As far as I can tell, the patent has only issued in the US. You can file a Post Grant Review within 9 months of the grant date of January 30, 2018. This article describes the options for challenging the patent.


the reference to the "Patent" that you cited isn't actually a granted patent, it's only an application that has been published by the USPTO. If you are interested in submitting what you have done so that the patent examiners are aware of it, you can do it by following these directions: http://www.uspto.gov/patent/initiatives/third-party-preissuance-...
