Marcus is an intellectual property lawyer who advises clients on a wide range of IP rights, with a focus on patent litigation.

Marcus has acted for clients in patent and regulatory disputes across the electronics, telecommunications, pharmaceutical and biotechnology sectors; including litigation before the High Court and the Court of Appeal. He has also advised on contentious matters relating to trade mark, copyright and designs infringement and passing off; predominantly at the pre-action stage, assisting rights holders and alleged infringers with resolving disputes early.

Before moving into law, Marcus worked for five years within the pharmaceutical market research sector developing and managing national and international projects in various medical fields.  Marcus trained and qualified as a solicitor with a leading international law firm and joined Marks & Clerk Law in September 2016.
