A district court in Munich (Landgericht München I) ruled in July 2007 that Skype had violated the GNU General Public Licence 2.0 because it had sold a SMC Networks Linux-based VoIP telephone (WSKP100) without providing both the copy of the license and the source code of the software. In particular, together with the product, there was only a leaflet pointing to an URL where the text of the license and "information on obtaining access to the GPL Code" could have been obtained, whereas according to art. 1 GPL v. 2.0, the licensee is required to "give any other recipients of the Program a copy of this License along with the Program". Moreover, art.3, par.1 together with par.3, requires the licensee to accompany the program/product either with the "complete corresponding machine-readable source code" or to offer access to copy the source code from a designated place, provided in the latter case that distribution of executable or object code is made by offering access to copy from the same place. Therefore, only if the binary had been made available in Internet for download, which was not the case, the offer to download the source code would have been in compliance with the GPL terms.
One of the appeal judges is cited to have said, as reported by Harald Welte's blog "if a publisher wants to publish a book of an author that wants his book only to be published in a green envelope, then that might seem odd to you, but still you will have to do it as long as you want to publish the book and have no other agreement in place". Skype's legal counsel thought it wise to withdraw the appeal.
