How to write the specification of mechanical or electrical patent?

It is very difficult to write a patent for mechanical products, especially when many applicants in China can't explain their inventions clearly. A lot of work of the agent focuses on how to express the applicant's technical scheme clearly, rather than how to write the most appropriate scope of protection. The traditional method of sorting out the ideas of mechanical product patent writing with tree diagram is no longer suitable for the current situation of writing patents with computer office software. Under the modern office conditions, before writing the claims and specifications, the structure of mechanical product patents is analyzed by using spreadsheets, and the technical scheme of mechanical product patents with five attributes of name, structure, material, location and connection mode and three levels of parts, parts and components is assisted, which is clear and simple.

The patent specification is a clear and complete introduction to the structure, technical points and application methods of the invention or utility model, which should include the technical field, background technology, invention content, illustrations, specific implementation methods and other items.

The patent specification has broad and narrow interpretations. In a broad sense, it refers to all kinds of patent specifications published by the Industrial Property Office, the Patent Office and international (regional) patent organizations (hereinafter referred to as the Industrial Property Office). Including the authorization instructions for granting invention patents, inventor certificates, medical patents, plant patents, industrial design patents, utility model patents, supplementary patents or supplementary inventor certificates, supplementary protection certificates, supplementary utility model certificates and their corresponding application instructions. In a narrow sense, it refers to the patent specification granting the patent right.

The main function of patent specification is to disclose new inventions clearly and completely, and to request or determine the scope of legal protection.

Patent specification is a kind of patent literature, which refers to the official document or its publication containing title page, patent claim, specification and other components, describing the content of invention and creation and limiting the scope of patent protection.

The title page in the patent specification is the file part that reveals the basic information of each patent. The basic patent information disclosed on the title page includes: patent application time, application number, applicant or patentee, inventor, name of invention-creation, brief introduction of invention-creation and main drawings (mechanical diagram, circuit diagram, chemical structure diagram, etc. -If any), the classification number of the technical field to which the invention belongs, the time of publication or authorization, the contribution number, the national institution that published the patent document, etc.
