Extensions

For US Patent 11,620,634, here is a detailed breakdown of its prosecution history and projected expiration:

Patent Term Adjustment (PTA)

Patent Term Adjustment (PTA) is granted to compensate for delays caused by the USPTO during the prosecution of a patent application. This adds additional time to the patent's term beyond the standard 20 years from the earliest filing date. The USPTO automatically determines the PTA and provides a notice of determination by the patent's issue date.

To determine the exact PTA for US11620634, access to the patent's Public PAIR (Patent Application Information Retrieval) record would be required. This record provides specific details on USPTO delays (e.g., failure to issue an office action within 14 months, failure to respond to an amendment within 4 months, or failure to issue a patent within 36 months of filing) and any applicant-caused delays that would reduce PTA.

Patent Term Extension (PTE)

Patent Term Extension (PTE) is a separate mechanism that extends a patent's term to compensate for delays incurred during the regulatory review process of a product by agencies like the FDA or Department of Agriculture. This applies to patents claiming drug products, medical devices, food additives, or color additives. The maximum length of a PTE is five years, and it cannot extend the total post-approval patent life beyond 14 years from the date of marketing approval.

Given that US Patent 11,620,634 pertains to a "Multi-function smart tokenizing electronic payment device," it is highly unlikely to be eligible for Patent Term Extension under 35 U.S.C. § 156, as its subject matter does not fall within the categories of products requiring regulatory approval (e.g., drugs, medical devices, food additives).

Continuation Applications

US Patent 11,620,634 is a continuation application itself. It explicitly states in its "Related Applications" section:
"This is a Continuation application of commonly-owned U.S. patent application Ser. No. 17/075,637, now U.S. Pat. No. 11,176,538, filed Oct. 2, 2020, which in turn was in turn a Continuation application of commonly-owned U.S. patent application Ser. No. 16/459,150, now U.S. Pat. No. 10,810,579, filed Jul. 1, 2019, which in turn was a Continuation application of commonly-owned U.S. patent application Ser. No. 15/701,261, now U.S. Pat. No. 10,339,520, filed Sep. 11, 2017, which in turn was a Continuation application U.S. patent application Ser. No. 14/981,757, filed Dec. 28, 2015, now U.S. Pat. No. 9,760,884, which in turn was a continuation of U.S. patent application Ser. No. 14/680,979, filed Apr. 7, 2015, now U.S. Pat. No. 9,224,083, which in turn was a Division of U.S. patent application Ser. No. 14/217,261, filed Mar. 17, 2014, now U.S. Pat. No. 9,022,286, which in turn claims priority from Provisional Application 61/794,891, filed Mar. 15, 2013, each of which are hereby incorporated herein in their entirety by reference."

This chain of applications indicates that US11620634 is part of an extensive patent family stemming from a provisional application.

Divisional Applications

The "Related Applications" section states that U.S. patent application Ser. No. 14/680,979 (now U.S. Pat. No. 9,224,083) "was a Division of U.S. patent application Ser. No. 14/217,261, filed Mar. 17, 2014, now U.S. Pat. No. 9,022,286". This explicitly identifies a divisional application within the patent family.

Related Family Members

Based on the "Related Applications" section, the following are identified as related family members, sharing priority back to the initial provisional application:

• U.S. Provisional Application No. 61/794,891, filed Mar. 15, 2013 (priority date)
• U.S. patent application Ser. No. 14/217,261, filed Mar. 17, 2014, now U.S. Pat. No. 9,022,286
• U.S. patent application Ser. No. 14/680,979, filed Apr. 7, 2015, now U.S. Pat. No. 9,224,083
• U.S. patent application Ser. No. 14/981,757, filed Dec. 28, 2015, now U.S. Pat. No. 9,760,884
• U.S. patent application Ser. No. 15/701,261, filed Sep. 11, 2017, now U.S. Pat. No. 10,339,520
• U.S. patent application Ser. No. 16/459,150, filed Jul. 1, 2019, now U.S. Pat. No. 10,810,579
• U.S. patent application Ser. No. 17/075,637, filed Oct. 2, 2020, now U.S. Pat. No. 11,176,538
• U.S. patent application Ser. No. 17/528,073, filed Nov. 16, 2021, which resulted in U.S. Pat. No. 11,620,634
• US20220207517A1 (other version, likely the publication of US17/528,073)

Additionally, the Google Patents information for US11620634 lists the following priorities:

• Priority to US17/528,073 (2021-11-16)
• Priority to US18/125,624 (2023-03-23)
• Priority to US19/429,187 (2025-12-22)

These indicate further continuation applications filed after the issue date of US11620634, extending the family tree.

Projected Expiration Date

The statutory term for a U.S. utility patent like 11,620,634 is generally 20 years from its earliest effective filing date. Since US11620634 claims priority from Provisional Application 61/794,891, filed on March 15, 2013, this is the earliest effective filing date for term calculation.

Therefore, without considering any Patent Term Adjustment (PTA) or Patent Term Extension (PTE), the base expiration date would be March 15, 2033.

However, the Google Patents entry explicitly states an "Anticipated expiration" date of 2034-03-17. This indicates that a Patent Term Adjustment (PTA) has been applied. PTA is added to the 20-year term to compensate for USPTO delays during prosecution. The difference between the base expiration date (March 15, 2033) and the anticipated expiration date (March 17, 2034) is approximately one year and two days. This adjustment would have been calculated by the USPTO and typically provided at the time of patent issuance.

Projected Expiration Date: March 17, 2034.
