Extensions

To provide details on patent term adjustments (PTA), patent term extensions (PTE), continuation applications, divisional applications, related family members, and the projected expiration date for US Patent 9,800,633, I need to access its full prosecution history and official USPTO records. While I can confirm the general concepts of these patent terms, I cannot directly browse the USPTO database for specific details on this patent with the provided tools.

Based on the information available:

• Patent Term Adjustment (PTA): Patent Term Adjustment (PTA) is a process that adds time to the 20-year lifespan of a U.S. patent to compensate for certain delays caused by the USPTO during the patent application's prosecution. These delays can include the USPTO failing to issue a first office action within 14 months of filing, failing to respond to an applicant's reply within four months, or failing to issue a patent within three years of the application filing date, among other reasons. The calculation of PTA is typically performed by a computer program at the time the patent issues and is indicated in the Issue Notification Letter. Without direct access to the USPTO's Patent Center or Public Search for US9800633, I cannot provide the specific PTA granted for this patent.

• Patent Term Extension (PTE): Patent Term Extension (PTE) is available for patents covering certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products, to restore some of the patent term lost due to premarket government approval from a regulatory agency like the FDA. This patent, "Just-in-time distributed video cache," does not appear to relate to these categories of products. Therefore, it is highly unlikely to have received any Patent Term Extension.

• Continuation and Divisional Applications:

  • Continuation applications are subsequent applications filed by the same applicant, disclosing the same invention as a prior non-provisional application, and claiming priority to that prior application. They allow for continued prosecution of claims not allowed in the parent application.
  • Divisional applications are filed when an earlier application claimed two or more independent and distinct inventions, and the examiner required restriction to one of the inventions. A divisional application claims only subject matter disclosed in the parent application but directed to an invention not elected in the parent.
  • The patent indicates it is a divisional of U.S. patent application Ser. No. 13/945,747, filed on Jul. 18, 2013. This explicitly identifies a divisional application relationship. It also claims the benefit of U.S. Provisional Application No. 61/673,188, filed on Jul. 18, 2012. Without access to the full patent family tree on the USPTO database, I cannot determine if there are any further continuation or divisional applications directly stemming from US9800633 or its parent.

• Related Family Members: The patent states, "This application is a divisional of U.S. patent application Ser. No. 13/945,747, filed on Jul. 18, 2013, which claims the benefit of U.S. Provisional Application No. 61/673,188, filed on Jul. 18, 2012, which are incorporated by reference herein in their entirety." Therefore, US Patent Application Serial No. 13/945,747 and U.S. Provisional Application No. 61/673,188 are related family members.

• Projected Expiration Date:

  • The patent states a "Prior art date" of 2012-07-18 and a "Filing date" of 2015-09-04. It also states the patent "expires 2034-02-24".
  • For U.S. utility patents, the patent term is generally 20 years from the earliest claimed non-provisional filing date. The application Ser. No. 13/945,747, from which this patent is a divisional, was filed on July 18, 2013.
  • The Adjusted expiration date listed as 2034-02-24 suggests that the patent has received some amount of Patent Term Adjustment (PTA). The difference between the 20-year term from the 2013 filing date (July 18, 2033) and the adjusted expiration date (February 24, 2034) indicates a PTA of approximately 7 months and 6 days. This adjustment compensates for delays during prosecution by the USPTO.

To obtain the precise details of PTA, continuation/divisional applications beyond those explicitly stated, and a complete family tree, direct access to the USPTO's Patent Center for US9800633 would be required.
