There are no novel UIs, so copying UIs is okay, and necessary. As for source code, I'm a stickler for the license. The modern set of licenses cover any scenario I can think of, relatively fairly. AI is merely a tool, so the craftsman still owns the output. If the output violates a license, then the craftsman should be held to account.

I’ve seen companies get sued and lose in court for copying UIs. So no, legally speaking, copying a UI is not something that companies ignore.

The look and feel of an interface could be covered under a design patent, which would be a different question than copyright, and a much higher bar to enforce (particularly, protection is far from automatic).

[pryelluw]

You’re talking about enforcement which is a fair point of view, but I’m taking about likelihood of getting sued and having to settle in order to avoid the risk of losing a case in court. Which is the more common case for situations where one company alleges the other stole their IP.

Can you point to cases so I can google them?

Borland Quattro.

In that case no infringement was found though?
