Can CarFax Sue Me for Naming My Brand “PersonFax”?

Question from Jow, Can CarFax Sue Me for Naming My Brand “PersonFax”?

Answer from AI:

When considering naming a new brand, it’s important to be aware of trademark laws and the potential for infringement. In the United States, trademark law is governed by the Lanham Act, which protects brand names, logos, and other identifiers from being used in a way that could cause confusion among consumers or dilute the distinctiveness of an existing trademark.

Understanding Trademark Infringement

Trademark infringement occurs when a mark that is the same or confusingly similar to a registered trademark is used in a way that could cause confusion about the source of goods or services. To determine if infringement has occurred, courts generally consider several factors, including:

  • The similarity of the marks in appearance, sound, and meaning.
  • The similarity of the products or services offered under the marks.
  • The likelihood of consumer confusion.
  • The intent of the alleged infringer in selecting the mark.

Potential Legal Risks with “PersonFax”

Using the name “PersonFax” for a brand that checks people before dealing with them could potentially raise legal issues if CarFax believes that such use infringes on their trademark. CarFax could argue that “PersonFax” is confusingly similar to their brand, especially if the services offered under “PersonFax” are somewhat related to the vehicle history reports provided by CarFax.

Trademark Dilution

Even if there is no direct competition or likelihood of confusion, CarFax might claim trademark dilution. Dilution occurs when a mark similar to a famous trademark blurs its distinctiveness or tarnishes its reputation. The use of “PersonFax” could be seen as diluting the CarFax brand, especially if “CarFax” is considered a famous mark.

Defenses and Considerations

If CarFax were to take legal action, you might have defenses available, such as arguing that there is no likelihood of confusion or that the services are not related. However, these defenses can be complex and require a thorough legal analysis.

Seeking Legal Advice

It is highly recommended to consult with a trademark attorney before moving forward with the “PersonFax” brand. An attorney can help you:

  • Conduct a comprehensive trademark search to assess the risks of infringement.
  • Advise on the likelihood of a successful trademark registration for “PersonFax”.
  • Provide guidance on how to avoid potential legal issues with CarFax or other trademark holders.

Alternative Actions

To minimize legal risks, consider:

  • Choosing a brand name that is distinctive and not similar to existing trademarks.
  • Creating a unique logo and branding strategy that differentiates your service from others.


While there is a chance that CarFax could take legal action against the use of “PersonFax,” the outcome would depend on various factors, including the specifics of your service and how the name is used in the marketplace. To avoid potential legal issues, it’s best to seek professional legal advice and consider alternative branding strategies.
