Can you publish details (or a link thereto) to solidify the prior art? IIRC, not only the fact of success but also the methods used must be published to establish prior art.

One of the best ways to do this may be to file a Provisional Patent application. It costs $100, and is a write-up of the outline and methods/technology used. The patent office does nothing but leave it in a drawer. If you file a proper patent application referencing it within 365 days, then it becomes part of the new patent and holds your priority date. If you don't then the contents of the Provisional Patent app becomes public domain - now fully and authoritatively documented public domain.
