The landscape may have changed, but the law has not. I was speaking to the law.
This cuts to the core of my original ('poor attitude') comment. International royalty / licensing fees increased from US$2.8 billion in 1970 to US$27 billion in 1990, and to approximately US$180 billion in 2009 – outpacing growth in global GDP. When you have a nut that skips an order of magnitude every decade, based upon intellectual property alone, we're left with crazy disparate ownership of IP on the side of businesses.
IIRC, around 1980, only about 60% of US companies were IP based. Now its over 95%. Basically, the entire US economy now runs on IP. Its not individuals who are benefiting from this increase in business owned IP. Enforcing your patent, on a big business, is like bringing a knife to a gunfight. They would likely settle out of court, or bury you depending on how much your asking for, perhaps both. Yes, the law is on your side if you are victim of legitimate patent infringement, and in the 1980s, you might have had a shot at enforcing your patent, up to and including jury trial. But now, the court system itself is where enforcement of ownership now comes to die, instead of an reasonably affordable and speedy trial.
Its turned into a poker game, where big business holds all the chips, and individuals barely have enough for the blinds to even play.
