Counterfeit & Online Infringement in California

Focused counterfeit & online infringement representation by Sari Law Firm. Part of our Intellectual Property practice. Free consultation, transparent pricing, and clear communication at every step.

What is Counterfeit & Online Infringement?

Counterfeit and online infringement enforcement targets unauthorized sellers using your trademark on online marketplaces, social media, e-commerce stores, and counterfeit goods imported from overseas. The enforcement toolkit includes marketplace takedowns, customs recordation, John Doe lawsuits, asset freezes, and seizure orders.

When you might need this service

  • Your products are being counterfeited or your mark is appearing on knock-off goods online.
  • A marketplace seller is using your mark on listings of products that compete with or counterfeit yours.
  • Customs has stopped a shipment under your trademark recordation and needs response and follow-through.
  • A series of small infringers are appearing across multiple marketplaces and you need a coordinated enforcement strategy.

How Sari Law Firm helps

We file marketplace takedown notices (Amazon Brand Registry, Shopify, Meta, TikTok Shop, eBay), record your trademarks with U.S. Customs and Border Protection, pursue John Doe lawsuits against anonymous sellers, and seek seizure orders and asset freezes in federal court. For brands with ongoing counterfeit problems we build a sustained enforcement program rather than one-off takedowns.
