Synopsys, Inc. (NASDAQ: SNPS) today announced that the United States District Court for the Northern District of California has ordered Magma Design Automation to immediately withdraw its claim of ownership to the '446 and '438 patents and to transfer title to Synopsys. These patents are at the heart of the ongoing litigation between Synopsys and Magma.

"This ruling confirms what we've been saying all along. Magma has no ownership interest in any of the fixed timing inventions at the core of our claims in this case," said Brian Cabrera, Synopsys general counsel. "We look forward to proceeding with the balance of the case after the court issues its ruling in the ownership phase."

The ruling, which addresses Synopsys' December motion for preliminary injunction against Magma, ensures that Synopsys' ownership of the patents is officially reflected and protected during the current proceedings before the Patent and Trademark Office.
