Will Microsoft Vouchers Provide Free License to Thier Patents?

According to Todd Bishop of Seattle PI, who broke the story, SUSE vouchers have no expiration date. Groklaw claims that this legal oversight looks to be the wooden stake in the Novell-Micorosoft patent peace agreement. Groklaw quotes Eben Moglen:

Novell's activity will be protected by the fact that it was complete as of the date in November, which is the effective date of their deal with Microsoft. [The GPL revisions won't be retroactive.] Microsoft's activity will begin to disperse patent defenses into the community. When GPL 3 goes into effect, every Microsoft coupon handed to somebody, which results in the shipment of a Novell Server Edition product to that coupon-holder, will result in a conveyance of broad patent defenses to parties throughout the community....

The coupons have no expiration date, and Microsoft can be sure that some coupons will be turned into Novell in return for software after the effective date of GPL 3. Once that has happened, patent defenses will, under the license, have moved out into the broad community and be available to anybody who Microsoft should ever sue for infringement.
