Extensions

US Patent 9928864, titled "Multilayer exchange spring recording media," was granted on March 27, 2018, from an application filed on November 17, 2009.

Here's a breakdown of its term adjustments, extensions, and family relationships:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) extends the term of a U.S. patent to compensate for delays caused by the USPTO during the prosecution of a utility or plant patent application. The USPTO's automated system calculates PTA at the time the patent is issued.
The provided patent text and search results do not explicitly state the specific number of days of Patent Term Adjustment (PTA) granted for US9928864. To determine the exact PTA, one would typically need to review the Issue Notification Letter or the patent's electronic file wrapper in Patent Center.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available for patents that claim certain human drug products, medical devices, animal drugs, and food or color additives to restore time lost during premarket government approval from a regulatory agency like the FDA.
There is no indication in the provided patent text or search results that US9928864 is eligible for or has received any Patent Term Extension (PTE), as it relates to magnetic recording media, not FDA-regulated products.

Continuation and Divisional Applications

• Continuation Applications: A continuation application is filed for an invention disclosed in a prior, copending nonprovisional application, without introducing new subject matter.
• Divisional Applications: A divisional application is filed when an earlier application is deemed to contain more than one invention.
  The patent text indicates the following related applications:
  • Priority Applications: US9928864B2 claims priority to US12/619,849 (itself). It also lists US15/925,749 and US17/492,735 as priority applications.
  • Applications Claiming Priority: US9928864B2 is listed as claiming priority to US12/619,849. Additionally, US9978413B2 (US11/424,859) claims priority to the same underlying priority date.
  • Related Parent Applications: US11/424,859 (US9978413B2) is identified as a "Division" of the family, sharing the same priority date.
  • Related Child Applications: US15/925,749 (US11138997B2) is identified as a "Continuation" of the family, sharing the same priority date.

This indicates that US9928864 is part of a family of patents, including both divisional and continuation applications stemming from the same initial priority date of 2006-06-17.

Related Family Members

The patent family includes several related applications, all sharing the priority date of June 17, 2006:

• US9978413B2 (Application US11/424,859, filed 2006-06-17, "Division")
• US9928864B2 (Application US12/619,849, filed 2009-11-17)

• US11133031B2 (Application US15/985,661, filed 2018-05-21)
• US11908500B2 (Application US17/486,608, filed 2021-09-27)
• US12020734B2 (Application US17/492,735, filed 2021-10-04)
• US20240079030A1 (Application US18/503,873, filed 2023-11-07, "Abandoned")

Projected Expiration Date

The legal status for US9928864B2 is "Active," and it has an "Adjusted expiration" date of 2027-06-30.
The term of a U.S. patent is generally 20 years from the earliest-claimed non-provisional filing date. Since the priority date for this patent family is June 17, 2006, the original 20-year term would typically end around June 17, 2026. However, the listed "Adjusted expiration" date of June 30, 2027, suggests that Patent Term Adjustment (PTA) has been applied to extend the patent term beyond the standard 20 years from its earliest priority date.
