Changing the organisational structure of something works when you’re trying to reverse engineer a design patent or a trademark.
Trademarks cast a very broad net, they’re not specific to wording but because trademarks deal with imagery “similar enough” is enough for a potential claim. That’s why apple sues any fruit related companies just for having fruit as a logo, because any fruit is “similar enough” in the wide net cast by apples trademark
For example, I can make a design patent on a recipe for food or a burger, but I can’t make a utility patent for the concept of burgers themselves. Changing the organisational structure and ingredients slightly is enough for avoiding liability when it comes to design patents and even trademark intellectual property disputes.
With respect to VR, trademarks on a certain style of headset are not very strong (because many other similar designed headsets exist, so it would not be like a trademark dispute on fruit imagery when it comes to apples trademark), and neither are design patents. It’s the patenting of a certain concept that has the most strength.
