The user is asking for specific details about US patent 11664123 from the USPTO database. I need to find information regarding:

Patent Term Adjustments (PTA)
Patent Term Extensions (PTE)
Continuation applications
Divisional applications
Related family members
Projected expiration date

I will use Google Search to find this information, focusing on USPTO sources or reputable patent databases that provide such details. I will interpret the patent number literally as "US11664123".

Given the current date is 2026-05-18, I will ensure the information is as up-to-date as possible.

Let's break down the search strategy for each item:

PTA/PTE: I'll look for official USPTO records or patent database entries that specifically state PTA or PTE for US11664123. These are typically calculated and noted on the patent's front page or in the prosecution history.
Continuation/Divisional/Related Family Members: I'll look for sections within the patent document itself (e.g., "Cross-Reference to Related Applications") or in patent databases that list related applications (e.g., parent applications, child applications, continuations, divisionals, continuation-in-parts). The Google Patents link provided in the prompt already lists "Other versions" and "Priority to US17/181,423" and "Priority to US18/320,937", which will be useful for this.
Projected Expiration Date: This is typically calculated as 20 years from the earliest non-provisional filing date (or priority date if it's a continuation/divisional and claims benefit), plus any PTA, minus any disclaimers. The Google Patents page provides an "Anticipated expiration" date, which I will use and cross-reference with any other found information.

I already have the Google Patents link (https://patents.google.com/patent/[US11664123](/patent/US11664123)/en) from the previous prompt, which is a good starting point to extract a lot of this information. I will prioritize this authoritative source.

Let's re-examine the provided Google Patents data for US11664123:

Priority date: 2011-08-05
Filing date: 2021-02-22 (for US17/181,423)
Publication date: 2023-05-30
Anticipated expiration: 2039-05-15

Under "Other versions" it lists:

US20210350923A1

Under "Priority to" it lists:

US17/181,423 (Filing date: 2021-02-22)
US18/320,937 (Priority date: 2023-05-19) - This seems to be a later application, possibly a continuation. "patent/US12230394B2/en" is linked here, suggesting US12230394B2 is a child of US18/320,937.

Let's refine the plan:

Extract all family member information from the provided Google Patents data first.
Look for explicit mentions of PTA/PTE within the Google Patents text if available, or confirm with a search.
Confirm the expiration date calculation based on the earliest priority date and PTA/PTE.

From the Google Patents page, I can see:

Application number: US17/181,423
Priority date: 2011-08-05 (This is the earliest priority date mentioned)
Filing date: 2021-02-22 (This is the filing date for US17/181,423, which matured into US11664123)
Publication number: US11664123B2
Publication date: 2023-05-30
Anticipated expiration: 2039-05-15

The patent document itself should have the most authoritative information on related applications and PTA/PTE.

Let's check the Google Patents page for the "Cross-Reference to Related Applications" section in the full patent text to identify continuation, divisional, or continuation-in-part applications.

Looking at the full patent text provided in the prompt:

"CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 17/181,423, filed on Feb. 22, 2021, which is a continuation-in-part of U.S. patent application Ser. No. 13/203,040, filed on Aug. 5, 2011, which is a continuation-in-part of U.S. patent application Ser. No. 12/625,699, filed on Nov. 25, 2009, which claims the benefit of U.S. Provisional Application No. 61/198,126, filed on Nov. 6, 2008, all of which are incorporated herein by reference in their entirety."

This section is crucial!
It states: "This application is a continuation of U.S. patent application Ser. No. 17/181,423, filed on Feb. 22, 2021".
However, the Google Patents info for US11664123 itself states its application number is US17/181,423. This appears to be a contradiction or a typo in the provided full text's "CROSS-REFERENCE TO RELATED APPLICATIONS" section, as a patent is its application.
Let's re-read the "Info" section from the Google Patents page at the very beginning of the provided text:
"Publication number US11664123B2
US17/181,423 (This is listed as a separate number, often indicating the application number for the granted patent.)"

So, US11664123B2 is the granted patent from application US17/181,423.
Therefore, the statement "This application is a continuation of U.S. patent application Ser. No. 17/181,423" is incorrect in the provided text for US11664123B2. It should rather state what US17/181,423 itself is a continuation of.

Let's assume the "CROSS-REFERENCE TO RELATED APPLICATIONS" section within the patent text describes the lineage of US17/181,423, which then became US11664123B2.

Corrected interpretation of "CROSS-REFERENCE TO RELATED APPLICATIONS" (as it applies to the application that led to US11664123B2, which is US17/181,423):

US17/181,423 (filed Feb. 22, 2021, and matured into US11664123B2) is a continuation-in-part of:
- U.S. patent application Ser. No. 13/203,040 (filed Aug. 5, 2011). This explains the "Priority date 2011-08-05" listed on Google Patents.
- Which in turn is a continuation-in-part of:
  - U.S. patent application Ser. No. 12/625,699 (filed Nov. 25, 2009).
  - Which claims the benefit of:
    - U.S. Provisional Application No. 61/198,126 (filed Nov. 6, 2008).

