Questione giuridica chiave
Whether the cassation court wrongly held that the defendant had already addressed the new patent-law claims and therefore suffered no denial of hearing.
Decisione estratta
The defendant had not materially addressed the new patent-law claims; the cassation court's contrary view was untenable.
Motivazione estratta
His submission of 30 March 2001 contained only procedural requests and did not amount to a substantive response to the later patent-based allegations.
