If a patent-affairs competent person wishes to comment on how right o wrong I am it would be good. - For $50NZ or about $40US you can get a 1 year provisional patent which gives you US priority, and then let it lapse, at which stage it becomes pubic domain BUT supported by patent organisation iorganised prior claim. - While a full patent must be carefully and formally constructed, the provisional patent can consist of about any relevant material you wuish to shovel into it, out of which you must subsequently build any subsequent claims.
