Extensions

US patent 11261566 has the following details regarding its term and family:

Patent Term Adjustments (PTA) and Extensions (PTE):

• Patent Term Adjustment (PTA): The USPTO grants Patent Term Adjustments to extend the term of a utility or plant patent to compensate for certain delays caused by the USPTO during the patent application's prosecution. These delays include, but are not limited to, failing to issue a first office action or notice of allowance within 14 months of filing, failing to respond to an applicant's reply within four months, or failing to issue the patent within four months of the issue fee payment. The total PTA is added to the standard 20-year lifespan of the patent. The USPTO automatically determines the PTA and transmits a notice of determination no later than the patent's issue date. While the provided information mentions the existence and calculation of PTA, it does not specify the exact PTA granted for US11261566.
• Patent Term Extension (PTE): Patent Term Extensions are available for certain types of patents, such as pharmaceuticals, to compensate for regulatory delays, like those from the FDA. The provided information for US11261566 does not indicate any Patent Term Extensions.

Continuation and Divisional Applications:
The patent document US11261566B2 itself refers to its application number as US16/980,449, which was filed on March 11, 2019. The priority date for this patent is March 15, 2018. Generally, a patent granted on a continuation or divisional application filed after June 8, 1995, will have a term that ends 20 years from the filing date of the earliest application for which a benefit is claimed. The provided information does not explicitly state whether US11261566 is a continuation or divisional application of an earlier U.S. application. However, the presence of an earlier priority date (2018-03-15) than its filing date (2019-03-11) suggests it likely claims priority from an earlier application (potentially a provisional or foreign application).

Projected Expiration Date:
The general rule for utility patents is that the term begins on the date the patent issues and expires 20 years from the date the application was originally filed. If the application claims priority to an earlier filed application, the 20-year term is calculated from the earliest claimed priority date.

For US11261566:

• Application Filing Date: March 11, 2019.
• Priority Date: March 15, 2018.

Assuming the 20-year term is calculated from the earliest priority date (March 15, 2018), and without any Patent Term Adjustment (PTA) information available from the provided snippets, the anticipated expiration date for US11261566 would be March 15, 2038. The patent document also lists an "Anticipated expiration" date of March 11, 2039. This discrepancy could be due to Patent Term Adjustment (PTA) or if the earliest priority claim for calculating the 20-year term is tied to the U.S. filing date rather than the earlier priority date, or a different earlier U.S. non-provisional or PCT application. To confirm the exact expiration date, a detailed review of the patent's prosecution history on the USPTO website would be necessary to determine any granted PTA.
