Extensions

To determine the patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date for US Patent 12218934, we need to analyze the information from the patent itself and consult relevant USPTO resources.

1. Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate applicants for delays caused by the USPTO during the prosecution of a utility or plant patent application. The total PTA is added to the standard 20-year term from the earliest filing date. Factors leading to PTA include the USPTO failing to:

• Issue a first Official Action or notice of allowance within 14 months of filing.
• Issue an action within four months of an applicant's response.
• Issue the patent within four months of payment of the issue fee.
• Issue a patent within three years of the actual filing date (with some provisos).

The Google Patents page for US12218934B2 does not explicitly state the granted PTA. To get the precise PTA, one would typically need to examine the patent grant or the PAIR (Patent Application Information Retrieval) system on the USPTO website. However, based on the filing date of September 13, 2024, and the publication date of February 4, 2025, there was a relatively quick issuance. Without explicit PTA data, a precise calculation is not possible here.

2. Patent Term Extensions (PTE)

Patent Term Extension (PTE) is awarded to compensate for delays incurred in obtaining regulatory approval on a patented product, especially for drugs, biologics, or medical devices, under 35 U.S.C. § 156. PTE can extend a patent's life by up to five additional years.

US Patent 12218934, titled "Contextual and risk-based multi-factor authentication," is a software/computer-implemented invention related to network security. This type of patent is not typically eligible for PTE, as PTE is primarily for patents covering products subject to premarket government approval by regulatory agencies like the FDA. Therefore, it is highly unlikely that US12218934 has received or is eligible for PTE.

3. Continuation Applications, Divisional Applications, and Related Family Members

The "CROSS-REFERENCE TO RELATED APPLICATIONS" section of US12218934 provides a comprehensive list of its lineage, indicating that it is part of a large patent family:

• This application is a continuation of U.S. patent application Ser. No. 18/464,623, titled "RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Sep. 11, 2023.
• Which is a continuation of U.S. patent application Ser. No. 17/539,137, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Nov. 30, 2021 (issued as U.S. Pat. No. 11,757,872 on Sep. 12, 2023).
• Which is a continuation of U.S. patent application Ser. No. 16/856,827, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Apr. 23, 2020 (issued as U.S. Pat. No. 11,218,474 on Jan. 4, 2022).
• Which is a continuation of U.S. patent application Ser. No. 15/790,860, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Oct. 23, 2017 (issued as U.S. Pat. No. 10,742,647 on Aug. 11, 2020).
• Which claims priority to U.S. provisional patent application 62/574,708, titled "CONTEXTUAL AND RISK-BASED MULTI-FACTOR AUTHENTICATION," filed on Oct. 19, 2017.

Additionally, Ser. No. 15/790,860 is also a continuation-in-part of several other applications, which themselves have complex lineages, indicating a large family of related patents focusing on underlying technologies such as distributed computational graphs and cyberattack detection:

• U.S. patent application Ser. No. 15/616,427 (filed Jun. 7, 2017)
• U.S. patent application Ser. No. 14/925,974 (filed Oct. 28, 2015)
• U.S. patent application Ser. No. 15/237,625 (filed Aug. 15, 2016, issued as U.S. Pat. No. 10,248,910)
• U.S. patent application Ser. No. 15/206,195 (filed Jul. 8, 2016)
• U.S. patent application Ser. No. 15/186,453 (filed Jun. 18, 2016)
• U.S. patent application Ser. No. 15/166,158 (filed May 26, 2016)
• U.S. patent application Ser. No. 15/141,752 (filed Apr. 28, 2016, issued as U.S. Pat. No. 10,860,962)
• U.S. patent application Ser. No. 15/091,563 (filed Apr. 5, 2016, issued as U.S. Pat. No. 10,204,147)
• U.S. patent application Ser. No. 14/986,536 (filed Dec. 31, 2015, issued as U.S. Pat. No. 10,210,255)
• U.S. patent application Ser. No. 14/925,974 (filed Oct. 28, 2015)

The earliest priority date for US12218934, based on the cross-references, is October 28, 2015 (from U.S. patent application Ser. No. 14/925,974, which is referenced twice). The provisional application 62/574,708 (filed Oct. 19, 2017) is claimed as priority by Ser. No. 15/790,860, which is later in the chain than the October 28, 2015 date. Therefore, the effective earliest filing date for term calculation is October 28, 2015.

4. Projected Expiration Date

For utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the date on which the application for the patent was filed, or if it claims priority to an earlier application under 35 U.S.C. §§ 120, 121, 365(c), or 386(c), 20 years from the filing date of the earliest such application.

Given that US12218934 claims priority back to an application filed on October 28, 2015 (U.S. patent application Ser. No. 14/925,974), the statutory 20-year term would be calculated from this earliest effective filing date.

Therefore, the projected expiration date is:
October 28, 2015 (earliest priority date) + 20 years = October 28, 2035.

This date does not include any potential Patent Term Adjustment (PTA), as that information is not explicitly provided. If PTA were granted, it would extend the expiration date beyond October 28, 2035. However, the Google Patents page already lists an "Anticipated expiration" of "2035-10-28". This indicates that no significant PTA was granted or that any granted PTA was offset by applicant delay, or that it is simply a calculation based on the 20-year term from the earliest priority date without factoring in specific adjustments.
