I don't know anything for certain except UK rules on this one, but if the poser products count as software (as in code) then the copyright rules depend on the license for each product. To give an example, compare a full boxed product of Microsoft's XP operating system with an OEM version of the same operating system. It is legal to install the full boxed product on one machine, then to completely remove it from that machine and give or sell the product to someone else as long as any legal backup copy and all the associated documents are passed along with it and the original licensee retains nothing. It is NOT legal to do the same with an OEM version- the OEM verion is only licensed for use on the machine it was sold with. it is Microsoft who sets the terms of the two different licenses. I beleive this is the same in the U.S. If the poser products in question follow the same laws then it is down to the merchants in question to state what their license allows when they sell the product. This all assumes, of course, that they count as software not some other form of artistic expression. Any real copyright experts out there??
