Yes, you can trademark a product’s shape, but it falls under a specific category called trade dress and faces a higher bar than a word or logo mark. The shape must be non-functional, and product design cannot be treated as automatically distinctive — it always has to earn distinctiveness through consumer recognition before it can register.
Trade dress protects the visual appearance of a product when that appearance identifies who makes it, similar to how a logo does. For product shape specifically, this means the design of the item itself — not its container or wrapper. The Hershey’s Kiss is a well-known example: the shape of the chocolate itself is registered trade dress, distinct from any packaging it comes in.
Under long-standing Supreme Court precedent, product design — meaning the shape of the product itself — can never be treated as inherently distinctive, no matter how unique it looks. It must earn distinctiveness through what’s legally known as secondary meaning, typically shown through evidence like years of consistent use, sales figures, and advertising investment. This is a firm rule with no shortcuts, which is part of why shape trademarks take real time and evidence to build.
Even a highly distinctive shape can’t be trademarked if it’s functional, meaning the shape is essential to how the product works or affects its cost or quality. Functional features are typically protected through utility patents, not trademarks, if at all. This distinction between shape-as-branding and shape-as-function is often the deciding factor in whether a design mark can register.
How is trademarking a product shape different from trademarking a logo?
A logo can often be registered as soon as it’s used in commerce. A product shape can’t — it has to prove distinctiveness through consumer recognition first, since shape alone isn’t assumed to signal a brand the way a logo is.
Can a functional shape ever be trademarked?
Generally, no. If a shape is essential to how the product works or affects its cost or quality, it’s considered functional and can’t be protected as a trademark, regardless of how distinctive it looks.
How long does it take to build enough recognition to trademark a shape?
There’s no fixed timeline. It depends on factors like how consistently the shape has been used, how much has been invested in marketing it, and whether evidence like consumer surveys supports the connection to your brand.
Is product packaging treated the same way as product shape?
Not exactly. Packaging can sometimes be considered distinctive right away, without the same lengthy proof requirement, because consumers tend to read packaging as a brand signal more readily than a product’s shape itself.
Does trade dress cover anything besides product shape?
Yes. Trade dress is a broader category that can also include packaging, color, and even flavor, each judged by its own distinctiveness standard. Packaging, for example, can sometimes be considered distinctive right away, without the lengthy proof requirement that product shape needs.
Thinking about protecting a distinctive product shape? A comprehensive trademark search can show how your design compares to what’s already registered or in use, so you know where you stand before investing in the evidence it takes to register it.
