I. Concept
Invention patent: refers to a new technical scheme proposed for a product, method or its improvement. An invention that can be patented can be a product invention or a method invention.
Two. Materials to be prepared when applying for a patent for invention
1, name of invention:
The name should simply and clearly reflect the theme and type of the invention (no more than 25 words). Names shall not use names, place names, trademarks, models and commercial propaganda terms, nor code names or ambiguous words. As far as possible, technical terms in the international patent classification table, terms specified in national standards or commonly used normative terms should be adopted.
2. Prior art (background of invention):
The state of the prior art which is closest to the technology of the present invention should be stated, its advantages should be explained, and its main problems and shortcomings should be pointed out realistically, such as the patent XXX of a country or the name of a publication. In the case that the invention is a product, if it is difficult to clearly describe the structure of the prior art in words, it can be illustrated with attached drawings.
3. Technical scheme of invention and creation:
For the invention and creation of products, the names of components, the connection relationship between components, the principle of action and the working procedures shall be clearly and completely explained with the attached drawings, which shall be subject to the realization of ordinary technicians in the technical field. For electronic inventions, circuit diagrams or block diagrams should be provided, and their structural characteristics should be explained in combination with hardware. For methodological inventions, such as chemical engineering, medicine, food, etc., the limitations of process steps and conditions should be explained as far as possible, and the process flow chart should be provided. Drugs need to provide clinical proof.
4. Effects and advantages of the invention:
It should be explained that the invention has positive effects and advantages compared with the prior art, and these advantages and effects must be directly obtained by adopting the technical scheme created by the invention. This part of the description can be explained by the functional relationship of the structure, or by theoretical analysis or experimental data.
5. Attached drawings:
The attached drawings shall be drawn according to mechanical drawing standards. Generally, Chinese characters are not allowed to be written on the drawings of the drawings, and the parts and components shall be marked with Arabic numerals, and the names of the parts and components represented by each mark shall be stated in the instructions. The label of the same part shall be consistent in all drawings, and different parts shall not be represented by the same label. When drawing is difficult, you can entrust an agency to draw.
6. Example:
For the invention of product category, the embodiment is the specific design to realize the invention and creation. This part should be accompanied by attached drawings, and the numbers in the drawings should be marked after the corresponding parts. The embodiment should include all the contents of the technical scheme in the third part above, and make a detailed explanation. Each drawing should indicate that each marked part is mentioned at least once in the embodiment. If necessary, it can explain its function, dynamic structure and usage. If there are multiple embodiments, each embodiment should be described in detail.
For the invention of the method, the process flow, operation steps and specific process parameters should be explained in detail, and the implementation scheme combining various process parameters should be provided.
For the invention of material formula, several examples of different components and proportions should be cited, and their manufacturing methods should be briefly described.
