When Robert Armitage retires from his post as general counsel of Eli Lilly and Company at the end of the year, he will be leaving his mark not just on the company but also on the laws governing intellectual property in the United States.

Eli Lilly announced recently that Armitage, who is approaching mandatory retirement age, will retire December 31 and will be replaced by the company’s current deputy general counsel, Michael Harrington. (See: “Eli Lilly General Counsel Steps Into Big Legal Shoes.”)
