PTO Declares Dead 6-Year-Old 'International Consumer Electronics Show' Trademark

CTA let lapse its six-year-old registered trademark to the name "International Consumer Electronics Show," Patent and Trademark Office records show. PTO canceled the registration Aug. 2 after CTA didn't meet the July 1 deadline for filing the required "declaration of use" or "excusable nonuse" forms for the registration to continue, said the agency. CTA still owns five active registered CES trademarks, including two that contain the word "International," PTO records show. CTA didn't comment.
