Abstract:
Objective:To apply patent metrics to analyze the distribution, development trends, and characteristics of patents related to orthokeratology lenses for assisted wearing, providing a reference for the research and development of such patents.Methods:Patents related to orthokeratology lenses for assisted wearing were retrieved by computer from the China National Intellectual Property Administration database, incopat, Derwent Innovations Index, Free Patents Online, Organisation Africaine de la Propriété Intellectuelle, and IP Australia. The search timeframe was from the establishing of these databases until March 8, 2024. Patent metrics methods, word frequency analysis, and high-frequency word co-occurrence analysis were used for data analysis.Results:A total of 60 relevant patents were selected. The development of orthokeratology lens-assisted wearing patents began relatively late but has shown a strong growth trend, reaching a peak around 2015. Chinese patents accounted for the largest share (91.7%, 55/60) , with Zhejiang Province, Beijing City, Jiangsu Province, Guangdong Province, and Shanghai City having the highest number of patents. The majority of the applicants were enterprises. The research focus in this field is on mechanical assistance patents for lens wearing, with cutting-edge technologies focusing on monitoring the displacement of lenses relative to the pupil and providing timely feedback and guidance.Conclusions:This study, using patent metrics, word frequency analysis, and high-frequency word co-occurrence analysis, provides a reference for patent applications and product development in orthokeratology lens-assisted wearing in nursing.
