Patent Drawings and Invention Illustrations, What Do You Require?

Patent drawings aren’t similar to the general drawings we see in daily life. Patent illustrations aren’t expected to simply show what innovation looks like. 

For utility patents inventions, patent illustration should be explicit and detailed enough that somebody “proficient in the art” can build the item depicted or utilize the strategy disclosed by the patent.

Patent drawings of a physical object need to completely show its appearance. For most 3D objects, this will mean at any rate six perspectives: top, bottom, front, back, left, and right. Other perspectives may likewise be expected to make things clear to the patent examiner. For instance, perspective views, sectional views, or exploded views might be suitable. If the invention has moving parts, it could be important to show how the parts are organized when the machine is being used. Shading might be expected to show contours and various surfaces.

The US Patent Office has quite certain standards about what patent drawings can and can’t include, and neglecting to keep these guidelines can get a patent application dismissed – wasting time and potentially missing out on patent rights if another innovator beats you to the Patent Office.

Computer-Aided Design (CAD) and Patent Drawings

Previously, patent illustrations could be ornate works of art, made by hand with superior handwriting. Nowadays, patent drawings are quite often made utilizing CAD – computer-aided design. CAD software is utilized by architects, drafters, and others to create correct drawings and technical illustrations. Sometimes, CAD files can be taken care of straightforwardly into 3-D printers or other manufacturing devices to directly make actual objects.

Since the standards for making drawings to accompany a patent application are so detailed and explicit, not just anyone with CAD software can make patent illustrations accurately. To maximize the chances that your patent will be granted the FIRST time you submit your application, it’s a smart thought to work with an expert, experienced patent drawings company.

If you are going to file a patent application you should have drawings to include in the patent application, yet patent drawings are not the only kind of “drawings” that an innovator ought to consider. Patent drawings are excellent for a patent application, however, they don’t generally do the invention justice if you are attempting to catch the attention of a prospective licensee.

Just expressed, patent drawings and different kinds of invention drawings, such as 3D renderings and photorealistic virtual prototypes fill various needs.

The patent drawing contains reference numerals that are utilized by the patent lawyer in the detailed description of the patent application, and this is an absolutely fine illustration to incorporate in a patent application. Yet, recall, the purpose of the detailed description is to explain what is displayed in the figures. However vital as patent drawings are they simply do not catch the consumer product with almost a similar effect as a 3D rendering does.

With patent drawings, you can display exploded views that allow you to determine how the pieces and parts fit together. This facilitates the patent lawyer to explain how to make the innovation bit by bit, which is not only a smart thought but a necessity for any patent application. Such exploded views perpetually center around the interior, not the outer.

A patent applicant is needed to furnish in any event one patent drawing of the invention at whatever point the innovation is equipped for illustration via a drawing. A patent drawing is quite often required, and regardless of whether it is not needed, you ought to have at least one patent drawing.

Why take the risk when the patent drawings are required by the patent examiner?

Patent Drawings are required for a patent application. If you do not submit the patent drawings in the original filing of a non-provisional patent application you are not granted a filing date, which can be disastrous. Thus, the innovator ought to comprehend the patent drawing requirement in this way: The possible time patent drawings are not needed is the point at which the innovation associates a chemical compound, composition, or method.

Detailed drawings are worth 1,000 words, if not more. Because if you incidentally avoid something out of the written disclosure, a drawing you submit may save you over the long run, given it is detailed enough to convey nuanced information about your invention. Since the detail of the patent drawing is the thing that saves you, having an expert patent illustrator is quite wise. Undoubtedly, the most ideal approach to expand the extent of any application is to file a patent application with numerous, detailed, and proficient drawings. The advantage received from proficient patent illustration is definitely worth the investment.

Get initial illustrations that can be utilized for various purposes

It would make the most sense since it is more affordable, and you can if you work with somebody that does the 3D rendering.

From the 3D CAD renderings, a photorealistic virtual prototype is made, which would then be able to be marked and added to the sell sheet. By following this cycle the 3D CAD renderings can be output as line drawings that make extraordinarily great patent drawings, at any rate for a provisional patent application where the focus is disclosure. The Patent Office won’t ever analyze a provisional patent application, so none of the demanding patent drawing rules will be enforced against provisional patent drawings. Once the 3D CAD renderings are done as many drawings as you need can be output, from various rotated viewpoints, as well as a variety of close-up views.

Patent drawings should show each element of the innovation indicated in the claims, and for a non-provisional patent application, they are needed to be in a specific form. The Patent Office determines the size of the drawing sheet on which the illustration is made, the type of paper, the margins, and numerous other hyper-technical details relating to the making of the drawings, including shading and size of the text if present. The reason for indicating the guidelines in detail is that the drawings are printed and distributed in a uniform style when the patent issues and the drawings should likewise be to such an extent that they can be promptly perceived by people utilizing the patent descriptions. Yet, none of these principles apply to provisional patent drawings, and the focal point of a provisional patent application is to demonstrate the entirety of the innovation. Consequently, the 3D CAD rendering turns into a point of convergence for permitting the innovator to acquire all of the types of illustrations they will require initially.

As you push ahead to photorealistic virtual prototyping, which is somewhere in the range of 10 to 100 times less expensive than building up a single real-world prototype, the making of the “sell sheet” becomes critical for individuals who are hoping to license their invention. 


It is currently conceivable to get a filing date on a nonprovisional patent application without a drawing being present at the time of filing. This new guideline doesn’t change the truth that in any event a single drawing is needed when necessary. In this way, filing a patent application without a drawing is massively unsafe and ought to be avoided. If you attempt and add a drawing after filing, you will likely be kept from doing so because notwithstanding the way that a drawing is not needed to get a filing date you still cannot add another new matter after you file a patent application. Adding drawings will normally add material, which is disallowed. The Patent Office has cautioned patent candidates that it remains best practice to file with drawings.
