I don't think it's a good comparison. Wyrm's deformer kits are a quite specialised tool for a particular task (modifying body geometry). Lighting arrangements, on the other hand, are a requirement in any CGI. There are many possible arrangements depending on the sort of image you want to create. If I look back at my scene files, I will see all sorts of set-ups: the classic four-light scheme, numerous dim lights (to say this is anyone's new invention is absurd), single spots, pseudo-stage lighting and many other arrangements designed to enhance each individual scene. To try and assert any rights over one lighting arrangement would be like trying to patent curry.
