USPTO changed its mind and soften the requirement for providing an owner email address in every trademark application for the US. This was required apart from the email of the industrial property representative or trademark attorney.
According to the amendments, this second mail will be still required, however, it could be not the owner’s email. That is to say, apart from the attorney email every applicant has to submit another email address too.
