Must all trademarks be registered? No, registration is not mandatory. You can establish “common law” rights in a mark based solely on use of the mark in commerce, without a registration. However, federal registration of a trademark with the USPTO has several advantages, including a notice to the public of the registrant's claim of ownership of the mark, a legal presumption of ownership nationwide, and the exclusive right to use the mark on or in connection with the goods or services set forth in the registration. For more information about “common law” trademark rights and the advantages of federal registration see the Basic Facts About Trademarks brochure.

Each time you use your mark, it is best to use a designation with it. If registered with the USPTO, use the ® symbol after your mark. If not yet registered, you may use TM for goods or SM for services, to indicate that you have adopted this as a “common law” trademark or service mark.

You do understand that Canapsor hasn't been trademarked - that is extremely unusual and shows a lack of competence.
