USPTO Notice to Correct Application Papers -Patent Law

What is a Notice to Correct Application Papers?

The notice means United States Patent and Trademark Office (USPTO) has found an issue with the  filing (the way the paperwork looks, or what’s included in, or a clarification is needed your application) and is asking you to correct them and resubmit. Your time in which to do so is limited, if you want to retain the original filing date (and we know you want to keep that earliest date!)

A Notice to Correct Application Papers can be issued anytime during the pendency of a Nonprovisional Patent Application, but it will usually be sent shortly after your Patent Application is filed.

Your Filing May Be Considered “Informal”

Section 506 of the USPTO Manual of Patent Examining Procedure reads:


An application is informal if it is typed on both sides of the paper, or is not permanent, legible, or reproducible. If such informalities are timely corrected, the application is given the filing date on which the original informal papers were filed.

OPAP accords a filing date, as of the date indicated by the “Office Date” stamp (see MPEP 505), to application papers which include a specification containing a description and at least one claim (nonprovisional applications filed under 37 C.F.R. 1.53(b) prior to March 18, 2013 and design applications), and a drawing, if necessary under 35 U.S.C. 113 (first sentence) and 37 C.F.R. 1.53(b), but are informal because they do not comply with the rules or notices. In such applications, OPAP will send a Notice (e.g., Notice to File Corrected Application Papers) requiring correction of the informality. Failure to correct the informality within the specified time results in abandonment of the application.”

Case Study: The Situation

  • Our company’s Dallas R&D department filed a US Provisional Patent Application for one the company’s electromechanical gadgets. Before the expiration of the Provisional Patent Application, our company filed a US Nonprovisional Patent Application claiming the benefit of the US Provisional Application. Our in-house patent attorney located at our principal office in Houston had previously used this strategy to procure several US Patents.
  • Among other things, the Nonprovisional Patent Application included: an Abstract, Claims, a Specification and black and white line Drawings.
  • After filing the Nonprovisional Application, the USPTO generated a Notice to File Missing Parts because one of the inventor’s Declarations was missing from the as-filed Application. After receiving the Notice to File Missing Parts, our in-house counsel timely supplied the missing inventor’s Declaration to the USPTO.
  • Over the subsequent three and one-half years, our in-house counsel argued back and forth with the Patent Examiner, and eventually, the Examiner issued a Notice of Allowance for our electromechanical gadget Nonprovisional Patent Application.
  • More than a month after receiving the Notice of Allowance, the Examiner issued a Notice to File Corrected Application Papers.

Our Company’s Notice to Correct Application Papers

The Notice, in part, read:

“Notice of Allowance Mailed

This application has been accorded an Allowance Date and is being prepared for issuance. The application, however, is incomplete for the reasons below.

Applicant is given two (2) months from the mail date of this Notice within which to respond. This time period for reply is extendable under 37 CFR 1.126(a) for only two additional MONTHS.

The informalities requiring correction are indicated in the attachment(s). If the informality pertains to the abstract, specification (including claims) or drawings, the informality must be corrected with an amendment in compliance with 37 CFR 1.121…

Figure numbers are missing or duplicated. FIGS 21-24.”

Notice to Correct Application Papers: Our Next Steps

Since our company had never received a Notice to Correct Application Papers, we looked to a law firm to manage this matter for us. Amended Drawings were filed and the Patent issued in due course.
