Business names and product names have much in common, however when it comes to trademarks there are some differences. First and most importantly, product names can always be trademarked if the name does not infringe another name.
For more information on how similar a name can be: Trademarks: Likelihood of Confusion - University of Washington Libraries
Business names can be trademarked if the business provides a service, such as marketing, legal, accounting, etc. Business names, such as Ford Motor Company, Apple Computer, Advanced Micro Devices may be trademarked, but only if there are goods or services with that name.
- Ford is a registered trademark because it is the name of a company and a specific car
- Google is both a company name and a service.
The U.S. Trademark Office is very sticky about the difference between business names and product names. They have specific rules. It is a good idea to consult a book such as, Trademark: How to Name your Business & Product by Kate McGrath.
The following business directories are a good place to check for names that are already in use, thereby avoiding infringement.
