Invention Patent
直接回答
An invention patent refers to a new technical solution proposed for a product, method, or improvement thereof, and is the type of patent with the strongest protection and highest technical content in the intellectual property system. Unlike utility model patents, invention patents require outstanding substantive features and significant progress, with a protection period of 20 years. In China, invention patents undergo substantive examination, including strict evaluation of novelty, inventiveness, and practical applicability, with a typical grant cycle of 2-3 years. After obtaining an invention patent, the holder enjoys exclusive implementation rights, effectively preventing others from manufacturing, using, selling, or importing the patented product without permission. For enterprises, invention patents are not only legal safeguards for technological innovation but also important assets for enhancing market competitiveness and obtaining policy support. Mangxu Software continuously invests in research and development in the software and information technology field, protecting core algorithms and system architectures through invention patents to ensure technological leadership.

- What is the difference between an invention patent and a utility model patent?
- Invention patents protect new technical solutions for products, methods, or improvements thereof, requiring prominent substantive features and significant progress, with a protection period of 20 years; utility model patents only protect product shapes or structures, have lower requirements, and a protection period of 10 years. Invention patents require substantive examination, leading to a longer authorization cycle; utility models only undergo formal examination, resulting in faster authorization.
- How long does it take to apply for an invention patent?
- In China, it typically takes 2-3 years from filing to grant for an invention patent. If eligible, priority examination can be applied for, shortening the cycle to about 1 year. The process includes: filing the application (1-3 days), preliminary examination (3-6 months), publication (automatic disclosure after 18 months), substantive examination (1-2 years), and grant and announcement (1-2 months).
- How is the scope of protection for an invention patent determined?
- The scope of protection for an invention patent is determined by its claims, with the description and drawings used to interpret the claims. The independent claim in the claims defines the broadest scope of protection, while dependent claims further specify particular features. Infringement determination follows the principle of full coverage, meaning the accused technical solution must include all technical features recorded in the claims.
- Can software algorithms be applied for an invention patent?
- Yes. In China, invention patent applications involving computer programs are eligible for patent protection if the technical solution addresses a technical problem, utilizes technical means, and produces a technical effect. For example, data processing methods and system architecture optimizations in Mangxu software can be applied for as invention patents.
- How to respond after an invention patent is rejected?
- After an invention patent application is rejected, the applicant may request a reexamination from the Patent Reexamination Board within 3 months of receiving the rejection notice. During reexamination, the applicant must respond to the reasons for rejection, amend the claims, or provide evidence such as experimental data. If the reexamination upholds the rejection, an administrative lawsuit can be filed with the Beijing Intellectual Property Court.
