The right approach depends on what you want to protect and how the brand is used. Share both for a discussion about the filing scope.
An application can be filed on a proposed-to-be-used basis. If you claim earlier use, supporting evidence and a user affidavit are required.
Classes group goods and services. Your business activity determines the relevant classes; more than one may be needed.
The quote depends on the applicant category, marks, classes and work involved. Ask for official and professional fees to be shown separately.
Timing depends on Registry processing and whether objections or opposition arise. A filing acknowledgement is not a registration certificate.
No. The Registry decides after the applicable examination and opposition stages. A search helps assess risks but cannot guarantee acceptance.
