The Rubik Cube and freeriding

In 1974 Erno Rubik develops a 3D puzzle, a cube with 6 coloured surfaces. The mechanism is protected by a Hungarian patent. Each infringement of the invention can be prevented in this way, regardless of the print on its surfaces. Only after some years the cube becomes a success. Soon all kinds of varieties appear on the market, like the Sudoku Cube and the Kamasutra Cube. Rubik wants to act against these free riders, but how? The patent is already expired.

For this reason, he initiates actions claiming copyright. However is that possible, given the fact that the cube is a technical invention and therefore belongs in the regime of patents? The court sees the cube as an invention and judges the mere shape, without colours, is not worthy of copyright protection. The use of the contrasting colours on the surfaces however is copyright worthy. Therefore, cubes with similarly coloured surfaces are infringing the Rubik Cube and should be destroyed. However, the Kamasutra Cube and the Sudoku Cube give a sufficiently different overall impression and are allowed.

IP quiz Trademarks

Puma is one of the bigger sports and lifestyle brands in the world. The core-business is the design, development and sale of (sports) shoes, (sports) clothing and accessories. In 1960, Puma registered an international trademark for a device designed in 1958: the formstrip. Since then, Puma has registered approximately 90 formstrip trademarks with validity in the Benelux or the European Union. Puma claims that this is a serial mark. Monshoe is a wholesaler of women's shoes and related products. The company designs and develops Monshoe shoes which it largely markets itself. Monshoe sells its women's shoes under the brands Shoecolate and Pearlz. The shoe Shoecolate is offered in various colour combinations. Puma claims that Monshoe infringes its well-known formstrip trademark. Monshoe contradicts this and states that the average consumer will not perceive the device of Monshoe on the sneakers as a trademark. And if the public will recognize a trademark in the decoration, it will not make the connection to Puma. According to Monshoe, the formstrip logo is not a well-known trademark within the meaning of the BVIE and the UMVo. There is no likelihood of confusion because the sign does not or hardly evoke any association with Puma among the public. In light of the above, who is right? Does this constitute decorative use or linking to a well-known trademark?
