As of May 13, 2026, this analysis details the patent term, application history, and projected expiration of U.S. Patent 12,118,290.

Patent Term Adjustments (PTA) and Extensions (PTE)

A review of the prosecution history for application number 18/357,451, which matured into patent 12,118,290, indicates that there has been no Patent Term Adjustment (PTA) granted by the USPTO. The application processing did not encounter delays attributable to the USPTO that would warrant an extension under 35 U.S.C. § 154(b).

There is no record of any Patent Term Extension (PTE) being sought or granted for this patent. PTEs, which typically compensate for regulatory review delays (e.g., by the FDA), are not applicable in this case.

Continuity and Related Applications

U.S. Patent 12,118,290 is part of a larger family of applications and claims the benefit of priority to several earlier filings. This relationship is critical for determining the patent's effective filing date and ultimate expiration.

The continuity chain, as detailed in the "Cross-Reference to Related Applications" section of the patent specification, is as follows:

• U.S. Patent 12,118,290 (the patent in question) issued from application 18/357,451, filed on July 24, 2023.
• Application 18/357,451 is a continuation of application 17/830,566, filed on June 2, 2022.
• Application 17/830,566 is a continuation of application 17/347,899, filed on June 15, 2021. This application has since issued as U.S. Patent 11,379,651.
• The entire family claims priority to U.S. Provisional Application 63/048,512, filed on July 6, 2020.

This chain establishes that the earliest non-provisional filing date, from which the 20-year patent term is calculated, is June 15, 2021.

Projected Expiration Date

The term of a U.S. utility patent is 20 years from the filing date of the earliest U.S. non-provisional application to which it claims priority.

• Earliest Non-Provisional Filing Date: June 15, 2021 (from application 17/347,899).
• Base Expiration Date (20 years later): June 15, 2041.
• Patent Term Adjustment (PTA): 0 days.

Therefore, the projected expiration date for U.S. Patent 12,118,290 is June 15, 2041, assuming all required maintenance fees are paid on schedule.
