Extensions

For US patent 9491564, a direct search of the USPTO database to retrieve specific details regarding Patent Term Adjustments (PTA), Patent Term Extensions (PTE), continuation applications, divisional applications, and related family members cannot be performed directly within this environment. While the USPTO's Patent Center is the authoritative source for such information, and Public PAIR (Patent Application Information Retrieval) has been retired, I cannot interactively navigate or parse dynamic web content from these portals to extract the specific data for this patent.

However, based on the initial information provided in the prompt from Google Patents, the anticipated expiration date for US9491564 is 2029-03-02.

General information regarding PTA and PTE is as follows:

• Patent Term Adjustment (PTA): PTA is granted to compensate for certain delays caused by the USPTO during the patent prosecution process. This adjustment adds time to the standard 20-year patent term from the filing date. Delays can include the USPTO taking more than 14 months to issue a first office action, acting more than four months after an applicant's reply, or taking more than four months after payment of the issue fee to grant the patent. The USPTO automatically determines the PTA and includes it in the Issue Notification Letter.
• Patent Term Extension (PTE): PTE is available for patents claiming products (e.g., human drugs, medical devices, food additives, or color additives), methods of using a product, or methods of manufacturing a product that have undergone a regulatory review period before commercial marketing or use by agencies like the FDA or USDA. The purpose of PTE is to restore some of the patent term lost during this premarket government approval process, with a maximum extension of five years.

Without direct access to the patent's file history in USPTO Patent Center, specific details on any PTA or PTE granted to US9491564 are unavailable. Similarly, information on any continuation or divisional applications, or other related family members, would typically be found within the patent's file wrapper, which is not accessible in this format.
