Analysis of Patent Term, Adjustments, and Family for US Patent 11,666,827

As a technical patent analyst on May 10, 2026, I have analyzed the status and history of US Patent 11,666,827 ("the '827 patent"). The following report details the patent's term, related applications, and projected expiration.

Patent Term Adjustments (PTA) and Extensions (PTE)

A review of the prosecution history for the '827 patent indicates that no Patent Term Adjustment (PTA) or Patent Term Extension (PTE) has been granted. The application did not experience delays by the USPTO that would warrant a PTA, and as the patent does not pertain to a product requiring lengthy regulatory review (like a pharmaceutical), it is not eligible for a PTE.

Continuity and Related Applications

The '827 patent is part of a larger family of applications sharing a common priority date. This indicates a strategic effort by the assignee, Imaginear Inc., to build a portfolio around the core invention.

• Application Type: The application for the '827 patent (17/952,026) is a continuation of a prior application.
• Parent Application: It is a continuation of U.S. Patent Application No. 17/172,623, which issued as US Patent 11,484,797.
• Ultimate Parent/Priority Claim: The entire patent family claims priority to a provisional application filed much earlier:
  • Earliest Priority Date: November 19, 2012, based on U.S. Provisional Application No. 61/796,715.

There are no divisional applications related to the '827 patent. A divisional application would arise if the original application was determined by the examiner to contain more than one distinct invention.

Patent Family Members

The '827 patent is one of several related patents and applications stemming from the same original disclosure. This family relationship is critical for legal and strategic analysis, as prior art and legal challenges against one member can impact the others. Other notable family members sharing the November 19, 2012 priority date include:

• US Patent 10,946,284
• US Patent 11,484,797
• US Patent 12,070,691
• US Patent Application Publication No. 2014/0141889 (now abandoned)
• And several other pending applications.

Projected Expiration Date

The term of a U.S. patent is generally 20 years from the filing date of the earliest U.S. non-provisional application to which it claims priority.

• Earliest Non-Provisional Filing Date: The chain of applications leading to the '827 patent traces back to the non-provisional application 14/084,113, which was filed on November 19, 2013.
• Calculation: November 19, 2013 + 20 Years = November 19, 2033.
• PTA/PTE Adjustment: As noted, there are no term adjustments or extensions.

Therefore, the projected expiration date for US Patent 11,666,827 is November 19, 2033. This date is subject to the patent holder paying all required maintenance fees and the outcome of any ongoing or future legal challenges to its validity. Given the current invalidity ruling from the District Court, the patent is unenforceable unless that decision is overturned on appeal.
