I think 5 years is a good time limit for everything ( for non commerical use )
And 20 years for commerical use of everything.

Where commerical use means some one somewhere is making money off it.

And if a project was funded by governement at all grants then it is automaticly placed in the public domain.

The public domain is a good thing and all of society benifits from it.

Companies still make money off public domain. Ever buy a book that was written before 1923 ... Its all public domain.

There is a lot of music available in the public domain as well.

Now for the concept of trademarking and patienting ideas and concepts.... I think that this should not be allowed.... Society does not benifit one bit from that.

Imagine if someone patiented the idea of a vechile that moves on tracks in the 1820's.... With todays laws...

Innovation and copyrights and patients travel down two seperate roads in opposite directions...
