A company may register its trademark or service mark with the Secretary of State by filing the completed form, Registration of Trademark and Service Mark (Secretary of State form LP/TM 100) along with a fee of $70. The regulations governing the registration of these are rather complex; a company should obtain specific instructions directly from the Secretary of State.
