Extensions

As a technical patent analyst, I've gathered the following information regarding US Patent 11447993B1:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate for delays caused by the USPTO during the prosecution of a patent application. This adjustment adds to the standard 20-year patent term from the filing date. The USPTO automatically determines the PTA and issues a notice with the patent.

To determine the specific PTA for US11447993B1, a direct query to the USPTO Patent Center or a review of the patent's electronic file wrapper would be necessary. The provided information does not explicitly state the PTA for this patent.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are available for patents claiming certain human drug products, medical devices, animal drugs, or food/color additives to restore time lost due to premarket government approval.

Given that US11447993B1 is titled "Door security device" and pertains to mechanical security, it is highly unlikely to be eligible for a Patent Term Extension under 35 U.S.C. § 156, as it does not fall into the categories of products requiring premarket regulatory approval. There is no indication in the provided patent information that a PTE has been applied for or granted for this patent.

Continuation and Divisional Applications

• Continuation Applications: A patent granted on a continuation application filed on or after June 8, 1995, will have a term ending 20 years from the filing date of the earliest application for which a benefit is claimed.
• Divisional Applications: Similar to continuation applications, a patent granted on a divisional application filed on or after June 8, 1995, will also have a term ending 20 years from the filing date of the earliest application for which a benefit is claimed.

The provided patent information for US11447993B1 lists the following priority applications and related child applications:

• US17/532,418: This is the application number for US11447993B1 itself, filed on 2021-11-22.
• US17/881,025 (US11619083B1): This is listed as a "Continuation" application with a priority date of 2021-11-22 and a filing date of 2022-08-04. This indicates that US11619083B1 is a continuation of US17/532,418 (the application for US11447993B1).
• US18/114,385 (US12173535B2): This is also listed as having a priority date of 2021-11-22 and a filing date of 2023-02-27. While not explicitly labeled "continuation" or "divisional" in the same way as US17/881,025, its priority to the original filing date suggests it is a related family member (likely a continuation or divisional).

Related Family Members

The patent explicitly lists the following related family members:

• US11447993B1 (this patent)
• US11619083B1 (a continuation of the application for US11447993B1)
• US12173535B2 (a further related application, also claiming priority to the original filing date of US11447993B1's application)

Projected Expiration Date

The standard term for U.S. utility patents issued from applications filed on or after June 8, 1995, is 20 years from the earliest filing date of the application, subject to any patent term adjustments or extensions.

For US11447993B1:

• Filing Date: 2021-11-22
• Standard 20-year term expiration: 2041-11-22

The patent information provided already states an "Anticipated expiration" date of 2041-11-22, which aligns with the standard 20-year term from the filing date. This date would be adjusted by any Patent Term Adjustment (PTA) that might have been granted due to USPTO delays during prosecution. Without specific PTA data, the anticipated expiration remains the 20-year mark from the filing date.
