The provisional patent application process is an essential step in securing a patent for your invention. It allows inventors to establish a priority date for their invention and provides a year to prepare a complete patent application. Provisional patent applications do not require formal patent claims or an oath or declaration, but they do require clear and complete provisional patent drawings.


Provisional Patent Drawing Requirements

Provisional patent drawings are essential to the patent application process. They provide a visual representation of your invention and its various components. The drawings must be clear, concise, and meet the following requirements:

Scale and Dimensions

Provisional patent drawings should be drawn to scale, indicating the exact dimensions of the invention. The scale should be consistent throughout all the drawings, and each drawing should be labeled with the same scale.

Neatness and Clarity

The drawings should be neat and clear, with every line and character drawn with accuracy and precision. The drawings should also be free of any unnecessary information or markings.

Numbering and Labeling

Each drawing should be labeled with a brief title and a number that corresponds to the description in the written part of the provisional patent application. Additionally, each drawing should have a reference character that points to every part of the invention being described.


Provisional patent drawings should include as many views as necessary to fully disclose the invention. These views should include front, back, right and left sides, top, and bottom.


The drawings should be clear and legible and easily reproduced. They should be suitable for printing or reproduction in a variety of sizes, including reducing the drawings to fit onto a single sheet of paper.

Patent Drawing Services

While provisional patent drawing requirements may seem straightforward, it can be challenging to create accurate and high-quality drawings without professional assistance. Patent drawing services specialize in creating drawings that meet all the requirements for a successful patent application.

Benefits of Patent Drawing Services

There are several benefits to using patent drawing services, including:

Experience and Expertise

Patent drawing services employ experienced and skilled draftsmen who understand the complex requirements of patent drawings. They have extensive knowledge of the US Patent and Trademark Office’s (USPTO) requirements and can create drawings that meet all the necessary guidelines.

Accuracy and Precision

Professional patent drawing services use the latest computer-aided design (CAD) software to ensure that the drawings are accurate and precise. They can also make changes to the drawings quickly and easily, reducing the risk of errors or omissions.


Using a patent drawing service can be cost-effective compared to hiring an in-house drafter or attempting to create the drawings yourself. Professional drawing services typically charge a flat fee for a set number of drawings, reducing the risk of unexpected costs or fees.


Creating high-quality provisional patent drawings can be time-consuming, especially if you are not familiar with the requirements. By outsourcing the task to a professional drawing service, you can save valuable time and focus on other aspects of the patent application process.

Utility Patents vs Design Patents

It is essential to note the difference between design patents and utility patents when it comes to provisional patent drawing requirements. Design patents protect the visual and ornamental characteristics of an invention, while utility patents protect the functional aspects.
