Experience
- Obtained an injunction against a client's former executive and his competing business enjoining them from competing in the marketplace and utilizing the client's confidential information and trade secrets. Ultimately favorably settled the matter with a permanent injunction and significant damage award.
- Defeated a motion for a temporary restraining order and preliminary injunction brought by a competitor after our client hired two salespeople terminated by the competitor. After defeating the claims for injunctive relief, successfully moved to dismiss the complaint based upon and overbroad and unenforceable restrictive covenant.
- Served as lead counsel for a Fortune 500 technology company in a false advertising and trade dress infringement case, convincing the court to force the client’s competitor to change both its advertising and the shape and color of its product.
- Successfully defended and obtained summary judgment on behalf of a Fortune 500 technology company in a multimillion-dollar breach of contract case.
