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

The USPTO does not calculate patent expiration dates or provide official PTA/PTE figures directly in its publicly searchable databases. However, general principles can be applied:

• Patent Term Adjustment (PTA): PTA compensates applicants for certain administrative delays by the USPTO during patent prosecution (35 U.S.C. § 154(b)). These delays can include the USPTO failing 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 the issue fee payment. PTA can also be granted if the patent is not issued within three years of its actual filing date. Applicant delays can reduce any awarded PTA.
• Patent Term Extension (PTE): PTE is distinct from PTA and is granted to compensate for delays incurred in obtaining regulatory approval for a patented product, particularly pharmaceuticals (35 U.S.C. § 156).

Given that US 11021737 relates to compositions and methods for analyte detection, which could be relevant to diagnostic products, a PTE might be sought if a product covered by the patent requires regulatory approval. Without access to the specific prosecution history and any potential regulatory approval details, the exact PTA and PTE for US 11021737 cannot be definitively stated.

Continuation, Divisional, and Related Family Members

To provide a comprehensive list of continuation and divisional applications, as well as related family members, a direct search of the USPTO Patent Center or other patent family databases is necessary. Based on the information available:

• Application Number: US16/941,585
• Publication Number (pre-grant): US20200354774A1
• Priority Date: December 22, 2011

The Google Patents entry for US 11021737 lists several "Other versions" and "Priority to" entries, which typically indicate related family members and continuations/divisionals. Based on this information:

• US20200354774A1: This is the pre-grant publication of US 11021737.
• Continuation Applications: The patent document itself indicates several "Priority to" entries which are US application numbers. These could represent continuation or divisional applications.
  • US17/122,168 (which issued as US11111521B2)
  • US17/238,642 (which issued as US11293051B2)
  • US17/238,682 (which issued as US11293052B2)
  • US17/366,151 (which issued as US11566276B2)
  • US17/366,127 (which issued as US11549136B2)
  • US17/498,829 (which published as US20220025448A1)
  • US17/584,959 (which issued as US11639518B2)
  • US17/671,803 (which issued as US11566277B2)
  • US17/664,095 (which published as US20220282301A1)
  • US18/064,956 (which issued as US11976318B2)
  • US18/146,483 (which published as US20230146985A1)
  • US18/459,068 (which published as US20240018569A1)
  • US18/614,970 (which published as US20240240235A1)
  • US18/936,042 (which published as US20250059590A1)
  • US18/989,119 (which published as US20250122556A1)
  • US18/989,169 (which published as US20250129408A1)

These applications generally represent continuations, continuations-in-part, or divisional applications, all of which claim priority back to an earlier application (in this case, likely US16/941,585 or its earliest priority application). A continuation application shares the same disclosure but pursues different claims, while a divisional application arises from a restriction requirement where a single application contains two or more independent inventions. A continuation-in-part (CIP) adds new subject matter while retaining some of the parent disclosure.

• International/PCT Applications:

  • PCT/US2012/071398 (Priority claimed from 2012-12-21, published as WO2013096851A1)
  • PCT/US2014/018580 (Priority claimed from 2014-02-26, published as WO2014163886A1)

• Foreign Equivalents:

  • ES23174395T (Priority to 2012-12-21, published as ES2991004T3)

Projected Expiration Date

The term of a U.S. utility patent (other than a design patent) is generally 20 years from the filing date of the earliest non-provisional application for which a benefit is claimed under 35 U.S.C. 120, 121, or 365(c).

US 11021737 claims priority from an application filed on December 22, 2011 (as indicated by the "Prior art date" and "Priority date" on the Google Patents page, which likely refers to an earlier application in the family). Assuming this date (December 22, 2011) is the earliest priority date from which the patent claims benefit, the base expiration date would be 20 years from this date.

Therefore, the anticipated expiration date, before any PTA or PTE, would be December 22, 2031.

However, the Google Patents page for US 11021737 explicitly lists an "Anticipated expiration" date of 2032-12-21. This suggests that at least one year of Patent Term Adjustment (PTA) has been granted to the patent, pushing the expiration beyond the standard 20 years from the earliest priority date. Without direct access to the USPTO's Patent Center for a detailed calculation, the date provided by Google Patents will be used as the projected expiration.
