Corrections to patent application publications due to USPTO error
As set forth in 37 CFR 1.221(b), the Office will grant a request for correction to a published patent application only where the Office has made a material mistake which is apparent from Office records.
Note: Only errors that are material will be corrected.
What is the criteria for a material mistake?
A material mistake must affect the public's ability to:
- appreciate the technical disclosure of the patent application publication,
- determine the scope of the patent application publication; or
- determine the scope of the provisional rights that an applicant might seek to enforce upon issuance of a patent.
Examples of errors that may be considered to be material errors :
- missing claims
- missing pages of the specification
- missing pages of drawings
Examples of errors that are not material errors :
- missing assignment information
- missing section headings
- minor typographical errors

**Time limitation ** The request for a corrected patent application must be filed within two months from the date of the patent application publication. Extensions of time are not permitted.
