And should the purchasing party know that the patent will expire on the moment of purchase, the patent will hold no value and will never be purchased.
There is a middle ground, where a patent once transferred by the original patent holder cannot be extended, or is perhaps reduced, or the patent cannot be resold. Something of the sort. This would maintain the patent's value for the inventor in a market, as well as provide reasonable measure against patents being scooped up and plaguing IT for decades.
Better yet, though, no more software / algorithm patents.
