The lawsuit filed in Manhattan federal court said Goldman shareholder James Mercer of Kirkland, Washington, sought judgment for profits from any transactions and other relief.
Rajaratnam, 53, was convicted last month on charges of securities fraud and conspiracy for insider trading, including Goldman corporate secrets leaked to him by his friend Gupta. The former director is an unindicted co-conspirator in the case and denies any wrongdoing.
Gupta's lawyer could not immediately be reached to comment.
The case is James Mercer v Rajat Gupta, U.S. District Court for the Southern District of New York, No. 11-3828.
