If someone can decipher the formula, anyone can produce it and sell it.
The use of the word Hy-Tran is a trademark thing and is a "live" trademark.
First registered on October 13, 1959.
Others can pay the trademark owners to have it on their label.

No need to decipher anything on a patented item. Its all in the patent and that's a public record. All you have to do it look it up and make it (that's why drug companies have all sorts of little tricks to extend their patents)! Since HyTran is a spec (maybe there is a patent to THEIR formula that meets the HyTran standard?) its sort of a moot point. I can tell you that Navistar charges vendors to purchase their specs so they could manufacture products to meet their standard. I doubt it was any different in the IH days. So someone IS paying to put "HyTran" on that bottle and it has to meet spec to get it on the bottle.
I knew I would get right in the middle of this again...
I wouldn't run the generic stuff in brand new equipment either until out of warranty. No excuses (no matter how goofy) for them to whine about honoring the warranty. If I became rich and could afford to buy a brand new vehicle I'd take it to the dealer that sold it for services until it was out of warranty too.. No excuses.
