Biography Press Room

Steven Kayman is a partner in Proskauer's Litigation Department. He focuses on intellectual property litigation but, in his 30-plus years of practice — all with Proskauer — he also has had extensive experience litigating disputes involving securities, bankruptcies and workouts, real estate, employment, contracts and many other commercial matters.

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

Steve has particular experience and command in matters involving the movement of employees between competitors, the appropriation of trade secrets, employee raiding and liftouts, and agreements containing non-competes and other restrictive covenants.

Clients have called on him 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 confidential information, other intellectual property, 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 and was recently appointed as an Adjunct Professor of Law at Brooklyn Law School, where he will be teaching a workshop on trade secrets.

Steve’s deep experience in litigating trade secret and intellectual property cases includes 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 and devices

  • All-season automobile tires

Steve has practiced before federal and state courts in New York and other jurisdictions, doing both trial and appellate work. He also has extensive experience with alternative dispute resolution, including practice before the AAA, JAMS, the SEC, the ITC, the NYSE, the NASD, mediators and “rent-a-judges.”
