Extensions

To provide a comprehensive overview of patent term adjustments, extensions, family members, and the projected expiration date for US Patent 7793332, I will access the USPTO's Patent Center (formerly Public PAIR) and Assignment Center. These are the authoritative sources for such information directly from the USPTO.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can extend the term of a U.S. patent to compensate for certain delays by the USPTO during the prosecution of a utility or plant patent application. This applies to applications filed on or after May 29, 2000.
Since US Patent 7793332 was filed on June 7, 1995, it is not eligible for Patent Term Adjustment (PTA) as it predates the May 29, 2000, effective date for PTA provisions.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost during premarket government approval from a regulatory agency.
Based on the subject matter of US Patent 7793332, which relates to signal processing apparatus and methods for electronic communication, it is not eligible for Patent Term Extension (PTE) under 35 U.S.C. § 156, as it does not cover products requiring regulatory approval from agencies like the FDA.

Continuation Applications

A continuation application allows an applicant to pursue new claims based on the same specification and drawings as a previously filed "parent" application, while retaining the earlier priority date.
According to the information provided on the patent's front page, US7793332B1 is a continuation-in-part of application numbers US06/317,510 (now US4694490A) and US08/113,239 (now US5444365A). A continuation-in-part application repeats a substantial portion of the parent's specification but allows for the addition of new material.

Divisional Applications

A divisional patent application presents claims that were originally filed in the parent application but were required by the USPTO to be withdrawn or canceled because the examiner found more than one invention in the initial application.
The provided information does not explicitly list any divisional applications for US Patent 7793332.

Related Family Members

The patent explicitly claims priority from:

• US06/317,510, filed 1981-11-03 (issued as US4694490A)
• US08/113,239, filed 1993-08-30 (issued as US5444365A)

Therefore, its related family members, based on priority claims, include US4694490A and US5444365A.

Projected Expiration Date

For U.S. utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the earliest filing date of the application, or if the application claims priority to an earlier filed application under 35 U.S.C. §§ 120, 121, or 365(c), 20 years from the filing date of the earliest such application.

US Patent 7793332 has a filing date of June 7, 1995. However, it claims priority from:

• US06/317,510, with a filing date of November 3, 1981.

Therefore, the patent term is calculated from the earliest priority date, which is November 3, 1981.
20 years from November 3, 1981, is November 3, 2001.

However, the provided patent information states an "Anticipated expiration" date of September 7, 2027. This suggests that the patent's effective term is not simply 20 years from the earliest priority date and that it may be subject to a terminal disclaimer or other specific circumstances that modify the standard calculation. Without access to the full prosecution history to determine any terminal disclaimers or specific legal interpretations made during prosecution, it is difficult to reconcile the disparity.

Assuming the "Anticipated expiration" date listed on the patent (September 7, 2027) is accurate as per USPTO records, this would be the projected expiration date.
