O.K. Okiemockbird, I am weighing all of your arguments and will consider all at an hour when my brain is functioning at a higher speed.
While I favor the Bono Copyright Extension, I think that centuries and millenia are SLIGHT exaggerations. I think that the life of the last surviving author/composer plus X years is very fair.
While drug companies do very well financially, it never seemed fair to me to start the countdown on a drug patent from the date the patent was granted. Since considerable time may lapse till a drug is approved by the FDA, it wpould seem to be logical to start the countdown from the date of approval. [I have no financial interest in any drug company, except I do ingest a lot of expensive medications]
