Mr Cosby, 85, is embroiled in a civil lawsuit over a claim he sexually assaulted Judy Huth, now 64, at the Playboy Mansion in Los Angeles in 1975.
The case is one of the last remaining legal actions against Mr Cosby, who has faced numerous abuse claims.
He has denied any assault took place, and is not expected to testify.
According to a lawsuit filed by Ms Huth in 2014, the incident took place when she was 16 years old, days after she met Mr Cosby at a park near Los Angeles where he was shooting a film.
