An enforceable Patent is a key to effective Commercialization of any technology. Even in case of good technology, if the description of the technical subject matter is not enabling or fails to disclose all necessary embodiments, and if in case of any claims that are narrowly drafted and do not gain support from the specification, in such a case technology’s worth is insignificant.
