Masnick brings up the concept of an "independent invention" defense to patent infringement, showing Masnick doesn't have a clue how patent law works. The deal in patent law is a simple quid pro quo: the inventor tells the public what his invention is and how it works and, in return, gets a right to exclude (not a monopoly right) for a limited time. The invention is supposed to be novel, nonobvious, and useful. By making the invention public, the inventor is advancing knowledge and people ARE SUPPOSED to read the patent.
Masnick writes: It's almost always independent invention . Gee, Mike, re-inventing the wheel is what we are trying to avoid here. And you want to give somebody a "free pass" for re-inventing what is already known?
The patent law is strict liability. If someone does something or makes something that falls within the scope of a claim, it's infringement whether there is knowledge of the claim or not. That's an incentive to read the known literature, not to re-invent it.
Sometimes people take things. Contemplate the Sticklen matter.
