Abstract From the Canadian patent

The invention relates to a method for transmitting real time-critical data using data messages in a data network. The data messages have an identification, useful data and a transfer status. According to the inventive method, data messages comprising errors are replaced by replacement messages that have the same structure as the data messages. The replacement message has the same identification as the data message to be replaced and is thus forwarded via the switching node, which would have been used to route the error-free data message. The replacement message can contain details of the type of transmission error.

Why it's free to use

  • Filed September 12, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 12, 2022.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 12, 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.
