Headnote

An invention relating to novel intermediates and novel end products has unity if the intermediates oriented towards the final products are sufficiently closely technically related thereto by the contribution of an essential structural element to the end products and if the regulatory provisions of Article 82 EPC are safegruarded. This is also valid if the intermediates belong to two groups of compounds with different basic structures (Decisions T 110/82 "Benzyl esters" OJ EPO 1983, 274, T 57/82 "Copolycarbonates", OJ EPO 1982, 306 and T 35/87 "Hydroxypyrazoles" OJ EPO 1988, 134 followed and extended).
