Kenyon won a motion for summary judgment and obtained a dismissal of the patent infringement case filed against Volkswagen by Service Reminder, LLC, a subsidiary of well-known non-practicing entity Acacia Patent Acquisition Corporation. The case involved infringement claims related to a patent on a device that notifies a driver to perform a vehicle maintenance task. Kenyon successfully convinced the Eastern District of Michigan court that Service Reminder's patent was invalid based on anticipation by prior art. Kenyon had previously won a motion to transfer the case from the District of New Jersey, where it was originally filed, to Michigan, which is one of the less favorable jurisdictions for patent holders litigating infringement issues. Case number 10-civ-12201 (2011).
