I disagree from a practical, as well as financial standpoint.
It's very difficult to patent a software interface design as you have to prove a lack of existence of prior art and the patent must describe the specifics of what you are patenting.
These days there's very little new under the sun. I don't see anything remarkably unique about that particular interface. I'm certainly not saying that it wasn't lifted by their competitor, but that analytics dash also bares a striking resemblance to Google Analytics and a host of others, not to mention Microsoft Excel. Okay, it's blue and has large Helvetica numbers- is that what you're going to patent? Okay, I'll change mine to a green color scheme with Arial fonts. Your patent is no longer enforceable, and your IP attorneys who tend to be paid quite well will charge you tens of thousands of dollars to prove that.
I can imagine it feels like a major violation and annoying to be ripped off, and I don't condone that strategy, but I doubt that CB's competitive advantage is a color scheme and some data labels. A design patent would have basically no value in this scenario.
