No, Tanemura Sensei does not "own" Seionage, Omote Gyaku (actually means "outside reverse", it would need Kote in there to refer specifically to the wrist, and there is no actual mention of "locking", so you know), or anything like that. However, he does own Genbukan Ninpo, Kokusei Jujutsu Renmei, Tanemura-ha Koto Ryu, Tanemura-ha Togakure Ryu, and each of the other branches and Ryu-ha that he holds the headmastership to. As to the names being generic, well, kind of. But the term used in one system does not really mean the same thing in another system, so while Omote Gyaku is a fairly common (although not the exclusive, or only used term for such actions) term, the exact methodology employing such a techinque is greatly varied from Ryu to Ryu, and each of those methods are then the "property" of the Ryu, and it's sole holder, the Soke, Shihanke, or otherwise.
My apologizes for not using the term with"kote" which confused modern Practitioners.

It is a generic name and why since you corrected me are you not refering it as Omote"kote"gyaku is because you knew what I was refering to when I typed "Omote gyaku" in the first place? If we are using generic words in Japanese
how can we say that someone owns this? Lets use generic words in English:
Body drop,foot sweep,wrist lock can we really say that someone owns these?
If you want to put something fancy like"Dragon crushes tiger" and it is a wrist lock and you copy righted it and someone else uses it and uses the same name then yes that is violation of Intellectual property.
Using a wrist lock same as "Dragon crushes tiger" but calling it "armbar" most likely will not be Intellectual property violation depending on the circumstances.
Look at Kimura lock,chickenwing,reverse keylock who owns this? It is used by everyone. Who owns the Jab? Who owns the double leg take down?
Throw a Japanese name on it or a Chinese name on it. It is the same thing only with a Japanese or Chinese name.
