Just FYI I examined few other IPR disclosures and apparently there are 
many more offering royality-free licences yet containing protection 
against patent litigations. They apparently can go together just fine.

Example:

Subject to the terms and conditions of this License, Google hereby 
grants to You a perpetual, worldwide, non-exclusive, no-charge, 
royalty-free, irrevocable (except as stated in this License) patent 
license for patents necessarily infringed by implementation (in whole or 
in part) of this specification. If You institute patent litigation 
against any entity (including a cross-claim or counterclaim in a 
lawsuit) alleging that the implementation of the specification 
constitutes direct or contributory patent infringement, then any patent 
licenses for the specification granted to You under this License shall 
terminate as of the date such litigation is filed.

Btw:

Results 1-10 of about 2,150 for "royalty-free" AND IPR. (0.14 seconds)
Results 1-10 of about 198 for "royalty-bearing" AND IPR. (0.24 seconds)

The query results are self explanatory :).
