Mr. Canty is a founding member of Leydig’s Frankfurt office, which advocates for the intellectual property interests of European-based clients doing business in the United States. A focus of Mr. Canty’s practice is helping clients build U.S. patent portfolios by obtaining targeted and robust patent protection for their key technologies. He also advises clients on how to avoid liability from third party patents, performing freedom-to-operate investigations and finding solutions to potential infringement situations. For contentious matters, he implements and helps coordinate multi-jurisdictional strategies for achieving beneficial results.
Prior to becoming a lawyer, Mr. Canty studied engineering and worked in the automobile industry as an engineer and project manager. After later earning a law degree at Boston University, he began his legal career at a major New York IP law firm with a focus on patent litigation. He moved to Frankfurt in 1999 and has practiced there ever since.
