Dear product designers, We'd like to develop two products, but could'nt find anything in a more detailed web search on this topic. Our point is that we want to develop a product designed for the Apple Pencil and a product designed for Nintendo DS consoles, but we do not know what it is about licensing or anything like that. Also, what about gadgets for smartwatches or cell phone mounts or charging stations? Could you possibly help us further? Do we have to pay licensing fees to one of the big companies? Kind regards Florian Meise from manugoo
