Google CFO George Reyes plans to leave the company at the end of the year.
Google announced last Tuesday that Reyes would step down after assisting in a search for a replacement.
"I've known and admired George since our days together at Sun," Google chairman and CEO Eric Schmidt said in a statement. "As Google's CFO, George successfully navigated our innovative IPO, the regulatory demands of Sarbanes-Oxley, and the management challenges of scaling a global finance organization. Though we fully appreciate his decision to step back from active management, we'll miss his thoughtfulness, good humor, and wisdom."
Six major Internet companies have been sued for using computers to process their e-mail.
AOL, Amazon, Borders, Google, IAC, and Yahoo stand accused of violating a patent on automatic message routing held by Texas-based Polaris IP.
Attorneys representing Polaris IP filed a claim of patent infringement on Monday in U.S. District Court of the Eastern District of Texas in Marshall, Texas.
The lawsuit charges the companies with implementing systems that "comprise interpreting electronic messages with rule base and case base knowledge engines" as described in the patent held by the plaintiff, "Automatic message interpretation and routing system."
