摘要
超声波技术广泛应用于医学、军事、工业、农业等各个领域,其专利数量庞大,且IPC分类分布范围极广,关键词表述也不够精确,申请人采用关键词、IPC等通常的检索策略对超声波现有技术的检索经常无法达到预期效果。通过对FI/F-Term,Patentics等特色检索手段的研究,实现对超声波专利技术的有效检索,希望对本领域申请人在申请专利之前的现有技术检索工作有所帮助。
Ultrasonic technology is widely used in medical, military, industrial, agricultural and other fields, the number of its patents is very huge, and the IPC classification has a wide distribution, keywords can＇ t accurately express, applicants usually can＇ t achieve the desired results when using keywords and IPC searching ultrasonic technology patent. FI / F-Term and Patentics are used to search ultrasonic technology patent effectively, hoping to help the applicants find the closest existing technology before applying a patent in this area.
