Rubik's Cube: When a Shape Trademark Failed

The Rubik's Cube shape trademark failed because courts ruled its rotating-grid mechanism is a functional, technical solution — not a brand signifier. Under Nepal's Patent, Design and Trade Mark Act 1965, administered by the Department of Industry, a shape that achieves a technical result cannot be monopolised as a trademark, no matter how iconic the object becomes.

Key Takeaways

• The Rubik's Cube's 3×3×3 grid was denied trademark protection in Europe because its shape achieves a technical function — rotation.
• Nepal's Patent, Design and Trade Mark Act 1965 does not explicitly define shape marks, but the DoI applies functionality and distinctiveness tests.
• A shape that gives a product substantial value or performs a technical function cannot be a registered trade mark in most jurisdictions, including Nepal.
• In Nepal, rights come from registration only — it's a first-to-file system, so filing early matters.
• If your shape is merely decorative and distinctive, a 3D trademark or an industrial design registration might protect it instead.

What is a shape trademark, and why did Rubik's Cube try to register one?

A shape trademark — often called a 3D mark — protects the three-dimensional form of a product or its packaging, so long as that shape tells consumers who made it. Think of the Coca-Cola contour bottle. Seven Towns, the UK company that manages Rubik's Cube IP, applied to register the cube's black-grid-on-coloured-faces shape as an EU trademark in 1996. It was granted — then challenged. The argument was simple: the cube's grid is not a brand sign. It's the puzzle itself.

What did the European Court of Justice actually decide?

In November 2019, the Court of Justice of the European Union delivered the final blow. It ruled the Rubik's Cube shape trademark invalid because the shape is necessary to obtain a technical result — the rotation of the rows and columns. EU trade mark law excludes signs that consist exclusively of a shape that performs a technical function. The court was clear: the grid lines are not arbitrary decoration; they create the mechanical possibility of the puzzle. That is the domain of patent law or industrial design, not trademark.

How does Nepal treat shape and 3D marks?

The Patent, Design and Trade Mark Act 1965 defines a trade mark as a "word, symbol, or picture or a combination thereof." It does not explicitly mention three-dimensional or shape marks. However, in practice the Department of Industry accepts applications for distinctive product and packaging shapes as trademarks, provided they can be represented graphically. A shape that performs a technical function or adds substantial value to the goods — exactly the Rubik's Cube scenario — would face refusal at the examination stage, consistent with international norms under the Paris Convention and TRIPS, which Nepal follows.

What is the difference between a shape trademark and an industrial design?

This is the heart of the Rubik's Cube lesson. A shape trademark protects the form as a badge of origin — it tells you who made the product. An industrial design protects the form as an aesthetic or visual feature — it stops others from copying the look. In Nepal, industrial designs are registered under the same 1965 Act but via a separate process, with a renewable 5-year term. If your shape is new, ornamental, and non-functional, an industrial design filing is often the correct tool. If you try to register a functional shape as a trademark, the DoI will likely object — the same principle that killed the Rubik's Cube mark in Europe.

How do you register a non-functional shape mark in Nepal?

While no shape-mark case has been litigated to Nepal's Supreme Court, the DoI applies a standard examination process. Here is how a distinctive, non-functional 3D mark would be filed:

1. Confirm the shape is non-functional. If the shape gives a technical advantage or is essential to how the product works, it belongs in a patent or design application, not a trademark.
2. Conduct a trademark search. Use IP Sewa's trademark database search to check for conflicting registered marks, including any existing 3D or device marks in your class.
3. Identify the correct NICE class. A 3D product shape is filed in the goods class the product belongs to — use the NICE class finder to be certain.
4. Prepare graphical representations. You need clear line drawings or photographs showing every angle of the shape — typically six views (front, back, left, right, top, bottom) plus a perspective view.
5. File the application at the DoI. Submit the Schedule 1(c) form with four specimens of the mark, pay the government fees, and receive your acknowledgment number.
6. Examination and publication. The DoI examines for distinctiveness and conflicts. If approved, the mark publishes in the Industrial Property Bulletin for a 90-day opposition window.
7. Registration certificate. If unopposed, pay the registration fee and receive your certificate. The term is 7 years, renewable indefinitely.

What makes a shape registrable — and what kills it?

Courts worldwide have settled on three tests. A shape cannot be a trademark if it (a) results from the nature of the goods themselves, (b) is necessary to obtain a technical result, or (c) gives substantial value to the goods. The Rubik's Cube failed on (b) and (c). In Nepal, the DoI's examination under Sec. 18 of the Act mirrors these principles — a mark that damages another's goodwill or is not inherently distinctive won't proceed. A common mistake we see is a business spending heavily on packaging only to find the shape is too generic or functional to protect.

Could Rubik's Cube have protected its shape another way in Nepal?

It did — just not with a trademark. The original Rubik's Cube mechanism was protected by a patent (filed in Hungary in 1975). That patent expired long ago, which is why you see lookalike cubes everywhere. In Nepal, a novel puzzle mechanism could be filed as a patent registration through the DoI, with a 7-year renewable term. The visual design — the specific coloured stickers or surface ornamentation — might qualify as an industrial design if new. But the 3×3 grid itself was always going to be a trademark dead end.

What is the legal basis for rejecting functional shapes in Nepal?

The Patent, Design and Trade Mark Act 1965, Sec. 18, instructs the Department to refuse marks that damage another's goodwill or are already registered. While the Act does not spell out a "functionality doctrine" word for word, Nepal's obligations under the Paris Convention and TRIPS — and the DoI's examination practice — incorporate the principle that technical or functional shapes cannot be monopolised as trademarks. A shape that is essential to how a product works belongs in the patent or design chapters of the Act, not the trademark chapter. The Trademark Directives, 2072 BS, further guide DoI practice on distinctiveness and registrability.

What should a Nepali business learn from the Rubik's Cube case?

Don't assume your product's shape is a trademark. If the shape makes the product work, you need a patent. If the shape makes it look good, you need a design. If the shape — and only the shape — tells a consumer it's your brand, then a trademark might fit. A realistic Nepal example: suppose a Thamel handicraft exporter designs a distinctive triangular singing-bowl cushion with a unique folded-corner profile. The folding function itself is not trademarkable. But if the overall cushion silhouette is purely decorative and consumers recognise it as that exporter's signature, a 3D shape mark could work.

In short

The Rubik's Cube shape trademark failed because the law draws a hard line between "this is how it works" and "this is who made it." Nepal's Department of Industry enforces that same line. If you have a distinctive, non-functional product shape that you want to own exclusively, a shape trademark or industrial design filing might be your answer — but you need to get the classification and the drawings right, and you need to act before someone else files first.
