Commercial gain of a product from the expense of research and development, and the financial return during its life, is known as technology life-cycle. Some technologies have a long life span, whereas others have relatively short life spans. Steel and paper are two technologies which have relatability long life spans. Electronics and pharmaceuticals, on the other hand, experience frequent changes and this makes their general lifespan quite short. The main concern here is time and cost expended in developing the technology, and, of course, with the timelines for recovering all these costs so as to ensure that the investments are well worth and yield profits as a natural course. The patents and trademarks follow to lengthen the technology's lift-cycle and maximize the profit yield.
