Most pharmaceutical companies will file a number of patents on any given medicine, to protect it against competition for as long as possible. Examples of patents are: composition of matter (the basic patent on the new chemical entity and its molecular structure), method of use (the process by which the medicine acts in the body), formulation (how the medicine is designed to enter the body, reach relevant organs and achieve the required effect).
