We provide certified and non‑certified copies of USPTO Non‑Patent Literature (NPL) documents exactly as they appear in the official patent file history. These are the precise documents submitted during prosecution and preserved in the file wrapper — not alternate versions sourced from publishers, databases, or online archives.
Our service ensures you receive the exact NPL reference(s) submitted within the USPTO patent file histories.
What We Deliver
Exact File‑Wrapper NPL Documents
Every NPL document we provide is retrieved directly from the patent’s official file history. You receive the same version submitted during prosecution, including all pages, attachments, and supplemental materials.
Non‑Certified Copies
A complete, accurate PDF reproduction of the NPL document as it appears in the USPTO file wrapper.
Certified Copies
A USPTO‑certified reproduction of the NPL document, suitable for any matter requiring verified authenticity or evidentiary use.
How to Request NPL Documents
Provide the following:
- Patent or application number
- The specific NPL citation(s) needed, or all NPLs cited on the face of the patent
- Any additional identifying details (title, author, publication year, etc.)
We retrieve the NPL documents directly from the USPTO archives in person and deliver complete PDF copies. Most orders are completed within 24–48 hours.
Fees for obtaining NPLs are based on time spent at the USPTO along with the number of pages. It is best to request a timeframe and quote when placing orders for NPL documents — we will get back to you quickly.
Why File‑Wrapper NPL Copies Matter
Professionals requesting NPL documents already understand their significance. The version submitted to the USPTO is often different from versions available through publishers or online sources. Only the file‑wrapper copy reflects what the examiner actually reviewed and relied upon.
DPS Files Inc. ensures you receive that exact version — certified or non‑certified, depending on your needs.
