TL;DR: The patent covered any salt solution “between 1 per cent and 25 per cent of the total volume of treatment”. The court ruled that 0.77 falls within that range, because '1' can mean anything between 0.5 and 1.5, because 'figures, no less than words, may take their meaning from the context in which they are used'. Remarkable.
