A federal judge has invalidated one of Samsung's patents and found that a second infringed on a patent owned by Apple in an ongoing court battle that could force the South Korean company to stop sales of certain devices.

In a partial summary judgment, Judge Lucy Koh of the U.S. District Court of Northern California on Tuesday invalidated Samsung's patent on multimedia synchronization between tablets, phones and servers, and found that a second patent infringed on Apple's autocomplete text feature on mobile devices.

The findings give Apple the upper hand in a multi-patent trial scheduled for March 31. Apple still has five other patents involved in the case and Samsung has four, according to court documents published by intellectual property blog FOSS Patents.

A ruling by a jury in March will determine a fair dollar amount for Samsung to pay for these violations, and Koh will determine whether there should be an injunction to stop U.S. sales of Samsung devices, including the Galaxy S3. Apple CEO Tim Cook and Samsung CEO Oh-Hyun Kwon will meet on Feb. 19 in an attempt to mediate the patent case – another instance in which Koh's findings give Apple an advantage.

The court case dates back to 2011, when Apple accused Samsung of infringing on the look and feel of its products. During a trial in August 2012, Apple tried to show that Samsung did not sell products that looked and operated similar to the iPad and iPhone until after they were launched by the California-based tech manufacturer.

Previous verdicts determined Samsung already owes Apple approximately $845 million.
