RCM MintShield - has anyone found that patent(s)

[Anteater]

Following the thread on the petition re RM milk spots, I was just wondering whether anyone has found (or looked for) the patents for RCM's "MintShield"?

The fact it's a "patented technology" (according to https://www.mint.ca/en/bullion/mintshield) should mean that anyone can look at the patents and see (at a high level) what they're doing (or at least, what they might be doing - they might have some unused patents too) - it's just a matter of finding them.

MintShield, I think is just the trade mark for the process. As far as the patents go. I had a quick look but couldn't find much info relating to any patents of the process. On one place it made reference to a coating that was applied during the minting process.

Yeah, "MintShield" won't be in the patents themselves. Searching for "Royal Canadian Mint" at https://www.ic.gc.ca/opic-cipo/cpd/eng/search/basic.html returns quite a lot of result but I haven't looked through them (yet). Trying to work out which patents might be relevant may be difficult.

I did think It might have been applied for by the university, but by that time I was falling asleep.
