(1) writing of the request: fill in according to the contents and tips of the form.
(2) Writing of instructions: discuss the steps one by one according to the name of the invention or utility model, technical field, background technology, purpose of invention and creation, technical scheme, beneficial effects, further explanation with attached drawings and specific implementation methods.
(3) Writing of claims: independent claims and dependent claims should be divided based on the specification. When there are multiple claims, they should be numbered in Arabic numerals in sequence. In general, the first claim is an independent claim, and the rest are dependent claims. If the technical features in the independent claims need to be further defined, they are dependent claims.
1. Independent claims are usually divided into prefaces and features:
A. Prefaces indicate the title of the subject to be protected and the necessary technical features with the existing technology;
B. in the characteristic part, use the phrase "characterized by ..." or similar words to indicate the unique technical characteristics different from the existing technology. Together with the characteristic part, the preamble part constitutes the scope of the patent application.
2. The writing of subordinate claims includes a quoting part and a limiting part:
A. The quoting part: the number of the quoted claim and its subject name are stated;
B. limited part: specify the additional technical features to be protected.
(4) Drawing of drawings in the specification: A patent for utility model must have drawings; Invention patents generally have drawings, but if only words are enough to clearly and completely describe the technical scheme, there may be no drawings.
1. The attached drawings can take many forms:
A. Various views can be used to reflect the shape and structure of products for inventions in the mechanical field.
B. Inventions and creations in the field of electrical appliances can be circuit diagrams, block diagrams and schematic diagrams;
C. For inventions in the chemical field, the chemical structural formula can be used as the attached figure;
D. for the method invention, the attached drawing may be a process flow chart showing each step of the method.
2. Requirements for the attached drawings:
A. The attached drawings shall conform to the national standards for mechanical drawing, that is, drawing tools (or computer drawing) shall be used, and the lines shall be uniform and clear, and the drawings shall not be colored. There shall be no border around the drawings, and pencil pens shall not be used for drawing, but the attached drawings need not be marked with scale and size data.
B. The size and clarity of the attached drawings shall ensure that when the drawings are reduced to 4×6 cm, all details in the drawings can still be clearly distinguished and meet the requirements of photographic plate making;
C. Several drawings of the same patent application can be drawn on the same piece of paper with a special format, numbered sequentially with Arabic numerals, and expressed in the form of "Figure ×××".
D. If the same patent application has multiple pages of drawings, Arabic numerals shall be used to continuously write the page numbers;
e. The reference marks used in the same patent application must be consistent, and the marks not mentioned in the specification shall not appear in the drawings;
F. The attached drawings should not contain other notes except necessary words.
(5) Writing of the abstract of the specification:
A. The abstract shall specify the technical field to which the invention or utility model belongs, the technical problems to be solved, the main technical features and uses. For the product applying for utility model, the characteristics of its shape, structure or combination shall be written. It should not be written as an advertisement or a simple product function introduction;
B. The abstract should not be titled and can be written continuously;
C. for inventions in the chemical field, the abstract may include a chemical formula that best describes the characteristics of the invention among the applied chemical formulas. Abstract can also include mathematical formula or reaction formula.
D. The abstract need not be segmented, and the full text should not exceed 2 words.
(6) Drawing of abstract drawings: If there are drawings in the specification, a drawing which can best explain the technical characteristics should be submitted as the abstract drawing, and the size and clarity of the drawing should ensure that all details in the drawing can be clearly distinguished when the drawing is reduced to 4×6 cm.
