Trademarks

Questions about whether two marks are confusingly similar often involve far more than a side-by-side comparison. A trademark expert witness can examine how names, logos, symbols, packaging, or trade dress appear and function in the marketplace, using evidence such as trademark records, advertising and sales materials, product presentation, consumer survey data, and information about the parties' goods, services, customers, and competitive environment.

This analysis may be relevant in disputes involving trademark infringement, likelihood of confusion, trademark dilution, trade dress, or cybersquatting. Depending on the expert's qualifications and the issues in the case, the expert may compare marks in appearance, sound, meaning, and overall commercial impression, evaluate marketplace conditions and channels of trade, or assess consumer-perception evidence. These findings can help counsel evaluate the factual basis for confusion or dilution claims and explain how consumers encounter and perceive the disputed marks in the marketplace.
