Google and Motorola Mobility have been ordered to provide information related to the development of the Android mobile OS to Apple, reports Bloomberg.

The US judge overseeing a patent lawsuit brought by Apple in 2010 against Motorola – and subsequent counter suit – has told Motorola and Google to provide the information to inform Apple’s claims and defence.

Motorola makes phones using Android, which Apple claims infringes patents it owns, and is currently the subject of a US$12.5 billion takeover by Google. Motorola has argued that as Google doesn’t yet own the company, it isn’t party to the lawsuit filed by Apple in 2010, so should not be expected to provide the information requested by Apple.

US Circuit judge Richard Posner made the ruling in Chicago and has scheduled back-to-back trials for the two lawsuits starting on 11 June, according to Bloomberg. The first trial will cover six Apple patents while the second will cover three patents held by Motorola.

Apple last month filed an antitrust complaint against Motorola with the European Union about the proper use of patents. The two companies have been involved in legal action about the use of patents in the US and Germany for some time with the most recent ruling seeing Motorola win a permanent injunction against Apple’s iCloud service in Germany, which could lead to a ban on the sale of iPhones and iPads in the country.
