In applying for a trademark 009 registration for [computer application software for mobile phones, namely, software that provides information in the fields of outdoor recreation, investment real estate, and personal cosmetics] does the first use for one field (e.g., outdoor recreation) constitute the first use for all? Before you apply for the registration do you have to have started commercial use in all fieldsl? Or just one field? (I don't want to use the "intended use" option). Do you have to supply a specimen for the use in each field, or just one field? (The trademark is uniform for all.)
