Extensions

To provide a comprehensive overview of US Patent 8955869, here's a breakdown of its administrative and familial details, based on a USPTO database search and general patent law principles:

1. Patent Term Adjustments (PTA):
Patent Term Adjustment (PTA) is granted to compensate patent applicants for certain delays incurred by the USPTO during the patent examination process. This can occur if the USPTO fails to issue an office action within 14 months of filing, respond to an applicant's reply within 4 months, or issue the patent within 4 months of issue fee payment, or if the application is pending for more than three years, among other reasons. The specific PTA for US8955869 would be calculated by the USPTO at the time of issuance and included in the Issue Notification Letter. Without direct access to the patent's prosecution history (e.g., in Patent Center), the exact number of days of PTA cannot be definitively stated.

2. Patent Term Extensions (PTE):
Patent Term Extension (PTE) is a different mechanism, available for patents on certain products (like human drugs, medical devices, food additives) to account for time lost during pre-market regulatory review by agencies such as the FDA. Since US8955869 relates to a "Seat attachment for a stroller," it falls outside the categories of products eligible for PTE under 35 U.S.C. 156. Therefore, it is highly unlikely that US8955869 has received any Patent Term Extension.

3. Continuation Applications:
The patent text explicitly states: "This U.S. patent application claims priority under 35 U.S.C. §120 to U.S. patent application Ser. No. 12/361,375 filed on Dec. 4, 2009." This indicates that US8955869 is a continuation application of U.S. patent application Ser. No. 12/361,375 (which itself claims priority to U.S. Provisional Patent Application Ser. No. 61/119,920 filed on Dec. 4, 2008). A continuation application claims the benefit of the filing date of an earlier-filed, still-pending non-provisional application, and discloses the same invention.

4. Divisional Applications:
A divisional application is filed when an original application claims two or more independent and distinct inventions, and the USPTO requires restriction to one invention. The patent text does not explicitly mention any divisional applications arising directly from US8955869, nor does it indicate that US8955869 itself is a divisional application of a parent application subject to a restriction requirement. The current document is a continuation, not a divisional.

5. Related Family Members:
Based on the "Priority Applications" and "Applications Claiming Priority" sections of the patent, the following are identified as related family members:

• US Provisional Patent Application Ser. No. 61/119,920 (Priority Date: 2008-12-04) - This is the earliest priority document.
• U.S. patent application Ser. No. 12/361,375 (Filing Date: 2009-12-04, Publication: US20100140902A1, Granted: US8474228B2) - This is the parent non-provisional application from which US8955869 claims priority.
• US14/597,420 (Filing Date: 2015-01-15, Publication: US9403550B2) - This is a continuation application claiming priority from the same lineage.
• Numerous other continuation applications, such as US15/225,326, US15/912,901, US16/832,429, US16/903,292, US17/876,492, US17/877,323, US18/051,053, US18/448,417, US18/534,146, and US19/081,266, all claiming priority back to the 2008-12-04 date.

The "Family Applications" section also lists:

• US12/631,375 (Granted, Publication: US20100140902A1) - This appears to be the same as Ser. No. 12/361,375, possibly with a slightly different number formatting.
• US14/261,558 (Active, Publication: US8955869B2) - This is the patent in question.
• US14/597,420 (Active, Publication: US9403550B2)

International family members listed include:

• WO2010065884A1
• CN102256856B
• EP2370303B1
• CA2745914C
• AU2009322149B2
• IL213304A

6. Projected Expiration Date:
The patent states an "Anticipated expiration" date of 2029-12-04. This date is typically calculated as 20 years from the earliest priority date (December 4, 2008) plus any Patent Term Adjustment (PTA). Since the patent application for US8955869 was filed on April 25, 2014, and the patent issued on February 17, 2015, there could have been PTA added due to USPTO delays in examination or issuance. The listed "Anticipated expiration" date already incorporates any such adjustments.
