Extensions

For US patent 8524300, here's a breakdown of its term adjustments, family members, and projected expiration:

Patent Term Adjustment (PTA) and Patent Term Extension (PTE):
Based on the provided information, the patent document for US8524300 does not explicitly detail any Patent Term Adjustment (PTA) or Patent Term Extension (PTE) calculations. PTA is granted to compensate for delays by the USPTO during patent prosecution, while PTE is available for patents on certain products (like human drugs, medical devices, food additives) to restore patent term lost during premarket regulatory review. Since US8524300 relates to a "covered retracted confectionery," it is highly unlikely to be eligible for PTE, which is typically reserved for regulated products requiring FDA approval. To determine any specific PTA granted, one would typically need to review the patent's prosecution history (file wrapper) available through USPTO Patent Center.

Continuation and Divisional Applications:
The patent document lists US13/463,762 as the application number for US8524300. It also shows a "Priority to US13/463,762" and a "Priority to CN2013200258993U." The US application number US13/463,762 is the filing for US8524300 itself, not a parent or child application in a continuation or divisional chain. The Chinese application CN2013200258993U (which published as CN203173166U) is a priority application, indicating that US8524300 claims priority to it, or it claims priority to US13/463,762. There is no information within the provided patent text to suggest that US8524300 is a continuation, divisional, or continuation-in-part of an earlier US application.

Related Family Members:

• US Priority Application: US13/463,762 (This is the application that matured into US8524300B1).
• Foreign Priority Application: CN2013200258993U (Published as CN203173166U, titled "Retractable candy cover"). This Chinese patent appears to be a related family member, claiming priority from or providing priority to the US application.

Projected Expiration Date:
The patent document explicitly states the "Anticipated expiration" date for US8524300 as 2032-05-03. This date is typically calculated as 20 years from the earliest effective filing date, plus any Patent Term Adjustment (PTA). The filing date for US13/463,762 (which resulted in US8524300) was 2012-05-03. Therefore, the 20-year term from the filing date would be 2032-05-03, suggesting that any PTA applied would have been minimal or accounted for in this listed expiration date.
