Extensions

For US patent 11143120, here's a detailed breakdown of its term adjustments, related applications, and projected expiration:

1. Patent Term Adjustment (PTA):
The provided patent information for US11143120 does not explicitly state any Patent Term Adjustment (PTA) in days. However, PTA is a system that adds time to a patent's 20-year term to compensate for certain delays by the USPTO during prosecution. These delays can include:

• Failure to issue a first Office Action or notice of allowance within 14 months of filing.
• Failure to act 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 (excluding applicant-caused delays).

PTA is calculated at the time the patent issues and is included in the Issue Notification Letter.

2. Patent Term Extension (PTE):
There is no indication that US11143120 has received or is eligible for Patent Term Extension (PTE). PTE is a statutory remedy primarily available for patents covering human or veterinary drugs, medical devices, food additives, or color additives, to compensate for time lost during pre-market regulatory review by agencies like the FDA. This patent, relating to a fuel system for an internal combustion engine, does not fall into these categories. The maximum PTE is 5 years, and the total post-approval patent life cannot exceed 14 years from the date of FDA approval.

3. Continuation Applications:
US11143120 is explicitly identified as a continuation of and claims priority to several earlier patent applications:

• U.S. patent application Ser. No. 16/358,822, filed Mar. 20, 2019 (which issued as US10697379B2).
• U.S. patent application Ser. No. 15/285,215, filed Oct. 4, 2016 (which issued as U.S. Pat. No. 10,393,034).
• U.S. patent application Ser. No. 14/925,441, filed Oct. 28, 2015 (which issued as US10697398B2).
• U.S. patent application Ser. No. 14/738,060, filed Jun. 12, 2015 (which issued as U.S. Pat. No. 10,221,780).

The term "continuation" implies that these earlier applications share a common disclosure with US11143120, but present different claims.

4. Divisional Applications:
The patent document does not explicitly state that US11143120 is a divisional application. However, divisional applications arise when a single patent application contains more than one patentable invention, and the applicant chooses to pursue the non-elected inventions in a separate, later-filed application.

5. Related Family Members:
Based on the continuation chain, the following are related family members:

• US10697379B2 (from application Ser. No. 16/358,822)
• US10393034B2 (from application Ser. No. 15/285,215)
• US10697398B2 (from application Ser. No. 14/925,441)
• US10221780B2 (from application Ser. No. 14/738,060)

The Google Patents page also lists "Family Applications (3)" with the same priority date of 2015-06-12, reinforcing these as related family members.

6. Projected Expiration Date:
The Google Patents page explicitly states the "Anticipated expiration" date for US11143120 as 2035-06-12.

For utility patents, the patent term is generally 20 years from the earliest filing date (or priority date) of the non-provisional application. In this case, the earliest priority date claimed is June 12, 2015, from U.S. patent application Ser. No. 14/738,060. Therefore, 20 years from this date would be June 12, 2035, aligning with the "Anticipated expiration" date provided by Google Patents. This date would be subject to any PTA or PTE, but as noted, no PTE is expected, and any PTA would need to be calculated based on the prosecution history.
