A key pretrial hearing to determine what evidence prosecutors can use in Bill Cosby's Pennsylvania sex assault case has been scheduled for early November.

Prosecutors hope to call 13 other accusers to show the comedian had a pattern of drugging and molesting women. The criminal charges involve an encounter with Andrea Constand in 2004.

Prosecutors also want to use Cosby's deposition from Constand's 2005 lawsuit. Cosby acknowledges under oath that he had sexual encounters with a series of women after giving them drugs or alcohol.

The defense will push to keep the deposition out at the hearing set for Nov. 1-2.

Lawyers for the 79-year-old Cosby say it's impossible to defend a decade-old case.

Prosecutors reopened the case last year after the deposition was unsealed.

Cosby has pleaded not guilty.
