Trademarks (for goods) and service marks (for services) are words, names, symbols (and even sounds and smells) used by manufacturers to identify their goods and services, and to distinguish their goods and services by those manufactured by other companies. Some examples of trademarks include: Apple® for computers, MGM lion's roar, and Tylenol® for medicine.
What is the difference between ™, ® and SM?
Using the symbols ®, TM and SM alongside your mark all provide notice to the world that you are claiming trademark rights. The TM symbol signifies marks identifying goods, while the SM symbol signifies marks identifying services. You need not have a federal or state registration to use the TM or SM symbols; you can claim a common-law right to the mark. However, the ® symbol, which provides statutory notice can only be used if your mark is federally registered by the United States Patent and Trademark Office (USPTO).
By having a registered mark, you can greatly reduce the number of people that infringe upon your mark, simply because the mark is included in searches performed on the USPTO website. Most business owners would prefer to come up with another name for their business or product to avoid a conflict. Additionally, the USPTO will not register confusingly similar marks.
Do I have to be a
No, but an applicant’s citizenship must be included in the trademark application.
Once my mark is registered, do I have to do anything else?
Most definitely! Policing your mark is something that is the duty of the business owner, and should be done on a regular basis. Trademark rights come with exclusive use, and you have to exercise this right in order to maintain it.
