It could be important to start using your trademark symbol™ as part of your patent and trademark registration. The easy way, using WordPress and Microsoft Word is to go into your word document, enter the letters TM and then press return. It immediately turns into a superscript (smaller letters raise a bit higher). Copy and past that TM symbol and drop it into your WordPress page or post. Make sure you have the editing tab on Visual (not HTML). WordPress will convert it to the right HTML code.
