Extensions

To determine the patent term adjustments (PTA), patent term extensions (PTE), continuation applications, divisional applications, related family members, and the projected expiration date for US patent 11988373, an in-depth search of the USPTO database, specifically Patent Center, is necessary. While some information can be inferred from general patent rules, the definitive details for this specific patent would be found within its official USPTO records.

Based on the provided patent text and general patent law:

• Patent Term Adjustment (PTA): Patent Term Adjustment is a process where the USPTO extends the patent term to compensate for certain administrative delays during the prosecution of a utility patent application. The total PTA is an addition to the 20-year lifespan of the issued patent. To determine the exact PTA for US11988373, one would need to access the official patent file history in the USPTO's Patent Center.

• Patent Term Extension (PTE): Patent Term Extension may be granted for certain types of patents, such as pharmaceuticals, to compensate for regulatory delays, for example, those related to FDA approval. The provided patent text does not indicate any such regulatory delays, and the patent's subject matter (light fixtures) typically does not qualify for PTE.

• Continuation Applications / Divisional Applications: The provided patent text for US11988373 indicates that it claims priority from Chinese Application No. CN 202320673598.5 filed on March 30, 2023. This is an earlier-filed application from which US11988373 claims priority. A patent granted on a continuation, divisional, or continuation-in-part application will have a term that expires 20 years from its "effective filing date," which is the filing date associated with the earliest non-provisional application or international (PCT) application from which it claims priority. To definitively identify any continuation or divisional applications directly stemming from US11988373 (rather than those it claims priority to), a search within the USPTO Patent Center for related applications would be needed.

• Related Family Members: The patent states that it claims priority from Chinese Application No. CN 202320673598.5. This Chinese application is a related family member. The Google Patents page also lists "CN219841425U" as being published as "CN202320673598.5U".

• Projected Expiration Date: Generally, the term of a U.S. utility patent begins on the issue date and expires 20 years from the date the application was originally filed, subject to any patent term adjustments or extensions. For US11988373:

  • Filing Date: 2023-05-23
  • Priority Date: 2023-03-30 (from Chinese Application No. CN 202320673598.5)
  • Issue Date: 2024-05-21

  Since the patent claims priority to an earlier application, its term is calculated from the priority date of the earliest application to which it claims benefit. In this case, the earliest priority date is March 30, 2023. Therefore, the anticipated expiration date is 20 years from this date, which would be March 30, 2043, assuming no patent term adjustments (PTA) or extensions (PTE) are applied. The patent record itself, as provided in the Google Patents link, states an "Anticipated expiration" of 2043-05-23. This suggests that the term is calculated from the US filing date (2023-05-23) rather than the earlier Chinese priority date, or that PTA has already been factored into this displayed date. For a definitive and precise expiration date including any PTA, the official USPTO Patent Center records for patent 11988373 would need to be consulted.
