On April 17, 2017 in Reexamination Control No. 95/002,016 of U.S. Patent No. 8,134,450, the PTO issued a Reexamination Certificate confirming the patentability of all original challenged claims (claims 1, 3-8, 10-15, and 17-28) and determining that new claims 29-53 are patentable. The PTAB decision (dated November 21, 2016) confirming the original claims and determining the new claims are patentable stated:
[C]laim 1, for example, instead requires that "the page indicates that the content is available for a specified time" (emphasis added). Claim 15 similarly requires "the notification indicating that the digital content is available for a specified time" (emphasis added). Furuta's transmission of a date-and-time stamp may well satisfy the Examiner's interpretation, but this date-and-timestamp transmission does not satisfy the present claims' actual language, which requires some indication that the availability is for some specified duration. That is, a page merely indicating when the content is sent does not constitute the page indicating that the content is available for a specified time.
