The online "microblogging" service Twitter filed suit
last month against Twittad, LLC, a company that enlists Twitter
users to participate in advertising campaigns for pay. Twittad has
registered the phrase LET YOUR AD MEET TWEETS with the United
States Patent and Trademark Office (PTO) as an identifier for its
advertising-related services. The lawsuit represents the latest
step in Twitter's efforts to assert proprietary rights in the
term "tweet," which, according to the Online Etymology Dictionary, has been used
since at least 2007 as "the word for what one does" on
Twitter.
Twitter launched its service in 2006 and first filed to register
its trademark in the name TWITTER in 2007. When it came to filing
trademark registration applications for TWEET, however, Twitter was
a bit late to the party. It first applied to register TWEET for
blogging, telecommunications, and social networking services on
April 16, 2009. This application has been suspended pending
resolution
