Commentary, and a link to the guidelines in the original German, are available on JUVE Patent. An unofficial translation into English is available from Florian Mueller on FOSS Patents. The guidelines relate to the antitrust-based compulsory license defense, which under German and E.U. law means that the patent owner can't get an injunction if, under the circumstances, it is abusing its dominant position. I may have more to say about the guidelines at some point.
