Omar Swartz presents a number of good arguments in favour of treating the formulae for making human immunodeficiency virus (HIV) and other life-saving drugs as public goods rather than private property: ideas can be shared without being used up; the most effective use of blueprints for life-saving medicine is to provide drugs to sick people; finally, it is clearly unreasonable if 'a person who owns something...can dispose of (or control access to) that [thing]...without regard for others.'
