So a reading from a copyright lawyer on the case/filing, and covers general ideas of the law that might apply too as it generally works (what is copyrightable within a work, what sorts of tests are used in the real world, some real life examples of things and more besides)
Short version of that. Ubisoft does not have a great case if that filing is what we have to go by (which in turn is what the courts have to go by). Whether it would be dismissed outright I don't know but I would not bet against it, especially if they are not given leave to file additional evidence of copying/infringement.
I did not catch in that why Google and Apple got pinged. He speculated if they failed to do their job under the DMCA notifications procedure which I would doubt they would at some level, and I am not sure they have any duty to make a judgement on this game.
To add to it. I would like to note orange and blue (or orange and teal if we are being fancy) are considered complementary colours, indeed one of the main examples in popular use, which every design student, art student and the like that learned the first thing about colour theory will tell you.
on film posters but does make the case, and

I thought at first this might be a case of ripped or recreated copyrightable assets, seems not though and at least in what Ubisoft presented in their document. If someone has a further analysis on something that might actually have been copied I am interested to hear about it, however I will note that if you are going to go to court then you do generally want to do a good job first time. In the video above, and for my purposes as well, I would be interested to see what the fictional equivalents might be between the games as those stand a better chance of rising to the level of infringement (though even then from what I saw in that I have a long list of real world equivalents and works of fiction featuring them).
It is a shameless attempt by ejoy to try to get in on the action? Oh yeah. Does it reach the level of copyright infringement? Not from what Ubisoft presented there, and if there is then it is absolutely minimal and does not speak at the core of the gameplay. To that end Ubisoft are probably the bad guys here.
Now the real world weapons it lists in the game might be troubled if the weapon manufacturers themselves cared to file suit (assuming ejoy did not get permissions for such a thing, which I would not put any money on happening but I have been surprised in the past) but that is a different matter.
