yeah - I can agree with you on that point - it's starting to get very silly now.
I was going through some of my g/f's documents seeing what lawsuits they have outstanding - it's surprising how many companies are issuing patent suits over what could be considered prior art.
It holds very disturbing implications for the future, and it's an issue that can only be resolved by professional (as opposed to legal) review of all outstanding patent cases.
If this happens, then hopefully there would be more of an impetus to (i suppose) start acting more sensibly over copyright, patent and source-code issues.
