Nikon Rumors posted an English translation via an AI recap of the 25-page document, which helps to shed some light on the Chinese authority’s reasoning, stating that the legal basis for the invalidation was a “lack of inventiveness”.

What does that mean? Well, according to Strachan IP, a patented invention has to “have at least one novel technical feature over what has been done before,” which is called an inventive step. So, you can’t patent a wheel, but you can patent a particularly innovative axle.

In the aforementioned court case, the CNIPA has invalidated Nikon’s patent by arguing that it simply isn’t inventive enough. The story continues…
