Summary
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.
