It's good t know that some people will continue to make my hate list...
"Patents as knowledge-sharing tools may seem counterintuitive at first. After all, patents do give their owners the right to exclude others from using a technology. But even in this case, denying use is very different from denying to others knowledge of the new technology, which patents by law are required to disclose."
And then again, if you find out how a wheel looks and find a way to actually build one from an obfuscated patent filing entilted "Supportive rotary devices which are ALL MINE!" -- but you are ultimately forbidden to do so, what's the use?
As I recall, it is recommended practice at MS to avoid reading patents or looking for patents covering the same areas as one is working on because a) they are impossible to understand b) if the judge finds out that you checked them out before going to work on your new project you are just making your case worse.
Precise gutshots for anyone extolling "Intellectual Property", please.
