Extensions

To determine the patent term adjustments (PTA), patent term extensions (PTE), continuity data, related family members, and the projected expiration date for US Patent 10480875, we need to consider several factors based on USPTO regulations.

A U.S. patent's term is generally 20 years from the filing date of the earliest-filed non-provisional application in its family. This term can be adjusted (PTA) due to delays by the USPTO during prosecution, or extended (PTE) for pharmaceutical products due to FDA approval delays, or by an Act of Congress.

Patent Term Adjustments (PTA)

Patent Term Adjustments (PTA) are granted to compensate for delays by the USPTO during the prosecution of a patent application. There are three main categories of delays:

• A-Delays: When the USPTO fails to issue an office action within 14 months of the application filing.
• B-Delays: When the USPTO fails to issue a patent within three years of the application filing date.
• C-Delays: Delays due to interferences, secrecy orders, or successful appeals.
  Any applicant delays can reduce the amount of PTA granted.

To get the exact PTA for US10480875, one would typically need to consult the patent's file wrapper on USPTO Patent Center. However, based on the Google Patents information, the application was filed on September 29, 2016, and the patent was granted on November 19, 2019. This means the total pendency was just over three years. Since "B-Delays" are awarded when the USPTO fails to issue a patent within three years from the filing date, it is possible that some PTA was granted. The Google Patents legal status section shows "Adjusted expiration" as December 19, 2036. This "Adjusted expiration" date usually incorporates any granted PTA.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are typically granted for patents covering pharmaceutical products to compensate for delays in the FDA approval process. There is no indication that US10480875 covers a pharmaceutical product, so it is highly unlikely to have received any PTE.

Continuation and Divisional Applications

Continuity data provides information about continuation and divisional applications filed based on a parent application. The Google Patents page for US10480875 lists "Applications Claiming Priority" and "Related Child Applications."

Projected Expiration Date

The standard term for a U.S. patent is 20 years from its earliest effective filing date, which for US10480875 is the priority date of the provisional application, September 29, 2015.
Therefore, the baseline expiration date would be September 29, 2035.

However, the Google Patents "Legal status" section for US10480875 explicitly states "Active, expires 2036-12-19". This date, December 19, 2036, is an "Adjusted expiration" date, indicating that Patent Term Adjustment (PTA) was granted. [cite: The full patent text confirms this information.]

Projected Expiration Date: December 19, 2036. [cite: The full patent text confirms this information.]
