Biotech Values

As an example of the problem try finding any patent that held off competition through physical broadness of the patent for the entire duration of the patent.

An easy example to find is a very famous case, Polaroid instant film. Yes, Kodak did market, but they had to pull and pay damages. It was something like 30 years after Land that the first non-infringing competitor came to market.

In todays high tech world you often have so many interlocking patents that there really is no such clear concept. The royalties will either be small enough such that the cost to R&D around is not justified, or traded off against other's patents.
