Sony has countersued high end digital camera maker Red Digital Cinema for patent infringement, two months after Red alleged Sony cameras infringed its patents and called for the cameras to be destroyed.
Sony accused Red of infringing seven of Sony's patents in a suit filed with the U.S. District Court for the Central District of California, it announced in a news release on Friday.
"Sony believes that the Red One, Epic and Scarlet cameras, various digital still and motion camera modules, and various accessories such as the Redmote infringe our patents," Sony said. The Japanese company is seeking monetary damages as well as an injunction to stop the continued sale of Red's infringing products, it added.
"Seems like someone is nervous... it just isn't me," said Red CEO James Jannard in a posting on Red's user forum discussing Sony's litigation. "RED pays many companies royalties to use patented technology," he said in another posting in the same discussion.
Sony said it made significant investments into research and development related to the cinema camera industry and it intends to protect those investments.
The litigation follows a lawsuit filed by Red against Sony in the U.S. District Court for the Southern District of California on February 12. In that suit, Red claimed that Sony's F65, F5 and F55 infringe two of it's video camera patents, according to the court filing.
Red is after a sales and import ban on the allegedly infringing cameras and requested a jury trial. It also asked for unspecified damages and for an order requiring Sony to deliver up and destroy all infringing cameras.
