That's a great comparison! To compare, the Bakugan tabletop game and anime were released before the videogames. However, the Bakugan videogames were planned first, and then the tabletop game and anime were planned later. Thus, the tabletop game and anime wouldn't exist if the videogames were never planned in the first place.
I'm not upset nor ranting/complaining, but I'm sorry, Bakugan was still originally intended to debut as a videogame. The Bakugan characters were created for a videogame, and thus, Dragonoid is still a videogame character because of the intentions behind the Bakugan franchise.
To answer your question, the now Bakugan franchise is currently co-owned by Sega and Spin Master. I think Sega owns rights to all the Bakugan characters.
To add on, Bakugan is now one of those now-obscure Pokemon clones, along with Medabots and Monster Rancher. It was once iconic during the Wii era.