This establishes the priority chain. The earliest priority date is November 6, 2008 (provisional). However, the Google Patents page explicitly lists "Priority date 2011-08-05". This is a discrepancy. I need to clarify which priority date is relevant for expiration calculation. Typically, expiration is 20 years from the earliest non-provisional filing date to which the patent is entitled, plus PTA. The "Priority date" listed on Google Patents usually refers to the earliest effective filing date from which benefits are claimed, for the purposes of prior art analysis.

Let's use the explicit "Priority date 2011-08-05" from the Google Patents "Info" section as the primary date for expiration calculation, as it's the one highlighted. The chain of continuations/CIPs listed in the full text must lead to this 2011-08-05 date as its effective filing date for the claims of US11664123. If 13/203,040 (filed Aug 5, 2011) is a CIP of 12/625,699 (filed Nov 25, 2009), then the claims in 11664123 could be entitled to the 2009 or even 2008 date if they are fully supported by those earlier disclosures. However, for a quick calculation, the earliest cited priority date in the Google Patents summary (2011-08-05) is usually what's used for the 20-year term.

Let's assume the "Anticipated expiration 2039-05-15" from Google Patents already accounts for PTA, and is based on the 2011-08-05 priority date, plus patent term adjustments.

Patent Term Adjustments (PTA) and Patent Term Extensions (PTE):
The Google Patents page itself does not explicitly state the PTA or PTE calculations, only the anticipated expiration. I need to search for this specifically.

- U.S. patent application Ser. No. 12/625,699, filed on Nov. 25, 2009
- U.S. Provisional Application No. 61/198,126, filed on Nov. 6, 2008
Other versions (publications): US20210350923A1 (this is the publication of application 17/181,423)
Priority to US18/320,937: "Priority to US18/320,937 (Priority date: 2023-05-19) patent/US12230394B2/en" - This suggests US11664123 is a parent for US18/320,937 which eventually became US12230394B2. So this is a child application, not a parent.

Let's re-evaluate the "CROSS-REFERENCE TO RELATED APPLICATIONS" in the patent text and clarify the application that became US11664123.
The patent number is US11664123B2.
The application number is US17/181,423 (as stated on the Google Patents info page).

So, the "CROSS-REFERENCE TO RELATED APPLICATIONS" section within US11664123B2 is describing the lineage of US17/181,423.
Therefore:

US17/181,423 (filed 2021-02-22) is a continuation-in-part of US13/203,040 (filed 2011-08-05).
US13/203,040 (filed 2011-08-05) is a continuation-in-part of US12/625,699 (filed 2009-11-25).
US12/625,699 (filed 2009-11-25) claims benefit of US Provisional Application No. 61/198,126 (filed 2008-11-06).

This confirms the chain of priority. The earliest effective filing date to which claims in US11664123 could be entitled, depending on the subject matter, dates back to the provisional application filed on November 6, 2008. However, the Google Patents summary for US11664123 explicitly lists the "Priority date" as 2011-08-05. This means that for at least the claims of US11664123, the earliest subject matter support for patentability purposes is considered to be from the application filed on that date (US13/203,040). The 20-year patent term is generally calculated from the earliest non-provisional filing date to which the patent claims benefit. Here, that would be 2011-08-05 (application 13/203,040), not the 2008 provisional or 2009 non-provisional, implying the claims of 116641423 are only supported by the 2011 application.

Let's confirm the expiration date. 20 years from 2011-08-05 is 2031-08-05. The "Anticipated expiration 2039-05-15" (from Google Patents) is significantly later than this, suggesting a substantial amount of Patent Term Adjustment (PTA) has been granted.

I will conduct targeted searches for PTA/PTE information, as Google Patents typically doesn't detail the breakdown of these adjustments.

Google search queries to confirm PTA/PTE:

"US11664123 USPTO PTA"
"US11664123 patent term adjustment"
"US11664123 patent term extension"

And to confirm related applications and family members:

"US11664123 family"
"US11664123 continuation divisional"

I will use the Google Patents page as the primary source of truth for its directly listed information.

From the Google Patents page already provided in the prompt:
Publication number: US11664123B2
Application number: US17/181,423
Filing date: 2021-02-22
Priority date: 2011-08-05
Publication date: 2023-05-30
Anticipated expiration: 2039-05-15

Other versions:

US20210350923A1 (This is the application publication of US17/181,423)

Priority to:

US17/181,423 (This is the application itself, which is confusingly listed as a priority. It's the application that granted into US11664123.)
US18/320,937 (Priority: 2023-05-19) which leads to US12230394B2. This means US11664123 is a parent of an application that matured into US12230394B2.

Let's use the explicit "CROSS-REFERENCE TO RELATED APPLICATIONS" from the full patent text to clearly define the family relationships for US11664123.

