Yes, this works great as it gives the recipient proof of date of invention -
that on the date the item was mailed, it was in that state. Unless anyone
can "prove" an earlier date of invention, this is a sure-fire method.
Note - in order for this to be effective send it registered, return receipt
requested, and make sure the postman hand-stamps the postmark on all seams
of the envelope - this is to prove that the item was never tampered with
from the date of the postmark.
