These days they are mostly cloning old, usually discontinued, products. Two examples are the Roland 303 or Klon Centaur. One product that isn't exactly discontinued is Neve is continuing to sell 1073 and 33609 derived products, but they certainly aren't selling the original 1073 anymore, and their 33609 design is over 40 years old. I don't morally they have any room to complain about people cloning their old designs, nor that morally should anyone feel bad about taking decades old historic designs from another company and making a version of it that is improved or more accessible.

I'm aware that in the past they were accused of cloning more current products, but the only example I could remember was FCB1010 supposedly being a clone of the Roland FC-300 (MIDI pedal board with 2 expression pedals). There certainly is a visual similarity between the two that seems very questionable. I don't think that the Roland FC-300 was particularly innovative. I know that Mackie sued about the MX-8000 being a clone, but I'll note they did lose that lawsuit. I don't there was also a lawsuit in the 90s about the Aphex Aural Exciter Type C, but I can't say that I know the details of that. Both of those lawsuits are definitely from a time when Behringer's quality seemed to be a lot lower, so there are definately ways the company has improved in the last 30 years.
