MPEP 130-Examination of Secrecy Order Cases (1)

As explained in MPEP 130, when a patent application under a Secrecy Order is in condition for allowance, “a notice of allowability (Form D-10) is issued, thus closing the prosecution.” See 37 CFR 5.3(c).

After the notice of allowability is issued, any amendments received are not entered or responded to until the Secrecy Order is rescinded. Once the Secrecy Order is rescinded, amendments will be entered if they are free from objections, otherwise they will be denied entry.

MPEP 200 - Types and Status of Application; Benefit and Priority (1)

Amendments can be made when filing a Continued Prosecution Application (CPA), but there are important restrictions and considerations:

  • Any changes must be made as an amendment to the prior application as it existed before filing the CPA
  • No new matter can be introduced in a CPA
  • Preliminary amendments filed with a CPA are generally entered, but could be denied entry if they unduly interfere with examination
  • New specifications filed with a CPA request are treated as substitute specifications and must comply with 37 CFR 1.125

The MPEP states: Any new change must be made in the form of an amendment to the prior application as it existed prior to the filing of an application under this paragraph. No amendment in an application under this paragraph (a continued prosecution application) may introduce new matter or matter that would have been new matter in the prior application.

Regarding preliminary amendments, the MPEP advises: Applicants are also encouraged to file all preliminary amendments at the time of filing a CPA because the entry of any preliminary amendment filed after the filing date of the CPA could be denied under 37 CFR 1.115 if the preliminary amendment unduly interferes with the preparation of a first Office action.

If more time is needed to prepare amendments, applicants can request a three-month suspension of action under 37 CFR 1.103(b) at the time of filing the CPA.

MPEP 200 - Types and Status of Application; Benefit and Priority Claims (2)

According to MPEP 203.03, a nonprovisional patent application is considered “amended” after it has been initially acted on by the examiner, and the applicant has filed a reply to the examiner’s action. The applicant’s reply may include:

  • An election
  • A traverse of the examiner’s action
  • An amendment to the application

To amend your application to include inadvertently omitted material under 37 CFR 1.57(b), you must:

  1. File an amendment to include the omitted material within the time period set by the USPTO
  2. Ensure the amendment is filed before the close of prosecution or abandonment of the application
  3. Supply a copy of the prior-filed application (unless it’s a US application filed under 35 U.S.C. 111)
  4. Provide an English translation if the prior-filed application is in a foreign language
  5. Identify where the omitted material can be found in the prior-filed application

The MPEP states: “The application must be amended to include the inadvertently omitted portion of the specification or drawing(s) within any time period set by the Office, but in no case later than the close of prosecution as defined by 37 CFR 1.114(b), or abandonment of the application, whichever occurs earlier.”

MPEP 201 - Types of Applications (1)

Amendments can be made when filing a Continued Prosecution Application (CPA), but there are important restrictions and considerations:

  • Any changes must be made as an amendment to the prior application as it existed before filing the CPA
  • No new matter can be introduced in a CPA
  • Preliminary amendments filed with a CPA are generally entered, but could be denied entry if they unduly interfere with examination
  • New specifications filed with a CPA request are treated as substitute specifications and must comply with 37 CFR 1.125

MPEP 203 - Status of Applications (1)

According to MPEP 203.03, a nonprovisional patent application is considered “amended” after it has been initially acted on by the examiner, and the applicant has filed a reply to the examiner’s action. The applicant’s reply may include:

  • An election
  • A traverse of the examiner’s action
  • An amendment to the application

MPEP 217-Incorporation by Reference Under 37 CFR 1.57(b) (1)

To amend your application to include inadvertently omitted material under 37 CFR 1.57(b), you must:

  1. File an amendment to include the omitted material within the time period set by the USPTO
  2. Ensure the amendment is filed before the close of prosecution or abandonment of the application
  3. Supply a copy of the prior-filed application (unless it’s a US application filed under 35 U.S.C. 111)
  4. Provide an English translation if the prior-filed application is in a foreign language
  5. Identify where the omitted material can be found in the prior-filed application

The MPEP states: “The application must be amended to include the inadvertently omitted portion of the specification or drawing(s) within any time period set by the Office, but in no case later than the close of prosecution as defined by 37 CFR 1.114(b), or abandonment of the application, whichever occurs earlier.”

MPEP 400 - Representative of Applicant or Owner (2)

Amendments and other papers filed in a patent application must be signed by specific individuals as outlined in 37 CFR 1.33(b):

  1. A patent practitioner of record
  2. A patent practitioner not of record who acts in a representative capacity under the provisions of 37 CFR 1.34
  3. The applicant (37 CFR 1.42)

It’s important to note that for juristic entities (e.g., corporations), 37 CFR 1.33(b)(3) specifies:

“Unless otherwise specified, all papers submitted on behalf of a juristic entity must be signed by a patent practitioner.”

This requirement ensures that juristic entities are properly represented in patent proceedings.

When a power of attorney is revoked, it’s important to understand its impact on pending amendments in a patent application. According to MPEP 402.05:

Any amendments made in an application after the filing date of the application will not be effective to revoke a power of attorney.

This means that if an applicant submits an amendment to revoke a power of attorney after the application’s filing date, that amendment will not be effective in revoking the power of attorney. To properly revoke a power of attorney, the applicant must follow the specific procedures outlined in the MPEP, such as submitting a separate revocation document or a new power of attorney.

‘New matter’ refers to any subject matter that is added to a patent application after its filing date, which was not present in the original specification, claims, or drawings. The MPEP states: Matter not present on the filing date of the application in the specification, claims, or drawings that is added after the application filing is usually new matter. (MPEP 608.04(a))

New matter can include:

  • Addition of wholly unsupported subject matter
  • Adding specific percentages or compounds after a broader original disclosure
  • Omission of a step from a method

It’s important to note that new matter is not allowed in patent applications, as per 35 U.S.C. 132(a), which states: No amendment shall introduce new matter into the disclosure of the invention.

Can drawings be amended after the application filing date without introducing new matter?

Amending drawings after the application filing date without introducing new matter is possible, but it requires careful consideration. According to MPEP 608.04(a):

‘An amendment to the drawings, however, which adds a feature not disclosed in the original drawings or specification involves new matter.’

This means that while you can make amendments to drawings, any new features or elements not disclosed in the original application will be considered new matter. Acceptable amendments typically include:

  • Correcting minor errors or inconsistencies
  • Improving clarity or resolution of existing features
  • Adding reference numbers or labels to existing elements

It’s crucial to ensure that any changes to drawings are fully supported by the original disclosure. If significant changes are needed that would introduce new matter, filing a continuation-in-part application may be necessary.

Generally, amendments to a provisional application are not permitted after the filing date, except for those required to comply with applicable regulations. The MPEP clearly states:

Amendments, other than those required to make the provisional application comply with applicable regulations, are not permitted after the filing date of the provisional application. (MPEP 601.01(b))

This restriction helps maintain the integrity of the provisional application as a snapshot of the invention at the time of filing.

To learn more:

No, supplemental oaths or declarations filed after allowance are not considered amendments under 37 CFR 1.312. The MPEP explicitly states:

“They should not be filed or considered as amendments under 37 CFR 1.312, since they make no change in the wording of the papers on file.”

This means that supplemental oaths or declarations do not alter the content of the application and are treated differently from post-allowance amendments.
