What indicates "commercial exploitation" of an invention?

The indication of "commercial exploitation" of an invention primarily relates to activities that demonstrate the inventor's intent to capitalize on their invention. This can include actions such as marketing efforts, negotiations with potential buyers or licensees, and other tangible steps taken toward commercialization. When an inventor showcases a clear intention to bring an invention to market, it signals commercial exploitation.

While other choices might relate to the invention in various contexts, they do not directly express the intent of the inventor in a way that reflects commercial exploitation. Prior art publications might establish the prior state of knowledge but do not imply commercialization. Patent filings can suggest an inventor’s efforts towards protection but are not definitive proof of commercial activity. Public demonstrations, while they might suggest an effort to showcase the invention, do not necessarily indicate a structured approach to commercial exploitation unless accompanied by clear marketing or sales intent. Therefore, the intent of the inventor is the most direct and relevant indicator of commercial exploitation.
