Analysis of Patent Term, Adjustments, and Family for U.S. Patent 10,664,518

As of May 4, 2026, the following analysis details the application history, patent term, and related family members for U.S. Patent No. 10,664,518.

Patent Term and Expiration

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

• Earliest Non-Provisional Filing Date: The '518 patent claims a chain of priority back to U.S. Provisional Application No. 61/892,238, filed on October 17, 2013. The first non-provisional application in this chain is U.S. Application No. 14/517,728, filed on October 17, 2014. This date is the basis for the patent term calculation.
• Base Expiration Date (20-Year Term): Counting 20 years from the earliest non-provisional filing date of October 17, 2014, the base expiration date for this patent is October 17, 2034.
• Patent Term Adjustment (PTA): There are no recorded Patent Term Adjustments (PTA) for U.S. Patent 10,664,518. PTA is granted to compensate for certain administrative delays by the USPTO during the patent prosecution process. The absence of a PTA means the term is not extended beyond the standard 20-year period.
• Patent Term Extension (PTE): There are no recorded Patent Term Extensions (PTE). PTE is typically granted for delays caused by regulatory review (e.g., by the FDA) and is not applicable to this patent's technology area.

Projected Expiration Date: Based on the earliest non-provisional filing date and the absence of any term adjustments or extensions, the projected expiration date for U.S. Patent 10,664,518 is October 17, 2034, assuming all required maintenance fees are paid on time.
