Jeffrey L. Costellia

Jeffrey Costellia heads up Nixon Peabody's IP Counseling & Transactions group and also chairs the firm's Global Strategies Committee. He represents both U.S. and foreign companies to develop overall, global intellectual property protection strategies involving all phases of patent and trademark prosecution and enforcement.

What do you focus on?

I focus my practice in three main areas, capitalizing on over 25 years of experience, to provide practical IP protection strategies that help clients meet or exceed their business objectives.

Tailored Patent Protection

I represent clients ranging from startups to Fortune 500 companies, helping them successfully navigate the ever-changing Patent Laws before the U.S. Patent and Trademark Office. I work closely with inventors and business managers to ensure that the patents I secure align with my client's business plans. I regularly review competitor patent validity and infringement issues and have helped clients obtain valuable patent rights covering electronic circuits, semiconductors, LCD and electroluminescent displays, chemical composites and polymers, locomotive and other transportation monitoring, photonics and sensing technologies and large scale product conveying equipment.

In-Depth Brand Protection

I work with clients to develop and protect their brand from initial product development through launch. I assist with mark selection, clearance, registration, and enforcement against third-party infringers. I tailor trademark protection strategies to fit my client's industry and global scope, whether it be for travel and entertainment services, cosmetics, transportation monitoring and sensing technologies, large scale product conveying equipment or sporting goods products and services.

IP Enforcement in the Federal Courts and Trademark Trial and Appeal Board

I have considerable experience in patent and trademark litigation in the United States federal courts and trademark cancellation and opposition proceedings before the Trademark Trial and Appeal Board. I develop comprehensive, broad-based intellectual property plans that give clients a greater return on investment.

What do you see on the horizon?

I foresee companies placing a greater emphasis on increasing the international scope of their IP protection and an increasingly competitive and global marketplace.
