Jason Patric's Baby Mama -- He Called Me 'Jew C**t' & 'Jew Lawyer' ... And Beat Me with a Phone

9:10 AM PT -- Danielle's attorney Patty Glaser is now responding, telling TMZ, "Mr. Patric's reprehensible physical abuse and anti-Semitic remarks date back as far as 2005. Unfortunately, victims of domestic violence ask themselves all the time why they maintained relationships with the abuser and when they realize what happened no longer tolerate it."

She adds, "The fact that the domestic violence restraining order was issued after a family court judge heard Ms. Schreiber's and Mr. Patric's testimony speaks for itself."

Jason Patric repeatedly called his baby mama "Jew c**t" and "Ms. Jew Lawyer" ... this according to the baby mama herself.

You probably know ... Jason has made a cause celeb out of the fact that a quirk in the law prohibited him from having a relationship with son -- Gus, now 4, was born via in vitro fertilization with the help of a doctor ... and under California law since Jason wasn't married to the mother he had no right.

Jason appealed for public sympathy and enlisted the help of a number of celebs. An appeals court has just given him a shot at winning some custody.

But baby mama Danielle Schreiber sees Jason as anything BUT sympathetic. In legal docs filed with the court and reviewed by TMZ ... she claims Jason was a monster, slamming her head into a wall and hitting her in the face with a telephone receiver.

And she says he was awful to her, regularly referring to her as ""Jew C**t" and "Ms. C**t Schreiber." She says Jason's anti-Semitism continued when he went to their son's preschool, and in front of everyone ... called her "Ms. Jew Lawyer" and "Ms. Jew Schreiber." She says he also accused her of being "c**tish" -- in front of everyone.

Schreiber got a restraining order in November, prohibiting him from contacting or harassing her.

For Patric's part, his lawyer, Fred Silberberg, calls the allegations "categorically untrue." He tells us, "These disclosures are a last gasp attempt at disparaging Gus’ father ... [They] are desperate comments from a desperate woman."

The lawyer adds, "If Ms. Schreiber is telling the truth, which she is not, then she should explain how it is that she chose to have a child with Mr. Patric, why she engaged in years of fertility treatments with him, lived with mr. Patric ... [and] maintained a relationship with [him] for over 10 years."
