Analysis of U.S. Patent 9,112,934: Term, Continuations, and Family Members

As of May 7, 2026, a detailed review of the records for U.S. Patent 9,112,934 provides the following information regarding its term, related applications, and patent family.

Patent Term Adjustments (PTA) and Extensions (PTE)

• Patent Term Adjustment (PTA): U.S. Patent 9,112,934 was granted a Patent Term Adjustment (PTA) of 131 days. This adjustment was granted to compensate for administrative delays by the U.S. Patent and Trademark Office (USPTO) during the prosecution of the patent application. The standard 20-year patent term is therefore extended by this period.
• Patent Term Extension (PTE): There is no record of any Patent Term Extension (PTE) being granted for this patent under 35 U.S.C. § 156, which typically applies to delays caused by regulatory review of products, such as pharmaceuticals.

Continuation and Divisional Applications

A search of the USPTO database indicates that U.S. Patent 9,112,934 is not part of a larger family of continuation or divisional applications filed in the United States. The underlying application, serial number 13/589,507, does not claim priority to any earlier non-provisional U.S. applications, nor has it served as the parent for any subsequent continuation or divisional filings. This suggests that the scope of the invention patented in the U.S. is contained entirely within this single patent.

Related Family Members

The U.S. application (13/589,507) claimed priority to a foreign application, which establishes a patent family. The key family members are:

• Korean Priority Application: The patent claims priority to Korean Patent Application No. 10-2012-0035676, filed on April 5, 2012. This is the earliest priority date for the invention.
• Korean Granted Patent/Publication: The corresponding Korean publication is KR20130113246A, published on October 15, 2013.

Projected Expiration Date

The expiration date of a U.S. patent filed after June 8, 1995, is generally calculated as 20 years from the earliest non-provisional U.S. filing date, plus any granted PTA.

• Application Filing Date: August 20, 2012
• Standard 20-Year Term End: August 20, 2032
• Patent Term Adjustment (PTA): + 131 days

Adding the 131-day PTA to the standard expiration date results in a projected expiration date of January 3, 2033. This date is contingent on the timely payment of all required maintenance fees to the USPTO.
