[Purpose/significance]Studying the patent citation mechanism under the patent application and patent censorship and clarifying the effectiveness of patent citation evaluation are both important prerequisites to ensure an objective and reasonable academic evaluation.[Method/process] This paper took samples of litigation patents and licensed patents from the United States, China and Japan. It analyzed the relevance between patent citation frequency and patent value. It also made an in-depth analysis on the effectiveness of patent citations on the citing patent and cited patent, combining with the patent application and patent censorship.[Result/conclusion] Patent citation is a mixed index of positiveness, negativeness and neutrality for patent value. The evaluation of patent value should be based on a detailed analysis of motivation for citation and playing the roles in actual fields. Otherwise, patent citation does not have evaluation effectiveness for patent value.
