SLP2000: But one thing - as you can abandon your property (by throwing it away or in case of real estates by not using it while someone else is, for a certain amount of time, who claims it's his real estate - at least in Poland that's how it works), there is no reason not to let copyright owners to abandon their IP property.
Nope. You can abandon only movable objects, not rights.
IP is not an object nor item, it's right.
You cannot abandon your right to work, to privacy just because you don't use that right. You have to make a direct statement "I will not use my IP rights for this item anymore, you are free to copy it" to do "abandon"
Presumption that somebody has abandoned his IP , because he's not selling it anymore is unacceptable.
Can I distribute your old emails from your email box , because you don't use it anymore?
SLP2000: I think that there should be new copyright law that will protect a copyright holder for 70, 75 or even 100 years as long, as he provides book/movie/game/song for sale to everyone.
But, there should be law that obligates the copyright holder to provide book/movie/game/song for sale to everyone after 15/20 years from the release date. If the copyright holder fails to do that, everyone should be able to legally download it from the Net ot make a copy.
And your emails. And your poem written to that hot chick from senior class.
