Open the CIPO recordAbstract From the Canadian patent
Objects that are managed within a run-time environment are stored on N-bit aligned addresses. Due to the alignement restriction the N least significant , bits of a reference to an object are available for storing information about the storage properties of the object. This information is extractable by fast register operations. The storage properties can include the lifetime format, and contiguity of the object, or a combination of these properties. If the runtime environment implements a generational garbage collector the reference , tags are used to encode whether or not the object is recently allocated.

Why it's free to use
- Filed February 11, 2000 and granted October 28, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 11, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 11, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
