Certified Patent Document Translation

A PCT national phase deadline or a court filing needs your patent document in English, or your U.S. patent needs to go the other way for a foreign filing. Cloud Translate turns that around fast: a certified translation at $18 per page, with a technical-background translator and a 100% acceptance guarantee, so your deadline doesn't slip.

Matched to Your Technology, Not Just Your Language Pair

Certified translations accepted by USPTO and foreign patent offices

Translators matched to your invention's technical field

100% acceptance guarantee, free revisions if rejected

24–48 hour standard turnaround, with expedited options for tight deadlines

Every translation double-checked for claim numbering and cross-reference accuracy

Claims, Specification, Abstract, and Drawings All Have to Cross-Reference Correctly

A patent application includes an abstract, a specification or description, numbered claims (often with dependent claims that reference earlier claim numbers), and drawings with reference numerals, and a PCT international application, a granted patent, and a published application each carry a slightly different legal status. We translate the complete document and preserve claim numbering and reference numerals exactly, so every cross-reference in the translated version still points to the right place.

When Patent Documents Need to Be Translated

A translated patent document usually comes up when a filing crosses a language barrier, or when a foreign patent becomes evidence in a dispute. Two of the most common situations:

Government Filings

Court & Legal Proceedings

Certified Translation and USPTO National Phase Requirements

These terms get used interchangeably, but they aren't the same thing, and the receiving agency usually cares about the difference:

Certified translation: A signed Certificate of Accuracy from the translator attesting the translation is complete and accurate. This is what USCIS, most U.S. courts, and most U.S. government agencies require.

Notarized translation: A notary public witnesses the translator sign the Certificate of Accuracy and applies their official seal. Notarization verifies the identity of the signer, not the accuracy of the translation. Some courts, banks, and foreign consulates specifically require this.

Sworn translation: In many European and Latin American countries, only a translator who has taken an oath before a court is authorized to produce a legally valid translation. If your document is going to a country outside the U.S., check whether it requires a sworn translator rather than a U.S.-style certified translation.

USPTO generally requires a certified translation of a foreign-language priority document for PCT national phase entry, but not notarization, for most filings. Requirements vary by patent office and by court if the document is used in litigation, so confirm with your patent attorney or tell us the office or proceeding and we'll advise.

Sample certified translation documents

Your certified translation is delivered as a digital PDF with an official Certificate of Translation Accuracy, signed and stamped by the translator and Cloud Translate. We apply basic formatting to keep it readable, but we do not replicate the design of your source document.

Included With Every Patent Translation

  • Claims, abstract, specification, and drawing reference numerals translated exactly, with claim numbering and cross-references preserved
  • A translator matched to your invention's technical field, in addition to patent and legal terminology expertise
  • A signed Certificate of Accuracy naming the translator and their qualifications
  • Confidential handling of unpublished, pending applications, treated as trade secrets, with our own NDA available on request before we start
  • A print-ready PDF by email, with notarized hard copies available by mail

How It Works

From upload to certified PDF in four steps.

  1. Upload the patent application, claims, specification, and drawings you need translated.

  2. Get a free quote and choose standard, expedited, or same-day delivery, we treat unpublished, pending applications as confidential trade secrets and can sign an NDA before starting if your counsel requires it.

  3. A translator with relevant technical background in your invention's field, mechanical, chemical, biotech, software, or otherwise, completes the translation alongside patent-specific legal terminology; a second linguist checks claim numbering and reference numerals for consistency before delivery.

  4. Review your translation, request any free revisions, and receive the final certified PDF, with notarization and hard-copy mail available.

The translation matched our birth certificate exactly, and it was accepted by USCIS on the first try. Turnaround was faster than I expected.

Questions & Answers

Frequently asked questions.

The questions people ask before ordering a patent document translation.

Read every question →

How long does a certified patent document translation take?

Most certified patent translations are completed within 24–48 hours for standard applications. Expedited and same-day delivery are available for an additional fee when you're working against a PCT national phase entry deadline or a court filing date.

Will my translated patent document be accepted by USPTO or a foreign patent office?

Yes, when the requirement is a certified translation. Every translation includes a signed Certificate of Accuracy. Because requirements vary by patent office, tell us where it's being filed and we'll confirm exactly what's needed.

Do you have translators with technical or scientific backgrounds in my field?

Yes. We assign a translator with relevant technical background, mechanical, chemical, biotech, software, or another field matching your invention, in addition to experience with patent and legal terminology, rather than a generalist translator for every patent.

Can the inventor or an employee at our company translate the patent instead?

For an internal review, that may be fine. But for a formal filing or litigation submission, most patent offices and courts expect a translation from an independent third-party translator, not the inventor or an employee with a stake in the patent.

Is my unpublished patent application kept confidential?

Yes. We treat pending, unpublished applications as trade secrets, limit access to the translators and reviewers working on your order, and can sign your own confidentiality agreement before we start if your counsel requires it.

Do I need a notarized translation of my patent document?

Most patent office filings, including USPTO national phase entry, require a certified translation but not notarization. Some courts or foreign agencies request notarization instead. Tell us where it's going and we'll confirm before you order.

Who certifies a patent document translation?

A professional translator with relevant technical and patent terminology experience completes the translation and signs a Certificate of Accuracy attesting that it is a complete and accurate rendering of the original document.

How much does a patent document translation cost?

Standard certified translation is $18 per page. Expedited (rush) translation is $28 per page. Notarization is available as an add-on for $9 per document.
