Wireless transmission suit lodged

Ohio-based R+L Carriers is suing chipmaker Qualcomm in the US District Court of Ohio, alleging the company infringed its patent related to the wireless transmission of documents from a motor vehicle, reports American Chronicle.

The freight transportation services company claims that three Qualcomm products that provide communication services infringed on its wireless transmission patent.

Earlier in March, the company filed a similar suit in the same court against petroleum distribution logistics software provider SmartLogix.

A federal appellate court has sided against adware company Zango in its dispute with spyware removal vendor Kaspersky Lab, reports MediaPost.

The 9th Circuit Court of Appeals ruled last week that Kaspersky is immune from liability for offering programs that delete ad-serving software.

"A provider of access tools that filter, screen, allow, or disallow content that the provider or user considers obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable is protected from liability," the 9th Circuit wrote.

Sony has settled a patent-infringement lawsuit filed by the California Institute of Technology over digital cameras, according to the Los Angeles Times.

Some of the inventions relate to pixel sensors that improve electronically transmitted images and came from research CalTech did for the National Aeronautics and Space Administration, according to information on the patents.
