1. If pursuant to or in connection with a single transaction or arrangement you convey or propagate by procuring conveyance of a covered work and grant a patent license to some of the parties receiving the covered work authorizing them to use propagate modify or convey a specific copy of the covered work then the patent license you grant is automatically extended to all recipients of the covered work and works based on it A patent license is discriminatory if it does not include within the scope of its coverage prohibits the exercise of or is conditioned on the non exercise of one or more of the rights that are specifically granted under this License You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software under which you make payment to the third party based on the extent of your activity of conveying the work and under which the third party grants to any of the parties who would receive the covered work from you a discriminatory patent license a in connection with copies of the covered work conveyed by you or copies made from those copies or b primarily for and in connection with specific products or compilations that contain the covered work unless you entered into that arrangement or that patent license was granted prior to 28 March 2007 Nothing in this License shall be construed as excluding or limiting any implied license or other defe
