“Radio Frequency Identification Device (RFID) tags are encoded with lengthy serial numbers that uniquely identify particular items. The patent at issue in this case designates the leading bits in a binary serial number as ‘the most significant bits,’ and directs that all serial numbers in an allocated block begin with the same ‘most significant bits.’”
“The question presented is whether that claim, by subdividing a serial number into ‘most significant bits’ that are assigned such that they remain identical across RFID tags, constitutes patent-eligible subject matter under 35 U.S.C. ยง 101.”
