Extensions

To determine the details regarding US patent 8,370,543, including patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date, direct access to the USPTO database (Patent Center or Patent Public Search) is required. The USPTO does not calculate expiration dates for patents but provides a calculator and guidance for the public to estimate them.

Based on the information available and general patent law:

• Patent Term: For applications filed on or after June 8, 1995, the term of a U.S. utility patent is generally 20 years from the earliest effective filing date of the application.
• Patent Term Adjustment (PTA): PTA is added to the 20-year term to compensate for certain administrative delays by the USPTO during prosecution. This information is typically provided in the issue notification or on the patent front page.
• Patent Term Extension (PTE): PTEs are typically related to delays in regulatory review, such as by the FDA, and are limited to five years.

For US Patent 8,370,543:

• Filing Date: June 6, 2011.
• Issue Date: February 5, 2013.
• Priority Date: March 9, 2007. This patent claims priority to U.S. Provisional Application No. 60/906,042, filed March 9, 2007, and U.S. Provisional Application No. 60/934,664, filed June 14, 2007. It is also a continuation of U.S. application Ser. No. 12/044,831, filed March 7, 2008, now U.S. Pat. No. 8,145,809.
  • The earliest priority date from a non-provisional application is March 7, 2008 (for U.S. application Ser. No. 12/044,831). The earliest overall priority date, however, is March 9, 2007, from the provisional application. For patents filed after June 8, 1995, the 20-year term is calculated from the filing date of the earliest non-provisional application, or the actual filing date if no earlier non-provisional application is claimed. However, provisional applications are generally not used to calculate the 20-year term for utility patents. Therefore, the earliest non-provisional filing date in the chain is March 7, 2008.

Based on the available information:

• Continuation Applications / Divisional Applications / Related Family Members:

  • This application is a continuation of U.S. application Ser. No. 12/044,831, filed March 7, 2008, which issued as U.S. Pat. No. 8,145,809.
  • It claims the benefit of and priority to U.S. Provisional Application No. 60/906,042, filed March 9, 2007, and U.S. Provisional Application No. 60/934,664, filed June 14, 2007.
  • U.S. Pat. No. 8,145,809 (from application Ser. No. 12/044,831) is an active family member, expiring on 2029-01-06.

• Patent Term Adjustments (PTA): The Google Patents page indicates "Adjusted expiration: 2028-05-10". This suggests that Patent Term Adjustment (PTA) has been applied to extend the patent term beyond the standard 20 years from the earliest non-provisional filing date. The USPTO calculates PTA to account for delays in prosecution. Without direct access to the USPTO's Patent Center for this specific patent, the exact calculation of PTA cannot be provided, but the adjusted expiration date reflects its inclusion.

• Patent Term Extensions (PTE): There is no indication of Patent Term Extensions (PTE) in the provided data. PTEs are typically granted for delays in regulatory review (e.g., FDA approval) and are explicitly noted.

• Projected Expiration Date: The Google Patents record indicates an adjusted expiration date of 2028-05-10. This date incorporates any Patent Term Adjustment (PTA) applied.
