Twenty-two-year-old Nathan Cochran pleaded not guilty during an appearance in Payne County District Court on Monday morning.
The charge is the fourth sexual battery charge filed against Cochran. He pleaded not guilty to the previous three charges in December and his attorney says he maintains his innocence.
Prosecutors allege that Cochran molested or attempted to male students while they slept in a dorm room.
OSU has drawn criticism for not immediately reporting the alleged incidents when they first came to light in November. Police say they didn't learn of the case until Dec. 6 when contacted for comment by the campus newspaper.
Cochran remains free on bond.
