"Microsoft Files Motion in Apple v. Samsung to Hide Patent License Agreement Terms ~pj"
As explained in the accompanying declaration of Tanya Moore, Microsoft's General Manager of Outbound Licensing, Exhibits 3A and 3B to the Teece Report contain sensitive confidential and proprietary business information from the Confidential Agreement between Microsoft and Samsung. The Teece Report summarizes sensitive portions of the Confidential Agreement, including the licensed technology, term of the license, royalty rates, and payment information, among other things. (Moore Decl. at ¶¶ 3-4).
Samsung sells a lot of their hardware with MS software on it and are dependent on favorable licensing terms. This business Samsung does with them overshadows all their other partners in terms of revenue.
And that's relevant to Microsoft ARM tablets how? x86 devices don't have locked bootloaders, and Windows ARM tablets don't exist, so the reason you were downvoted isn't Microsoft fanboys, it's that you're wrong and seemingly quite proud to be so.
