Many of the world's leading pharmaceutical, biotech, medical device, technology, financial services, staffing, and insurance companies look to Erik for thoughtful and practical advice concerning how best to protect their trade secrets and customer relationships from misappropriation by former employees, ex-business partners, competitors, and hostile actors in the United States and abroad, and to avoid liability when hiring from competitors. When necessary, clients rely on Erik for aggressive representation in litigation, where he has won substantial victories in court and at the negotiating table, including broad-reaching injunctive relief and multimillion-dollar payouts, in trade secret misappropriation, unfair competition, and breach of restrictive covenant cases.
