Abstract Based on the PageRank and ArticleRank, the paper uses the times cited criterion and citation network to calculate the rank scores,thus establishes the PatentRank Algorithm. Then it analyzes the relevant digital library patents of the USPTO patent database and the results show that the PatentRank Algorithm can differentiate patents which of the same number of citations. The originality is a novel application of the PageRank Algorithm.
