Domain name disputes have been a core practice area of the firm for over fifteen years, during which time we have represented clients in a wide variety of cybersquatting lawsuits and arbitrations. We thrive on the “difficult to win” cases, but also routinely use cybersquatting laws when managing our clients overall trademark portfolios.

“Cybersquatting” involves inserting another’s trademark into a domain name in bad faith.

Kronenberger Rosenfeld handles all forms of domain name disputes, including cybersquatting, “typo-squatting” and other domain-based trademark infringement. Our anti-cybersquatting lawyers also handle domain name theft (aka domain hijacking) and domain transfer fraud matters. Kronenberger Rosenfeld is a leader in domain name litigation, creating new Ninth Circuit law concerning the ability to seize domain names as property.

Litigating and arbitrating domain name disputes has been at the core of our practice for over 15 years.

There are two primary options if a third party has registered a domain name with your trademark, business name, or personal name.


The first option is to file a complaint with the Internet Corporation for Assigned Names and Numbers (ICANN) under its UDRP arbitration procedures and request that the domain be transferred to you. When a domain name is registered, the individual or business registering the domain name submits to mandatory arbitration in the event of a future dispute. UDRP arbitrations are substantially cheaper than federal litigation. Another advantage of UDRP arbitrations is that results can be obtained more quickly than in litigation (sometimes in 60 days). Kronenberger Rosenfeld handles many UDRP arbitration cases on a fixed fee basis. Click here for more on our experience with UDRP arbitrations.


The federal ACPA is a second option for trademark owners. Under the ACPA, trademark owners can seek not only transfer of the disputed domain but also monetary damages. Our firm has filed many lawsuits in federal court under this statute, including cybersquatting in rem cases filed against the domain name itself when there was no jurisdiction over the international domain name registrant.


If you feel that someone has registered a domain name (containing, say, your business or product name) and is competing against you unfairly, you may be able to assert your “common law trademark rights,” even though you have not registered your trademark with the federal government. Common law trademarks have been the basis for both UDRP arbitration complaints and complaints under the federal ACPA.
