The Basics of Trademark Infringement

Trademark infringement is the unauthorized use of a trademark or service mark on or in connection with goods and/or services in a manner that is likely to cause confusion, deception, or mistake about the source of the goods and/or services. This includes the use of a mark that is identical or confusingly similar to an already existing trademark. As a result, trademark infringement can cause considerable damage to the reputation and economic value of the original trademark holder.

Here are a few Blue Book citations from case law that show how trademark infringement works:

  1. Hana Financial, Inc. v. Hana Bank, 675 F.3d 836 (9th Cir. 2012): In this case, the Ninth Circuit held that the defendant’s use of the “Hana” mark in connection with its banking services was likely to cause confusion with the plaintiff’s use of the same mark in connection with its financial services. The court found that the defendant’s use of the mark constituted trademark infringement.
  2. Tiffany (NJ) Inc. v. eBay Inc., 600 F.3d 93 (2d Cir. 2010): In this case, the Second Circuit held that the defendant’s sale of counterfeit Tiffany-branded goods on its website constituted trademark infringement. The court found that the defendant’s actions were likely to cause confusion about the source of the goods, and that the defendant was not protected by the “safe harbor” provisions of the Digital Millennium Copyright Act.
  3. New Kids on the Block v. News America Pub., Inc., 971 F.2d 302 (9th Cir. 1992): In this case, the Ninth Circuit held that the defendant’s use of the “New Kids on the Block” mark in connection with a crossword puzzle game constituted trademark infringement. The court found that the defendant’s use of the mark was likely to cause confusion with the plaintiff’s use of the same mark in connection with its musical group and merchandise.

These cases demonstrate that trademark infringement can occur when a party uses a mark in a way that is likely to cause confusion about the source of goods or services. It is important for businesses to protect their trademarks and to ensure that they are not infringing on the rights of others.

There are several reasons why it is important not to infringe on a trademark:

  1. Protecting the rights of the trademark owner: Trademarks are a form of intellectual property that are owned by a particular person or entity. When someone infringes on a trademark, they are using someone else’s property without permission, which can cause harm to the trademark owner’s reputation and financial interests.
  2. Avoiding legal liability: Infringing on a trademark can lead to legal action being taken against the infringing party. This can result in costly legal fees and damages, as well as the possibility of a court ordering the infringing party to stop using the trademark.
  3. Maintaining consumer trust and confidence: Trademarks are used to identify the source of goods and services. When consumers see a trademark, they trust that the goods or services are of a certain quality and come from a reliable source. If a trademark is infringed upon, it can cause confusion and mistrust among consumers, which can damage the reputation of both the trademark owner and the infringing party.
  4. Promoting fair competition: Trademarks help to distinguish one business from another and allow consumers to make informed choices about the goods and services they purchase. When someone infringes on a trademark, they may be unfairly competing with the trademark owner and potentially misleading consumers. This can create an uneven playing field and harm fair competition.

Overall, it is important to respect the rights of trademark owners and to avoid infringing on their trademarks in order to protect the interests of all parties involved and promote fair competition in the marketplace. Consumers benefit from trademark protection, as it gives them assurance that they are purchasing a product or service of a certain quality
