Various courts have held that by putting something in the trash, you are relinquishing your ownership of those goods. However, apparently that might not apply to music. William Patry has the story on an unfortunate decision by our court system, suggesting that if you find a CD in the trash and sell it you may be charged with copyright infringement. The story of the case is as follows: BMG famously offers a CD and DVD "club" that sends out new CDs and DVDs on a regular basis to subscribers. Sometimes those subscribers move and cannot be found or for whatever reason the discs are determined to be "undeliverable." BMG so devalues its own discs that it has told the post office to throw out the undeliverable discs, rather than spend the postage to have them sent back to BMG. The post office dumps the discs in its dumpsters -- at which point a Postal Service employee dumpster dives to rescue them. He then goes and sells those discs to local stores, cashing in to the tune of nearly $80,000.
