Now it’s getting interesting. In a previous post about Dropbox I guessed that the extensions for time to oppose the Dropbox trademark registrations were likely to be over whether Dropbox was descriptive. Yousendit was granted an additional 60 days to oppose, but Officeware (owner of filesanywhere.com) and Box.net have filed their oppositions, not because of a contention that Dropbox is descriptive, but because of claims of prior use and likelihood of confusion with their marks.

Box.net Opposition to Dropbox Registration
A reader brought to my attention Officeware’s trademark infringement lawsuit in Texas, alleging priority for filesanywhere.com’s common-law trademark use of “Dropbox.”
FilesAnywhere v. Dropbox Complaint
Filseanywhere asserts use of “Dropbox” since 2004 and use of a blue open box logo since 2006. Dropbox was founded in 2007.

Officeware is owned by Immediatek, a company traded on the OTC Bulletin Board. Immediatek had revenues of about $2 million last year, but a net loss of $800,000. Billionaire Mark Cuban is a major investor of Immediatek. Dropbox is a private company, but had revenues of more than $100 million in 2010 and has significant venture capital funding.
