US National Stage Application: The Basics

Let’s begin with the basics of filing a national stage application in the US based on an international PCT application.

When is the US National Stage Deadline?

The deadline is 30 months from the priority date. If the deadline has already passed, it may still be possible to file a late US national stage application if the delay was unintentional.

What are the USPTO filing fees for a national stage application?

The minimal USPTO filing fees for a national stage application amount to $740 for a small entity (double for a large entity). This minimum does not include additional fees that may be required, such as for excess claims, multiple dependent claims, application size, late filing of signed inventor declarations, etc. To prevent abandonment, the bare minimum that must be paid with the initial entry is the basic national stage fee which is $140 for a small entity.

What is our initial filing cost estimate for a US national stage application?

Our firm charges a flat attorney’s fee of $570 for filing a US national stage application, not including an IDS or assignment. Therefore, our standard quote for filing a US national stage application for a small entity is $1,310 ($570 + $740 USPTO fee). Additional fees may apply for filing an IDS, assignment or a Preliminary Amendment. Since our service fees are flexible, please inquire about a discount if you or your clients are cost-sensitive.

US National Stage Checklist

Here’s a checklist of basic requirements for a US national stage application:

  • copy of PCT application (required upfront)
  • USPTO fees (basic national stage fee required upfront)
  • whether the applicant is a small entity or large entity (required upfront)
  • names and addresses of inventors and applicant (required upfront; typically available from published PCT application)
  • signed inventor declarations (may be submitted after initial filing)
  • any PCT amendments under Article 19 and/or Article 34 (may be submitted after initial filing)
  • a signed Power of Attorney for the US representative (may be scanned; original not required)
  • English translation of PCT application (may be submitted after initial filing)
  • English translation of any amendments (may be submitted after initial filing)
  • prior art information for filing an Information Disclosure Statement (may be submitted after initial filing)

National Stage Entry from Foreign PCT Application

PCT Application In Foreign Language

If the PCT application was filed in a foreign patent office with a non-English specification, an English translation must be filed in the US national stage application. To avoid a surcharge under 37 CFR § 1.492(i) ($70 for a small entity as of post date), an English translation of the international application should be included with the initial filing.

If an applicant does not have enough time to provide an English translation by the 30-month national stage deadline, a copy of the PCT application may be initially filed. Shortly after the national stage entry, the applicant will receive a Notification of Missing Requirements under 35 USC § 371 setting forth a 2-month deadline (or 32 months from priority date, whichever is later) for submitting an English translation of the international application.

Multiple Dependent Claims

If the PCT application contains multiple dependent claims, an initial determination should be made as to whether the multiple dependent claims are in proper format, namely, that no multiple dependent claim depends upon another multiple dependent claim. If the international application contains improper multiple dependent claims, those claims must eventually be amended or deleted.

Proper multiple dependent claims may be kept in a US national stage application, but doing so will incur at least a USPTO multiple dependent claim fee of $390 for a small entity, plus fees for any excess claims above 20 that may result from a final count. Therefore, a business decision should be made before the initial filing as to whether or not to keep proper multiple dependent claims.

Preliminary Amendment

Foreign PCT applications tend to have a number of issues best resolved by filing a Preliminary Amendment concurrently with the initial filing or shortly after entry into the US. Avoiding the $390 USPTO multiple dependent claim fee plus any excess claims fees may alone justify filing a Preliminary Amendment. Other factors that may warrant a Preliminary Amendment may include:

  • Figures that contain unclear drawings or non-English text
  • Multiple dependent claims
  • Abstract exceeding 150 words
  • Total claims in excess of 20
  • Independent claims in excess of 3

National Stage Entry from US PCT Application

If your PCT application was filed with the USPTO, you have the option of filing a national stage application in the US. Chances are that you may have already filed a US non-provisional application and the PCT application was filed to reserve your rights to file in foreign countries. Nonetheless, you also have the option of filing another non-provisional in the US by way of national stage entry. Therefore, think of this option as a continuing application to pursue claims different than those that may exist in a co-pending US application.
