Abstract From the Canadian patent

An intermediate transfer belt with a mechanically and electrically invisible seam formed by joining two ends of the belt at a seam. Two regions of the belt are thus formed a seam region at and around the seam and a far region away from the seam. An overcoat is then placed over the seamed substrate such that an outer surface of the overcoat forms a toner-bearing surface. The seam region has good electrical property correspondence (as explained in the patent) with the far region and a lateral resistivity greater than 108 ohms/square. The joining of the belt can occur along a kerf. 43

Why it's free to use

  • Filed November 8, 2000 and granted February 18, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 8, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 8, 2022.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
