Hedge fund manager Kyle Bass said he challenges drug patents for profit -- but so does everyone else.

Responding to claims by Celgene Corp. that he’s abusing a process set up to review issued patents, Bass said a profit motive is at the heart of every patent and every patent challenge. Betting on a company’s stock price falling is legal, and the public stands to gain if fewer patents stood in the way of cheap copycat medicines, he said in a filing Tuesday.
