To provide a comprehensive overview of US Patent 8411557 regarding its term adjustments, extensions, and related applications, I will detail each aspect based on the patent text and general USPTO rules.

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

The provided patent text for US8411557 does not explicitly state any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE).

  • Patent Term Adjustments (PTA): PTA is granted to compensate for delays incurred by the USPTO during the prosecution of a patent application. This can extend the 20-year lifespan of a patent. The calculation considers various delays by the USPTO, such as failing to issue an office action within 14 months, respond to a reply or appeal within four months, or issue a patent within 36 months of the filing date. Any PTA would typically be noted on the face of the issued patent or in its prosecution history.
  • Patent Term Extensions (PTE): PTEs are generally granted in specific circumstances, such as delays due to regulatory review periods for drugs or other products, or for patents subject to a terminal disclaimer under certain conditions.

Without access to the official USPTO patent record for US8411557 (beyond the Google Patents display), the exact PTA or PTE, if any, cannot be definitively stated.

Continuation and Divisional Applications

The patent 8411557 itself is a continuation of an earlier application. The patent text states its filing date is December 21, 2011, and it claims priority to US13/333,805 on the same date. The patent also explicitly lists "Related Parent Applications" and "Related Child Applications" as part of its family information:

  • Related Parent Applications:

    • US12/293,530 (US8139473B2) - Continuation, Priority Date: 2006-03-20, Filing Date: 2007-03-20
    • PCT/JP2007/055695 (WO2007108476A1) - Continuation, Priority Date: 2006-03-20, Filing Date: 2007-03-20
    • US29353008A - Continuation, Priority Date: 2006-03-20, Filing Date: 2008-09-18

    This indicates that US8411557 is part of a chain of applications originating from the priority date of March 20, 2006.

  • Related Child Applications:

    • US13/781,142 (US8861329B2) - Continuation, Priority Date: 2006-03-20, Filing Date: 2013-02-28

    This shows that US8411557 has at least one direct continuation application filed after its own issue.

Related Family Members

The patent lists a number of family applications, including those claiming priority to the same priority date of March 20, 2006, and those that are continuations. These include:

These applications represent a robust patent family, indicating continued development and protection of related inventions.

Projected Expiration Date

For applications filed on or after June 8, 1995, the patent term is generally 20 years from the earliest claimed priority date. US Patent 8411557 has an earliest priority date of March 20, 2006.

Therefore, the anticipated expiration date for US8411557, without considering any potential Patent Term Adjustments (PTA) or Patent Term Extensions (PTE), would be March 20, 2026.

However, the Google Patents information for US8411557 explicitly lists an "Anticipated expiration" date as 2027-03-20. This indicates that there is likely a Patent Term Adjustment (PTA) of approximately one year associated with this patent, extending its life beyond the standard 20 years from the priority date.

Projected Expiration Date: March 20, 2027
