Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for processing free-format data (301) to produce a "text object" associated with the free-format data. The text object comprises a plurality of "component nodes" (302-312) containing attribute-type identifiers for elements of the free-format text and other data facilitating access to the text object to obtain information and/or change or add the freeformat data. This arrangement obviates the need for the provision of separate database fields for each element of the information. Free-format data can therefore be processed in a similar manner to the way a human being processes free-format data. All elements can be accessed via the constructed text object.

Why it's free to use
- Filed April 22, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 22, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 22, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
