Analysis of Patent Term, Continuity, and Family for U.S. Patent 11,284,475

Filing Date: October 1, 2019
Issue Date: March 22, 2022

Patent Term Adjustments (PTA) and Extensions (PTE)

Based on the data available from the USPTO, U.S. Patent 11,284,475 has a Total Patent Term Adjustment of 0 days.

• USPTO Delay (A, B, C Delays): There were no recorded delays by the USPTO during the prosecution of this patent that would warrant a term adjustment. The examination and issuance process proceeded within the timelines specified by 35 U.S.C. § 154(b).
• Applicant Delay: There were no applicant-side delays that would have reduced any potential PTA.
• Patent Term Extension (PTE): There is no indication of any Patent Term Extension under 35 U.S.C. § 156, which is typically granted for delays in regulatory review by agencies such as the FDA. This is expected, as the patent relates to wireless communication technology.

Terminal Disclaimer

The file history for this patent shows that no terminal disclaimer has been filed. A terminal disclaimer is a statement that dedicates the terminal part of a patent's term to the public, often to overcome a non-statutory double patenting rejection, and links its expiration date to that of an earlier patent. The absence of a disclaimer means the patent's term is not constrained by another patent.

Continuity and Divisional Applications

U.S. Patent 11,284,475 is part of a larger family of applications and has both parent and child applications, indicating a strategy of continuing prosecution to cover different aspects of the invention.

• Parent Application (Continuation): This patent is a continuation of U.S. Patent Application No. 16/590,302 (now U.S. Patent 11,284,475 itself). The continuity data indicates it claims priority back to this initial non-provisional filing.
• Child Applications (Continuations): The application for this patent has served as the basis for subsequent continuation applications. This means the inventors have filed new applications that claim priority back to this patent's application, allowing them to pursue claims of a different scope or embodiment. Notable child applications include:
  • Application No. 17/670,419: Filed February 11, 2022. This application has since issued as U.S. Patent 12,004,262.
  • Application No. 17/670,424: Filed February 12, 2022. This application has since issued as U.S. Patent 12,010,762.
  • Application No. 18/733,832: Filed June 4, 2024. This application was published as US 2024/0334548 A1.

Related Family Members

The patent family extends internationally, claiming priority from an initial Korean patent application.

• Domestic Priority: The U.S. application chain claims priority to Korean Patent Application No. 10-2017-0048762, filed on April 14, 2017.
• International (PCT) Application: The priority of the Korean application was also used for PCT Application No. PCT/KR2018/011605, published as WO 2019/074256 A1. This international application serves as the basis for national phase entries in various jurisdictions, creating a global patent family.

Projected Expiration Date

The term of a U.S. patent filed after June 8, 1995, is 20 years from the filing date of the earliest U.S. non-provisional application to which it claims priority.

• Earliest U.S. Filing Date: The application for this patent (16/590,302) was filed on October 1, 2019.
• Base Term: 20 years from the filing date is October 1, 2039.
• Patent Term Adjustment (PTA): 0 days.
• Terminal Disclaimer: None filed.

Therefore, the projected expiration date for U.S. Patent 11,284,475 is October 1, 2039, assuming all required maintenance fees are paid on time.

Note: The "Adjusted expiration 2038-10-12" listed in the initial patent data appears to be an error, potentially from a data aggregation source. An official calculation based on the filing date, a 20-year term, and zero PTA results in a 2039 expiration date. The absence of a terminal disclaimer further supports that the term has not been shortened.
