My father invented this product and I would like to know if it ever went into production and if so who produced it. Is the patent still in effect. Could I use this patent to produce the machine or sell the patent to a company?
It would have expired in 1980 so there are no right associated with it. You, or anyone else, do not need any patent to produce any machine. It is the patent's of others that one must avoid when making this or any other product.
