You seem to connect ASTM and IP concerns. I don’t see how they are connected.
GAMI doesn’t have infinite IP protection. They have patents that eventually expire. And their STC would provide a bit of protection, but if they go crazy with it, someone else can submit for their own STC.
And my understanding is that GAMI has specific concerns about ASTM members violating ASTM secrecy rules. So maybe they should play ball anyway, but it doesn’t seem like getting an ASTM spec would necessarily unlock the distribution issue. The incumbents still won’t want their trucking partners distributing a fuel they don’t want to exist and will have the same leverage over them.
