Ranked among the top trademark firms by IP Today and the top 25 trademark opposition filing firms by Towergate Software, Fox Rothschild provides clients with comprehensive representation in the selection, search and registration of their marks. Our attorneys are well-versed and extensively experienced in proactively advising clients on issues related to the establishment, protection and, when needed, defense of trademark rights to help them manage and mitigate risk before problems arise. We have assisted clients with trademark availability opinions, preparation, renewal and prosecution of trademark registrations as well as trademark licensing and enforcement in the United States and abroad.

We also provide clients with strategic advice on building a strong house mark; developing a family of marks; adopting nontypical marks such as trade dress, color marks, sound marks or fanciful designs; building brand strength; helping with brand strategies; and obtaining related domain names or licensing the marks. For clients that actively market their brands on and engage in social media platforms, we assist with the selection and maintenance of appropriate domain names and advise on the use of a company's trademarks and brands on such social media outlets.


We help clients register, protect and license their copyrights. We also represent them in enforcement actions both domestically and internationally. Our services include assistance with:

  • Filing copyright applications with the U.S. Copyright Office to protect computer code
  • Software license and development agreements
  • Computer system acquisitions
  • Publisher-author and illustrator agreements
  • Internet hosting, web site development, design agreements and data-sharing agreements
  • Domain name acquisition and protection

Rights Management and Technology Transfer

We help clients exploit new technologies and business models by conducting IP audits to identify potential sources of revenue and assist in the development of plans to protect, maintain and manage rights in these sources. Our attorneys offer formal and informal opinions on such issues as patentability, product design and possible infringements of third-party intellectual property rights.

We also help clients establish policies and procedures and provide guidance to ensure trade secrets are maintained. We draft, enforce and, when necessary, litigate agreements involving nondisclosure and noncompete clauses.

Fox attorneys frequently provide legal analysis and counsel in the transfer of intellectual property rights in corporate transactions. We also evaluate the degree to which a purportedly protected asset could successfully withstand a legal challenge in local, state or federal court or the USPTO.

For clients in the private sector or at nonprofit organizations, we assist in the development of intellectual property and related policies and procedural safeguards designed to maximize and protect intellectual assets, obtain and enforce rights and address other related areas of concern.

Enforcement and Litigation

Our attorneys are familiar with the nuances of intellectual property litigation and possess decades of experience representing clients successfully in IP disputes in the courtroom, before administrative agencies, such as the Patent Trial and Appeal Board and the ITC, as well as arbitration panels and in settlement. We have resolved disputes involving patents, copyrights, trademarks, antitrust, unfair competition and related issues and have a particular knowledge of domain name arbitration and litigation. Among our successes, we recently won two separate eight-figure verdicts – both in the same year – in jury trials held in Pennsylvania and California.

We help clients analyze their IP portfolio to assess its suitability for meeting the company’s financial metrics and business plan. As the company grows, we serve as a trusted advisor and partner, assisting with licensing and portfolio management and continually assessing IP assets to strengthen and protect IP capital.
