What do you focus on?

Brands and Creations

I counsel clients to mitigate their risks and maximize the value of their global IP in a wide range of industries including sports, media and entertainment, fashion, computer software, financial services, medicine and biotechnology. My work includes all aspects of intellectual property counsel and enforcement—from selecting, clearing and registering trademarks and copyrights to enforcing and defending rights.

My clients know me best for understanding the intricacies of their businesses and developing unique and cost-effective solutions to complex problems.


I am a registered patent attorney with years of experience in drafting and prosecuting patent applications in technologies ranging from sports to biotechnology. My experience as a patent attorney allows me to understand and advise clients on all aspects of intellectual property, thereby developing comprehensive and cost-effective solutions.

Intellectual Property Enforcement

An important aspect of developing and maintaining IP assets is ensuring that the exclusivity provided in established rights are maintained and not misappropriated. I routinely represent clients in enforcing and defending their IP rights in proceedings, including appearances in numerous U.S. federal courts, and before the U.S. Trademark Trial and Appeal Board and World Intellectual Property Organization. I have an established record of successfully resolving matters to my clients’ satisfaction.

What do you see on the horizon?

Intellectual property owners are constantly having to properly identify and protect their assets against misappropriation and counterfeiting. In today’s global economy it will be more important than ever for companies to understand the nuances and differences in laws from one jurisdiction to another to suitably develop and commercialize their portfolios.
