Questão jurídica principal
Whether the lower court arbitrarily assessed evidence by refusing a design-novelty expert report and witness hearing
Decisão extraída
The refusal was not arbitrary because the proposed evidence was unsuitable or unnecessary to prove prior identical disclosure of the design.
Fundamentação extraída
Novelty is destroyed only by prior access to an identical overall design, not by a merely similar impression. A witness must have direct perception of the relevant facts, which was not shown. An expert report was unnecessary because the issue did not require special technical knowledge and the court need not search through all conceivable means of proof.
