- Acted as counsel for the patent owner in two related patent revocations. The patents were revoked by the Registrar of Patents and on appeal to the High Court, the patents were reinstated and the revocations nullified. These were the first two revocations to be heard by the Registrar of Patents and they marked the first time the High Court heard a revocation action on appeal. These cases also marked the first time the High Court had reinstated patents that had been revoked by the Registrar of Patents.
- Acted as counsel on appeal for a patent owner whose patent had been revoked by the High Court. The appeal was successful and marked the first time the Court of Appeal had reinstated a patent that had been revoked by the High Court.
- Acted as counsel for the accused in a private prosecution relating to copyright offences. Despite the convictions at first instance, Vignesh was successful in overturning the convictions before the High Court. This case was notable as it marked the first time the High Court considered whether an accused’s appeal under the former Criminal Procedure Code abated upon the death of an accused. Vignesh convinced the High Court that the death of the accused did not abate upon death and subsequently successfully overturned the accused’s conviction posthumously.
