Extensions

To detail the requested information for US Patent 9253428, I will rely on information typically found in the USPTO Public Patent Application Information Retrieval (PAIR) system or equivalent patent databases that provide a comprehensive record of a patent's prosecution history and status. Based on the current general information available and common patent practices:

US Patent 9253428: Term and Application Details

• Filing Date: 2015-05-20
• Issue Date: 2016-02-02
• Application Number: US14/717,220

1. Patent Term Adjustments (PTA):
Patent Term Adjustments (PTA) compensate patent applicants for certain delays caused by the USPTO during the prosecution of a utility or plant patent application. The total PTA is added to the standard 20-year lifespan of the patent. Common delays include the USPTO failing to: issue an office action within 14 months of filing; respond to an applicant's reply or appeal within four months; act on an application within four months after a PTAB or federal court decision; issue a patent within four months after issue fee payment; or issue a patent within 36 months from the filing date.

To determine the exact PTA for US9253428, one would typically examine the "Issue Notification" or "Patent" document available through the USPTO's Patent Center (formerly PAIR) system. Without direct access to this specific document, the exact PTA for this patent cannot be definitively stated here. However, based on the filing and issue dates:

• Application Filing to Issue within 36 Months: The application was filed on May 20, 2015, and issued on February 2, 2016. This is approximately 8.5 months, well within the 36-month timeframe for "B" delays (delay from filing to issue) as defined by 35 U.S.C. § 154(b) and 37 CFR 1.702(b) & 1.703(b).
• Other Potential Delays: Delays can also accrue from the USPTO failing to issue a first office action within 14 months or respond to amendments within 4 months. A detailed analysis of the patent's prosecution history would be required to identify any such "A" or "C" delays and any applicant-caused delays that might offset PTA.

2. Patent Term Extensions (PTE):
Patent Term Extensions (PTE) are available under 35 U.S.C. § 156, primarily for patents claiming products (human drugs, food/color additives, medical devices, animal drugs, and veterinary biological products) that require lengthy premarket government approval from a regulatory agency like the FDA. PTE aims to restore a portion of the patent term lost during this regulatory review process. The patent's subject matter relates to "Broadcasting system with digital television signals and metadata," which does not fall into the categories eligible for PTE. Therefore, it is highly unlikely that US9253428 has received any Patent Term Extension.

3. Continuation Applications, Divisional Applications, and Related Family Members:

• Continuation Applications: A continuation application is a new application for an invention disclosed in a prior, co-pending non-provisional application, where the disclosure does not include any new matter. Its purpose is to allow for further examination of claims.
• Divisional Applications: A divisional application is filed when an earlier application claimed two or more independent and distinct inventions, and the USPTO required restriction.
• Related Family Members: These include parent applications, continuations, divisionals, continuations-in-part, and foreign equivalents.

The provided patent information lists "US20150341586A1" under "Other versions." This is a patent application publication, indicating it is the published application for US9253428. The current application number is US14/717,220, which has a priority date of 2014-05-21 and a filing date of 2015-05-20.

To definitively identify any continuation or divisional applications, or other related family members beyond the immediate application publication, a search of the USPTO's public database (Patent Center) for the application family history of US14/717,220 would be necessary. Without this specific search, I cannot confirm if any such related applications exist.

4. Projected Expiration Date:
The basic patent term for a U.S. patent filed on or after June 8, 1995, is 20 years from its earliest effective filing date. The filing date for US9253428 is May 20, 2015.

Therefore, the unadjusted expiration date would be May 20, 2035.

Considering the potential for Patent Term Adjustment (PTA):
As noted above, the time from filing to issue (May 20, 2015, to February 2, 2016) was less than 36 months, which usually minimizes or eliminates "B" delays. Without the specific PTA calculation from the USPTO, the definitive expiration date cannot be precisely stated. However, given the relatively quick prosecution, it is likely that any PTA awarded would be minimal, if any.

Based on the information available:

• Anticipated Expiration (unadjusted): May 20, 2035.
• Adjusted Expiration: The "Info" section of the Google Patents record for US9253428 B2 states "Anticipated expiration 2035-05-20." This indicates that, as of the Google Patents record, no significant PTA was applied or that the 20-year term from the filing date is the prevailing expiration.

Therefore, the projected expiration date for US Patent 9253428 is May 20, 2035. This date would only be modified by any awarded PTA (which appears to be zero based on the Google Patents information) or by a terminal disclaimer, which is not indicated here.
