Patent Infringement Ruling In Favor Of Midtronics Upheld On Appeal

The U.S. appellate court has upheld a lower court’s ruling from 2011 that Argus Analyzers and BP Power sold products containing electronic battery testing technology infringing on patents held by Midtronics. The original complaint was filed six years ago. It was argued that BP Power, a Taiwanese company, developed the infringing products, and Argus imported and sold them in the United States.

In August 2011, U.S. Judge Milton Shadur of the Northern Illinois District ruled in Midtronics’ favor, ordering the defendants to stop making, importing, using and selling a number of their products, including AA350, AA400, AA500, AA500P and AA550P battery testers. Shadur also ordered the defendants to pay attorney fees and expenses.

Argus and BP Power appealed Shadur’s ruling in 2011. The U.S. Court of Appeals for the Federal Circuit in August 2012 unanimously affirmed Shadur’s ruling, and none of the relief sought in the appeal was granted. No opinion accompanied the judgment.

“The court’s decision definitively validates one of our foundational patents and the strength of our intellectual property portfolio,” Steve McShane, president and CEO of Midtronics, said in a statement. “Midtronics will vigorously defend our innovative technologies as we continue to invest in and advance battery management.”

As of press time, we had not received a formal statement from Argus in response to the appellate court’s decision.
