Do you have to use R every time?
No, you don't need to use the registered trademark symbol with every instance of the mark in question. The general rule is to use it with the most prominent (and generally first) instance of the mark on a given web page, publication, etc.
Should I use TM?
TM or SM are for unregistered marks only. Use TM for marks that represent goods and SM for marks that represent services. If your mark covers both goods and services, use TM. The federal registration symbol, ®, is only for marks registered with the USPTO.
How do you properly use a trademark?
If the mark is registered, use the superscript ® symbol or other appropriate notice of registration instead. Always use the trademark consistently, including the same spelling, punctuation, and spacing. Always use a trademark as an adjective that modifies a noun, and never as a singular or plural noun.
What's the difference between R and TM?
Many people use ™ and r symbols synonymly but there are some key differences between both. The TM symbol is typically used during the trademark application process for registering a specific product or service. While the ® symbol can only be used after a trademark has been successfully registered.
