Extensions

The USPTO website (uspto.gov) is the authoritative source for patent information. I will search the USPTO Patent Center for US patent 11673805 to find the requested details.

Patent Term Adjustments (PTA) and Patent Term Extensions (PTE)

Patent Term Adjustment (PTA) can extend the term of a U.S. utility patent to compensate for delays in prosecution caused by the USPTO. It applies to applications filed on or after May 29, 2000. The calculation for PTA considers USPTO delays (e.g., failing to issue a first office action within 14 months, or the patent within 3 years of the filing date) and reduces it for applicant-caused delays.

Patent Term Extension (PTE) is granted under 35 U.S.C. 156 for patents on certain products (like human drugs, medical devices, food additives) to account for time lost during premarket government approval from regulatory agencies such as the FDA.

To definitively determine if US11673805 has received any PTA or PTE, direct access to the official USPTO Patent Center for this specific patent's "Patent Term Adjustments" section or the patent's "Issue Notification" is required. Based on the provided search results, the full text of US11673805, or its Google Patents entry, I cannot find explicit details regarding any PTA or PTE applied to this patent. Such information is usually detailed on the face of the issued patent or within the patent's prosecution history available via Patent Center.

Continuation Applications and Divisional Applications

• Continuation Application: A continuation application discloses the same invention(s) as a prior-filed, copending non-provisional application, without introducing new subject matter.
• Divisional Application: A divisional application is filed when an earlier application claimed more than one independent and distinct invention.

The provided patent text indicates that US11673805 (application number US17/399,277) claims priority to European patent application EP 20020366, filed August 11, 2020. It also mentions a related child application, US17/523,970, which is a Continuation-In-Part (CIP) application. A Continuation-in-Part is a type of continuation application.

Therefore, US11673805 has at least one related application:

• US17/523,970: This is listed as a Continuation-In-Part, filed on November 11, 2021, and published as US20230053006A1.

Projected Expiration Date

The "Legal status" section of US11673805B2 states that the patent is "Active, expires 2041-08-12". This date already accounts for any standard adjustments, but without explicit PTA/PTE data, it's presumed to be the current, adjusted expiration date.
