You'll find all the same elements, there. And the copyright notice indicates that it is originally English:

Once again, USPTO patents are just spam, they have no worth, in no sense should you send money to someone pretending to have a USPTO issued patent on your technology, even if they are not from Lagos. Report it to the internet police, as a cyber-scam, do not give out your bank details and certainly don't sent any credit card information.
