A trademark is a brand name or logo used to identify and legally protect a brand's products or services from imitation.

At its most basic, the answer to "what is a trademark?" is simple: a trademark is a unique sign, design, symbol, word, or overall intellectual property that works as an identifier that people associate with a brand or company. It's a service mark that protects a business's brand identity against others using it without permission and helps consumers trust that the products or services they’re buying are real and of good quality.

Think of NIKE or the McDonald's golden arches. When you see them, you instantly know the brand and what to expect from their products or services. A service mark like this is vital for businesses to build a strong connection with their consumers and stand out from competitors.
Trademarks aren’t new — they’ve been used for a long time, even back in ancient times. Today, there are trademark laws - both in the U.S. and around the world - helping businesses keep their identifiers and intellectual property safe by giving exclusive rights to them.

There are two types of trademarks: registered and unregistered. Both have some level of legal protection, but they differ significantly in terms of scope and reliability.
Unregistered trademarks provide limited, local protection. Simply using a trademark—such as adding the "™" symbol to your business name, logo, slogan, or other brand identifiers—signals that you’re claiming the trademark. However, without formal registration, ownership can be harder to prove, and protection is more easily challenged.
Unregistered trademarks also limit your ability to take legal action. You can only pursue claims in state courts, and protection typically applies only within your local area.
Federally registered trademarks provide stronger and nationwide protection. The registration process includes a formal search that helps ensure you’re not infringing on an existing trademark. This reduces the risk of unknowingly violating someone else’s trademark rights, which could lead to expensive legal disputes.
Although registering a trademark involves upfront costs, it’s often a worthwhile investment. Registration provides a clear paper trail, making ownership easier to defend. Moreover, the costs of legal issues or potential rebranding can far exceed the initial costs of registration.
If your business operates in multiple states or at a national level, then you might need a registered trademark to protect your intellectual property. Here are reasons to consider a registered trademark.

Trademarks and copyrights are frequently confused, but they are not the same. Both are types of intellectual property protection, but each is designed for a different purpose.
Trademark | Copyright | |
|---|---|---|
Purpose | Protects a brand's identity (name, logo, slogan, etc.) so that consumers can tell differen t businesses and their products or services apart. | Protects original creations like books, music, art, and software. It gives authors and artists the right to reproduce, share, and display their work. |
Scope | Applies to the specific products or services a business offers. For example, the Nike "swoosh" logo is trademarked for sports gear. | Applies to the way an idea is expressed, not the idea itself. A book may be copyrighted, but not its basic plot. |
Duration | Can last forever if it's used and maintained. In the U.S., it needs to be renewed five years after the federal trademark registration date and at every ten-year anniversary. | Lasts for the author's life plus 70 years. After that, the work enters the public domain and can be used by anyone. |
Registration | You can get some legal protection for a trademark just by using it, but registering it with the USPTO gives you more legal benefits, like nationwide protection and the ability to sue in federal court. | Copyright protection starts automatically when a work is created, but to sue for copyright infringement, you need to register it with the U.S. Copyright Office. |
Trademarks are incredibly flexible. Under U.S. law, practically everything can be registered as a trademark, as long as it identifies a source of goods or services, and is used in commerce. This can include:
Despite their flexibility, there are limits to what trademarks can cover. Examples of things you can't trademark include:
The strength and scope of trademark protection depend on how distinctive a mark is. The USPTO considers several factors to determine this strength, with arbitrary or fanciful marks receiving the most protection, while generic marks cannot be protected at all.
The USPTO requires attorney representation for any business owner without US citizenship.
If you are a US citizen, you don’t legally need a lawyer to register a trademark. However, if you don't know how to file a trademark, there are many good reasons to use a lawyer in the application process:
Basically, while it is possible for US citizens to register a trademark on your own, having legal help can make the process much easier, save you time, and help you avoid expensive mistakes.
