> he called himself Legoheld and then he tried to trademark that name can you give any citation for that? Because i can find zero sources for that claim. Sources for the conflict around the logo design are ample, see his filing for the logo (1) and the one from the corporation (2). I can find no filing for your claim about the name in the official database and no media reports supporting it anywhere, only that in 2013, years before the first conflict with the corporation, his brand was already established as "Held der Steine".(3) 1: https://register.dpma.de/DPMAregister/marke/register/3020182151470/DE?lang=en https://register.dpma.de/DPMAregister/marke/register/3020182... 2: https://register.dpma.de/DPMAregister/marke/registerHABM?AKZ=007453657&lang=en https://register.dpma.de/DPMAregister/marke/registerHABM?AKZ... 3: https://www.welt.de/regionales/frankfurt/article121164920/Verspielte-Erfolgsstory-eines-Kleinunternehmers.html https://www.welt.de/regionales/frankfurt/article121164920/Ve... > if his trademark claim had succeeded, Lego would have lost theirs. no. The marks would be seen as reasonably different. As others have noted the corporations ability to sue in similar cases might be reduced if they create a history of tolerating such "reasonably different" marks, but they would not have lost their design trademark, especially because theirs is a 3D design mark and his was word+logo mark and they are filed for different things. I personally think his mark would have had little to no effect on theirs and he might have had an actual chance of winning in court, albeit a phyrric victory. He cancelled his filing and filed the same name with a different image. For the whole "invalidating of design patents" there is a far more interesting case that has nothing to do with him: Delta Sport Handelskontor GmbH vs LEGO A/S where the former tried to have EU design patent 001664368-0006 invalidated so they can print and sell the exact same plastic piece under the PLAYTIVE® brand on the market. They lost in court during appeal.
