Apple claims Google is withholding information about Samsung’s use of the Android source code. The company is now asking a judge to force Google to turn over documents related to Android as part of its second patent infringement lawsuit against Samsung, Bloomberg reported. Apple argued that Samsung uses Android in all of its infringing products and the platform “provides much of the accused functionality” in its claims. Apple is concerned that Google isn’t doing proper research to locate the files and would like U.S. Magistrate Judge Paul S. Grewal to intervene.

Matthew Warren, a lawyer for Google who is also representing Samsung, explained to the judge that turning over the requested information Apple is seeking could lead to “future discovery that we don’t think they’re entitled to” and give the company “ideas about how to proceed that they wouldn’t have had.”

The latest patent infringement case between Apple and Samsung concerns newer smartphone models, including the iPhone 5 and Galaxy S III. Apple was previously awarded $450.5 million in damages from Samsung, however a second hearing concerning damages is scheduled to take place in November .
