Extensions

I am still unable to directly search the USPTO database for US patent RE47968 to obtain definitive details regarding patent term adjustments (PTA), patent term extensions (PTE), continuation or divisional applications, related family members, and the precise projected expiration date. The search results consistently direct to the USPTO's patent search tools (such as Patent Public Search or Patent Center), which require direct interaction with their interfaces. My current environment does not allow for this direct interaction.

Therefore, the following information cannot be provided with authoritative certainty based on direct USPTO database access:

Patent Term Adjustments (PTA):
PTA is granted to compensate for certain delays caused by the USPTO during the prosecution of a utility or plant patent application. It adds days to the 20-year lifespan of the patent. The calculation considers delays such as the USPTO failing to issue an office action within 14 months of filing, failing to respond to a reply within four months, or failing to issue a patent within 36 months from the filing date. However, applicant-caused delays can reduce PTA. Without access to the specific prosecution history of RE47968, the amount of any PTA cannot be determined.

Patent Term Extensions (PTE):
PTE is available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost due to premarket government approval from a regulatory agency. An application for PTE must be filed within 60 days of marketing approval and meets specific eligibility criteria. There is no information in the search results to suggest that RE47968 is related to such products or has applied for or been granted a PTE.

Continuation Applications:
A continuation application is a new patent application that claims the benefit of an earlier "parent" patent application, containing the same specification and drawings but pursuing new or different claims. It shares the same priority date as the parent. There is no direct information available from the search results indicating any continuation applications for RE47968.

Divisional Applications:
A divisional application is a separate application claiming a distinct invention disclosed but not claimed in a parent application, typically filed in response to a USPTO restriction requirement. Divisional applications are entitled to the parent's filing date as their priority date. There is no direct information available from the search results indicating any divisional applications for RE47968.

Related Family Members:
A patent family includes U.S. patents or published patent applications that cover the same or similar technical content related to an invention and are related through shared priority documents. Without direct access to the USPTO patent record for RE47968, a comprehensive list of related family members cannot be provided.

Projected Expiration Date:
For applications filed on or after June 8, 1995, the general patent term is 20 years from the date of the earliest related application, or the filing date if there are no earlier applications. This term can be adjusted by PTA and, in specific cases, PTE. Without the original filing date, any PTA, or any PTE information for RE47968, a projected expiration date cannot be accurately determined. One search result from PatSnap indicated an example of a patent filed in 2005-03-15 having an expiry of 2025-03-15, which is 20 years from the filing date, without any adjustments mentioned. However, this was an example, and not directly tied to RE47968.
