Kalau dari definisinya sendiri the "
trademark symbol", which is the letters "TM" in superscript, for an
unregistered trademark, a mark used to promote or brand goods. Artinya gak ada larangan bagi siapapun untuk menambah tanda TM di brand masing-masing, selama brand tersebut belum dimiliki oleh orang lain walaupun belum dalam tahap registrasi. ini biasa dipakai didalam desain grafis, desain font dll.
An unregistered or
common law trademark is an enforceable mark created by a business or individual to signify or distinguish a product or service. A common law or
unregistered trademark is legally different from a registered trademark granted by statute.
As with statutory trademarks, a common law trademark utilizes graphics, images, words or symbols, or a combination of such, to signify the distinctiveness or source of a product or service.
Although not required by law to receive trademark protection, an unregistered trademark owner can append the mark with the letters "TM" (visualized by the
trademark symbol ™). A ™ serves as notice to the public that the words or symbols are an unregistered trademark. In contrast, trademarks granted by the United States Patent and Trademark Office (USPTO) may have the ® symbol next to the trademark. The USPTO prohibits a common law, unregistered trademark owner using the ® in the trademark.
