How To Make a Patent Drawing

In order to patent any type of invention, the government insists on receiving a clear drawing of the invention before the patent is given. All drawings must be extremely specific showing intricate details of their inventions.

The Patent Office has specified the size of drawing sheets, margins, and how there are numbered and referred to depending on the size of the invention. It also should be drawn to scale, however, if it is not possible, it is important to include a measurement scale. There are also a few ways that the task of creating a patent drawing can be completed.

Patent Office Standards require that, unless deemed necessary, all drawings be done in black. It is only after approval from the office that the inventor is able to use color. In order to be granted the request, the inventor must petition the request giving a reason as to why color is needed. They are also required to send a black and white drawing along with the color drawing proving their reason for the use of color.

For those who have an artistic gift, a patent drawing can be done freehand. Every detail must be drawn, so it is imperative that the drawing is done with the invention in view and not just by memorization. Use a pencil for the first draft to avoid making permanent mistakes. Go over it with black ink and erase the pencil drawing. Once the drawing is complete, photocopy it and check that the drawing meets the Patent Office standards.

If freehand seems like an impossible feat, it may be a good idea to photocopy the invention and trace it. It is still important to include the intricate details so taking pictures from every angle and tracing separate drawings is important. Be sure to take the photo against a solid white or black background to help with the accuracy of the drawing.

For those who cannot rely on their artistic ways, computer aid design (CAD) was created to help. While using this program is not simple and may require some training - which you can easily get through online art and design universities - it allows the inventor to sketch or trace the invention using the computer. It is still important to keep the invention in front of you for reference. CAD also automatically generates measurements for comparison.
