Actually, the IBM public license has a very similar clause

   If Recipient institutes patent litigation against a Contributor
   with respect to a patent applicable to software (including a
   cross-claim or counterclaim in a lawsuit), then the patent licenses
   granted by that Contributor to such Recipient under this Agreement
   shall terminate as of the date such litigation is filed.  In
   addition, If Recipient institutes patent litigation against any
   entity (including a cross-claim or counterclaim in a lawsuit)
   alleging that the Program itself (excluding combinations of the
   Program with other software or hardware) infringes such Recipient's
   patent(s), then such Recipient's rights granted under Section 2(b)
   shall terminate as of the date such litigation is filed.

and that is allowed in main.  In fact, at the time when it was
accepted someone (I don't remember who) thought quite highly of this
particular section.
