On expiry of the Invent Help invention idea license, common competitors would make use of the marketplace, which would certainly lead to reduction of market share and revenue loss for the innovator company. Thus, added patents are submitted in order to fencing the developed medication or product. These added licenses for the expansion of development/ product defense can comprise of technique of prep work, new formulation, method of preparation of solution, medication by-products and its metabolites, polymorphs, stereo-selective enantiomers etc. Additional licenses filed can also cover improvements to the invention or new usages, which are not mentioned in the initial provided patent.
