Extensions

To provide a comprehensive analysis of patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date for US patent 12044901, I will access the USPTO patent information.

The USPTO does not directly calculate expiration dates for patents but provides resources and tools for this purpose, emphasizing that various factors must be considered, including filing dates, grant dates, benefit claims, PTA/PTE, and terminal disclaimers.

Patent Term Adjustments (PTA)
Patent Term Adjustment (PTA) extends a utility patent's term beyond the standard 20 years to compensate for delays in the USPTO examination process. Accurate PTA input is essential for a correct expiration calculation.

Patent Term Extensions (PTE)
Patent Term Extension (PTE) is available under the Hatch-Waxman Act for patents on certain products (e.g., human drugs, medical devices, food additives) that require regulatory approval, to restore some of the patent term lost during the premarket government approval process. PTE is limited to a maximum of five years, and the total patent life with a PTE cannot exceed 14 years from the date of FDA approval.

Continuation Applications, Divisional Applications, and Related Family Members
Patent expiration calculations involve analyzing the earliest effective filing date and continuity claims under 35 U.S.C. §§ 120, 121, or 365(c). The Google Patents page for US12044901B2 lists several "external-priority" documents, which are earlier applications from which this patent claims priority. These indicate a family of related patent applications:

• US11/580,222 (Priority claimed from 2006-10-11)
• US11/891,411 (Priority claimed from 2007-08-09)
• US12/462,286 (Priority claimed from 2009-07-31)
• US12/806,312 (Priority claimed from 2010-08-10)
• US13/085,402 (Priority claimed from 2011-04-12)

These are likely part of a continuation or divisional application chain, as they represent a series of filings that claim priority back to an earlier application. The priority date of US12044901 is listed as 2005-10-11, which would correspond to the earliest effective filing date among these family members for the purpose of calculating the base 20-year patent term.

Projected Expiration Date
The standard term for a utility patent is 20 years from the earliest effective filing date. For US12044901, the earliest priority date is 2005-10-11.

Therefore, the anticipated expiration date, before considering any PTA or terminal disclaimers, would be 20 years from this priority date.

• Earliest Priority Date: 2005-10-11
• Base Expiration Date (20 years from priority date): 2025-10-11

The Google Patents page explicitly lists "Anticipated expiration: 2026-10-11". This suggests that there might be a Patent Term Adjustment (PTA) of approximately one year, or a different interpretation of the priority date for calculation. Without access to the official USPTO patent prosecution history, including any PTA grants or terminal disclaimers, it is not possible to precisely confirm the exact calculation leading to the 2026-10-11 expiration date. However, the Google Patents information provides a strong indicator for this projected date.

Summary for US12044901:

• Patent Term Adjustments (PTA): The Google Patents page indicates an "Anticipated expiration" of 2026-10-11, which is one year after the standard 20-year term from the earliest priority date (2005-10-11). This suggests a PTA of approximately one year, though the specific details of its calculation are not publicly available in the provided text.
• Patent Term Extensions (PTE): There is no information in the provided patent text or search results to indicate that US12044901 has received a Patent Term Extension under 35 U.S.C. § 156. Such extensions are typically for patents related to products requiring regulatory approval (e.g., pharmaceuticals, medical devices).
• Continuation Applications/Divisional Applications: The patent claims priority from several earlier applications: US11/580,222, US11/891,411, US12/462,286, US12/806,312, and US13/085,402. These represent the continuation/divisional family members, tracing back to the earliest priority date of 2005-10-11.
• Related Family Members: As noted above, the related family members are the priority applications: US11/580,222, US11/891,411, US12/462,286, US12/806,312, and US13/085,402.
• Projected Expiration Date: The Google Patents page lists the "Anticipated expiration" as 2026-10-11.
