INTELLECTUAL PROPERTY
Clerkin, Sinclair & Mahfouz combines extensive experience in trademark, copyright, and patent law to effectively meet client objectives.
 
TRADEMARKS
We prepare and file trademark applications before the U.S. Patent and Trademark Office, draft licensing agreements, and represent clients in litigation before the Trademark Trial and Appeal Board and federal courts. Our firm also assists clients in securing and enforcing trademark rights in other countries, as well as obtaining protection from the U.S. Customs Service against infringing imports. Additionally, we have significant experience litigating claims under the Lanham Act's false advertising and misrepresentation provisions. 

We advise clients on strategies to prevent and address unauthorized uses of trademarks in domain names and on third-party websites. In this context, we monitor and provide guidance on new trademark laws and infringement theories that could be effective in combating online trademark infringement.

 
COPYRIGHTS
The rapid growth of digital media and information-based industries has heightened the importance of copyright as a vital form of legal protection for products, services, and competitive strategies. We provide comprehensive copyright advice in both litigation and transactional counseling. In litigation, our firm has extensive experience in prosecuting, defending, and settling significant copyright infringement claims. In transactional matters, we manage complex issues related to copyright creation, ownership, and licensing.

Regarding patents, we collaborate with U.S. Patent and Trademark Office-registered attorneys and agents to offer patent prosecution and filing services for our clients. This partnership enables us to deliver high-quality patent prosecution services in a cost-effective manner. Our attorneys also have broad experience in prosecuting, defending, and settling patent infringement claims, and we handle complex patent licensing issues in transactional matters. 

 
LICENSING
We are actively engaged in the global licensing of technology and intellectual property. Our legal team has drafted, negotiated, and reviewed licensing agreements for patents, trademarks, and copyrights to ensure compliance with the specific regulations in the United States and other countries. We have extensive experience in licensing various technology sectors.
 
LITIGATION
We handle a diverse array of intellectual property matters nationwide. Our expertise includes both the prosecution and defense of actions related to patent, copyright, and trademark infringement. We also have extensive experience in false advertising litigation under the Lanham Act and in internet litigation. Our firm is particularly skilled in representing high-tech companies in intellectual property litigation.
