Maybe, does UBS have a branch in the US that you can sue? Alternatively, does the country you are in treat foreign standards as admissible in their court in some form? Does the country have their own version of NIST that is willing to "leverage" the work of another country into their own standards, thus making the NIST standard a national standard for their country? Does the country have their own version of NIST that has already issued a standard? Any of the above are angles to consider before you reject legal approaches to the problem just because the country doens't apply.

Your question is one of the reasons I didn't say the legal route was a better way. It is an option that may get better results in some cases. Even in the US it may not always get the best result.
