1. Yes. He probably just bought consumer grade (possibly high end) sporting equipment and modified it. 

2. Yes. Maybe he gets funding and raw materials through them and maybe has access to stuff from their R&D department? He might let them patent some of his inventions, but probably only consumer-grade stuff. Like he's not letting anyone get their hands on his XTREME sports gear. Not everyone can handle that kind of XTREME power, and if he gave out exact replicas of his things then everyone would know what his abilities were. But like he could make them some really nice golf clubs. Or like he could prolly make Kosuke some custom equipment.

1.) That's great.

2.) Consumer-grade stuff and special equipment for Kosuke, then.
