WWE abandoned their "EC3" trademark on Saturday, January 25.
WWE originally filed for the EC3 trademark back on June 21, 2019. The trademark filing was abandoned last month due to the company not responding to the initial notice of refusal within the given 6 month period. The notice was issued on July 24 of last year. The refusal was issued because EC3 already filed to register the trademark for himself on April 23 of last year.
WWE will be able to to re-file their own application for "EC3" at a later date.
EC3 remains on the WWE RAW roster, but is rarely used these days.
