Extensions — US Patent 11731682

For US Patent 11731682, the following details are available based on the provided patent text and current understanding of patent law:

Patent Term Adjustment (PTA): The official patent document from Google Patents lists an "Anticipated expiration" date of 2029-12-08. Given the earliest priority date of 2008-12-04, a standard 20-year patent term would typically expire on 2028-12-04. The difference between these dates (approximately 1 year and 4 days) indicates that the patent has likely received a Patent Term Adjustment. PTA is granted to compensate for certain delays by the U.S. Patent and Trademark Office (USPTO) during patent prosecution. The exact calculation of PTA is automatically determined by the USPTO and typically included in the Issue Notification Letter. Without direct access to the USPTO's Patent Center records for this specific patent's Issue Notification, the precise PTA calculation cannot be confirmed beyond what is inferred from the expiration date.
Patent Term Extension (PTE): This patent pertains to a "Removable seat attachment for a stroller." Patent Term Extensions are generally available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to account for time lost during premarket government approval by a regulatory agency like the FDA. As the invention does not fall into these categories, it is highly unlikely to have received a Patent Term Extension, and no such extension is indicated in the provided patent information.
