Apple has pulled several iPad and iPhone models from its German online store after Motorola Mobility enforced a patent injunction against its rival, reports the "BBC" (http://macte.ch/7GmXq).

The move follows a December ruling that Apple had failed to license one of Motorola's wireless intellectual properties. iPhone users in Germany may also face the loss of their push email iCloud service after a separate patent victory by Motorola, notes the "BBC." Apple has said it will appeal.

This is part of an ongoing battle. Earlier this month the U.S. International Trade Commission (ITC) ruled that Motorola's Droid smartphones don't violate three Apple patents. The ruling is preliminary and needs to be approved by the ITC's full six-member commission.

Apple has previously alleged that Motorola infringes 24 of its patents (21 of them with Android-based phones, the remaining three with set-top boxes and DVRs), while Motorola previously asserted 18 patents against a variety of Apple products (mostly but not exclusively iPhone, iPad and iPod). Litigation between the two companies has taken place in several different federal courts -- primarily the Western District of Wisconsin and the Southern District of Florida -- as well as before the ITIC.

In November 2010 Apple sued Motorola, alleging that the company's smartphone lineup and the operating software it uses infringe on the iPhone-maker's intellectual property. The two lawsuits came after Motorola sued Apple in October 2010 for patent infringement. Motorola claims that Apple's iPhone, iPad, iPod touch and certain Mac computers infringe Motorola patents.
