Extensions

For US patent 8891347, here's a breakdown of its term adjustments, related applications, and projected expiration:

Patent Term Adjustments (PTA) and Extensions (PTE):

• Patent Term Adjustment (PTA): The Google Patents entry for US8891347 indicates "Adjusted expiration 2032-01-22". This suggests that Patent Term Adjustment (PTA) has been applied to the patent. PTA is granted to compensate for delays caused by the USPTO during the prosecution of a utility or plant patent application. This adjustment adds days to the standard 20-year patent term.
• Patent Term Extension (PTE): There is no indication in the Google Patents data or the provided text of a Patent Term Extension (PTE) for US8891347. PTE is typically available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost during premarket government approval from a regulatory agency.

Continuation and Divisional Applications:

• The Google Patents page for US8891347 lists "Other versions" including US20130107733A1. This is a patent application publication, and for utility patents filed on or after June 8, 1995, the patent term is 20 years from the filing date of the earliest U.S. non-provisional or PCT application to which priority is claimed. While not explicitly stated as a continuation or divisional in the provided text, patent family information often links such applications. Without further direct search of the USPTO's Patent Center (formerly Public PAIR), it cannot be definitively confirmed if US20130107733A1 is a continuation or divisional of the application that matured into US8891347.

Related Family Members:

• The primary related family member explicitly mentioned is US20130107733A1, which is the publication of the application that led to US8891347B2. The patent abstract also references "PCT/CN2011/077718" in its "OTHER PUBLICATIONS" section, indicating an international application from which priority might be claimed.

Projected Expiration Date:

• The Google Patents entry for US8891347 explicitly states "Active, expires 2032-01-22". This "Adjusted expiration" date reflects the original 20-year term from the earliest priority date, plus any Patent Term Adjustment (PTA) awarded. The filing date of US8891347 was July 28, 2011. A standard 20-year term from this date would be July 28, 2031. The reported adjusted expiration date of January 22, 2032, suggests a PTA of approximately 5 months and 25 days.
