when i submitted my tm application i did not include any pseudo marks, now my mark has been registered for about 6 months and I want to request to add a pseudo mark to my registration. dug around uspto website for 2 days. only thing that is relevant is the Misc. Forms section then form 1: voluntary amendment not in response to open action letter. the description indicates a section 7 form request is required (but very unclear). but that form is only for immaterial changes and adding a pseudo mark would be a material change (the certificate does not include pseudo mark info so it would not change) but the uspto database would change; for material changes it says see TMEP Section 1609.10(a). but that talks only about USPTO errors, this is not an error; what form to use please!?
