OIIM O2 Micro International Ltd

O2Micro(R) International Limited (Nasdaq:OIIM), a leading supplier of innovative power management, and security components and systems for the Computer, Consumer, Industrial, and Communications markets, was granted 19 claims under GB (Great Britain) patent number 2,398,403 for its Power Switch device for PC Cards.
