Probably not, if you're a designer who comes up with original concepts for a living. Sometimes imitation crosses the line and becomes outright copying, and it's interesting to see the just how blatant some of this design copying is. Now there is a whole museum dedicated to showcasing it.
The Museum Plagiarius (or Plagiarism Museum) of Germany. Awesome.
(Oh, and I really like the design of the building it's in too. I wonder if anyone will copy it?)
