Three Things to Know Before Creating Patent Drawings

A patent is a type of intellectual property. It grants exclusive rights for an inventor to exclude others from making, using or selling an invention for a defined period. Patents are granted for new, useful, and non-obvious inventions, and are territorial, implying that one must apply in each jurisdiction where protection is sought. Patent drawings are a part of the patent document, and it shows the visual embodiment of an invention.

When filing a patent application with the USPTO, you need to include various descriptive information to enable the examiner to determine the patentability of your invention. As the saying goes, a picture is worth a thousand words, including patent drawings, will help the examiner appropriately learn about the product. These drawings should depict all aspects of the invention which are covered in the claims.

Patent drawings are a key method to effectively communicate your invention’s unique features and expedites the process of inspection, evaluation, and approval. The USPTO has listed general guidelines for patent drawings which you need to strictly adhere to.

The margin should be uniform across the entire document. The margins must be 2.5 cm across the top, 2.5 cm along the left side, 1.5 cm along the right side, and 1.0 cm across the bottom. Vertical drawings are preferred over horizontal ones, and only one side of a sheet must be used.

Production Options

You can use CAD (computer-aided design) software for producing the 2D drawing views that USPTO requires based on a 3D model. It allows you to effectively create the drawings and meet the standards and specifications of the patent office. Besides the CAD platform, you can also use a low-cost alternative, like modeling software which also has free versions available. However, ensure that drawings are accurate and error-free. The lowest cost option is manual patent drawings. You need to appropriately follow the drafting standards to produce the hand-drawn set.
