| Headnote: | A chemical substance is held to be new if it differs from a known substance in a reliable parameter. The configuration is such a parameter. If the prior art describes specific racemates in more detail by reference to their structural formulae, that alone does not disclose their specific configurations (here D- enantiomers); see points 6 and 7 of the Reasons (in conjunction with T 12/81 "Diastereomers", T 181/82 "Spiro compounds" and T 7/86 "Xanthines" in OJ EPO 1982, 296; 1984, 401; and 1988, 381 respectively). | ||||||||
