Patent Term Adjustments (PTA)

The precise Patent Term Adjustment (PTA) for US Patent 11878729 is not explicitly detailed in the provided patent text or direct search results from USPTO for this specific patent number. However, the "Anticipated expiration" date of 2029-12-04, as stated on the Google Patents page, suggests that Patent Term Adjustment has been applied. Utility patents typically have a term of 20 years from the earliest claimed priority date. The earliest priority date for US11878729 is December 4, 2008, meaning the base expiration date would be December 4, 2028 (20 years from 2008-12-04). The difference between the anticipated expiration date (2029-12-04) and this base date (2028-12-04) indicates an adjustment of approximately one year, which would be due to PTA. PTA is granted to compensate for certain administrative delays by the USPTO during the patent prosecution process.
