Extensions

The USPTO does not calculate patent expiration dates directly, but provides tools and guidance for their estimation.

Here's an analysis for US patent 12268475 based on the provided information:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can extend a patent's term to compensate for delays by the USPTO during patent prosecution. These delays include failing to issue an office action within 14 months, failing to respond to a reply or appeal within four months, or failing to issue the patent within 36 months of the filing date. Applicant delays can reduce any granted PTA.

The provided patent text for US12268475 does not explicitly state whether any Patent Term Adjustments were granted. To determine the precise PTA, one would typically need to review the patent's prosecution history (e.g., in Patent Center on the USPTO website) and refer to the Certificate of Adjustment.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available for patents on certain human drugs, medical devices, food additives, color additives, animal drugs, and veterinary biological products. This extension aims to restore some of the patent term lost due to the time spent awaiting premarket government approval from a regulatory agency like the FDA. 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.

US patent 12268475 is titled "Wearable device for differential measurement on pulse rate and blood flow," which falls under the category of medical devices. Therefore, it may be eligible for a Patent Term Extension if it meets the criteria under 35 U.S.C. § 156. However, the provided text does not indicate whether an application for PTE has been filed or granted for this specific patent.

Continuation and Divisional Applications

• Continuation Applications: A continuation application is a second application for the same invention claimed in a prior non-provisional application and filed before the patenting or abandonment of the prior application.
• Divisional Applications: A divisional application is a later application for an independent and distinct invention carved out of an earlier, broader application.

The information provided for US12268475 does not explicitly mention any continuation or divisional applications directly associated with this patent number.

Related Family Members

The Google Patents listing indicates that US12268475B2 claims priority from several earlier applications. These priority claims establish family relationships:

• PCT/US2013/075736: Priority claimed from 2013-12-17
  • Related patent: WO2014105521A1
• PCT/US2013/075700: Priority claimed from 2013-12-17
  • Related patent: WO2014105520A1
• US14/108,986: Priority claimed from 2013-12-17
  • Related patent: US9164032B2
• US14/109,007: Priority claimed from 2013-12-17
  • Related patent: US9993159B2
• US15/711,907: Priority claimed from 2017-09-21
  • Related patent: US9897584B2
• US17/514,778: Priority claimed from 2021-10-29
  • Related patent: US11564577B2

Additionally, US12268475B2 itself has an "Other version" listed:

• US20250049326A1

The priority date of US12268475B2 is December 31, 2012, based on the earliest cited priority date in the Google Patents listing. The filing date of the specific application that led to US12268475B2 is October 25, 2024.

Projected Expiration Date

For utility patents filed on or after June 8, 1995, the patent term generally ends 20 years from the date on which the application for the patent was filed, or if the application claims priority to an earlier application under 35 U.S.C. §§ 120, 121, 365(c), or 386(c), then 20 years from the filing date of the earliest such application. This term can be adjusted by PTA or extended by PTE.

Given:

• Earliest Priority Date: December 31, 2012
• Filing Date of US12268475: October 25, 2024
• Issue Date: April 8, 2025

The patent term for US12268475 would typically be 20 years from its earliest priority date.

Therefore, the anticipated expiration date, without considering any PTA or PTE, would be December 31, 2032. The Google Patents record also lists an "Anticipated expiration" date of 2033-12-17. This discrepancy suggests that a Patent Term Adjustment (PTA) of approximately one year was granted. The USPTO does not calculate expiration dates for patents, but provides a calculator to help estimate them.

To confirm the exact expiration date and any PTA, one would need to access the official USPTO Patent Center for US12268475 and review the patent's front page and Certificate of Adjustment. Without this information, the Google Patents "Anticipated expiration" date of 2033-12-17 provides the best available estimate.
