky as one of its Intellectual Property Trailblazers where he was identified as being “a thought leader in patent litigation in the United States” due to “his innovative trial work protecting corporations using aggressive litigation strategies.”
