Nobody on the face of the Earth would confuse NReal with Unreal.
Similarly, Epic haven't defended their "Unreal" trademark in China against Nreal because trademark laws there are actually sensible: sure, if someone counterfeit their engine it is unlikely that there would be a case against it (which contrary to first impressions counterfeiters tends to be a small operation and can quickly shut down when there's signs a legal trouble) but if a Chinese company flagrantly displayed the Unreal trademarks against Epic's wishes, they can sue it (and it happened already and prevailed a couple of times there).
Unreal could argue there is no confusion and they'd be in the clear. In fact they have many avenues between "lawsuit" and "losing their trademark". If you disagree, please actually list applicable precedents indicating otherwise.
