Extensions — US Patent 11149306

To provide a comprehensive answer regarding US patent 11149306, I will gather information directly from the USPTO database.

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

To determine any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE), a detailed examination of the patent's prosecution history in the USPTO Patent Center would be required. PTA is granted to compensate for certain delays by the USPTO during patent prosecution, while PTE applies to certain drug, biologic, animal drug, and medical device patents to compensate for regulatory review periods. The provided patent text and general searches do not explicitly state the PTA or PTE for US11149306.

Continuation and Divisional Applications

The patent text indicates that US11149306 is a continuation of several earlier applications, establishing its lineage within a patent family. A continuation application is filed before the patenting, abandonment, or termination of proceedings on an earlier application, and it discloses the same invention as the prior application. A divisional application is also for an invention disclosed in a prior-filed copending nonprovisional application, where the original application contained more than one independent and distinct invention.

According to the "CROSS-REFERENCE" section of US11149306, it is:

a continuation of U.S. application Ser. No. 16/601,168, filed Oct. 14, 2019 (now U.S. Pat. No. 10,801,063, issued Oct. 13, 2020).
which is a continuation of U.S. application Ser. No. 15/892,178, filed Feb. 8, 2018 (now U.S. Pat. No. 10,883,139, issued Jan. 5, 2021).
which is a continuation of U.S. application Ser. No. 14/861,989, filed Sep. 22, 2015 (now U.S. Pat. No. 9,920,366, issued Mar. 20, 2018).
which is a continuation application of International Application No. PCT/US2014/072383, filed Dec. 24, 2014.
which claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 61/921,456, filed Dec. 28, 2013, and U.S. Provisional Application No. 61/948,509, filed Mar. 5, 2014.

Therefore, US11149306 is a continuation application, and its earliest effective filing date for term calculation purposes is December 24, 2014, corresponding to International Application No. PCT/US2014/072383. This is because domestic benefit under 35 U.S.C. 119(e) to provisional applications is not considered in the calculation of the twenty-year term.

Related Family Members

The patent family refers to all patents and patent applications that cover the same or similar invention. Based on the cross-reference information, the following are direct family members related to US11149306:

U.S. Pat. No. 10,801,063 (from application Ser. No. 16/601,168)
U.S. Pat. No. 10,883,139 (from application Ser. No. 15/892,178)
U.S. Pat. No. 9,920,366 (from application Ser. No. 14/861,989)
International Application No. PCT/US2014/072383
U.S. Provisional Application No. 61/921,456
U.S. Provisional Application No. 61/948,509

The Google Patents record also shows "Other versions" including US20200362405A1. A PubChem entry lists AU-2014369841-A1 as part of the patent family.

Projected Expiration Date

The term of a U.S. utility patent for applications filed on or after June 8, 1995, generally ends 20 years from the filing date of the earliest application for which a benefit is claimed under 35 U.S.C. 120, 121, 365(c), or 386(c). This means the term is calculated from the earliest non-provisional filing date in its priority chain.

In this case, the earliest non-provisional application for which benefit is claimed is International Application No. PCT/US2014/072383, filed on December 24, 2014.

Therefore, the base patent term would extend 20 years from December 24, 2014.

Expiration Date = December 24, 2014 + 20 years = December 24, 2034.

This calculation does not include any potential Patent Term Adjustments (PTA) or Patent Term Extensions (PTE), which could prolong the patent's life. The Google Patents information for US11149306 lists "2034-12-24 Anticipated expiration" which aligns with this calculation.
