Extensions

The provided patent text already contains a significant amount of the requested information, specifically regarding the priority chain and the adjusted expiration date. I will consolidate this information and use the search results to confirm or find additional details, especially for PTA/PTE and to explicitly differentiate between continuation and divisional applications if possible.

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

• The nature of the patent (stroller attachments) makes it unlikely to qualify for PTE under the Hatch-Waxman Act, which is primarily for pharmaceutical products, medical devices, and food/color additives requiring regulatory approval. There is no indication in the patent text or search results that this patent covers such a product.
• PTA, on the other hand, is generally applicable to utility and plant patent applications to compensate for delays caused by the USPTO during prosecution. The Google Patents page lists an "Adjusted expiration" date of 2029-12-04, which suggests that some patent term adjustment was applied, as a patent filed on 2008-12-04 (priority date of the earliest application in the chain) would normally expire 20 years from the earliest non-provisional filing date, or 20 years from the filing date of the application if it does not claim priority to an earlier application. Given the filing date of US17/876,492 is 2022-07-28, and the original priority date (US12/631,375) is 2009-12-04 (which claims benefit of 61/119,920 filed Dec 4, 2008), the adjusted expiration date likely accounts for delays. Without access to the specific prosecution history, the exact calculation of PTA is not readily available through general search or the provided text.

Continuation Applications, Divisional Applications, and Related Family Members:

The provided patent text clearly outlines a complex priority chain, indicating numerous continuation applications. The current patent, US11577771B2, is a continuation of several earlier applications. No specific "divisional applications" are explicitly called out in the provided text, though continuation applications are a type of related family member.

• Continuation Applications (in priority order, leading to US11577771B2):

  • U.S. patent application Ser. No. 16/903,292, filed Jun. 16, 2020.
  • U.S. patent application Ser. No. 15/912,901, filed Mar. 6, 2018 (issued as U.S. Pat. No. 10,730,543).

• Other Versions / Related Family Members (from Google Patents info):

  • US20220371641A1 (publication of the present application).

• Divisional Applications: The provided text does not explicitly mention any divisional applications. Divisional applications arise from an earlier application that contained claims to more than one invention.

Projected Expiration Date:

• The Google Patents page for US11577771B2 states a "Legal status (The legal status is an assumption and is not a legal conclusion...): Active, expires 2029-12-04". This is an adjusted expiration date.

Since most of the information is directly available in the provided text, and the nature of PTA/PTE is general knowledge based on the searches, I can now construct the response. I do not have direct access to USPTO databases to check the specific PTA statement from the examiner, so I will rely on the "Adjusted expiration" date provided on the Google Patents page as the result of any such adjustment.US Patent 11577771, titled "Removable seat attachment for a stroller," has the following details regarding its term and family:

Patent Term Adjustments (PTA):
While the exact calculation of Patent Term Adjustment (PTA) for US 11577771 is not directly available without access to its specific prosecution history in the USPTO's Patent Center, the Google Patents page indicates an "Adjusted expiration" date of 2029-12-04. This adjustment suggests that PTA was applied to compensate for delays caused by the USPTO during the patent's prosecution, as is standard for utility and plant patent applications filed on or after May 29, 2000.

Patent Term Extensions (PTE):
There is no indication that US 11577771 has received or is eligible for Patent Term Extension (PTE). PTE typically applies to patents covering certain products (e.g., pharmaceuticals, medical devices, food additives) that undergo lengthy regulatory review periods before commercial marketing. The subject matter of this patent, related to stroller attachments, does not fall into these categories.

Continuation Applications:
US 11577771 is a continuation application derived from a long chain of previous applications. The priority chain leading to this patent is as follows:
