Federal Registration Symbol

When a company creates a unique logo, symbol, phrase, or any unique visual element to present their product or service to the public in packaging or advertisement mediums, that element is automatically protected under United States intellectual property law. 
They may bear a TM symbol or a SM symbol next to the trademark element to indicate this protection. If a company would like added protection and further security, however, they will need to register their trademark or service mark with the United States Patent and Trademark Office (USPTO). 
After a successful registration, the trademark or service mark will be recognized by the USPTO and receive federal trademark registration benefits, indicated by a circled “R” after the mark. The circled R is usually presented after the element in a superscript style.
Although it can be written as (R) or (r) due to a lack of a typewriter character to represent the symbol, the registered trademark symbol appears as follows:
[Registered Mark]®
Material which has not received an official registration with any office around the world cannot legally bear the  circled “R” trademark symbol.

SM Symbol

SM Symbol

The service mark symbol is a symbol that designates a symbol as a service mark. A service mark is a form of a trademark symbol used in many countries, usually in the United States, to identify a service rather than a physical product. They are used to identify services which have not yet been registered with the United States Patent and Trademark Office 
The service mark is identified by “SM” written in a superscript format directly after the trademark material. The service mark appears as follows:
[Service Mark Material]℠
The trademark sign indicates that the trademarked material used by the company is intended to distinguish their services from other company services. This also helps customers by helping them to identify and distinguish between differing companies offering similar services.
