1. Attached drawings of the instruction manual
The drawings in the instruction manual should be drawn with drawing tools, including computer and black ink. The lines shall be uniform, clear and deep enough, and shall not be colored or altered. Engineering blueprints shall not be used.
The section line in the section drawing shall not hinder the clear identification of the reference mark line and the main line.
How many pictures can be drawn on a piece of paper? A master plan can be drawn on several drawings, but it is necessary to ensure that the drawings on each drawing are independent. When all the drawings are combined to form a complete master plan, they do not affect each other's clarity. There should be no borders around the drawings that have nothing to do with the drawings. If there are more than two attached drawings, they shall be numbered with Arabic numerals, and the word "Figure" shall be added before the number, as shown in Figure 1 and Figure 2. This number should be marked directly below the corresponding drawing.
The attached drawings should be drawn as vertically as possible on the drawings and clearly separated from each other. When the horizontal dimension of parts is obviously larger than the vertical dimension and must be arranged horizontally, the top of the drawing should be placed on the left side of the drawing. When there are more than two drawings on a page, and one of them has been arranged horizontally, the other drawings on the page should also be arranged horizontally.
Reference numerals shall be numbered with Arabic numerals. Reference symbols not mentioned in the text of the specification shall not appear in the drawings, and reference symbols not appearing in the drawings shall not appear in the text of the specification. The reference numerals indicating the same parts in the application documents shall be consistent.
The size and clarity of the attached drawings should ensure that when the drawings are reduced to two thirds, all the details in the drawings can still be clearly distinguished to meet the requirements of copying and scanning.
The same drawing should be drawn at the same scale, and a local enlarged drawing can be added to make a part show clearly. The appended drawings shall have no other comments except necessary words. The text in the appended drawings should be Chinese, and the original text can be marked with brackets if necessary.
The flow chart and block diagram should be attached as drawings, and the necessary words and symbols should be given in their boxes. Generally, photographs are not allowed to be used as drawings, but under special circumstances, such as showing metallographic structure, tissue cells or electrophoresis maps, photographs can be used as drawings and attached to the drawings.
The appended drawings of the specification shall be numbered in Arabic numerals.
2, abstract the appended drawings
Where there are drawings in the specification, the applicant shall submit a drawing that best illustrates the main technical features of the technical scheme of the invention as an abstract. The attached drawings shall be one of the attached drawings in the specification. If the applicant fails to submit the appended drawings, the examiner may notify the applicant to make corrections, or appoint a person ex officio, and notify the applicant. If the examiner confirms that there are no suitable abstract drawings to indicate, he may not require the applicant to make corrections.
Where the appended drawings of the abstract submitted by the applicant obviously fail to explain the main technical features of the technical scheme of the invention, or the appended drawings of the abstract submitted are not one of the drawings of the specification, the examiner may notify the applicant to make corrections, or designate one ex officio, and notify the applicant.
The size and clarity of the attached drawings shall ensure that all the details in the drawings can still be clearly distinguished when the drawings are reduced to 4 cm ×6 cm.
Abstract can contain the chemical formula that best illustrates the invention and can be regarded as an abstract diagram.
3. Requirements
A claim may contain a chemical formula or a mathematical formula, with tables but no illustrations when necessary.
In addition: the description of utility model patent must have attached drawings.
