Apple recently has been involved in a number of patent lawsuits with competitors using the Android OS. A new discovery by FOSS Patents, reveals that Apple has also sued Motorola in Europe, claiming that the Motorola Xoom tablet infringes the design of Apple’s products. This was revealed in a court document filed in Germany and associated with the preliminary injuction given against Samsung yesterday banning the sale of the Galaxy Tab 10.1.

Prior to or simultaneously with the motion for a preliminary injunction against Samsung, Apple also filed a complaint with the same court over the design of the Motorola Xoom tablet. Here’s a passage from the Samsung complaint that mentions two other lawsuits Apple instigated against iPad competitors — Motorola and a local German company named JAY-tech…

The filing does not say whether or not  Apple has pushed for a preliminary injunction against the sale of the Xoom in the European Union as it did for the Galaxy Tab 10.1. However, Apple is considering a  permanent injunction against Motorola’s Xoom.

In addition, the filing also notes that a preliminary injunction against  JAY-tech  was granted and further upheld “in its entirety” following a hearing.  JAY-tech last year began offering a budget 7-inch Android-based tablet, and the company is no longer selling the product.

Last year, Motorola filed a suit against Apple  claiming infringement of a series of 18 Motorola patents with a broad array of Mac and iOS products. Since then, the two companies have been quiet between each other but today’s  revelation suggests that  Apple has continued to go after Motorola.
