Open the CIPO recordAbstract From the Canadian patent
A system and method for localizing an aggregated electronic program guide (EPG) schedule covering a plurality of service environments includes an information filter located at the subscriber's set-top box conditioned to recognize which schedule information is relevant to the viewer's service environment. Only schedule information corresponding to the viewer's own service environment is stored in the EPG's schedule database. The result is an electronic program schedule that is tailored to the viewer's specific service environment without the use of costly equipment on the transmission side of the program schedule feed.

Why it's free to use
- Filed June 6, 1996 and granted December 11, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 6, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 6, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
