Where to put my patches?

I have got a couple of patches for my new gi, and I plan on buying a new academy patch for my other gi. But where to put them? I found this image on the International Brazilian Jiu Jitsu federation home page, I hope it is accurate. I’ve heard rumours that patches on the legs are just a big no-no. Maybe it’s my crappy Japanese? Anyone got the scoop?
