Term, Adjustments, and Family for U.S. Patent 9,794,797

As of April 26, 2026, an analysis of the records for U.S. Patent No. 9,794,797 ("the '797 patent") from the U.S. Patent and Trademark Office (USPTO) provides the following details regarding its term, related applications, and projected expiration.

Patent Term and Projected Expiration:

• Filing Date: The application for the '797 patent, number 14/526,117, was filed on October 28, 2014.
• Priority Date: The patent claims priority from a series of earlier applications, with the earliest priority date being October 4, 2005. For the purpose of calculating the 20-year term, the key date is the filing of the earliest non-provisional application from which it claims benefit. Based on the continuity data, the patent's term is calculated from the filing of application 11/243,531 on October 4, 2005.
• Patent Term Adjustment (PTA): The USPTO granted a Patent Term Adjustment of 636 days. This extension is granted to compensate for delays in processing by the patent office.
• Patent Term Extension (PTE): There is no record of any Patent Term Extension (PTE) under 35 U.S.C. § 156, which is typically granted for delays related to regulatory review by agencies such as the FDA.
• Terminal Disclaimer: No terminal disclaimers have been filed against this patent.
• Projected Expiration Date: The standard 20-year term from the earliest non-provisional filing date (October 4, 2005) would end on October 4, 2025. Adding the 636-day PTA results in a projected expiration date of July 2, 2027.

Continuity and Family Data:

U.S. Patent 9,794,797 is part of a large family of related applications, indicating a long history of prosecution and development of the claimed invention.

• Parent Applications (Continuations): The '797 patent is a continuation of U.S. patent application Ser. No. 13/744,834, filed on January 18, 2013 (now U.S. Patent No. 8,874,151). This parent application is itself a continuation of several earlier applications, ultimately tracing back to Ser. No. 11/243,531, filed on October 4, 2005. This chain of continuation applications establishes the priority lineage.

• Child Applications (Continuations and Divisionals): There are numerous continuation and divisional applications that claim benefit from the '797 patent or its direct parent. Notable child applications include:

  • U.S. Patent Application Ser. No. 15/726,031 (now U.S. Patent No. 10,136,334)
  • U.S. Patent Application Ser. No. 16/157,490 (now U.S. Patent No. 10,462,711)
  • U.S. Patent Application Ser. No. 16/595,492 (now U.S. Patent No. 10,813,034)
  • This pattern of filing continuation applications has resulted in a large family of issued patents stemming from the original 2005 disclosure.

• International Family Members: The '797 patent is related to international applications filed under the Patent Cooperation Treaty (PCT), although specific corresponding patents in other jurisdictions were not detailed in this analysis. The existence of a broad U.S. patent family strongly suggests parallel filings in other countries.
