A patent application must include illustrations of the device being patented. These are called patent drawings and they are an integral part of the application process. A patent drawing's purpose is to illustrate the invention and some of its details and characteristics. The patent office actually has some specific requirements as to how the drawings are to be done, and so it is important to work with an experienced patent drawing professional.
In the United States, the patent applicant must provide and create a drawing of the invention whenever the case needs it to understand the invention. This is by law. The drawing should show every single feature of the invention. Design patents can be in color or in black ink. Although black and white drawings are usually needed, color drawings may be needed on rare occasions. Color photographs can be submitted and accepted as a design patent only if the requirements for the black and white photographs are satisfactory. Usually, photographs are not able to demonstrate the inner workings of a mechanism that a patent application must include, though, and so drawings are often better.
Patent drawing characteristics may contain identification of different drawings. This will include the name of the invention itself, the inventor's name, and any other detail you feel should be included. If you are submitting a chemical or math formula patent, this will be in graphic drawing form. However, they are to submit the same requirements as the other drawings. You must also make sure to label each mathematical formula or chemical, use separate brackets if necessary.
When drawing your patent, you should use flexible, white, smooth, matte, and durable paper. It should have a margin standard and various views of the invention. You should also make sure to shade the invention to show the surface elements of the object. Your drawing should also include legends and symbols, the graphical symbols should be used approximately so the reader can decipher what they mean. If you are a drawing a patent for a foreign country, make sure to check the local offices for the patent requirements.
Patent drawings must illustrate sections, elevation, or perspective views. A great example is an exploded view. An exploded view of a separated part will be embraced by a particular bracket, this will allow the viewer to see the relationship of the other parts in relation to the invention. Partial views are usually used to view large machines. The purpose of this is to break up partial views onto a single sheet. Without showing different views, patents will not be able to be fully interpreted.
