The GMAIL thing is interesting. The press release announcing Google’s email service is dated April 1, however media broke the news on March 31. One company, Cencourse, filed a trademark application for GMAIL for email services on March 31 claiming March 31 as a date of first use (so presumably there’s a specimen – but the applicant also checked the wrong box, claiming intent to use as well, so maybe there isn’t). Two other companies filed applications claiming prior use. Google filed an intent to use application on April 7.
This article details the whole complex situation.
Apparently there’s also a Google IPO or something.
