Automatic extraction of fabrication conditions for NdFeB magnets from US patents was examined. Since the tables of US patents frequently include the fabrication conditions for sintering and thermal annealing, the extraction was mainly examined. String matching with index terms was used for the extraction. The extracted data for sintering temperature showed that the temperature was optimized at 1000–1080 ºC around 2020 year. The automatic extraction will be performed also from main text of US patents, and the results will be reported in the meeting.
