*The support requirement does not demand exhaustive coverage of conditions affecting solution of the problem.
⇒ Support requirement: satisfied
*The lack-of-inventive-step arguments (1) and (2), first advanced on appeal, were rejected as untimely!! (*The judgment does not make clear whether they were advanced in the statement of reasons for appeal.)
(1) The primary reference asserted at first instance + a different secondary reference
(2) An argument changing the interpretation of the primary reference asserted at first instance (the identification of the primary cited invention)
(Excerpt from the court's reasoning) <Support requirement>
…Although it cannot be denied that conditions other than whether the printed regions are continuous or separate could affect solution of the above problem, the support requirement does not demand exhaustive coverage of those conditions and their effects. A person skilled in the art, comparing the claims of the patent with the specification, would be able to recognize that the invention is described as one contributing to solution of the above problem.
