Vole sued over mouse

MICROSOFT RECEIVED a writ alleging it breached the patent of a mouse designed by Jack Lo.

The writ, issued in a Texas district court two days back, alleges that Microsoft, a co-defendant with Designer Appliances Inc, breached patent number 5,576,733 called "Ergonomic Computer Mouse".

The patents breached, claimed Lo, were incorporated in the Natural Wireless Laser Mouse 6000 from Microsoft, and the Air O2 bic mouse - formerly called the Quill mouse by Designer Appliances.

Illustrated below are Lo's mouse from his patent, and the Microsoft mouse from the Vole's web site.
