Extensions

To detail the requested information for US patent 8668592, I will use the authoritative data from the USPTO and other reliable patent resources.

Patent Term Adjustment (PTA)

Patent Term Adjustment (PTA) is granted to compensate for delays caused by the USPTO during the prosecution of a patent application. It adds additional time to the 20-year lifespan of a utility or plant patent. This adjustment is calculated at the time the patent issues and is included in the Issue Notification Letter.

For US patent 8668592, the Google Patents entry indicates an "Adjusted expiration" date of March 12, 2032. Given that the original filing date was December 14, 2011, and the patent issued on March 11, 2014, a standard 20-year term from the filing date would typically lead to an expiration date of December 14, 2031. The reported expiration date of March 12, 2032, suggests that approximately 3 months of PTA were awarded. This adjustment would compensate for delays in the patent's issuance beyond certain statutory deadlines, such as failing to issue within three years of the actual filing date.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products. These extensions aim to restore some of the patent term lost while awaiting premarket government approval from regulatory agencies like the FDA.

US patent 8668592 pertains to "Systems and methods of changing storyline based on player location," which falls within the domain of video games and virtual environments, not pharmaceuticals, medical devices, or other products requiring regulatory approval. Therefore, it is highly unlikely that this patent would be eligible for a Patent Term Extension under 35 U.S.C. § 156.

Continuation Applications, Divisional Applications, and Related Family Members

The patent states that it claims priority from U.S. Provisional Application No. 61/459,630, filed on December 17, 2010. This provisional application is a related family member. The patent itself, US8668592B2, is the granted patent from application US13/325,151. [cite: 027003/0861]

The Google Patents "Priority Applications" section lists:

• US13/325,151 (which is the application that led to US8668592B2) [cite: 027003/0861]
• US201061459630P (the provisional application) [cite: 027003/0861]

The "Applications Claiming Priority" section lists:

• US201061459630P (the provisional application) [cite: 027003/0861]
• US13/325,151 [cite: 027003/0861]

The "Publications" section lists:

• US20120157197A1 (a patent application publication) [cite: 027003/0861]
• US8668592B2 (the granted patent) [cite: 027003/0861]

The "Family Applications" section lists:

• US13/325,151 (which resulted in US8668592B2) [cite: 027003/0861]

Based on this, US20120157197A1 is the application publication for the same application that matured into US8668592. The provisional application US61/459,630 is the earliest priority document. There are no other continuation or divisional applications explicitly listed in the patent's front page or in the provided family data.

Projected Expiration Date

The legal status information on Google Patents explicitly states "Active, expires 2032-03-12." This date already incorporates any Patent Term Adjustment (PTA) that may have been granted. Utility patents generally expire 20 years from their earliest filing date, with potential adjustments for USPTO delays. The filing date for application US13/325,151 was December 14, 2011, and it claims priority to a provisional application filed on December 17, 2010. [cite: 027003/0861] Therefore, the 20-year term would typically be calculated from the priority date of December 17, 2010, placing the unadjusted expiration on December 17, 2030. However, the "Adjusted expiration" of March 12, 2032, indicates that Patent Term Adjustment has extended the patent's life. [cite: 027003/0861]

Projected Expiration Date: March 12, 2032. [cite: 027003/0861]
