Steve Kayman is a New York-based Partner in the Litigation Department. Steve is best known as an intellectual property litigator but, in his thirty years of legal practice, all with Proskauer, he has also had extensive experience litigating disputes involving securities, bankruptcy and work-outs, real estate, employment and many other commercial matters.

Steve founded Proskauer’s Non-Compete and Trade Secrets Practice Group and has served as a head of the group for many years. Steve also chaired Proskauer’s firmwide Technology Committee, with oversight responsibility for all of Proskauer’s information services, technology, knowledge management and practice support operations.

Steve assists clients in both litigated and non-litigated matters involving the movement of employees between competitors, the appropriation of trade secrets, employee “raiding” and “lift outs,” and the drafting and negotiation of employment and other agreements containing restrictive covenants. Clients have called on Steve when their employees have “jumped ship” to a competitor, when hiring a competitor's employees, and to craft agreements, policies and procedures aimed at protecting the client's intellectual property, confidential information and relationships with its customer base and workforce. Steve has litigated for and counseled clients in thousands of disputed matters in these areas, including major banks and insurance companies, other financial institutions, leading consulting firms, and media and entertainment companies. He also has written and lectured extensively about trade secrets and non-competes.

Steve’s deep experience litigating trade secret and intellectual property cases has included disputes involving such disparate technologies as:

  • Smartphones 
  • Microphones used in electronic devices

  • Bomb detection machines for airports

  • Commercial skipping software for video players
  • Computer network security software
  • Day trading software
  • Smart cards and proximity cards
  • Wind and solar power generation
  • Teeth whitening products 
  • Cosmetics products 
  • All-season car tires

Apart from the intellectual property arena, Steve considers himself to be a general commercial litigator qualified to assist clients in almost any kind of business-related dispute. He has practiced extensively before federal and state courts in New York and other jurisdictions, doing both trial and appellate work. Steve also has substantial experience with alternative dispute resolution, including practice before the AAA, the SEC, the NYSE, the NASD, mediators and “rent-a-judges.”
