Dmitrlyn, let me explain something quite simpy as I think there's a lot getting lost here between language and cultural understanding.
In China, there appears to be very little regulation of what goods can be produced and how they are branded or labelled. In China it appears you are free to copy other manufacturers products and names, or at least produce very similar ones.
In the West in most countries its unlawful to make the same or similar goods using a name that's the same or similar to another company, that can cause confusion and lead people to believe that goods from one company could possibly be made by another. I believe this applies to all EU states, Australia, the USA and many more countries besides.
In many Western countries companies can also specifcally register their names to get extra protection against other companies from using them.
To give you a recent example, a pop star called Rhianna, sued a clothing retailer for selling t shirts with her picture printed on them for a reported $5 Million.
She won the case!
I understand that the judge decided that selling t shirts with her face on them implied that she had approved the shirts as she also sold approved fashion branded goods through other retailers and thus the retailer was effectively passing the goods off as one which she had approved.
News reports about the case are here:

I put the 2nd one in because it explains it more simply.
So in the West, selling eg lasers with the same name as another famous Western named company that also makes lasers, would probably also be seen as passing off.
Using a similar name eg XX Lasers, would be seen the same way as well.
I hope this makes it simpler to understand.
