Extensions

The USPTO does not calculate patent expiration dates directly, but provides tools and guidance for doing so. The term of a U.S. utility patent filed on or after June 8, 1995, generally expires 20 years from its earliest filing date, with potential adjustments or extensions.

For US Patent 7055169:

• Patent Number: 7055169
• Filing Date: April 21, 2003 [cite: Filing date]
• Issue Date: May 30, 2006 [cite: Publication date]
• Priority Date: April 19, 2002 [cite: Priority date (The priority date is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)]

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can extend the term of a U.S. patent to compensate for delays caused by the USPTO during prosecution. It applies to applications filed on or after May 29, 2000. Delays covered by PTA include:

• Failure to issue a first Office Action or notice of allowance within 14 months of filing.
• Failure to issue an action within four months of an applicant's response to an Office Action.
• Failure to issue the patent within four months of payment of the issue fee.
• Failure to issue a patent within three years of the actual filing date of the application.

The total PTA can be reduced by delays caused by the applicant.

The provided patent text and the Google Patents record indicate an "Adjusted expiration" date of September 28, 2023 [cite: Legal status (The legal status is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.), Adjusted expiration]. This "Adjusted expiration" date implies that some Patent Term Adjustment (PTA) was applied to the patent, extending its term beyond the typical 20 years from the earliest filing date. Without access to the specific Issue Notification Letter or the official USPTO patent file wrapper for US7055169, the exact calculation of this PTA cannot be determined from the provided information.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) under 35 U.S.C. § 156 are typically available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products, to compensate for time lost during regulatory review by agencies like the FDA. Given the subject matter of US7055169 (interactive television functionality), it is highly unlikely to have received a Patent Term Extension under 35 U.S.C. § 156, as it does not relate to these regulated product categories. The provided patent information does not indicate any PTE was granted.

Continuation Applications and Divisional Applications

• Continuation applications are follow-up applications that are essentially duplicates of an earlier "parent" application, inheriting its priority date and subject matter coverage.
• Divisional applications are filed when an earlier application is deemed to contain more than one invention. The divisional application covers the invention(s) not elected for prosecution in the original (parent) application. Like continuations, they benefit from the priority date of the original application.

The Google Patents record for US7055169 lists an application number US10/419,621 and indicates "Other versions: US20040139480A1". The application number US10/419,621 corresponds to the filing of US7055169B2. US20040139480A1 is the publication of the application for US7055169.
The provided information does not explicitly state that US7055169 itself is a continuation or divisional application of an earlier non-provisional application, other than claiming priority to provisional application No. 60/373,883, filed on April 19, 2002 [cite: Priority of provisional application No. 60/373,883, filed on Apr. 19, 2002 is claimed under 35 U.S.C. §§ 119(a)–(e)]. Provisional applications do not factor into the 20-year patent term calculation in the same way as non-provisional applications. The 20-year term is typically calculated from the filing date of the earliest non-provisional application to which priority is claimed. Since the patent claims priority to a provisional application and not an earlier non-provisional application for the purpose of the 20-year term calculation, the effective filing date for term calculation purposes is generally the filing date of the application itself (April 21, 2003).

Related Family Members

The provided Google Patents data lists:

• US7055169B2 (granted patent)
• US10/419,621 (application number for US7055169B2)
• US41962103A (another format of the application number)
• US20040139480A1 (publication of the application)

Additionally, the patent claims priority to U.S. Provisional Patent Application No. 60/373,883, filed April 19, 2002 [cite: Priority of provisional application No. 60/373,883, filed on Apr. 19, 2002 is claimed under 35 U.S.C. §§ 119(a)–(e)]. This provisional application is a related family member, establishing the earliest priority date.

Projected Expiration Date

The "Legal status" section of the Google Patents record explicitly states "Expired - Lifetime" and "adjusted expiration, expires 2023-09-28" [cite: Legal status (The legal status is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.)].

Based on the original filing date of April 21, 2003, a standard 20-year term would have resulted in an expiration date of April 21, 2023. However, the patent's "Adjusted expiration" is September 28, 2023 [cite: Legal status (The legal status is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the list.)], which is approximately 5 months and 7 days after the standard 20-year term from the filing date. This indicates that Patent Term Adjustment (PTA) was applied to extend the patent's life due to USPTO delays during prosecution.

Therefore, the projected expiration date was September 28, 2023. Since today's date is May 21, 2026, the patent has already expired.
