Currently, China is advancing from a “patent powerhouse” to a “patent superpower,” shifting its patent strategy from quantity-driven growth to quality enhancement. This paper explores the importance and strategies for improving patent quality and reasonably defining claim scope within the context of building an intellectual property superpower. Research indicates that overly broad claim scope leads to difficulties in obtaining patents and unstable rights, while overly narrow scope weakens patent protection. To enhance patent quality, coordinated efforts are required at both the application and examination stages: During application, strengthen publicity and guidance, standardize application procedures, and leverage patent pre-examination services. During examination, rigorously control grant quality, enhance examination capabilities, and improve the reasoning behind rejections. Systematic quality improvement will foster high value patents and support the implementation of innovation-driven development strategies.
