I'm not sure of what your question applies. But taking it in such a way I would like to point here my suggestions of what I have understood from the question. - Marketing strategy doesn't intend in the creation of new products. Moreover, marketing strategy has been structured in gaining a better visibility to the new products (*completely a reverse procedure). Applying a better marketing technique will bring in a better result for the product, in which the users will suppose to be your customers after. It models your business product to the fame and thus, it lets the users to have a try with your product. This in turn will aid you to experience the growth in ROI of your business :)

A new product, or a major improvement to an existing product, is called an invention.An invention strategy is a summary of your idea that tells the world what it is, why they need it and how your invention is superior to other products.
