Subject: Patent Term and Family Data for U.S. Patent No. 9,766,801

This report details the prosecution history and term-related information for U.S. Patent No. 9,766,801 ("the '801 patent").

Continuity Data

The '801 patent is a continuation of U.S. Patent Application No. 13/822,709, which was filed on March 12, 2013, and is now U.S. Patent No. 9,292,168. This earlier application was the §371 national stage entry of International Application No. PCT/JP2011/070942, which was filed on September 14, 2011. The PCT application, in turn, claims priority to Japanese Patent Application No. 2010-208169, filed on September 17, 2010.

Therefore, the earliest priority date for the '801 patent is September 17, 2010.

Patent Term Analysis

• Standard Term: For patent applications filed on or after June 8, 1995, the standard patent term is 20 years from the earliest non-provisional U.S. or PCT filing date. In this case, the relevant date is the PCT filing date of September 14, 2011. This would result in a standard expiration date of September 14, 2031.

• Patent Term Adjustment (PTA): The United States Patent and Trademark Office (USPTO) grants Patent Term Adjustment to compensate for certain delays in the patent examination process. A review of the prosecution history for the '801 patent indicates that a PTA of 53 days was granted by the USPTO. This adjustment is added to the end of the standard patent term.

• Patent Term Extension (PTE): There is no indication that the '801 patent has been granted any Patent Term Extension (PTE) under 35 U.S.C. § 156. PTE is typically granted for delays in the regulatory review process for products such as pharmaceuticals and is not applicable here.

• Terminal Disclaimers: No terminal disclaimers have been filed in relation to this patent, which would have otherwise shortened its term.

Projected Expiration Date

The projected expiration date is calculated as follows:

• PCT Filing Date: September 14, 2011
• Add 20 Years: September 14, 2031
• Add PTA of 53 days: November 6, 2031

Based on this information, the projected expiration date for U.S. Patent No. 9,766,801 is November 6, 2031. This date is contingent on the timely payment of all required maintenance fees.

Patent Family Members

The '801 patent is part of an international patent family. Related patents and applications have been filed in other major jurisdictions, including:

• Japan: JP 5671043B2
• Europe: EP 2618991A1, EP 2618991A4, EP 2618991B1
• China: CN 103097950A, CN 103097950B

This indicates a broad international filing strategy for this technology.
