Extensions

US Patent 12239333, titled "Single insertion delivery system for treating embolism and associated systems and methods," was granted on March 4, 2025, and filed on October 30, 2023.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate patent applicants for delays caused by the USPTO during the prosecution of a patent application. This can extend the 20-year lifespan of a patent. Delays can include the USPTO failing to:

• Issue a first office action or notice of allowance within 14 months of filing.
• Respond to an applicant's reply to an office action within four months.
• Issue the patent within four months of paying the issue fee.
• Issue a patent within three years of the actual filing date.

The total PTA is the sum of these delays, minus any delays caused by the applicant. The patent text for US12239333 does not explicitly state the amount of PTA awarded. To determine the exact PTA, one would typically need to consult the patent's file history on the USPTO Patent Center.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are available for patents claiming certain human drug products, medical devices, animal drugs, veterinary biological products, and food or color additive products. This extension aims to restore some of the patent term lost while awaiting premarket government approval from a regulatory agency like the FDA.

The patent text for US12239333 does not indicate that a Patent Term Extension (PTE) has been applied for or granted. Given that the patent relates to medical devices for treating embolisms, it could be eligible for PTE if it underwent a regulatory review period with a government agency prior to commercial marketing. However, without specific information within the patent document or its associated legal status on the USPTO, no PTE can be confirmed.

Continuation and Divisional Applications

The patent states in its "CROSS-REFERENCE TO RELATED APPLICATION" section that it is a continuation of:

• U.S. patent application Ser. No. 17/865,307, filed on Jul. 14, 2022.
• U.S. patent application Ser. No. 17/498,642, filed on Oct. 11, 2021.
• U.S. patent application Ser. No. 16/258,344, filed on Jan. 25, 2019, which is now issued as U.S. Pat. No. 11,154,314.

It also claims the benefit of:

• U.S. Provisional Patent Application No. 62/622,691, filed on Jan. 26, 2018.

This indicates that US12239333 is a continuation application, building upon previous applications. The document does not mention any divisional applications.

Related Family Members

Based on the continuation chain provided in the patent text, the related family members include:

• U.S. patent application Ser. No. 17/865,307
• U.S. patent application Ser. No. 17/498,642
• U.S. Pat. No. 11,154,314 (from U.S. patent application Ser. No. 16/258,344)
• U.S. Provisional Patent Application No. 62/622,691

The Google Patents page also lists other versions: US20240074771A1. Additionally, it shows priority to US19/011,529 (patent/US20250213259A1/en), US19/030,673 (patent/US20250325291A1/en), and US19/030,209 (patent/US20250281192A1/en).

Projected Expiration Date

The standard term for a U.S. utility patent is 20 years from its earliest filing date. Since US12239333 claims priority to U.S. Provisional Patent Application No. 62/622,691, filed on January 26, 2018, this date would typically be the starting point for calculating the 20-year term.

Therefore, without any Patent Term Adjustment (PTA) or Patent Term Extension (PTE), the patent would expire on January 26, 2038.

However, the Google Patents information page for US12239333 lists an "Anticipated expiration" date of 2039-01-25. This suggests that there has been a Patent Term Adjustment (PTA) of approximately one year. This adjustment accounts for delays by the USPTO during the examination process. This "Anticipated expiration" date of 2039-01-25 takes precedence as the current ground truth. [cite: Patents.google.com]
