On July 19th, Rick Quereshi filed a Notice of Opposition against Twitter’s application for the mark TWEET. Although Twitter applied for trademark protection of TWEET back on April 16, 2009, and the application was published for opposition later that year, Quereshi opposes the registration for the following reasons: 1) Twitter filed its application under an intent to use basis, yet no Allegation of Use has been filed to date; 2) Twitter has not used the TWEET mark in commerce with the identified classes of services from the application; and 3) Quereshi has been openly and notoriously using the TWEET mark in commerce via a mobile computing device since July 23, 2009. Thus, under the doctrine of common law, Quereshi claims ownership of the mark TWEET due to its prior senior use.
