Extensions

To accurately detail patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, and the projected expiration date for US patent 8327051, I would typically need to directly access the patent's file history in the USPTO's Patent Center or Public Search tools. However, as an AI, I cannot directly interact with these live databases.

Based on the provided patent text and general knowledge of patent law, here's what can be inferred and what would require direct USPTO record access:

For US Patent 8327051:

• Patent Term Adjustments (PTA):
  PTA is granted to compensate for delays caused by the USPTO during the prosecution of a patent application. The patent document itself does not explicitly state any PTA awarded. To determine if any PTA was granted, and the duration of such adjustment, the patent's prosecution history on USPTO Patent Center would need to be reviewed.

• Patent Term Extensions (PTE):
  PTE is awarded to compensate for delays incurred in obtaining regulatory approval on a patented product, typically for pharmaceutical products. The patent's subject matter ("Portable handheld memory card and methods for use therewith") does not suggest it would be eligible for PTE, as it's unlikely to require regulatory approval under 35 U.S.C. § 156. However, a definitive answer would require examining the patent's official file for any PTE requests or grants.

• Continuation Applications, Divisional Applications, and Related Family Members:
  The patent lists "US11/986,389" as its application number and "US20090132739A1" as an "Other version," which is a publication of the patent application. This indicates that US8327051B2 is likely a direct grant from application US11/986,389.

  • Continuation Application: A continuation application allows an applicant to pursue broader, narrower, or differently structured claims from a parent application, using the same specification, as long as the parent application has not issued or been abandoned.
  • Divisional Application: A divisional application is filed when the USPTO issues a "restriction requirement," meaning the original application contained multiple distinct inventions. The applicant can then pursue the non-elected inventions in a divisional application.
  • The provided information does not explicitly state that US8327051B2 is a continuation or divisional of an earlier application, other than referring to its own application number US11/986,389. To definitively identify any continuation or divisional applications, or other related family members (beyond the published application), a detailed search of the patent family in the USPTO database would be necessary. The "Applications Claiming Priority" section lists only US11/986,389, suggesting it's the direct progeny of this application.

• Projected Expiration Date:
  For U.S. patents (other than design patents) issued from applications filed on or after June 8, 1995, the term generally ends 20 years from the earliest filing date of the application or a prior U.S. non-provisional or PCT application from which it claims priority.

  • Filing Date: November 20, 2007
  • Standard 20-year term calculation: November 20, 2007 + 20 years = November 20, 2027.
  • Anticipated expiration listed in Google Patents: The Google Patents page for US8327051B2 explicitly states an "Anticipated expiration" date of 2027-11-20. This aligns perfectly with the 20-year term from the filing date. This date would be further adjusted by any PTA or PTE, but the Google Patents entry does not indicate such adjustments.

Therefore, without access to the full prosecution history from the USPTO Patent Center, the projected expiration date is November 20, 2027, based on the 20-year term from the filing date, and assuming no PTA or PTE has been granted that would alter this date.
