Abstract From the Canadian patent

An RFID webstock containing a relatively high pitch-density array of semiconductive chips is provided and joined to a web bearing relatively widely spaced antennas in a continuous process. The RFID webstock is separated or cut into individual chip sections, with the spacing of the chips being increased as the RFID webstock is die cut. The individual chips on the sections are then joined to corresponding antennas to form an RFID inlay stock. This process is conducive to high speed roll-to-roll production of RFID tag and label roll stock.

Why it's free to use

  • Filed January 17, 2003 and granted December 8, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 17, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 17, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
