1. Invention patent.
Invention patent refers to a creative technical scheme in terms of products or methods. Invention patent is the highest level to protect technological innovation, which is very important for inventors of new products or technologies.
2. Patent for utility model.
A patent for utility model refers to a technical scheme with a new structure or an improved shape as far as a product is concerned. Compared with invention patents, utility model patents have lower requirements for creativity, but they still need to meet the requirements of novelty and practicality.
Third, the design patent.
Design patent refers to the product design scheme with appearance as the main feature. The design patent is mainly to protect the appearance of products, including the shape, pattern and color of products.
The scope of protection of these three patents is different. The invention patent has the widest scope of protection, followed by the utility model patent and the design patent is the narrowest. At the same time, the application and approval processes of these three patents are also different. The application for invention patents needs to undergo more rigorous examination, while the patent for utility model and the patent for design are relatively simple.
Patent introduction:
Patent literally refers to exclusive rights and interests. The word "patent" comes from Latin "Litterae patentes", which means open letters or open documents. It is a certificate used by medieval monarchs to issue certain privileges, and later refers to the exclusive right certificate signed by the British king himself.
In modern times, patents are generally documents issued by government agencies or regional organizations representing several countries according to their applications. This kind of document records the contents of the invention and creation, and in a certain period of time, it has produced such a legal state that the patented invention and creation can only be implemented by others with the permission of the patentee.
As the most effective technical information carrier, Li Wenxian has collected more than 90% of the latest technical information in the world, five to six years earlier than the information provided by general technical publications, and 70% to 80% of inventions are only disclosed through patent documents, but not in other scientific and technological documents. Compared with other document forms, patents are more novel and practical.
