Extensions

To provide the most accurate and up-to-date information regarding US patent 8587076 from the USPTO database, I would ideally need direct access to the USPTO's Patent Center or Public Pair system. Since I do not have direct, real-time access to these specific USPTO internal systems, I will rely on information typically made publicly available through general USPTO search tools and patent databases that aggregate USPTO data.

Based on the publicly available information, including the Google Patents record for US8587076, here's what can be determined:

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

• The provided Google Patents link for US8587076 includes a section for "Legal status" and "Anticipated expiration". While it lists "Active" status and an "Anticipated expiration" date of 2026-07-24, it does not explicitly detail any specific Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) that led to this date.
• Patent Term Adjustment (PTA) can be granted to compensate for delays caused by the USPTO during the prosecution of a utility or plant patent application. This can extend the 20-year lifespan of a patent.
• Patent Term Extension (PTE) is awarded to compensate for delays incurred in obtaining regulatory approval on a patented product.
• Without direct access to the USPTO's Patent Center for this specific patent, it's not possible to definitively state the exact PTA or PTE calculation, or if any PTE was even applied for (PTE is typically for pharmaceutical or agricultural chemical products requiring FDA approval).

Continuation Applications:

• US8587076 is a divisional of U.S. application Ser. No. 13/037,831, filed on Mar. 1, 2011, now U.S. Pat. No. 8,253,180.
• U.S. application Ser. No. 13/037,831 is itself a divisional of U.S. application Ser. No. 12/505,799, filed on Jul. 20, 2009, now U.S. Pat. No. 7,923,764.
• U.S. application Ser. No. 12/505,799 is a divisional of U.S. application Ser. No. 11/491,260, filed on Jul. 24, 2006, now U.S. Pat. No. 7,579,227.
• The initial application (U.S. application Ser. No. 11/491,260) claimed priority to Japanese Patent Application No. 2005-227457, filed on Aug. 5, 2005.

Divisional Applications:

• As noted above, US8587076 is explicitly stated as a Divisional of U.S. application Ser. No. 13/037,831.
• A divisional application is an application for an invention(s) disclosed in a prior-filed, copending nonprovisional application.

Related Family Members:
Based on the "RELATED APPLICATIONS" section, the following are related family members:

• U.S. application Ser. No. 13/037,831 (now U.S. Pat. No. 8,253,180)
• U.S. application Ser. No. 12/505,799 (now U.S. Pat. No. 7,923,764)
• U.S. application Ser. No. 11/491,260 (now U.S. Pat. No. 7,579,227)
• Japanese Patent Application No. 2005-227457 (priority document)
• US20120273903A1 (publication of US13/547,913, which matured into US8587076)

Projected Expiration Date:

• The anticipated expiration date listed on Google Patents for US8587076 is 2026-07-24.

To calculate the patent term, the general rule is 20 years from the earliest filing date of the application or, if a priority claim is made, 20 years from the filing date of the earliest such application. However, this term can be adjusted by PTA or PTE. Since US8587076 claims priority back to the Japanese application filed on August 5, 2005, the standard 20-year term from the earliest priority date would be August 5, 2025. The listed expiration date of July 24, 2026, suggests that Patent Term Adjustment (PTA) has been applied to extend the term beyond this 20-year mark, compensating for delays during prosecution by the USPTO.
