You previously just phrased my 3rd option differently to artifically create a 4th option.
Now you don't take into account that I explained 3 different approaches: grant a free license, grant a FRAND license, and prohibit any implementation of the patented invention only to foreclose competition, which is exactly what IBM (a monopolist in the context we're discussing) tried. Fortunately, the European Commission is investigating IBM for suspected violations of EU competition law.
