The answers obviously lie within the almighty dollar. I think that the park companies make a much better target than the manufacturers do for the simple fact that they have more money. I also believe that this company is hoping for a nice settlement, because this lawsuit isn't exactly a solid rock. The fact that this is happening now...years after the first set of magnetic brakes were installed reeks a little bit. If I'm a judge, I would have that same question, and I think the plaintiffs know that as well. Call me the eternal cynic/conspiracy theorist on this one, but to me it just stinks a little.
1) buy obscure companies that happen to have various patents over the years2) scour the world for anyone who could conceivably be violating any of these patents3) sue the heck out of them and hope for a settlement
I think it's called something like lawsuit harvesting, and that's what this sounds like, particularly in light of how old some of these supposed patent violations are.
Second, it seems as though the contractor selling Disney the braking system would be liable and not Disney. Indeed, most patent infringement lawsuits go after the party profiting from the SALE not from the product's use.
Is the lawsuit claiming Disney stole the design itself and manufactured a system? If so, it seems strange that multiple parks would be named as they would have to be manufacturing the same system design as Disney. It would be as if multiple park operators knowingly (and VERY coincidentally) lifted the same material.
That's why it seems like we have not gotten the entire story
