This study is structured in two phases, aiming to develop an intelligent approach to analyzing the trend and evolution of patent litigations. The first phase involves macro- and micro-patent analyses of the related technology domain. Macro patent analysis elucidates the fundamental patent information in the drone industry, while micro patent analysis leverages the technology function matrix (TFM) to identify R&D hotspots and potentials. The second phase involves litigation (judgement) mining based on large language model (LLM). Beginning with the construction of a knowledge ontology, the domain infringement landscape can be detected through TFMs. A comparative analysis of the two-phase TFMs (i.e., both TFMs of patent and infringement allocations) is then conducted to pinpoint the key legal actions and the relevant technology. To drill deeper in infringement mining, dynamic topic modeling (DTM) is applied to analyze trends and dynamics in drone controller technology over time. This study aims to strengthen IP protection by developing an intelligent litigation mining approach that adopts large language model (LLM) and uses UAV/drone litigation studies as examples to show how the approach being applied in the industry.</div></div>","PeriodicalId":51794,"journal":{"name":"World Patent Information","volume":"80 ","pages":"Article 102332"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study developed a new dataset containing the Orange Book listed patents based on USFDA calendar year 2020 approvals. It aimed to analyze the patent prosecution process, specifically examining the severity of office action rejections through the patent rejection severity scale and their impact on prosecution timelines. Out of 437 patents, the claim scope significantly changed for 322 (65 primary and 257 secondary) during prosecution. The results indicated that the obviousness rejections occurred more frequently for secondary patents, with a rate of 72.76 % (187/257), compared to primary patents with 33.85 % (22/65). Further analysis revealed a strong association between the severity of office action rejections and the number of office actions (p-value of 0.0036) and prosecution time (p-value of 0.0008) for secondary patents. The study also emphasized the necessity of implementing various strategies and the use of experimental data to mitigate patentability rejections and circumvent prosecution delays.
