Extensions

For US Patent 10,549,648, the following details regarding patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and projected expiration date can be identified:

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

The precise amount of Patent Term Adjustment (PTA) or Patent Term Extension (PTE) for US 10,549,648 is not explicitly provided in the available search results from the USPTO database or Google Patents. The USPTO generally does not calculate and publish the exact expiration date for patents, instead providing tools and guidance for patentees to estimate it.

Patent Term Adjustment (PTA) is granted to compensate for certain delays caused by the USPTO during the prosecution of a utility or plant patent application, adding time to the standard 20-year term from the earliest claimed filing date. Patent Term Extension (PTE), on the other hand, is applicable to patents on products requiring premarket government approval (e.g., human drugs, medical devices) to restore time lost during regulatory review. The patent (US10549648) describes a "vehicle propulsion system," which does not appear to fall under the categories eligible for PTE under 35 U.S.C. § 156.

Given that the "Anticipated expiration" listed on Google Patents for US10549648 is January 30, 2034, which is exactly 20 years from its earliest priority date of January 30, 2014, it suggests that either no significant PTA was awarded, or the provided expiration date does not factor in any PTA that might have been granted.

Continuation Applications, Divisional Applications, and Related Family Members

US Patent 10,549,648 (which originated from application US16/555,487, filed on August 29, 2019) is part of a patent family with several related applications. The patent's earliest priority date is January 30, 2014.

Based on the Google Patents legal events and associated links, US 10,549,648 is related to the following applications/patents:

• Application Publication: US20190381897A1, published on December 19, 2019, is the application publication for US 10,549,648.
• Family Members Claiming Priority from US10549648's Application:
  • US16/725,151, with a "Priority to" event dated December 23, 2019, leading to US10933754B2. This indicates that application US16/725,151 (which later matured into US10933754B2) claims priority from the application that led to US10549648 (US16/555,487), making it a likely continuation or divisional application.
  • US17/163,646, with a "Priority to" event dated February 1, 2021, leading to US11351874B2. Similarly, application US17/163,646 (which later matured into US11351874B2) also claims priority from the application that led to US10549648 (US16/555,487), suggesting it is another continuation or divisional application within the same family.

These subsequent applications (US10933754B2 and US11351874B2) are continuations or divisional applications because they were filed after the parent application (US16/555,487) and claim priority back to it, sharing the same effective filing date for common subject matter.

Projected Expiration Date

The projected expiration date for US 10,549,648, as listed on Google Patents, is January 30, 2034. This date is calculated as 20 years from the earliest priority date of January 30, 2014, in accordance with 35 U.S.C. § 154(a)(2) for utility patents filed on or after June 8, 1995. Without specific PTA data from official USPTO records, this remains the best available estimate for the patent's expiration.
