However, the specific product(s) implicated in the lawsuit remains unclear. Nikon Rumors translated a 25-page document into English using an AI, providing insights into the Chinese authority's rationale, which cited \"lack of inventiveness\" as the basis for the patent's invalidation. According to Strachan IP, an invention needs at least one novel technical feature over existing ones, known as an inventive step. Thus, a wheel can't be patented, but an innovative axle can. In the aforementioned legal case, the CNIPA invalidated Nikon's patent by asserting that it lacked sufficient inventiveness. The narrative continues...",
