Extensions

To provide the most accurate information regarding US Patent 12004262, a direct search on the USPTO's Patent Public Search database is necessary. While some general information about the patent is available in the provided text, specific details about patent term adjustments, extensions, and the full family tree are best obtained from the official USPTO records.

Based on the information available:

• Patent Number: US12004262B2 (granted on 2024-06-04)

Patent Term Adjustment (PTA) and Patent Term Extension (PTE):
The provided text does not explicitly state any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) for US12004262B2.

• PTA is granted to compensate for administrative delays by the USPTO during patent prosecution for utility or plant patent applications.
• PTE is awarded to compensate for delays in obtaining regulatory approval for patented products, such as drugs.

To confirm any PTA or PTE, a direct check of the patent's prosecution history on the USPTO website would be required, as the USPTO does not calculate expiration dates for patents but provides tools to estimate them.

Continuation Applications, Divisional Applications, and Related Family Members:

• Application Number: US17/670,419
• Priority Date: 2017-04-14
• Priority Claimed From: KR1020170048762A
• Other versions/Family Members: US20220167460A1

The patent claims priority to US17/670,419 and KR1020170048762A. US20220167460A1 is an earlier publication of this patent family.

A continuation application pursues additional claims to an invention disclosed in an earlier, still-pending "parent" application, using the same specification and claiming the same priority date.
A divisional application also claims priority to a parent application but covers a distinct invention "carved out" due to a restriction requirement from the examiner, and generally has the same specification but different claims.
A continuation-in-part (CIP) application includes substantially the same specification as the parent but adds new subject matter, resulting in a split priority date where new matter claims are only entitled to the CIP's filing date.

The provided data does not specify if US12004262B2 is a continuation, divisional, or continuation-in-part of US17/670,419 or if there are other pending continuation or divisional applications.

Projected Expiration Date:
The anticipated expiration date for US12004262B2 is 2038-04-16.

For utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the earliest filing date of the application, or of an earlier application to which it claims priority. Since the priority date is 2017-04-14, a standard 20-year term would typically end around April 14, 2037. However, the provided expiration date of 2038-04-16 indicates that there has been an adjustment, likely due to Patent Term Adjustment (PTA), which extends the patent term to compensate for USPTO delays.
