Patent application materials are mainly written from the following six aspects:
1, name of invention:
The subject of the invention patent should be clearly and accurately marked. The name shall not contain non-technical words, trademarks, models, names, place names or commodity names. , and should not exceed 25 words.
2. Background:
Related to the invention theme and the closest existing technology (all the known technologies before your application date), make an objective evaluation and point out the existing problems and difficulties.
3. Purpose of the present invention:
In view of the problems and difficulties existing in the existing technology, briefly put forward the problems to be solved and the goals to be achieved in your invention.
4, technical scheme (core):
Clearly and completely describe the technical scheme adopted to achieve the above purpose, and especially point out the invention points different from the prior art, so as to determine the scope protected by the claims. Specifically, for the invented product, it is necessary to statically describe which parts it consists of, and at the same time, in order to clearly describe the shape, structure and connection mode of the product. It should be explained with the attached drawings, and the working process or principle of these structures should be dynamically described; Method of invention: The process steps and the numerical range of process parameters of each step, such as time, temperature, pressure, formula and dosage, should be described, and specific examples should be given. The number of examples depends on the content of the present invention. If there are many alternatives and choices, several implementations can be reversed. The explanation should include the principle and function of summation. The above clarity and completeness are limited to those skilled in the art who can practice the invention.
