Continuity and Family Data for U.S. Patent 8,671,139

Date of Analysis: April 29, 2026

This report details the prosecution history, term adjustments, and projected expiration date for U.S. Patent No. 8,671,139 ("the '139 patent"). The patent is part of a large and complex family of patents, stemming from provisional applications filed in 2006.

Patent Term and Expiration

• Patent Term Adjustments (PTA): There is no information available from the provided search results to indicate that a specific Patent Term Adjustment was granted for the '139 patent. A detailed review of the file wrapper on the USPTO's Patent Center would be required to determine the exact number of PTA days, if any.

• Patent Term Extensions (PTE): There is no indication of any Patent Term Extension under 35 U.S.C. § 156, which typically applies to delays in regulatory review for products like pharmaceuticals and is not relevant to this technology.

• Projected Expiration Date: Standard patent term is 20 years from the earliest non-provisional filing date. The '139 patent claims priority to U.S. Application No. 11/763,286, which was filed on June 14, 2007. Therefore, the base expiration date is calculated from this 2007 filing date.

  • Earliest Non-provisional Filing Date: June 14, 2007
  • Projected Expiration Date: June 14, 2027

This expiration date does not account for any potential PTA, which could extend the term, or a terminal disclaimer, which could shorten it. A definitive expiration date requires consulting the official records at the USPTO.

Continuity and Application Data

The '139 patent is a continuation application, indicating it is part of a chain of related applications that share the same original specification. This allows later patents to claim the benefit of an earlier filing date.

• Direct Parent Application: The '139 patent issued from Application No. 13/491,454, filed on June 7, 2012. This application is a continuation of Application No. 12/823,709.
• Continuation Chain: The prosecution history reveals a lengthy chain of continuation applications.
  • Application No. 13/491,454 (led to the '139 patent) is a continuation of:
  • Application No. 12/823,709 (filed June 25, 2010, now U.S. Patent No. 8,204,783), which is a continuation of:
  • Application No. 11/763,286 (filed June 14, 2007, now U.S. Patent No. 7,747,745).
• Provisional Priority: The entire family claims the benefit of two early provisional applications:
  • Provisional Application No. 60/804,937, filed June 16, 2006.
  • Provisional Application No. 60/805,119, filed June 19, 2006.

The earliest priority date for the subject matter disclosed is therefore June 16, 2006.

Divisional Applications

There is no information in the provided text to suggest that any divisional applications have been filed that claim priority to the application that resulted in the '139 patent.

Related Family Members

The '139 patent is part of an extensive patent family asserted in litigation. The continuity chain itself reveals several key family members:

• U.S. Patent No. 7,747,745: Issued from the earliest non-provisional application in this chain.
• U.S. Patent No. 8,204,783: The direct parent patent of the '139 patent.
• U.S. Patent Nos. 10,134,054; 11,301,898; and 11,610,226: These patents were co-asserted with the '139 patent in the litigation against Amazon, as noted in the "Litigation summary." While their direct lineage is not specified here, their inclusion in the lawsuit indicates they are closely related family members covering similar advertising technology. The "Priority Applications" table in the provided text confirms a long list of subsequent continuation applications filed after the '139 patent, demonstrating a deliberate strategy by the assignee, Almondnet, Inc., to build a large portfolio around this core invention.
