The official name of Siemens is Siemens

SIMENS is not Siemens of Germany

I have never heard of this trademark. If you see it, there may be two reasons

The first is a mistyping. For example, some companies sell some Siemens products. Due to unfamiliarity and small business volume, the mistyping was not found;

Or some The media (especially websites) occasionally mention Siemens in their articles, but they make mistakes because they don’t understand and the references are not important;

The second is misleading, such as selling telephone switches. Due to the chaos in the domestic market, counterfeiting is common ( I also bought TCL Ace (in fact, TCL does not produce PBX), especially Siemens has a very stable brand in the telecommunications field, and there are many counterfeits

And according to national regulations, different industries do not count as counterfeits. For example, Siemens does not produce cakes. If you register a "Siemens" brand cake, it is legal, not to mention that someone else has changed a letter
