A. Yes. A pharmaceutical product can be covered by several patents, up to 30 or 40, to protect it against competition for as long as possible. Even if the composition of matter (the basic patent on the new chemical entity and its molecular structure), has expired, originators can extend exclusivity by extending a medicine’s indications or developing new formulations.
