How to write a patent application?

How to write a patent technical disclosure is a reference document for the inventor or applicant to submit his invention and creation to the patent agency in written form. Mainly to improve the writing quality and efficiency of patent application documents, so that patent agents can understand the characteristics of the inventor's invention ideas more easily. The technical disclosure required by the applicant mainly involves the same contents in the description of the invention or utility model, which are all necessary contents of the patent application documents, and the applicant can omit them if he has difficulties in writing. The main contents are as follows: 1. The name of the invention or utility model should be concise, and the technical terms commonly used in this technical field can clearly reflect and embody the theme and type of the invention. Don't use non-technical terms, names, trademarks, models or product names of inventions, or commercial propaganda terms. The name should preferably correspond to the categories and groups in the international classification table, generally no more than 25 Chinese characters. 2. The technical field to which the invention belongs refers to the technical field to which the invention directly belongs or directly applies. It is neither a broad technical field to which it belongs or applies, nor an adjacent technical field, nor an invention or utility model itself. 3. Background art is also called prior art.. This part should focus on the description and evaluation of the existing technology before the application date, that is, recording the background technology known by the applicant, which is useful for understanding, searching and reviewing the application. Generally, at least one prior art document closest to this application should be cited, and if necessary, several relatively close comparative documents can be cited, which can be patent documents or non-patent documents. A brief introduction to the existing technology should include three aspects: (1) indicate its source, usually by giving comparative documents or pointing out the well-known disclosure; (2) Briefly explain the main related contents of the existing technology, such as the main structure and principle, or the technical means and methods adopted; (3) Objectively point out the problems and deficiencies of the existing technology, explain the reasons for these problems and deficiencies when possible, and avoid using defamatory language. 4. The purpose of the invention refers to the technical scheme for applying for a patent for invention or utility model to solve the problems existing in the prior art.. Usually, the task to be solved is put forward according to the problems existing in the recent prior art and the effects obtained by the invention or utility model. The specific requirements are as follows: (1) It should be adapted to the theme and invention type of the invention or utility model; (2) Positive statements should be used to directly, clearly and objectively state the purpose and clearly explain the problems to be solved; (3) The technical problems to be solved should be specifically reflected, and general expressions such as "energy saving" and "quality improvement" should be avoided, but the specific contents of the technical scheme should not be included. (4) Do not use advertising language. 5. This part of the technical scheme is the core part of the specification, and the description of this part should enable the technical personnel in the technical field to understand and achieve the purpose of the invention or utility model. The technical scheme adopted by an invention or utility model often consists of a collection of several technical features. The technical scheme shall be clearly stated and complete, including all the necessary technical features to realize the purpose of the invention; If it is a product invention, it should explain the composition of the product and the relationship between the parts, and what role each part plays; What is the part that belongs to your invention? If it is a method invention, it should be explained that the method consists of several steps, what conditions are needed for each step, what is the relationship between the steps and what role each step plays. The basic contents of an invention or utility model shall generally be disclosed in the form of the sum of the necessary technical features. But sometimes, in order to make the technical scope of protection more clear and avoid misunderstanding, it should also include important additional technical features necessary for the invention or utility model, so that people can clearly understand what technical scheme should be adopted to achieve the stated purpose. 6. Beneficial effects This part should clearly explain the beneficial effects of the invention or utility model compared with the existing technology. Generally, the beneficial effects can be reflected by the improvement of output, quality, accuracy and efficiency, the saving of energy consumption, raw materials and working procedures, the simplification of processing, operation, control and use, the treatment or radical cure of environmental pollution, and the emergence of useful properties. The specific requirements are as follows: (1) An invention or utility model can be described by analyzing its structural characteristics or action relationship, explained theoretically or proved by experimental data or their combination, and its beneficial effects cannot be asserted, so it is better to compare with the existing technology; (2) For technical fields such as machinery or electrical appliances, most of them can be explained in combination with structural characteristics and modes of action; (3) When citing experimental data to illustrate the beneficial effects, the necessary experimental conditions and methods should be given. 7. Brief Description of the Drawings The drawings are to express the contents of the invention or utility model more intuitively, and various drawing methods can be used to fully reflect the invention. Such as schematic diagrams, block diagrams, various views, partial sectional views, flow charts, etc. For an application for a patent for invention and all applications for a patent for utility model with drawings in the specification, the drawings shall be given in the specification. The specific requirements are as follows: (1) The title and content of the drawing should be briefly described according to the national standard of mechanical drawing; (2) If there are multiple drawings, all the drawings shall be numbered and explained in turn; (3) The description of the drawings does not need to include the names and details of specific parts in the drawings. *8. Best Mode This part can usually explain the specific embodiment of the invention or utility model in more detail with the attached drawings. It should not be understood as a simple repetition of the contents of the specification. Its purpose is to concretize each technical feature of the claim, so as to concretize the implementation of the invention and fully support the enforceability of the invention or utility model. Generally speaking, this part should describe at least one best mode in detail, and the specific degree of the description should reach the level that ordinary professionals can reproduce their inventions or utility models according to the described content. When describing a specific embodiment, it is not necessary to specify the known technical features, but it is necessary to specify the necessary technical features and additional technical features that distinguish the existing technology, and the relationship between these technical features and their functions and functions. The descriptions of the embodiments and examples shall be consistent with the types of technical solutions claimed in the application. For example, if a product is required to be protected, its realization or example should be one or several best products that reflect the realization of the product; If a method needs to be protected, it should be one or several best implementation methods to realize it.
