Trademark vs. Patent

What It Means

Trademarks and patents are both forms of intellectual property, but they protect entirely different things and serve different purposes. A patent protects an invention — a new and useful process, machine, or composition of matter — for a limited time (20 years for utility patents). A trademark protects a brand identifier — a word, phrase, symbol, design, or combination that distinguishes one company's goods or services from another's — for as long as it continues to be used in commerce. The distinction matters because confusion between the two can lead to costly strategic mistakes. A pharmaceutical company might patent the molecular formula of a new drug (utility patent), patent the shape of the tablet (design patent), and trademark the brand name under which it is sold. When the patents expire, generic manufacturers can sell the same molecule, but they cannot use the trademarked brand name. This is why generic drugs are sold under their chemical names (e.g., atorvastatin) rather than the brand name (Lipitor). Trademark registration is handled by the USPTO's trademark division, which is separate from the patent examination corps. Trademarks can last indefinitely as long as the owner files renewal documents and continues to use the mark in commerce. Trademarks are also territorial, requiring separate registration in each country. Patent portfolios and trademark portfolios together form the core of a company's registered intellectual property assets. In portfolio analysis, patents are generally more relevant for competitive moats in technology and pharmaceuticals, while trademarks are more important for consumer products and services where brand recognition drives purchasing decisions.
