Extensions

To detail the patent term adjustments (PTA), patent term extensions (PTE), continuation applications, divisional applications, related family members, and projected expiration date for US Patent 8989441, I will rely on information available through the USPTO.

Patent Term Adjustments (PTA):
Patent Term Adjustment (PTA) is granted to compensate for certain delays by the USPTO during the prosecution of a patent application. This can include delays such as failing to issue an office action within 14 months of filing, responding to a reply within four months, or issuing a patent within three years of the actual filing date. The specific PTA for US8989441 is not directly stated in the provided text snippets, but Google Patents indicates an "Adjusted expiration" date of 2033-08-17, which implies PTA was applied.

Patent Term Extensions (PTE):
Patent Term Extension (PTE) is available under the Hatch-Waxman Act for patents claiming products that require regulatory approval (e.g., human drugs, medical devices) to restore patent term lost during the regulatory review process. There is no indication that US8989441, which relates to motion recognition, is subject to regulatory review under the Hatch-Waxman Act. Therefore, it is highly unlikely to have received a PTE.

Continuation and Divisional Applications:
A continuation application allows an applicant to pursue claims based on the same specification and drawings as a pending "parent" application, sharing the same priority date. A divisional application presents claims that were originally filed with the parent application but were required to be withdrawn or canceled by the USPTO.

US8989441 (Application number US13/846,700) is noted to be a member of a patent family. The Google Patents "Family Applications" section lists:

• US13/846,700 (which led to US8989441B2).
• CN201310049750.3A (Chinese application). [cite: CN103076884B]
• CN201310049750 (Chinese application). [cite: CN103076884B]
• CN103076884B (Chinese patent). [cite: CN103076884B]

The patent itself claims priority from Chinese Patent Application No. 201310049750.3, filed on February 7, 2013. [cite: US8989441B2] This indicates that US8989441 is not a continuation or divisional of another U.S. patent application, but rather claims priority to an earlier foreign application. The provided data does not explicitly mention any continuation or divisional U.S. applications stemming directly from US13/846,700.

Related Family Members:
The patent family includes:

• US8989441B2 (the granted U.S. patent)
• US20140219498A1 (a U.S. patent application publication, an earlier publication of the same U.S. application).
• CN201310049750.3 (Chinese priority application). [cite: US8989441B2]
• CN103076884B (Chinese patent granted from the priority application). [cite: CN103076884B]
• WO2014121566A1 (a PCT international application).

Projected Expiration Date:
For utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the date of the earliest non-provisional application in its chain of priority, plus any Patent Term Adjustment (PTA).

• Filing Date (US Application): March 18, 2013 [cite: US8989441B2]
• Priority Date (Chinese Application): February 7, 2013 [cite: US8989441B2]

The base term would be 20 years from the earliest priority date, which is February 7, 2013. This would set a base expiration date of February 7, 2033.

Google Patents states an "Adjusted expiration" date of 2033-08-17. This indicates that Patent Term Adjustment (PTA) was granted for delays during prosecution, extending the patent term from the base 20 years (from the priority date) by approximately 6 months and 10 days. [cite: US8989441B2]
