The Case

In the instant case, the defendant had registered a plastic manufacturing patent despite the claimant's objections. The defendant's former employee subsequently admitted to having given perjured evidence during those proceedings and the claimant sought to show that that evidence had displaced the estoppel arising from that decision. Notwithstanding the fact that the evidence upon which the original decision had been based was perjured, it was held that the defendant had had no knowledge of that fact, and, accordingly the claim was dismissed.
