Patent Term and Expiration Analysis

1. Patent Term Adjustment (PTA)

The patent has been granted a significant Patent Term Adjustment (PTA). The term of a U.S. patent is typically 20 years from the filing date of the earliest U.S. non-provisional application to which benefit is claimed.

• Earliest Priority Filing Date: March 24, 2011 (from application US 13/065,553).
• Calculated Standard Expiration Date: March 24, 2031 (20 years from the priority date).
• Adjusted Expiration Date: The patent documentation explicitly states an "Adjusted expiration" of March 2, 2034.

This adjustment indicates a PTA of 1,074 days, which has been granted by the USPTO to compensate for administrative delays that occurred during the patent's prosecution.

2. Patent Term Extension (PTE)

There is no information within the provided patent documentation to suggest that a Patent Term Extension (PTE) under 35 U.S.C. § 156 has been granted. PTE is typically associated with delays in regulatory review for products like pharmaceuticals and medical devices and is distinct from PTA.

3. Projected Expiration Date

The projected and official expiration date for U.S. Patent 10,912,321 is March 2, 2034. This date includes the full 20-year term calculated from the priority date plus the 1,074 days of awarded Patent Term Adjustment. This expiration is contingent upon the timely payment of all required maintenance fees.
