Docs derive their up to date information mainly from medical journals and from medical meetings...They are largely unaware of whether a medicine has a valid patent,or not, for the condition, for which the med is being prescribed....The same is true of local pharmacies...However, this is definitely NOT true in the case of generic companies, insurance companies, and PBMs...Docs writing on prescriptions the indication for which a med is being used...would go a long way help to minimize the multiple cases of patent infringement, made worse by skinny labels, which are clogging up court calendars.
