The biggest problem with product innovation is that most of it can be imitated and improved, their potential may be limited, or they may be highly risky because their potential is unproven. The new product has to be marketed to prove its potential. This may be acceptable for corporations since they have an existing business. All they have to do is to add the new product into their existing business model and supply chains, and use their existing marketing clout and resources to stay competitive. They don’t have to invest to create a new business around the product.
