Extensions

A utility patent generally has a term of 20 years from its earliest filing date, but this can be affected by Patent Term Adjustments (PTA) or Patent Term Extensions (PTE). PTA compensates for delays during prosecution by the USPTO, while PTE is granted for delays in regulatory approval of a patented product.

For US patent 10348471:

• Patent Term Adjustments (PTA): The provided patent text does not explicitly state whether any Patent Term Adjustments were granted to US10348471. To determine the exact PTA, a direct examination of the patent's issue certificate or the Private PAIR system at the USPTO would be necessary.
• Patent Term Extensions (PTE): There is no information in the provided patent text indicating that US10348471 has received any Patent Term Extensions. PTEs are typically associated with patents covering products subject to regulatory review, such as pharmaceuticals.
• Continuation Applications: The patent text lists "Priority to US15/231,638" on 2016-08-08, and "Priority to US16/449,245" on 2019-06-21. It also lists "Priority to US17/183,239" on 2021-02-23 and "Priority to US18/348,728" on 2023-07-07. These indicate a chain of related applications. The application number for US10348471 is US15/231,638. Therefore, US16/449,245, US17/183,239, and US18/348,728 are likely continuation or divisional applications claiming priority from US15/231,638.
• Divisional Applications: Based on the priority claims, it is possible that some of the later-filed applications (US16/449,245, US17/183,239, US18/348,728) are divisional applications, which arise from restriction requirements in a prior-filed application.

The Google Patents record for US10348471 also lists an "Anticipated expiration" date of 2036-08-08 [cite: The provided patent text]. This date would be adjusted by any awarded PTA or PTE.
