At my previous company all drawings for patents had to be black&white 
line/vector art. 3D stuff was normally done in CAD and then exported as 
a bitmap (most CAD software lets you set to "wireframe" and choose a 
line thickness / output quality). Although I never used POV for these 
type of images, I suppose the easiest way would be to render in high 
contrast (black objects on a white background) and then post-process in 
photoshop or similar with an edge detector.
