BUSINESS BRIEFING / COURTS

Sony Corp. settled a patent-infringement suit filed by Caltech over digital cameras.

Terms weren’t disclosed in a federal court filing in the case. “Caltech hereby informs the court that it has resolved its dispute with Sony Electronics and Tokyo-based Sony Corp.,” the school said in a filing Tuesday in Los Angeles.

Caltech sued six digital-camera companies, including Canon Inc. and Nikon Corp., seeking royalties on 11 patents related to digital-camera technology.

Some of the inventions relate to pixel sensors that improve electronically transmitted images and came from research Caltech did for NASA.
