Martin v Scribal Pty Ltd [1954] HCA 48

Patent No. 122073 requires the ink reservoir to follow an 'extended path', which does not include a straight tube; therefore, the defendant's pen does not infringe. Patent No. 133163 was not invalidated for ambiguity on claim construction; however, whether the plaintiff was in possession of the invention at the application date raises a prima facie question and must be determined by further trial on the fifth and sixth particulars of objection.
