What is an extract of an original document in patent assignment submissions?

An extract of an original document refers to a portion or summary of the original assignment document that contains the essential information required for recording. Both 37 CFR 3.24(a) and (b) state that “Either a copy of the original document or an extract of the original document may be submitted for recording.”

When submitting an extract:

• Ensure it includes all relevant assignment details.
• The extract must meet the same format requirements as a full copy.
• It should be clear that the extract represents the key elements of the original document.

Using an extract can be beneficial when the original document contains confidential information not necessary for the assignment record.
