Apple wins over case filed by Optimum Power Solutions

In 2011, Optimum Power Solutions filed a complaint 3:11-cv-01509 against Apple, Dell, HP, Lenovo and Sony Electronics for their infringement of various claims of the U.S. Pat. No. 5,781,784 entitled ‘Dynamic power management of solid-state memories’ that issued on July 14, 1998. This post briefly summarizes the verdict rendered in this case on March 19, 2013.

The infringing products as said in complaint were Apple MacBook Pro, Dell Studio1555 Notebook, HP Pavillion dv3-2150us notebook, Lenovo ThinkPad T500 and Sony Vaio Z notebook. 

The case initially started with 5 defendants who were then reduced to 1 due to the dismissal of 4 defendants in September 2011 and the case proceeded to trial with Apple as sole defendant. In the final verdict, Optimum Power Solutions lost on all its claims as Judge, William H. Alsup, ordered non-infringement of the patent in favor of Apple and dismissal of the case without prejudice.

The ‘784 patent expired on Jul 2012, when the case was in hearing, and it appears that the plaintiff may not appeal the verdict.
