CBS has sued a photographer for copyright infringement for publishing a still image from a 59-year-old television show. From a report: The lawsuit against New York photojournalist Jon Tannen, filed on Friday, is essentially a retaliatory strike. Tannen sued CBS Interactive in February, claiming that the online division of CBS had used two of his photographs without permission. Now, CBS has sued Tannen back, claiming that he "hypocritically" used CBS' intellectual property "while simultaneously bringing suit against Plaintiff's sister company, CBS Interactive Inc., claiming it had violated his own copyright." "Without any license or authorization from Plaintiff, Defendant has copied and published via social media platforms images copied from the Dooley Surrenders episode of GUNSMOKE," write CBS lawyers. CBS is asking for $150,000 in damages for willful infringement.
