A parts list system used for part number management is composed of a parts table database and a parts list controller. The parts table database includes a parts list which stores a state data and a part number data. The state data indicates a progress state of a part. And the part number data includes a number of the part as an identifier. The parts list controller inhibits change of the part number data, when the state data indicates prohibition of the change of the part number data.

Why it's free to use
- Filed March 13, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 13, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 13, 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.
