Google and 47 other international corporations have been sued in a US District Court for trademark infringement over their use of the word "Android."

To Google, Android is the name of its open-source, Linux-based operating system for phones and mobile devices that it introduced in November of 2007.
To Erich Specht, a software developer and internet applications service provider in the Village of Palatine, Illinois, Android is part of the name of his company, Android Data, for which he was granted a trademark in October of 2002 by the US Patent and Trademark Office (USPTO).
