Extensions

To provide a detailed analysis of US patent 10379539, I will first clarify the different types of patent term adjustments and extensions, and then apply that understanding to the patent's specific information.

Patent Term Adjustment (PTA)
PTA compensates patent owners for delays caused by the USPTO during the examination process of a utility or plant patent application. This adjustment adds time to the standard 20-year patent term from the earliest filing date. Delays can include the USPTO failing to: issue a first office action within 14 months, respond to applicant replies within four months, or issue the patent within three years of the filing date or four months of the issue fee payment.

Patent Term Extension (PTE)
PTE, established under the Hatch-Waxman Act, is available for patents claiming products (e.g., human drugs, medical devices, food additives, or color additives) that have undergone lengthy pre-market regulatory review by agencies like the FDA. The extension aims to restore some of the patent term lost during this review process, with a maximum extension of five years. Generally, only one patent can be extended per regulatory review period, and the total patent life with PTE cannot exceed 14 years from the date of FDA approval.

Continuity Data (Continuations and Divisionals)
A patent can claim priority to an earlier-filed application (the "parent") through continuation, divisional, or continuation-in-part applications.

• Continuation Application: Filed during the pendency of a parent application, claiming the same invention.
• Divisional Application: Filed in response to a USPTO restriction requirement, claiming a distinct invention disclosed but not claimed in the parent application.
• Continuation-in-Part (CIP) Application: Includes new matter in addition to claiming priority to a parent application.

The term of a patent granted on a continuation, divisional, or CIP application filed after June 8, 1995, expires 20 years from the filing date of the earliest application for which a benefit is claimed.

Analysis of US Patent 10379539

Patent Term Adjustments (PTA):
The provided information does not explicitly state the amount of Patent Term Adjustment (PTA) granted for US10379539. PTA calculations are typically determined by the USPTO at the time of patent issuance and are included in the Issue Notification Letter. To determine the exact PTA, one would need to access the patent's prosecution history in USPTO's Patent Center (PAIR).

Patent Term Extensions (PTE):
Based on the nature of the invention, "Systems and methods for dynamic route planning in autonomous navigation" for robots (including floor cleaners), it is highly unlikely that US10379539 would be eligible for Patent Term Extension (PTE). PTE is typically granted for patents related to drug products, medical devices, food additives, or color additives that undergo a regulatory review process by agencies like the FDA or Department of Agriculture. There is no indication in the patent text or search results that the claimed invention falls under these categories.

Continuation and Divisional Applications:

US10379539 is explicitly identified as a continuation of U.S. patent application Ser. No. 15/341,612, which issued as U.S. Pat. No. 10,001,780.

• Parent Application: U.S. Pat. No. 10,001,780 (Application Ser. No. 15/341,612).
• Filing Date of Parent Application: November 2, 2016.

The Google Patents information for US10379539 also notes a "Priority to US16/454,217" on June 27, 2019, which published as US20200004253A1. This indicates that US16/454,217 is likely a child application (e.g., a continuation or divisional) of US10379539 or its parent, forming part of the same patent family.

Related Family Members:

• US10001780B2: Parent patent (U.S. patent application Ser. No. 15/341,612), with a filing date of November 2, 2016.
• US20180364724A1: This is another version of the application that led to US10379539, published on December 20, 2018.
• US20200004253A1: A related application (US16/454,217) with a priority date of June 27, 2019.

Projected Expiration Date:

The standard term for U.S. utility patents issued from applications filed on or after June 8, 1995, is 20 years from the earliest effective filing date, subject to any Patent Term Adjustments.

For US10379539, the earliest priority date is November 2, 2016, from its parent application U.S. patent application Ser. No. 15/341,612 (U.S. Pat. No. 10,001,780).

Therefore, without considering any PTA, the projected expiration date would be 20 years from November 2, 2016.

• Base Expiration Date: November 2, 2016 + 20 years = November 2, 2036.

The Google Patents information corroborates this, listing "2036-11-02" as the "Anticipated expiration" date.

Summary of Expiration Date and Adjustments:

• Filing Date of US10379539: June 18, 2018.
• Earliest Priority Date (from parent US10001780): November 2, 2016.
• Standard 20-Year Term from Earliest Priority Date: November 2, 2036.
• Patent Term Adjustment (PTA): The amount of PTA is not explicitly stated in the provided information but would be added to the 20-year term to compensate for USPTO delays.
• Patent Term Extension (PTE): Not applicable for this patent.
• Projected Expiration Date (without PTA): November 2, 2036.

To obtain the precise expiration date, including any PTA, the official documentation from the USPTO's Patent Center (PAIR) would need to be consulted.
