Evergreening- Just think of it as a company discovering that changing a substituent will make the medicine 10percent cheaper, so they patent the new formulation. This means even when the original patent expires, they will continue to hold the cheaper medicine patent for an x amount of years extra
Compulsory license- Since, we are a poor country not everyone can afford medicine costing 1L. The govt. very rarely brings down the prices by compulsory license. This is also done in Brazil. Now, this is done quite rarely otherwise companies might not want to sell their products here.
Can someone explain evergreening of patent and compulsory licensing in simple language
