When you knit chainmail, you are creating a weave of a specific pattern, like European four-in-one, Japanese six-in-one, boxchain, or birdcage, to name a few. New weaves can be invented, but tend to be sporadic occurences. At least one person has tried to patent their new weave; I think it is called orchid. This is seen as rather stupid and pointless by the rest of the chainmail community - chainmaillers tend to share everything they know.
