It's interesting that they are selling it openly. It still falls under the V-Cube patent, and they're selling all the other 5x5-11x11 cubes "under the table" because of that.
Also, why does Cubezz care about that patent? Nobody else does. It's not like The Cubicle or SCS or whoever restricts what they sell and, being in the US, are far more likely to have patent issues than a company in China.

Yes, the patent goes up to (including) 11x11, although iirc the highest order cube that V-Cube has physically produced so far is 9x9. 12x12 and up is fair game. Which kind of shows how dumb the patent restriction is, since there's nothing new/different about 12x12+ mech, but that's a different story.

Cubezz cares about it because V-Cube used to complain to Paypal about them, "this merchant sells counterfeit goods". Idk why other stores are doing fine wrt Paypal; maybe V-Cube doesn't care much these days and Cubezz just continue operating how they had to a few years ago?

On a side note, Rubik's is very active about "counterfeit goods" as well; there is a popular local Craigslist-like website where I occasionally sell a cube or two, and Rubik's employs an agency (Yellow Brand Protection) that hunts and shuts down even private ads (a person selling a used physical item, in this case). It's *that* bad.

how does the V-cube patent work?
yuxin qiyi and moyu are also selling 5x5-11x11 cubes to the public. why they can sell cubes on the table but shengshou cannot?
what about shengshou mr.m 5x5?

Who says that Shengshou cannot? :)

China law mostly turns a blind eye to Chinese companies violating patents of foreigners. Moyu, Yuxin, Shengshou etc etc don't have to care that their products are technically knockoffs. Unless a foreign company has significant presence in Chinese market to enforce things, go to local courts and such, there is little they can do.

However, what V-Cube can do is use their leverage outside China. In particular, they file abuse claims to Paypal, etc. Or, at least, they used to do this. Bottom line is: manufacturers don't care, but stores do care. Actually, I'm not sure why Cubezz suffers from V-Cube, but TheCubicle or SpeedCubeShop don't.

The patent by V-Cube covers the general idea of the mechanism used in all modern big cubes. Even if, for example, Aofu GTS has an extra protruding lip on the 2nd layer for stability, it's still a minor modification of the same underlying concept that enables the pieces to hold together in the first place.
