Intellectual Property

“Approximately 70  percent of the value of publicly traded corporations comes from intangible assets.”

- Economic Report of the President to the Congress, February 2006

Intellectual property is the central asset of American businesses today. More than 17 percent of total U.S. economic activity was driven by intellectual property industries in 2003, while studies suggest that trademarks and branding potentially represent the single most valuable asset of many firms.  The attorneys in DMOC’s Intellectual Property Department are positioned to offer full service representation encompassing both traditional intellectual property practice and cutting edge applications of the law.

A trademark can embody many things – the promise of quality, an indication of source, and the backing of a company whose reputation has been built through years of dedication. These intangible qualities are an immensely valuable asset.

False Advertising

Competition laws are in place to protect the economic, creative and intellectual investments made by businesses in distinguishing themselves and their products. Businesses that utilizes unfair, deceptive and misleading practices may cause competitors substantial, and sometimes irreparable, harm. Federal and state law prohibit false advertising, which involves the promotion of goods, services or commercial activities that misrepresents their nature, characteristics, qualities or geographic origin. Similarly, unfair competition consists of any commercial behavior or activity that is legally unjust or deceptive, and may include activities such as false advertising, trademark and trade dress infringement and theft of trade secrets. DMOC attorneys are well versed in all aspects of laws related to advertising, marketing, unfair competition and misleading or deceptive trade practices.  We provide counseling and litigation services to clients in these areas, which require compliance with complex federal and state authority, including the Lanham Act, the Federal Trade Commission Act and state statutes and common law.  We represent clients in false advertising and unfair competition matters across all types of media, including print, television and internet. Our attorneys also handle injunction proceedings on behalf of trademark holders to cease and prevent the sale of counterfeit goods and materially different goods.

Patent Litigation

Patent rights are a powerful form of intellectual property. If your patent is being infringed, our experienced attorneys can help you enforce your rights in federal court. If you or your business is accused of infringement, defending yourself is critical, because infringement suits are often accompanied by the threat of an injunction potentially shutting down your business at the outset of the suit.


According to the Federal Trade Commission, free and open markets are the foundation of a vibrant economy, and aggressive competition among sellers in an open marketplace gives consumers the benefits of lower prices, higher quality products and services, more choices, and greater innovation. Antitrust laws,  which apply to both businesses and individuals, prohibit anti-competitive behavior, monopolies and unfair business practices. While antitrust laws are intended to encourage competition in the marketplace, intellectual property rights provide patent, copyright and trademark owners with exclusive rights in their creations. DMOC attorneys have a deep understanding of this complex intersection, and regularly counsel clients in a broad range of industries, including eCommerce, retailing, consumer products, financial services, media, telecommunications and many others. DMOC attorneys also represent companies, and their officers and directors, in antitrust and intellectual property matters in federal and state courts and before various agencies.
