Patent Term Adjustments and Extensions:

As of May 10, 2026, there are no recorded Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) for U.S. Patent No. 9,151,557. The United States Patent and Trademark Office (USPTO) can grant a PTA to compensate for certain delays caused by the USPTO during the patent prosecution process. A PTE is a different type of extension, typically granted for patents related to products that undergo a lengthy regulatory review process, such as pharmaceuticals.

Continuation and Divisional Applications:

A review of the patent documentation and public records indicates that U.S. Patent No. 9,151,557 is not a continuation or a divisional application of any prior non-provisional application. It does, however, claim priority to a provisional application.

Patent Family Information:

This patent does not have any direct foreign counterparts or other related U.S. patents that would constitute a patent family. The invention is only protected by this single U.S. patent.

Projected Expiration Date:

For utility patents filed after June 8, 1995, the term is generally 20 years from the earliest non-provisional filing date. Since U.S. Patent No. 9,151,557 was filed on May 13, 2014, and there are no adjustments or extensions, its projected expiration date is May 13, 2034. It is important to note that this expiration is contingent upon the timely payment of all required maintenance fees. These fees are due at 3.5, 7.5, and 11.5 years from the date of issue. Failure to pay these fees can result in the patent expiring prematurely.
