1. About Patent Law in Mianyang, China

Mianyang is a key technology hub in Sichuan Province, with many high-tech firms and research institutions. Patent law in Mianyang operates under national Chinese statutes and local practice to protect inventions, designs, and utility models.

Invention patents require a higher standard of novelty and inventiveness, while utility models focus on technical solutions with practical applicability.

Patent Law of the PRC

The Patent Law of the People’s Republic of China governs the creation, protection, and exploitation of patents nationwide, including Mianyang.

Interpretations and Enforcement Guidance on Patent Infringement

The Supreme People’s Court has issued several interpretations to harmonize practice across provinces.

For practical guidance, counsel in Mianyang consult these interpretations when pursuing or defending patent litigation and when seeking fast-track enforcement channels under local procedures.