"This application [US17/181,423 leading to US11664123B2] is a continuation of U.S. patent application Ser. No. 17/181,423, filed on Feb. 22, 2021, which is a continuation-in-part of U.S. patent application Ser. No. 13/203,040, filed on Aug. 5, 2011, which is a continuation-in-part of U.S. patent application Ser. No. 12/625,699, filed on Nov. 25, 2009, which claims the benefit of U.S. Provisional Application No. 61/198,126, filed on Nov. 6, 2008, all of which are incorporated herein by reference in their entirety."

This first part of the sentence: "This application is a continuation of U.S. patent application Ser. No. 17/181,423, filed on Feb. 22, 2021" is a misstatement if "This application" refers to the granted patent US11664123. It should instead say that application 17/181,423 is a continuation of something else. However, the initial Google Patents data says the application number for US11664123 is US17/181,423.

So, the most accurate way to interpret the "CROSS-REFERENCE TO RELATED APPLICATIONS" is that it describes the lineage of the application (US17/181,423) that resulted in the patent (US11664123).

Therefore:

US17/181,423 (the application for US11664123B2) is a continuation-in-part of US13/203,040.
US13/203,040 is a continuation-in-part of US12/625,699.
US12/625,699 claims benefit of US Provisional 61/198,126.

The earliest non-provisional filing date to which the patent is entitled, and from which the 20-year term typically begins, is the filing date of application 13/203,040, which is 2011-08-05.

So, the baseline expiration would be 2031-08-05.
The Google Patents anticipated expiration is 2039-05-15. This implies a PTA of about 7 years and 9 months.
I need to check if there is specific PTA or PTE information.
It's rare for Google Patents to explicitly show PTA/PTE breakdowns, but it does show an "anticipated expiration."
Let's confirm with a quick search if there's any explicit mention of PTA or PTE for US11664123.

If I don't find explicit PTA/PTE figures from external searches, I will rely on the "Anticipated expiration" from Google Patents and deduce that it includes any adjustments.

Regarding "continuation applications, divisional applications, related family members":

Continuation/Continuation-in-Part applications (Parents):
- U.S. patent application Ser. No. 13/203,040, filed on Aug. 5, 2011 (CIP of 12/625,699)
- U.S. patent application Ser. No. 12/625,699, filed on Nov. 25, 2009 (CIP of 61/198,126)
Provisional application (Parent):
- U.S. Provisional Application No. 61/198,126, filed on Nov. 6, 2008
Divisional applications: None explicitly mentioned as "divisional" in the cross-reference section for US11664123's lineage.
Child applications (from Google Patents "Priority to"):
- US18/320,937 (filed 2023-05-19), which matured into US12230394B2. This is a child application for which US11664123 serves as a parent.

Let's execute the search to confirm PTA/PTE.For US patent 11664123, here is a detailed breakdown of its prosecution history and projected expiration:

Patent Term Adjustments (PTA) and Patent Term Extensions (PTE)

The Google Patents record for US11664123 indicates an "Anticipated expiration" date of 2039-05-15. The statutory patent term is generally 20 years from the earliest non-provisional filing date to which the patent is entitled. For US11664123, based on its cross-reference to related applications, the earliest non-provisional filing date providing support for its claims is August 5, 2011 (for application Ser. No. 13/203,040).

A 20-year term from August 5, 2011, would lead to a base expiration date of August 5, 2031. The difference between this base date and the anticipated expiration date of 2039-05-15 suggests that a substantial Patent Term Adjustment (PTA) of approximately 7 years and 9 months has been granted. Specific details of the PTA calculation are typically found in the official USPTO patent issuance documents or the prosecution history, which are not explicitly provided in the current patent text or Google Patents summary beyond the anticipated expiration date. There is no information to suggest any Patent Term Extensions (PTE) have been applied.

Continuation and Divisional Applications

The "CROSS-REFERENCE TO RELATED APPLICATIONS" section within US11664123 details its lineage as follows:

US17/181,423 (filed 2021-02-22), which matured into US11664123B2, is a continuation-in-part of U.S. patent application Ser. No. 13/203,040 (filed 2011-08-05).
U.S. patent application Ser. No. 13/203,040 (filed 2011-08-05) is a continuation-in-part of U.S. patent application Ser. No. 12/625,699 (filed 2009-11-25).
U.S. patent application Ser. No. 12/625,699 (filed 2009-11-25) claims the benefit of U.S. Provisional Application No. 61/198,126 (filed 2008-11-06).

Therefore, the parent applications to US11664123 are:

U.S. patent application Ser. No. 13/203,040, filed on August 5, 2011.
U.S. patent application Ser. No. 12/625,699, filed on November 25, 2009.
U.S. Provisional Application No. 61/198,126, filed on November 6, 2008.

There are no explicit divisional applications mentioned in the cross-reference section for the lineage of US11664123.
