It appears that there is no end in sight for the patent wars between tech giants. Virtually every major tech company is embroiled in patent litigation, not with one adversary but with many of them. This has also recently attracted criticism towards the US Patent office.

Microsoft has been pursuing Motorola Mobility rather aggressively. In Germany, Microsoft has so far won three patent infringement cases against Motorola, which has recently been acquired by Google. In a fourth case, however, the court has ruled that Motorola didn’t infringe any Microsoft patents.

The patent over which Microsoft was leading the charge against Motorola concerned the ability of an app to run across multiple handsets. Although Motorola won on this case, this may be only a brief win for Motorola since Microsoft has already been granted injunctions to ban the sales of a number of Motorola handsets in Germany.

According to the associate general counsel for Microsoft, David Howard, “This decision does not impact multiple injunctions Microsoft has already been awarded and has enforced against Motorola products in Germany.” Although Google acquired Motorola apparently with the intent of bringing home Motorola’s huge patent portfolio, it seems that the search engine giant will have to  cope with the many patent-related issues that are attached with Motorola.
