Patent Term, Family, and Expiration Analysis for US 12308087

Continuation and Family Data

U.S. Patent 12,308,087 is part of a large family of patents stemming from a long chain of continuation applications. The "RELATED APPLICATION" section of the patent's description and public records detail this history.

The application for this patent (Ser. No. 17/694,649, filed March 14, 2022) is a continuation of at least seven earlier non-provisional applications. The chain of priority, which determines the patent's term, is as follows:

• U.S. Provisional Application No. 61/409,893, filed on November 3, 2010.
• The earliest non-provisional application in the chain is Ser. No. 13/288,850, filed on November 3, 2011, which resulted in U.S. Patent 8,787,060.
• This was followed by a series of continuation applications leading to the '087 patent:
  • Ser. No. 14/337,168 (now Pat. No. 9,318,160)
  • Ser. No. 15/095,288 (now Pat. No. 9,659,601)
  • Ser. No. 15/602,099 (now Pat. No. 10,290,328)
  • Ser. No. 16/412,308 (now Pat. No. 10,902,886)
  • Ser. No. 17/157,903 (Abandoned)
  • Ser. No. 17/694,649 (Resulting in the patent in question, US 12,308,087)

Divisional Applications

Based on the provided patent text and public records, there is no indication that any divisional applications have been filed from this patent or its parent applications. The family relationship is described exclusively through continuation applications.

Patent Term Adjustment (PTA) and Extension (PTE)

• Patent Term Adjustment (PTA): A detailed review of the file history via the USPTO's Patent Center is required to determine the exact number of PTA days, if any, awarded to this patent. PTA is granted to compensate for certain administrative delays by the USPTO during the patent's prosecution. However, the "Anticipated expiration" date listed in the Google Patents record corresponds exactly to a 20-year term from the earliest non-provisional filing date, suggesting that any PTA awarded may be zero or has not been factored into that specific data point.
• Patent Term Extension (PTE): There is no indication that this patent is eligible for or has been granted a PTE. PTE is typically associated with delays in regulatory review (e.g., by the FDA for pharmaceutical products) and does not apply to this technology area.

Projected Expiration Date

The term for a U.S. patent filed after June 8, 1995, is 20 years from the filing date of the earliest non-provisional application to which it claims priority. Provisional application filing dates are not used in this calculation.

1. Earliest Non-Provisional Filing Date: The earliest non-provisional application in this patent's family is Ser. No. 13/288,850, which was filed on November 3, 2011.
2. Base Expiration Date: Adding 20 years to this date yields a base expiration date of November 3, 2031. This date aligns with the "Anticipated expiration" listed in public patent data.
3. Terminal Disclaimer: The patent is noted to be subject to a terminal disclaimer. This means its term cannot extend beyond the expiration date of an earlier patent in the family to which it is linked. In this case, since the '087 patent is at the end of a long continuation chain, the terminal disclaimer effectively ensures it does not extend beyond the statutory term calculated from the earliest parent application.

Therefore, assuming no positive or negative patent term adjustments, the projected expiration date for U.S. Patent 12,308,087 is November 3, 2031.
