Accused Businesses
Defense strategy for demand letters, complaints, takedowns, launch threats, and overbroad infringement claims.
Online Marketplace Conflicts
Disputes involving search ads, listings, takedowns, reseller pages, sponsored results, and competing online uses.

Early litigation choices should connect the legal position to the commercial pressure creating the dispute.
Confusion Evidence
Customer messages, marketplace presentation, search results, packaging, sales-channel overlap, and buyer sophistication.
