Plaintiff Geomatrix sells a septic system that substantially differs from those sold by its competitors. It asserts defendants, those competitors and NSF International (the primary standard-setting organization for the wastewater product industry), conspired to exclude its unique system from the marketplace. The district court dismissed Geomatrix’s claims on several grounds, including the Noerr-Pennington doctrine and for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6). We agree that dismissal is proper and affirm.
