Apple has removed the iPhone 3GS, the iPhone 4 and all 3G-capable iPads from its online store in Germany.
"At this stage I am absolutely convinced that the removal of those products from Apple's online store is a result of Motorola Mobility's enforcement of a ruling that was handed down in early December, and not related to today's ruling," Mueller said.
"It must be nothing more than a coincidence that Apple's announcement of the removal of products -- which some observers believe already happened last night, prior to the ruling -- comes on the day of a different court decision."
Today's court decision referred to by Mueller also went in Motorola's favour and a Manneheim court granted the company a permanent injunction against the push email service of Apple's iCloud and any devices that can access it.
But the removal of the iPhone 3GS, iPhone 4 and 3G-capable iPads from the German Apple Store is more likely to do with Motorola's victory in the December case and a dispute over patents relating to the GPRS radio communication standard.
However, the iPhone 4S, which uses a Qualcomm baseband chip unlike the other devices which use chips made by Infineon and Intel, doesn't fall foul of the previous injunction.
Germans can still buy the products from Apple Stores and third-party retailers in the country, according to Mueller.
UPDATE 1600GMT: Apple says it will reinstate the products on the German Apple Store website after a court this afternoon lifted the injunction, reports the BBC.
"All iPad and iPhone models will be back on sale through Apple's online store in Germany shortly. Apple appealed this ruling because Motorola repeatedly refuses to license this patent to Apple on reasonable terms, despite having declared it an industry standard patent seven years ago," the company said in a statement.
