Enforcing your trademark
Using the ® Symbol
You do not have to identify your trade mark as registered but you can use the ® symbol to show that your trade mark is registered, the mark can be registered somewhere other than in the United Kingdom.
The ® symbol usually is usually placed on the right-hand side of the trade mark, in a smaller type size than the mark itself, and in a raised (superscript) position; none of this is compulsory.
Is it illegal to use the ®?
You would break the law (Section 95 of the Trade Marks Act 1994) if you use the registered symbol ® on a mark that is not registered anywhere in the world.
Am I breaking the law by using “TM” on my trade mark?
No, as this does not indicate that your trade mark is actually registered, only that it is being used as a trade mark. The symbol ‘TM’ has no legal significance in the United Kingdom.
So registered= ® unregistered= tm
