If you have filed your trademark with us, we will inform you that your trademark has been objected by the Registrar less than a month from the publication of the Examination Report containing the objection. If you are not a customer, it's best you contact us within a month from the publication of the report.
We will put you in touch with our lawyers, who will understand your case and frame the correct response and affidavit (if required). The response will be submitted.
If the Registrar does not accept your initial response, an interview is scheduled, where the arguments would need to be presented in person. If the government is satisfied with the response, the objection will be lifted within 18 months.
By the time of the objection, you would have been using the ™ symbol for a few months. Your customers would have likely become accustomed to the brand name. Filing a new application would not make business sense. Instead, you could simply identify the list of reasons your logo, slogan or brand name are different.
