Extensions

For US Patent 9516909, here's a detailed breakdown of its patent term, family members, and projected expiration:

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

• Patent Term Adjustments (PTA): PTA is designed to compensate patentees for delays caused by the USPTO during the prosecution of a patent application. This can add days to the standard 20-year patent term. The specific PTA for US9516909 is not detailed in the provided information, and the USPTO does not calculate expiration dates for patents, but provides a calculator as a resource.
• Patent Term Extensions (PTE): PTE is available under 35 U.S.C. § 156 for delays due to premarket regulatory review, typically for pharmaceutical products. There is no indication in the patent document or provided information that US9516909 is eligible for or has received any PTE.

Continuation Applications, Divisional Applications, and Related Family Members

US Patent 9516909 is part of a larger patent family, demonstrating a strategy of maintaining protection through continuation applications. A patent granted on a continuation or divisional application filed after June 8, 1995, has a term that ends 20 years from the filing date of the earliest application for which a benefit is claimed.

US9516909 is a continuation of and claims benefit to the following applications:

• U.S. application Ser. No. 14/927,093, filed Oct. 29, 2015, which issued as U.S. Pat. No. 9,289,022.

Projected Expiration Date

The patent states a "Priority date" of July 21, 2011, and an "Anticipated expiration" date of July 20, 2032.

Under U.S. patent law, for utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the earliest claimed non-provisional filing date. Since US9516909 claims benefit to applications with a priority date of July 21, 2011, the base 20-year term would typically end on July 21, 2031.

However, the "Anticipated expiration" date listed in the patent document as July 20, 2032, indicates that there has been a Patent Term Adjustment (PTA) of approximately one year (specifically, 365 days or close to it, if calculated from July 21, 2031). This adjustment would account for delays by the USPTO during prosecution.
