Extensions

For US Patent 6888181, a detailed analysis of its patent term adjustments (PTA), patent term extensions (PTE), continuation or divisional applications, related family members, and projected expiration date is provided below. It's important to note that specific PTA and PTE figures typically require direct access to the USPTO's Patent Center or Public Search systems.

1. Patent Term Adjustment (PTA)
Patent Term Adjustment (PTA) adds time to the 20-year lifespan of a U.S. utility or plant patent to compensate for certain administrative delays caused by the USPTO during the patent prosecution process. These delays include the USPTO failing to: issue an office action within 14 months of filing; respond to an applicant's reply within four months; act on an application within four months after certain board or court decisions; or issue a patent within four months after payment of the issue fee. Additionally, PTA is granted if an application is pending for more than three years, excluding applicant-caused delays.

Without direct access to the official USPTO Patent Center file wrapper for US6888181, the precise PTA granted for this patent cannot be determined. However, the "anticipated expiration" date previously noted (March 18, 2024) is exactly 20 years from the filing date (March 18, 2004), suggesting that any PTA granted was either zero, or offset by applicant delays, or not significant enough to alter the widely reported expiration date based on the standard 20-year term from filing.

2. Patent Term Extension (PTE)
Patent Term Extension (PTE) is available under the Hatch-Waxman Act (35 U.S.C. § 156) for patents claiming products that require regulatory approval prior to being sold, such as human and veterinary pharmaceuticals, food additives, color additives, and medical devices. The purpose of PTE is to restore a portion of the patent term lost during the regulatory review period.

Given that US Patent 6888181 relates to a "Triple gate device having strained-silicon channel" and is in the field of semiconductor devices, it is highly unlikely to have been eligible for a Patent Term Extension under 35 U.S.C. § 156, as it does not appear to claim a product subject to premarket government approval by a regulatory agency like the FDA. Therefore, it is expected that no PTE was granted for this patent.

3. Continuation Applications, Divisional Applications, and Related Family Members
The Google Patents record for US6888181 lists its application number as US10/708,694. The "Priority Applications" and "Applications Claiming Priority" sections both list only US10/708,694, indicating that US6888181 is the primary patent from this application, and there are no directly identified parent applications from which it claims priority under 35 U.S.C. §§ 120, 121, or 365(c) that would result in a different 20-year term calculation.

The "Family Applications" section also only lists US10/708,694 (US6888181B1). This suggests that as of the information available, there are no immediate continuation, continuation-in-part, or divisional applications directly listed within the same patent family on Google Patents. Without direct access to USPTO's Patent Center or Public Search tools, it's not possible to definitively confirm the absence of all potential continuation or divisional applications, but based on the provided family information, none are explicitly identified.

4. Projected Expiration Date
For utility patents filed on or after June 8, 1995, the standard patent term is 20 years from the earliest U.S. filing date, or from the earliest filing date of an application for which a benefit is claimed under 35 U.S.C. §§ 120, 121, or 365(c).

US Patent 6888181 has a filing date of March 18, 2004. Therefore, its statutory 20-year term would typically extend to March 18, 2024. This aligns with the "anticipated expiration" date of March 18, 2024, as noted in the patent summary. As previously stated, the patent's legal status is "Expired - Lifetime" as of this date, confirming its expiration.
