A regional court in Germany on Thursday postponed a ruling on a case brought by Apple against Google’s Motorola unit over alleged patent infringement until Sept. 13, a court spokeswoman told the “Wall Street Journal” (http://macte.ch/XoLRM). The ruling was originally scheduled for today.

Apple has 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).

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.
