Brand dilution expert witness candidates typically have expertise in marketing, brand management, consumer surveys, consumer behavior, trademark confusion, trademark law, and/or brand equity.

Brand dilution occurs when consumers no longer associate a brand with a specific product. Dilution by blurring occurs when a famous mark’s distinctiveness is devalued by association with another similar mark or trade name. Dilution by tarnishment occurs when a famous mark’s reputation is devalued through its association with another similar mark. The Federal Trademark Dilution Act (FTDA) protects famous marks from unauthorized use and attempts to prevent dilution of its distinctiveness. Almost every trademark infringement dispute revolves around whether a consumer would encounter actual confusion by the potentially infringing similar mark. A consumer confusion survey can help owners understand if there is brand or trademark dilution. Consumer survey research is commonly used to prove or disprove trademark infringement or likelihood of confusion, and survey evidence and methodology can be used as court evidence in a trademark litigation case.

Brand dilution cases that Cahn Litigation Services locates expert witnesses typically surround intellectual property law issues such as trademark protection, trademark abandonment, unfair competition, business valuation, deceptive advertising, copyright infringement, false advertising, trademark dilution, trade dress infringement, brand distinctiveness/secondary meaning, and trademark surveys. Litigation support by a brand dilution expert witness expert witness could include marketing research, survey research, expert report preparation, and/or expert testimony on consumer survey and consumer confusion.
