First of all, according to the provisions of the patent law, inventions, utility models and designs have different protection objects, specifically:
Invention as mentioned in the patent law refers to a new technical scheme proposed for a product, method or its improvement.
The term "utility model" as mentioned in the patent law refers to a new technical scheme suitable for practical use for the shape, structure or combination of products.
The term "design" as mentioned in the Patent Law refers to a new design that is aesthetically pleasing and suitable for industrial application, which is made by the shape, pattern or combination of products and the combination of colors, shapes and patterns.
Secondly, the examination procedures of the three patents are different: the invention is a two-trial system, that is, it needs to go through the first trial and the actual trial before being granted a patent right. New designs and designs can be authorized after preliminary examination.
Finally, the three protection periods are different, the invention is 20 years, and the new type and design are 10 years.
If you look at your question carefully, do you want to ask what is the difference between the "claims" of the three patents?
"Patent claim" is an indispensable document in the application documents of inventions and new patents, and it is a legal document to determine the scope of patent protection. Therefore, the requirements for writing this document are specified in the Patent Law, its implementing rules and the patent examination guide.
There is no "claim" for design, and the protection scope of design shall be subject to the pictures of design.
I wonder if the above answers have the answers you need, hehe.
