Extensions

US Patent 10,681,946, titled "Headband with protective insert," has several related applications and a projected expiration date.

Patent Term Adjustments (PTA) and Extensions (PTE)

The Google Patents legal status section indicates "Anticipated expiration: 2036-04-07". However, it does not explicitly detail any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE). PTA is granted to compensate for certain delays during patent prosecution by the USPTO, while PTE relates to delays due to regulatory review periods. To confirm the exact PTA, a direct review of the patent's file wrapper on the USPTO website would be necessary, as the USPTO does not calculate expiration dates for patents itself but provides tools for estimation.

Continuation and Divisional Applications

US Patent 10,681,946 is identified as a continuation of U.S. patent application Ser. No. 15/093,464, which itself claims priority to U.S. provisional patent application Ser. No. 62/147,437, filed April 14, 2015.

• US16/880,873 (US11627771B2)

These are all active applications stemming from the same priority date.

Projected Expiration Date

The Google Patents record for US10681946B2 indicates an "Anticipated expiration" date of 2036-04-07. A utility patent generally has a term that expires 20 years from its effective filing date, which for continuation applications is the filing date of the earliest application to which it claims priority under 35 U.S.C. § 120, § 121, § 365(c), or § 386(c). In this case, the earliest priority date is April 14, 2015, from the provisional application Ser. No. 62/147,437.

Calculating 20 years from the priority date of April 14, 2015, leads to an expiration date of April 14, 2035. However, the anticipated expiration date provided by Google Patents is April 7, 2036. This difference suggests that there has been a Patent Term Adjustment (PTA) applied to the patent, extending its term beyond the standard 20 years from the earliest priority date. Without access to the specific PTA calculation from the USPTO file history, the exact reason for the additional adjustment cannot be determined, but it is typically granted for delays caused by the USPTO during prosecution.
