Extensions

To provide a comprehensive analysis of US patent 10541279 regarding patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and projected expiration date, I will rely on information from the Google Patents page for US10541279 and general USPTO rules on patent term.

Here's the breakdown for US Patent 10541279:

Patent Term Adjustment (PTA)

Patent Term Adjustment (PTA) compensates patentees for delays caused by the USPTO during prosecution. It extends the patent term beyond the standard 20 years from the earliest non-provisional filing date. These delays can include the USPTO failing to: issue a first office action within 14 months of filing, respond to an applicant's reply within four months, or issue the patent within 36 months of filing.

The Google Patents page for US10541279 states the patent "expires 2037-09-14."

• Original Filing Date: July 26, 2017.
• Publication Date: January 21, 2020.
• Statutory 20-year term from filing date: July 26, 2037.

Since the "expires" date (September 14, 2037) is later than the statutory 20-year term from the filing date (July 26, 2037), this indicates that Patent Term Adjustment (PTA) was granted for US10541279. The difference in days, approximately 49 days (from July 26, 2037, to September 14, 2037), represents the PTA awarded due to USPTO administrative delays during prosecution. The exact calculation is typically provided by the USPTO in the Issue Notification Letter.

Patent Term Extension (PTE)

Patent Term Extension (PTE) is available for patents claiming products (e.g., human drugs, medical devices, food or color additives, animal drugs) that require regulatory approval before commercial marketing. PTE aims to restore patent term lost during the regulatory review process.

There is no indication on the Google Patents page for US10541279, nor is it typically found on a patent's front page, that Patent Term Extension (PTE) has been applied for or granted. Given the nature of the invention ("Display device") which does not appear to relate to products requiring premarket government approval (e.g., FDA approval), it is highly unlikely that this patent would be eligible for PTE.

Continuation and Divisional Applications, and Related Family Members

• Application Number: US15/660,827 (This is the application number for US10541279 itself).
• Priority Date: July 29, 2016.

The Google Patents page explicitly lists the following "Other versions" and "Priority to" information, which indicates related family members and potential continuation/divisional applications:

• US20180033833A1: This is the publication of the application that resulted in US10541279B2. This is not a separate family member in the sense of a continuation or divisional, but rather the initial publication of the application.
• Priority to US16/742,230: This indicates that application US16/742,230 claims priority to US10541279. This would typically be a continuation or divisional application if it was filed during the pendency of the US10541279 application.
  • Patent/Publication associated with US16/742,230: US11500496B2.
• Priority to US18/055,275: This indicates that application US18/055,275 claims priority to US10541279 (or an application in its chain).
  • Patent/Publication associated with US18/055,275: US11861117B2.
• Priority to US18/400,641: This indicates that application US18/400,641 claims priority to US10541279 (or an application in its chain).
  • Patent/Publication associated with US18/400,641: US20240231545A9.

These "Priority to" entries suggest that US10541279 is a parent application for subsequent continuation or divisional applications (US16/742,230, US18/055,275, US18/400,641). A continuation application is for an invention disclosed in a prior-filed copending application with no new matter, while a divisional application arises from a restriction requirement where multiple distinct inventions were claimed in the parent application. Without examining the prosecution history of each, it's not possible to definitively classify them as continuations or divisionals, but they are clearly related family members.

Projected Expiration Date

• Filing Date of US10541279 (US15/660,827): July 26, 2017.
• Earliest Priority Date (Korean Patent Application No. 10-2016-0097493): July 29, 2016.
• Statutory Term (20 years from earliest filing date): July 29, 2036 (20 years from the priority date, as the US application claims benefit of the Korean priority date).

However, the Google Patents page states the legal status as "Active, expires 2037-09-14." This "Adjusted expiration" date reflects the addition of Patent Term Adjustment (PTA).

Therefore, the projected expiration date for US Patent 10541279 is September 14, 2037. This date already accounts for any Patent Term Adjustment granted by the USPTO.
