On what grounds would they sue? Not only is it completely legal to copy a competitor's design (in most cases), Uber isn't selling this to other companies.

I don’t understand why the above user is getting downvoted to oblivion by people who don’t understand legalities. Trade dress[1] is a form of intellectual property. This is what prevents a company from copying a competitor down to the pixel. Apple and Samsung fought an infamous and long legal battle over this. [2]

It only matters for product you sell (hence the reference to consumer confusion). Ubers chat sounds like it's solely for internal use.

uChat is a fork of Mattermost, which looks like an exact copy too.

You think Slack came up with that design? Hah.

Check out some screenshots of Discord, that basically looks like "Slack with a dark theme."

And they all look like any generic IRC client with fatter margins and some other 2010+ fluff.

Would need to sue Discord too.

The post says they used an open source chat core called Mattermost.

Only companies with mega deep pockets (to pay the real winners ie the lawyers) would engage in these type of tom foolery.

I am talking about Samsung and Apple here..

Constrained solution space > all chat apps look the same.

Except Snapchat, I still can't work out what that's about.
