I'm officially an 'inventor' according to the US Patent and Trademark Office (USPTO) for Patent 7,174,152. The patent that was filed while a was working at Sprint in 2003 was recently approved.
System for event correlation in cellular networks was a fun project to work on, but we'll have to wait and see if Sprint really uses it for anything.
The process to get a patent filed, documented, etc. was certainly interesting. There is a dialect specifically created by lawyers when writing patents, it's pretty amazing how complicated it gets to understand the actual description of a patent.
