Open the CIPO recordAbstract From the Canadian patent
Processes and systems for offering and granting digital rights that govern distribution and usage of content, services and resources. The processes and systems provide a basis for flexible business models and negotiation transactions between content providers and users. The concept of meta-rights which permit digital rights to be derived permits upstream parties in a , content distribution chain to dictate rights granted and received by downstream parties. Therefore, each transaction can be considered as a two party transaction between a rights supplier and a rights consumer.

Why it's free to use
- Filed June 5, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 5, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 5, 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.
