A patent application or patent may contain drawings, also called patent drawings, illustrating the invention, some of its embodiments (which are particular implementations or methods of carrying out the invention), or the prior art. The drawings may be required by the law to be in a particular form, and the requirements may vary depending on the jurisdiction.

From 1790 to 1880 in the US, patent models were required. A patent model was a scratch-built miniature model no larger than 12" by 12" by 12", approximately 30 cm by 30 cm by 30 cm, that showed how an invention works. Some inventors still willingly submitted models at the turn of the twentieth century. In some cases, an inventor may still want to present a "working model" as an evidence to prove actual reduction to practice in an interference proceeding. In some jurisdictions patent models stayed an aid to demonstrate the operation of the invention. In applications involving genetics, samples of genetic material or DNA sequences may be required.

The United States patent law was revised in 1793. It stated that the Commissioner of the USPTO could ask for additional information, drawings, or diagrams if the description is not clear. By then, the rate of patent grants had grown to about 20 per year and the time burden on the Secretary of State was considered to be too burdensome. Patent applications were no longer examined. Patents were granted simply by submitting a written description of an invention, a model of the invention, if appropriate, and paying a fee of $30 then, and now $1000 in 2006 US dollars.

In utility and design patent applications, drawings can be in black ink or color. Black and white drawings are normally required. On rare occasions, color drawings may be necessary as the only practical medium by which to disclose the subject matter sought to be patented in a utility or design patent application or the subject matter of a statutory invention registration.

Black and white photographs are not ordinarily permitted in utility and design patent applications, unless this is the only practicable medium for illustrating the claimed invention. For example, photographs of electrophoresis gels, blots, autoradiographs, cell cultures, histological tissue cross sections, animals, plants, in vivo imaging, etc. Color photographs can be accepted in utility and design patent applications if the conditions for accepting color drawings and black and white photographs have been satisfied.

Unlike utility patents, applications for design patents rely fully on the drawings. According to USPTO guidelines, “the drawing disclosure is the most important element of the application,” and the drawings in design patent applications “constitute the entire visual disclosure of the claim.” In well-executed drawings “nothing regarding the design sought to be patented is left to conjecture.

Patent drawing features can contain the following features:

1 Identification of drawings: includes the title of the

2 invention, inventor's name, and application number.. etc.

3 Graphic forms in drawings. Chemical or mathematical formulae, tables, and waveforms may be submitted as drawings and are subject to the same requirements as drawings. Each chemical or mathematical formula must be labeled as a separate figure, using brackets when necessary, to show that information is properly integrated.
4 Type of paper: generally flexible, strong, white, smooth, matte (non-shiny), and durable.
Size of paper: Must be the same size. In US, choose one of either: DIN size A4 or (81⁄2 by 11 inches).

5 Some kind of Margin standard.

6 Views. The drawing must contain as many views as necessary to show the invention. The views may be plan, elevation, section, or perspective views.

8 Front page view
9 Scale: large enough to show the mechanism
10 Shading: aids in understanding the invention used to indicate the surface or shape of spherical, cylindrical, and conical elements of an object.
