In addition to time-limited patent protection, can indefinite trade mark protection be sought for the product shape of the Global Yoshikin knives?
Your product has an extraordinary design and a special technical function. The Gömbök is such a product. Is trade mark protection for such products easy to achieve?
The patent of your product has expired. And the trade mark that protected its shape has been cancelled. But don’t give up. You may still be able to claim protection against counterfeiting.
Have you registered the shape of a technically sophisticated product, such as the Rubik’s Cube, as a trade mark? Then check again whether the trade mark is really protectable.
