Outline of 2003 Interrogator Technology

This outline summarizes RFID interrogator technology innovations that the patent office believed were sufficiently novel in 2003 to issue a patent for.  For each technology, a patent is identified.  These patents have been summarized in detail in technical English in a separate Data Base Appendix document.   A dash number in the patent refers to a specific claim in that patent.  Some of the patents are listed under multiple headings and some technologies are addressed by multiple patents.  Headings with no patents listed are shown for continuity with the interrogator technology Map.
