Motorola Mobility does not infringe a Microsoft radio interface patent, the lower regional court of Mannheim ruled on Friday, denying Microsoft another sales ban on Motorola devices in Germany.
Microsoft had accused Google-owned Motorola Mobility of infringing on a patent that describes a radio interface layer that provides a level of abstraction between the radio and software on a cell phone. This patented technology allows applications on the phone to access the phonebook entries, restrict access to data and access file and message storage among many other functions, according to the patent.
Microsoft sued Motorola in Germany, asking the company to pay licensing fees on its Android-based smartphones as rivals HTC and Samsung Electronics have done.
"This decision does not impact multiple injunctions Microsoft has already been awarded and has enforced against Motorola products in Germany," Microsoft said in an emailed statement. "It remains that Motorola is broadly infringing Microsoft's intellectual property, and we hope it will join the vast majority of Android device makers by licensing Microsoft's patents."
Motorola did not immediately respond to a request for comment.
Microsoft already has three injunctions against Motorola in Germany for infringing an SMS patent, a FAT file system patent and a patent describing a method for handling communication between a keyboard and an application.
The two earlier German injunctions are being enforced and the third one will be soon. One of the rulings included a sales ban on the Motorola Atrix, the Droid Razr and the Droid Razr Maxx.
Microsoft also has an injunction against Motorola in the U.S., where the International Trade Commission ruled that Motorola infringes on an ActiveSync patent. That ruling prevents Motorola from importing infringing products into the U.S.
