Headnote

A new chemical intermediate product is not inventive merely because it is prepared in the course of an inventive multi-stage process and is further processed to a known end product. Such a product is however at any rate patentable when its further processing is inventive. (Further to "Bis-epoxy ethers/BASF", T22/82, OJ EPO 9/1982, p. 341).
