The grooves (2,3) are filled at least, with a, liquid resin, which is at least partially, solidified in the, grooves (2,3) and thereafter separated from the clich?

Why it's free to use
- Filed August 11, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 11, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 11, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
