Apple’s chief patent lawyer will soon leave the company amid ongoing legal battles with Samsung and HTC, among others. Attorney Richard “Chip” Lutton Junior currently manages Apple’s extensive portfolio of patents, but not for much longer according to a report on Tuesday from Reuters. The lawyer is leaving Apple for reasons unknown according to Reuters’ seemingly well-placed anonymous source, and B. J. Watrous will replace him. Watrous, formerly Hewlett-Packard’s deputy general counsel, is already listed as Vice President & Chief IP Counsel for Apple on his LinkedIn profile. Apple has sued a number of companies around the world recently for patent infringement, including Samsung, HTC and Nokia. HTC responded to Apple’s most recent patent complaint by stating that the company should focus on competing in the market instead of constantly suing its competitors.
