Abstract From the Canadian patent

A robotic arm for transporting products in a product storage and dispensing system is disclosed. The robotic arm broadly includes a base operable to couple the arm to the dispensing system; a sprocket coupled with the base; an extendible arm segment coupled with the base; and a chain coupled with the sprocket and the extendible arm segment such that rotation of the sprocket causes movement of the chain and extension of the extendible arm segment. The robotic arm provides a compact and effective retrieval tool that is compatible with closely spaced and densely packed product shelves.

Why it's free to use

  • Filed February 1, 2006 and granted July 31, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 1, 2026.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
