In the past it was illegal to export cryptography, which lead to some ridiculous situations. I once found an export restriction that says it's illegal to export neural network technology (or at least if it's applied to ASICs or FPGAs.) I doubt many people in the industry are familiar with this. Now that Google is starting to produce NN ASICs and Intel is building NN instructions into its chips, this is a serious concern.
Export regulations have been relaxed since 1996 in the U.S. but export is still regulated and may require review and license from Department of Commerce's Bureau of Industry and Security.
