What are the requirements for paper submissions of patent assignment documents?

For paper submissions of patent assignment documents, the following requirements must be met:

• Submit either a copy of the original document or an extract of the original document.
• Use only one side of each page.
• Paper size must be either 8.5″ x 11″ or A4, with a 1-inch margin on all sides.
• Use flexible, strong white, non-shiny, and durable paper.

As stated in 37 CFR 3.24(b): “For paper submissions, the paper used should be flexible, strong white, non-shiny, and durable.” This ensures that the document can be properly recorded and stored by the USPTO.
