Functionality Doctrine: Key Insights into Trademark Law

Definition & Meaning

The functionality doctrine is a legal principle that states that certain features of a trademark, particularly those that serve a functional purpose, are not eligible for trademark protection. This means that if a trademarked element, such as a shape, color, or design, is essential for the product's performance or marketability, it cannot be trademarked. The rationale behind this doctrine is to ensure fair competition in the market, allowing new entrants to use features that consumers find desirable without infringing on existing trademarks.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A company designs a specific shape for a kitchen appliance that improves its efficiency. This shape may not be trademarked because it is functional.

Example 2: A beverage company uses a unique bottle color that enhances visibility on shelves. If this color is essential for the product's appeal, it may not qualify for trademark protection. (hypothetical example)
