WARNING:

Petitioner/applicant is cautioned to avoid submitting personal information in documents filed in a patent application that may contribute to
identity theft. Personal information, such as social security numbers, bank account numbers, or credit card numbers (other than a check or
credit card authorization form (PTO-2038) submitted for payment purposes), is never required by the USPTO to support a petition or an
application. If this type of personal information is included in documents submitted to the USPTO, petitioner/applicant should consider
redacting such personal information from the documents before submitting them to the USPTO. Petitioner/applicant is advised that the
record of a patent application is available to the public after publication of the application (unless a non-publication request in compliance
with 37 CFR 1.213(a) is made in the application or issuance of a patent. Furthermore, the record from an abandoned application may also
be available to the public if the application is referenced in a published application or an issued patent (see 37 CFR 1.14). Checks and credit
card authorization forms (PTO-2038) submitted for payment purposes are not retained in the application file and therefore are not publicly
available.
10. STATEMENT
The delay in payment of the maintenance fee for this patent was unintentional.
Petitioner is reminded that a delay resulting from a deliberately chosen course of action or a change in circumstance is not an unintentional
delay.
Petitioner is further reminded that a person seeking reinstatement of an expired patent should not make a statement that the delay in
payment of the maintenance fee was unintentional unless the entire delay was unintentional, including the period from discovery that the
maintenance fee was not timely paid until payment of the maintenance fee. For example, a statement that the delay in payment of the
maintenance fee was unintentional would not be proper when the patentee becomes aware of an unintentional failure to timely pay the
maintenance fee and then intentionally delays filing a petition for reinstatement of the patent under 37 CFR 1.378. See MPEP 2590.
NOTE: Where the petition under 37 CFR 1.378 is filed more than two years after the date the patent expired for nonpayment of the
maintenance fee, the United States Patent and Trademark Office requires an additional explanation of the circumstances surrounding the
delay that establishes the entire delay was unintentional. This requirement is in addition to the requirement to provide a statement that the
entire delay was unintentional. See Clarification of the Practice for Requiring Additional Information in Petitions Filed in Patent Applications
and Patents Based on Unintentional Delay, 85 FR 12222 (March 2, 2020). See MPEP 711.03(c)(II)(C)-(F) for additional guidance on the
information required to establish that the entire delay was unintentional.
Because this petition under 37 CFR 1.378 is being filed more than two years after the date the patent expired for nonpayment of the
maintenance fee, additional explanation of the circumstances surrounding the delay that establishes the entire delay was
unintentional is enclosed herewith.
