Sears-Compco Doctrine: Key Insights into State and Federal Law

Definition & Meaning

The Sears-Compco doctrine is a legal principle that addresses how state laws can protect designs and ideas that are not patented or registered but are in the public domain. This doctrine suggests that if state law restricts the public's ability to use these unprotected designs, federal law may override that state law, preventing such protection. This principle is particularly relevant in cases involving trade dress, which refers to the visual appearance of a product or its packaging that signifies the source of the product. The doctrine is rooted in two key Supreme Court cases: Sears, Roebuck & Co. v. Stiffel Co. and Compco Corp. v. Day-Brite Lighting, Inc., both decided in 1964.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A company designs a unique lamp that is not patented. If a state law tries to prevent other companies from making similar lamps, that law may be challenged under the Sears-Compco doctrine, as it could impede public access to unprotected designs.

Example 2: A restaurant uses a specific color scheme and layout that is not registered as a trademark. If another restaurant adopts a similar look, the original restaurant may have limited recourse under state law due to the Sears-Compco doctrine. (hypothetical example)
