No, it's not. It's absolutely standard corporate communications. If they're fighting the lawsuit, that is essentially the only thing they can say about it. Ford Motor Company would say the same thing (well, they'd probably say "meritless and frivolous").
No, this isn't even close to spin, it's just a standard part of defending your case. In the US tort system you need to be constantly publicly saying you did nothing wrong. Any wavering on that point could be used against you in court.
This is a funny thread. You say "No" but then restate the point with slightly different words. As if anything a company says publicly about ongoing litigation isn't spin.
