Patent dataset in the field of nuclear fusion technology from 1955 to 2024

Based on the overall distribution of applications throughout the entire time period of the patent database and the time lag of patents, the retrieval time is limited to 1955-2024, and the collection time is April 2, 2025. At the same time, to avoid the complexity of citing different types of patents, the patent types were limited to application and authorization, and a search yielded 30129 patents.

After simple same family merging, removing duplicate irrelevant data and missing attribute data, 12781 valid patents were finally obtained. Among them, the row labels in the table represent the attribute information of relevant patents, such as title, abstract, application number, applicant, etc. There are some missing data such as cited patents and citation times, because the patent has not been cited, transferred, etc. Specific search formula: (TIAB=("nuclear fusion" OR "magnetic confinement fusion" OR "inertial confinement fusion" OR "magnetic inertial fusion" OR "fusion plasma" OR "tokamak" OR "Stellator" OR "magnetic mirrors" OR "θ - punch" OR "fusion reaction" OR "thermonuclear fusion" OR "cold fusion" OR nuclear fusion OR magnetic confinement fusion OR fusion plasma OR inertial confinement fusion OR magnetic inertial fusion OR tokamak OR simulator OR magnetic mirror OR pinch) NOT ("nuclear fission" OR "uranium") OR IPC=(G21B) OR CPC=(Y02E30/10)
