Actor Jason Patric is celebrating after landing the right to fight for custody of his four-year-old son Gus. The Speed 2 star and his lawyer appeared on U.S. breakfast show Good Morning America on Thursday (15May14), a day after officials at a California appeals court granted him permission to claim parentage of the kid, who was conceived through artificial insemination. Calling the victory "surreal", Patric said, "It's been 64 weeks since I've seen Gus, and I always believed that we were going to win this appeal because it was just wrong... and I had faith in the process." The actor and his ex-girlfriend, Danielle Schreiber, have been battling over Gus' parentage for close to two years. A Los Angeles Superior Court judge previously denied Patric access to his son, based on California law that grants the mother full custody unless there is a written agreement establishing parental rights before conception. The case has been remanded back to the trial court and Patric's attorney revealed on TV that they plan to get the actor's visitation rights reinstated next week (beg19May14), before continuing their fight for custody. Patric said, "In his (Gus') mind I just disappeared. I didn't tell him the truth. And it's something that I deal with every day. "I have been a dad and I'm going to continue to be a dad. You can't ever abandon a child." Making the case for his client on GMA, the actor's lawyer added, "He's not a donor. That's the issue... He went to a clinic with Danielle in order to have a child together, so we don't want to characterise him as a sperm donor in that sense. The issue is the law has now been clarified by the court of appeal, and in fact changed, and these two competing statutes that created this problem have now been reconciled."
