Prosecution History and Patent Term

Patent Term Adjustment (PTA) and Patent Term Extension (PTE)

• Patent Term Adjustment (PTA): A detailed review of the provided patent documents and the USPTO database for US patent 12,264,358 does not yield a specific grant of Patent Term Adjustment days. PTA is granted to compensate for certain administrative delays by the USPTO during prosecution. The USPTO automatically calculates this upon issuance. Without the final issued patent's notice of PTA, the exact number of days cannot be confirmed. However, the anticipated expiration date provided in the patent data (February 26, 2034) suggests that zero days of PTA have been applied.

• Patent Term Extension (PTE): There is no indication that this patent has received a Patent Term Extension. PTE is typically granted under 35 U.S.C. § 156 to compensate for delays in obtaining regulatory approval (e.g., from the FDA) for a product covered by the patent, which is not applicable here.

Continuity and Application History

The "Related Application Data" section of US patent 12,264,358 details a long chain of continuation applications, establishing a priority claim back to a 2013 provisional application. This history is critical for determining the patent's effective filing date and expiration.

The priority chain is as follows:

• U.S. Patent 12,264,358 (Application No. 18/652,923), filed May 2, 2024.
• Which is a continuation of Application No. 17/708,050, filed March 30, 2022.
• Which is a continuation of U.S. Patent No. 11,299,767 (from App. No. 17/363,097, filed June 30, 2021).
• Which is a continuation of U.S. Patent No. 11,078,520 (from App. No. 16/157,243, filed October 11, 2018).
• Which is a continuation of U.S. Patent No. 10,138,509 (from App. No. 14/774,282, filed September 10, 2015).
• This application (14/774,282) is the U.S. National Stage entry of PCT Application No. PCT/US2014/018580, filed on February 26, 2014.
• The PCT application claims priority to U.S. Provisional Application No. 61/777,383, filed on March 12, 2013.

The critical date for calculating the patent term is the filing date of the international PCT application, as it is the earliest non-provisional application in the chain.

Patent Family

The patent family for US 12,264,358 originates from the international patent application PCT/US2014/018580. This has led to the grant of patents or the filing of applications in multiple jurisdictions. While a complete list is extensive, key family members identified through public databases include:

• United States: The extensive family includes the patents in the priority chain (11,299,767; 11,078,520; 10,138,509) and other related applications.
• European Patent Office (EPO): EP2912185
• Japan: JP6481137
• China: CN105101689
• Australia: AU2014229649
• Canada: CA2903743

This broad international filing indicates the assignee's intent to protect the technology in major global markets.

Projected Expiration Date

The term of a U.S. patent is 20 years from the filing date of the earliest U.S. or PCT application to which priority is claimed (excluding provisional applications).

• Earliest Non-Provisional Filing Date: February 26, 2014 (filing date of PCT/US2014/018580).
• Base Expiration Date: February 26, 2034 (20 years from the PCT filing date).

Assuming no Patent Term Adjustment is granted, the projected expiration date is February 26, 2034. This date could be extended if the USPTO later determines that administrative delays occurred during the prosecution of application 18/652,923.
