[目的/意义] 技术研发的核心是人才。研发团队是各领域技术发展的重点关注对象，也是机构研发实力的重要体现。[方法/过程] 以德温特创新索引（DII）专利文献为分析对象，明确发明人人名消歧规则，利用发明人共现聚类确定主要研发团队，然后以3D打印的数字光处理相关专利来进行人名消歧后研发团队识别的实证分析。[结果/结论] 证明专利发明人人名消歧有利于发明人专利数量的准确分析。

[Purpose/significance] Talent is the main factor in technology research. R&D teamsare the focus of technology development in various fieldsandimportant manifestation of the competence of an institution. [Method/process]Based on Derwent Innovation Index (DII) patent documents, the rules for the disambiguation of patent inventors’ names weredefined, and the key R&D teams were identified by inventors clustering. Then, an empirical study was carried out on patents related to Digital Light Process (DLP) of 3D printing. [Result/conclusion]It is shown that the disambiguation of patent inventors’ names is helpful to accurately analyze the number of inventors’ patents.
