In my personal opinion? If you are they person/company able to provide a necessary good (a patented, life-saving medicine say), then you have a moral obligation to sell it.

Similarly, I believe it immoral to sell a necessary good at exorbitant prices, but fine to sell luxury goods at whatever price you like. Of course, the question follows: What counts as "necessary"? I don't have an easy answer for that one :)
