Does my invention have commercial value?
If the product arising from your invention solves a current problem and meets a market need, you may have an invention with commercial value.
If you have developed something that might have wider use or could be more broadly applied, it could have commercial value.
The key to commercialization is the value proposition for an industry partner. An industry partner needs to recognize and accept that they can profit from selling a product based on your invention.
If an industry partner has already expressed interest in your work, that is a strong sign of commercial value.
