Catalina Marketing sued Advanced Promotion Technologies; the case settled in November 1994 with a cross-license and cross-distribution agreement. The sources described three Catalina patents but did not name patent numbers; the narrative states US 4,910,672 is a likely but unconfirmed member of the asserted set.
Catalina Marketing sued Fuel Marketing Solutions; the case settled with a license and FMS acknowledged validity of Catalina's patents. The three asserted patents were described by subject matter but not named; the narrative states US 4,910,672 is the strongest circumstantial link but unverified.
Inter-Act Systems sued Catalina Marketing in 1996, asserting Inter-Act's own patents (not Catalina's US 4,910,672); a later-filed companion asserted eight additional Deaton patents. Catalina provoked four USPTO interference proceedings challenging the Deaton patents; status was pending as of the source.
Southwest Efuel Network sued Catalina Marketing in N.D. Tex.; all claims were dismissed without prejudice on Nov. 20, 2012. The suit was on Efuel's own patents, and the narrative states US 4,910,672 (expired 2007) could not have been asserted.
