Yes, quite so. Maybe you should use the language given in the
Academic Free License or the IBM Public License:
This License shall terminate automatically and You may no longer exercise
any of the rights granted to You by this License as of the date You commence
an action, including a cross-claim or counterclaim, against Licensor or any
licensee alleging that the Original Work infringes a patent. This
termination provision shall not apply for an action alleging patent
infringement by combinations of the Original Work with other software or
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 any patent licenses granted by that Contributor to such
Recipient under this Agreement shall terminate as of the date such
litigation is filed.

"Intellectual property claims" and "software patents" are terms
that are very hard to define. Besides you define the scope of the clause
in such a vague way that I have no idea what I'm no longer allowed to do.
The above clauses clearly spell out what is and is not permitted.
