Abstract Considering the existence of patent intermediaries in the patent market, this study builds a game model that combines industrial competition, technology licensing and patent auction. The equilibrium of different stages is obtained to analyze the impact of the network externality intensity and degree of innovation on technology licensing strategy of firms and the influence of the existence of patent intermediaries on industrial competition, innovator profits and consumer welfare. If it is non-innovative, the patent intermediary will always win the patent; if it is non-innovative, the bidding result is related to the network externality intensity and efficiency difference of bidding. If the patent intermediary wins the patent in the auction, the patent will always be granted to the two companies. If a company wins a patent, its patent licensing decision is related to the degree of technological innovation and the network externality intensity. The existence of patent intermediaries does affect the market equilibrium of industrial competition and increases the profits for innovators and consumer welfare.
