Multi-patent pools based on different technical standards are appearing in many technique industrieswith competitions becoming intensive among technical standards. Theoretical model of cumulativeinnovation effect of competitive patent pools based on different technical standards isdeveloped by dynamic game theory in this paper to study the cumulative innovation effect ofcompetitive patent pool under the different patent types of relationship between patents, whichare blocking patent, substitutability patent and additional innovation patent. This research indicates:the R&D investments of an enterprise inside a patent pool increase or decrease as the R&Dinvestments of other enterprises inside the same patent pool decrease or increase or as the R&Dinvestments of the enterprises inside another patent pool or the R&D investments of the enterprisesoutside patent pools increase or decrease during the patent race of blocking patent. Thebigger differentiation degree between patents is, the R&D investments of all enterprises are moreduring the patent race of substitutability patent. The R&D investments of an enterprise inside apatent pool are bigger than outside the patent pools during the patent race of additional innovationpatent.
