Abstract From the Canadian patent

A tree-structure-conversion processing unit (130a) generates tree-structured data based on generated sequence diagram data. A matching processing unit (130b) retrieves tree-structured data matching with the generated tree--structured data from object tree-structured data (140b). A program-extraction processing unit (130c) obtains a corresponding existing program code from program-code specifying information in the matching tree-structured data and replaces an instance name in the obtained program code to an instance name corresponding to the generated sequence diagram data.

Why it's free to use

  • Filed April 28, 2004 and granted January 22, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 28, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 28, 2026.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
