Information on drawing requirements is based substantially on 37 CFR § 1.84.

Black and white drawings are normally required. India ink, or its equivalent that secures black solid lines, must be used for drawings. For nonprovisional utility applications, the “sheets” of drawings should be contained in an electronic document in PDF format filed via EFS-Web together with the other application documents in PDF format. Drawings made by hand should be scanned into PDF format for filing via EFS-Web. The following margins are required:

  • On 21.6 cm by 27.9 cm (8 1/2 by 11 inches) drawing sheets, each sheet must include a top margin of at least 2.5 cm (1 inch), a left-side margin of at least 2.5 cm (1 inch), a right-side margin of at least 1.5 cm (5/8 inch), and a bottom margin of at least 1 cm (3/8 inch) from the edges, thereby leaving a sight (the usable surface) no greater than 17.6 cm by 24.4 cm (6 15/16 by 9 5/8 inches).

On 21 cm by 29.7 cm (DIN size A4) drawing sheets, each sheet must include a top margin of at least 2.5 cm (1 inch), a left-side margin of at least 2.5 cm (1 inch), a right-side margin of at least 1.5 cm (5/8 inch), and a bottom margin of at least 1 cm (3/8 inch) from the edges, thereby leaving a sight no greater than 17 cm by 26.2 cm.

Drawings shall be executed in durable, black, sufficiently dense, and dark, uniformly thick, and well-defined, lines and strokes without colorings.

  1. Cross-sections shall be indicated by oblique hatching which should not impede the clear reading of the reference signs and leading lines.
  2. The scale of the drawings and the distinctness of their graphical execution shall be such that a photographic reproduction with a linear reduction in size to two-thirds would enable all details to be distinguished without difficulty.
  3. When, in exceptional cases, the scale is given on a drawing, it shall be represented graphically.
  4. All numbers, letters, and reference lines, appearing on the drawings, shall be simple and clear. Brackets, circles, or inverted commas shall not be used in association with numbers and letters.
  5. All lines in the drawings shall, ordinarily, be drawn with the aid of drafting instruments.
  6. Each element of each figure shall be in proper proportion to each of the other elements in the figure, except where the use of a different proportion is indispensable for the clarity of the figure.
  7. The height of the numbers and letters shall not be less than 0.32 cm. For the lettering of drawings, the Latin and, where customary, the Greek alphabets shall be used.
  8. The same sheet of drawings may contain several figures. Where figures on two or more sheets form in effect a single complete figure, the figures on the several sheets shall be so arranged that the complete figure can be assembled without concealing any part of any of the figures appearing on the various sheets.
  9. The different figures shall be arranged on a sheet or sheets without wasting space, preferably in an upright position, clearly separated from one another. Where the figures are not arranged in an upright position, they shall be presented sideways with the top of the figures at the left side of the sheet.
  10. (The different figures shall be numbered in Arabic numerals consecutively and independently of the numbering of the sheets.
  11. Reference signs not mentioned in the description shall not appear in the drawings, and vice versa.
  12. The same features, when denoted by reference signs, shall, throughout the international application, be denoted by the same signs.
  13. If the drawings contain many reference signs, it is strongly recommended to attach a separate sheet listing all reference signs and the features denoted by them.
