Description
Virtually all trademark owners and their counsel wrestle with the complex issue of likelihood of confusion. Understanding the different types of likely confusion is counsel's first step to avoid the pitfalls in pursuing or defending against trademark infringement claims.
Forward, reverse, initial interest, post-sale, and affiliation confusion are the five main types that counsel must understand and identify.
Intelligence from experienced trademark counsel can prepare practitioners to monitor their marks and identify and prove trademark infringement.
Listen as our authoritative panel of trademark attorneys examines the many types of trademark confusion, the challenges of each type, and the recent court treatment of the different types. The panel will offer best practices for applying the likelihood-of-confusion standard. Finally, the panel will also discuss how to defend against claims of trademark infringement.
