Patent drawing requirement

Patent Drawing Requirements in the US and Europe [Latest Guidelines]

April 12, 2021May 24, 2019 by admin

Many inventors first apply for a patent in the US, and then seek the same patent protection in Europe. Both the US Patent and Trademark Office (USPTO) and the European Patent Office (EPO) affirm the importance of drawings to patent applications.

The USPTO says drawings are required if they are needed to understand the subject matter; they are almost always needed. The EPO emphasizes quality: “Good-quality drawings are very important for the correct disclosure of the invention.”

There are many similarities – and some differences – in the rules for patent illustrations in the US and Europe. The full USPTO requirements can be found online at Nonprovisional (Utility) Patent Application Filing Guide.The EPO requirements can be found at Guide for applicants: How to get a European patent (drawings), with links to additional pages on that page.

I want to share the requirements

Requirement of patent drawings

The USPTO requirements are much more detailed than the EPO requirements.

I would recommend You to read the USPTO requirements for patent drawings.

In the following table we highlight the major differences and some of the similarities. When preparing a patent drawing for submission to either authority, please refer to the specific guidelines from the relevant office, linked above. The table is just to give you an idea of what’s different.

Conclusion

Every patent office has very specific requirements for patent drawings. When adapting a patent application from one jurisdiction for submission to another jurisdiction, special care must be taken to make sure the drawings being submitted comply with all the rules of the relevant patent office.

Failure to comply with all of the patent drawing regulations may result in your application being delayed or denied.
