Abstract From the Canadian patent

Apparatus is provided for the treatment of a medical condition such as mucositis in patients who are undergoing cancer treatment. The apparatus has several embodiments. In each embodiment an array of optoelectronic devices, such as light-emitting diodes (LEDs) is used to provide a uniform emission of monochromatic light while producing a minimal amount of heat. The LEDs may be cooled in several ways. The treatments are typically of a very short duration in several embodiments selected portions of the patient are treated using a hand-held or stationary lamp. In other embodiments the entire gastrointestinal tract may be treated simultaneously.

Why it's free to use

  • Filed February 26, 2002 and granted April 23, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 26, 2022.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 26, 2024.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
