John Sganga

An experienced and proven advocate and trial lawyer, John Sganga has spent over three decades successfully and exclusively litigating intellectual property and technology disputes. John’s cases always involve a client whose technology or brand has been stolen or high-jacked, or who has been wrongly accused of doing so.

A quick study in understanding even the most pioneering innovation, John is able to distill complex technologies to their core while gaining an in depth understanding of his client’s business model and financial imperatives. John’s skills as an effective communicator and persuasive negotiator enable him to thrive in high pressure situations and high-stakes cases. He is regarded as someone who remains calm while out-thinking and out-persuading his opponents.

John is personally dedicated to working diligently to define a win for his client at the onset of every matter, developing a distinct approach to problem-solving and leading his team in executing the right strategy appropriately and energetically to victory. Having represented plaintiffs and defendants alike, John has secured courtroom victories of over $100 million for both plaintiffs and defendants in high-stakes technology disputes. He appears in courts nationwide, including jury trials, bench trials, arbitrations, appeals and administrative proceedings before the Patent Trial and Appeal Board (PTAB), Trademark Trial and Appeal Board (TTAB) and the International Trade Commission (ITC). 

John’s experience includes patent, trade secret, copyright and trademark infringement matters, as well as contract disputes involving technology development and IP rights. The industries with which John is familiar are also diverse and range from medical and dental devices, engine technology and software, to food and beverage and consumer products.

John has been active as a bar leader, is a past chair of his firm’s Litigation practice, a frequent lecturer on IP law and litigation strategy, an author of a book and numerous articles, and has taught patent litigation as an adjunct law professor. He has been recognized with numerous awards as a stand-out lawyer locally (Super Lawyers), state-wide (Daily Journal “Top IP Attorneys in California”), nationally (The Best Lawyers in America, BTI “Client Service All-Star” and Martindale Hubbell AV judicial pre-eminent rating), and internationally (IAM “World’s Leading Patent Professionals”).
