15.4 TRADEMARK LIABILITY—THEORIES AND POLICIES (15 U.S.C. §§ 1114(1), 1125(a))
The trademark laws balance three often-conflicting goals: 1) protecting the public from being misled about the nature and source of goods and services, so that the consumer is not confused or misled in the market; 2) protecting the rights of a business to identify itself to the public and its reputation in offering goods and services to the public; and 3) protecting the public interest in fair competition in the market.
The balance of these policy objectives vary from case to case, because they may often conflict. Accordingly, each case must be decided by examining its specific facts and circumstances, of which you are to judge.
In my instructions, I will identify types of facts you are to consider in deciding if the defendant is liable to the plaintiff for violating the trademark law. These facts are relevant to whether the defendant is liable for:
[1. infringing plaintiff’s registered trademark rights, by using a trademark in a manner likely to cause confusion among consumers][;]
[2. unfairly competing, by using a trademark in a manner likely to cause confusion as to the origin or quality of plaintiff’s goods] [;]
[3. unfairly competing, by using trade dress in a manner likely to cause confusion as to the origin or quality of plaintiff’s goods] [;]
[4. infringing plaintiff’s trade name, by using similar corporate, business or professional names in a manner likely to cause confusion about the source of products in the minds of consumers] [;] [and]
[5. false advertising, by making a false statement that was material and that tended to deceive consumers, injuring the plaintiff in the market].
"The limited purpose of trademark protections set forth in the Lanham Trade-Mark Act, is to ‘avoid confusion in the marketplace’ by allowing a trademark owner to ‘prevent[ ] others from duping consumers into buying a product they mistakenly believe is sponsored by the trademark owner.’" Mattel, Inc. v. Walking Mountain Productions, 353 F.3d 792, 806–07 (9th Cir.2003) ("Generally, to assess whether a defendant has infringed on a plaintiff’s trademark, we apply a ‘likelihood of confusion’ test that asks whether use of the plaintiff’s trademark by the defendant is ‘likely to cause confusion or to cause mistake, or to deceive as to the affiliation, connection, or association’ of the two products.") (citations omitted). Federal trademark law addresses "the dual purposes of infringement law: ensuring that owners of trademarks can benefit from the goodwill associated with their marks and that consumers can distinguish among competing producers." Thane Int’l v. Trek Bicycle Corp., 305 F.3d 894, 900–01 (9th Cir.2002).
The general test of liability under the trademark law is likelihood of confusion. See 15 U.S.C. §§ 1114(1), 1125(a). "[T]he ultimate test is whether the public is likely to be deceived or confused by the similarity of the marks.... Whether we call the violation infringement, unfair competition or false designation of origin, the test is identical–is there a ‘likelihood of confusion?’" New West Corp. v. NYM Co. of California, Inc., 595 F.2d 1194, 1201 (9th Cir.1997).
Generally, liability for infringement of a registered trademark is handled under 15 U.S.C. § 1114(1). Unfair competition through infringing an unregistered trademark or infringing trade dress is handled under 15 U.S. C. § 1125(a). A cause of action for false advertising is also found in 15 U.S.C. § 1125(a). See Harper House Inc. v. Thomas Nelson, Inc., 889 F.2d 197 (9th Cir.1989); U-Haul Int’l v. Jartran, Inc., 601 F.Supp. 1140 (D. Ariz. 1984), aff’d in part, modified in part & rev’d in part, 793 F.2d 1034 (9th Cir.1986). Elements required for a false advertising claim, cognizable under 15 U.S.C. § 1125(a)(1)(B), are set forth in Rice v. Fox Broadcasting Co., 330 F.3d 1170, 1180 (9th Cir.2003).
