Extensions

To provide comprehensive details on US patent 11014301 regarding patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and its projected expiration date, direct access to the USPTO Public Patent Search database for this specific patent number is needed. While I cannot directly access real-time USPTO databases, I can provide general information about these concepts and guide you on where to find this information once you access the USPTO system.

Based on the information available and general patent law:

1. 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 the patent application process. These delays include:

• Failure to issue a first Office Action within 14 months of filing.
• Failure to respond to an applicant's reply within four months.
• Failure to issue a patent within three years of the actual filing date (with certain provisos).
• Failure to issue the patent within four months of payment of the issue fee.

The total PTA is added to the standard 20-year term of the patent. Applicant delays can reduce any awarded PTA. The official PTA calculation is included in the Issue Notification Letter mailed to applicants before the patent issues. To determine the specific PTA for US patent 11014301, you would need to consult the patent's file history on the USPTO Patent Center or Patent Public Search.

2. Patent Term Extensions (PTE)
Patent Term Extension (PTE) is available for patents claiming products, methods of use, or manufacturing processes that require regulatory approval (e.g., from the FDA) before commercial marketing. This extension aims to restore a portion of the patent term lost during this regulatory review period. PTE cannot exceed five years and cannot extend the patent term beyond 14 years from the date of marketing approval.
Given that US patent 11014301 relates to additive manufacturing systems, it is unlikely to be eligible for PTE, as PTE typically applies to specific regulated products like human drugs, medical devices, food additives, or color additives. To confirm, you would look for any PTE applications or certificates within the patent's file history on the USPTO website.

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

• Continuation Application: A continuation application discloses the same invention as a prior-filed, copending nonprovisional application, without introducing new subject matter. The patent text for US11014301 states that it is a continuation of U.S. patent application Ser. No. 16/370,337, filed Mar. 29, 2019. This means that US11014301 is a continuation of application 16/370,337.
• Divisional Application: A divisional application is filed when an examiner determines that an original application contains more than one patentable invention. The applicant can then file a divisional application to pursue the invention not elected in the parent application.
• Related Family Members: These include patents and applications that share a common priority claim. The patent itself mentions priority to U.S. Provisional Patent Application No. 62/711,719, filed on Jul. 30, 2018, and U.S. Provisional Patent Application No. 62/734,003, filed on Sep. 20, 2018. The "Other versions" section of the Google Patents page also lists US20200353685A1. The "Priority date" section indicates further priorities to US17/301,204 (filed 2021-03-29), US17/661,856 (filed 2022-05-03), US17/815,398 (filed 2022-07-27), US18/390,403 (filed 2023-12-20), US19/207,025 (filed 2025-05-13), and US19/248,250 (filed 2025-06-24), indicating a complex patent family. To see the complete family tree, you would need to search the USPTO Patent Center or Espacenet.

4. Projected Expiration Date
A U.S. utility patent filed on or after June 8, 1995, generally expires 20 years from its earliest effective filing date, including any priority claims to earlier non-provisional applications. This 20-year term can be adjusted by PTA or PTE. Maintenance fees must also be paid at 3.5, 7.5, and 11.5 years after the grant date to keep the patent in force.

For US patent 11014301:

• The application filing date is July 24, 2020.
• The patent also claims priority to U.S. Provisional Patent Application No. 62/711,719, filed on July 30, 2018. This is the earliest priority date.
• Therefore, the base patent term would be 20 years from July 30, 2018, which is July 30, 2038.
• The Google Patents "Anticipated expiration" date is listed as 2039-03-29. This suggests that there is a Patent Term Adjustment (PTA) of approximately 8 months and 29 days (March 29, 2039 - July 30, 2038).

To definitively confirm the PTA and the precise expiration date, you would need to access the official USPTO Patent Center record for patent 11014301 and review the "Patent Term Adjustment" section, which is typically found in the Issue Notification. The USPTO does not calculate expiration dates for patents publicly, but provides a calculator and guidelines to help estimate it, taking into account PTA, PTE, and terminal disclaimers.
