Extensions

To provide a comprehensive overview of US Patent 11275092, I will use the USPTO resources to gather detailed information on its prosecution history and projected expiration.

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

• Patent Term Adjustment (PTA): PTA is designed to compensate patent owners for delays caused by the USPTO during the prosecution of a utility or plant patent application. The total PTA is added to the standard 20-year patent term from the earliest filing date. Delays that can trigger PTA include failure by the USPTO to: issue a first Office Action or Notice of Allowance within 14 months of filing; respond to an applicant's reply within four months; or issue the patent within four months of payment of the issue fee. The patent term will also be extended if the USPTO fails to issue a patent within three years of the actual filing date. However, applicant delays can reduce any accrued PTA.
  • To determine the specific PTA for US11275092, a direct calculation using the USPTO's official records (Patent Center or a specific PTA determination notice for this patent) would be necessary. Such a calculation would involve analyzing the prosecution history against the statutory timeframes.
• Patent Term Extension (PTE): PTE, established under the Hatch-Waxman Act, is available for patents claiming certain human drug products, medical devices, animal drugs, and food or color additives. It aims to restore some of the patent term lost due to pre-market government regulatory review by agencies like the FDA. PTE is limited to a maximum of five years, and the total patent life with a PTE cannot exceed 14 years from the date of FDA approval. Only one patent can be extended per regulatory review period.
  • Given that US11275092 relates to methods for determining a treatment protocol and prognosis for brain injury using tau protein biomarkers, it could potentially be eligible for PTE if the tau protein measurement or a related therapeutic product claimed by the patent requires FDA approval. However, the available information does not specify if a PTE has been applied for or granted for this patent.

Continuation and Divisional Applications:

• US Patent 11275092 is explicitly identified as a continuation of U.S. patent application Ser. No. 15/269,142, filed Sep. 19, 2016. This, in turn, is a continuation of U.S. patent application Ser. No. 14/111,326, filed Jun. 24, 2014, which itself is a national stage of International Patent Application Ser. No. PCT/US2012/033343, filed Apr. 12, 2012. The international application claims priority to U.S. Provisional Patent Application Ser. No. 61/474,315, filed Apr. 12, 2011, and U.S. Provisional Patent Application Ser. No. 61/524,693, filed Aug. 17, 2011.
• No specific divisional applications are mentioned in the provided text for US11275092.

Projected Expiration Date:

• The Google Patents entry for US11275092B2 states its "Adjusted expiration" date is June 17, 2032.
• The standard patent term for utility patents filed on or after June 8, 1995, is 20 years from the earliest filing date (or priority date in the case of continuations/divisionals). Since the earliest priority date for US11275092 is April 12, 2011 (U.S. Provisional Patent Application Ser. No. 61/474,315), a 20-year term from this date would suggest an expiration around April 12, 2031. The stated "Adjusted expiration" of June 17, 2032 implies that a Patent Term Adjustment (PTA) has been granted, adding approximately 1 year and 2 months to the patent term.
