A company called ART+COM Innovationpool GmbH (ACI) has announced this week that it has filed a patent infringement suit against Google. The suit has to do with Google allegedly infringing on a patent that ACI holds. The patent in question is # RE44,550. The title of that patent is "Method and Device for Pictorial Representation of Space-related Data."
ACI takes issue with how much Google Earth looks like its Terravision service. Terravision is the commercial implementation of the patent at the heart of the case. ACI says that Terravision was developed a decade before Google Earth.
Looking at the image here, it is clear that the Terravision service and Google Earth are very similar in how they look. ACI also says that it has issue with some of the executives at Google, particularly Michael Jones, CTO of Google Earth, and Brian McClendon, VP of engineering for Google Maps.
