The 13.1.2.3 Infringement - Elements - Likelihood Of Confusion - Factor form provides official jury instructions for assessing trademark infringement based on the likelihood of confusion. This form, adopted by the Federal 7th Circuit Court, guides jurors in determining whether the use of a mark by a defendant may mislead consumers regarding the origin or sponsorship of the products involved. It is distinct in that it emphasizes various factors that influence consumer confusion, setting it apart from other legal instructions related to trademark disputes.
This form should be used in legal cases where a plaintiff alleges trademark infringement based on a likelihood of confusion.
