What options are available for free or low cost legally recognized prior art publishing? For prior art to be properly recognized it needs to be publicly searchable and discoverable, and have some sort of permanence of discoverability.
As such although Github might be acceptable for sharing project files, it does not seem to meet the test for being “published” since the content can be removed or made non-public by the project owner at any time.
Also for the same reasons, building your own website to “publish” prior art also seems equally unacceptably ephemeral because it only stays accessible as long as you continue to keep paying to have your server online.
I have wondered if perhaps Archive.org might work as a home for an officially legally recognized prior art archive, due to the fact that they are trying to achieve permanence of the content they host.
