Trademarks & Copyrights

We help clients strategically grow their businesses and maintain their positions in the marketplace by developing, protecting and monetizing well-known and distinctive brands.

Our Approach

The growth of social media marketing and online business transactions has further motivated companies to safeguard their trademarks, register their works and defend their brands. Our attorneys utilize a forward-thinking approach, unique strategies and flexible budgets to represent established companies, early-stage companies, innovators and artists on a variety of trademark and copyright issues.

With first-hand experience working in business, our attorneys understand how to navigate the obstacles that inhibit successful brand management and global enforcement programs—even before launching a mark.

We provide counsel on issues involving advertising and promotions, right of publicity and domain names. With significant experience in proceedings under the Uniform Domain-Name Dispute-Resolution Policy (UDRP), we handle name acquisitions, online monitoring for unauthorized registrations, strategic portfolio assessments and recovery of domain names from infringers. We devise innovative methods for protecting, monitoring and enforcing our clients’ copyright-eligible work in the traditional and digital world.
