Potter v Dickenson

The parties to this proceeding were the applicant for a patent, Potter, and the opponent to the grant of that patent, Dickenson. The dispute concerned the award of costs by the Commissioner of Patents following an opposition to a patent application. The matter came before the Supreme Court of Victoria on appeal.

The central legal issue before the Court was the interpretation of the word "costs" in the context of patent opposition proceedings and the extent to which the Commissioner's discretion in awarding costs was reviewable. Specifically, the Court had to determine whether the costs of employing a patent agent and the qualifying fees for witnesses were recoverable as part of the costs awarded.

The Court considered the provisions of the Patents Act 1890 (Victoria) and the Rules of the Supreme Court 1884 (Victoria), particularly Order LXV, rule 27(9). Griffith C.J., in delivering the judgment of the Court, held that the term "costs" in patent proceedings should be interpreted broadly to include all reasonable expenses incurred in prosecuting or defending the opposition. His Honour reasoned that the Commissioner had the power to award such costs as were necessary for the proper conduct of the proceedings, and that this included the fees paid to a patent agent for their expertise and the qualifying fees for witnesses who provided essential evidence. The Court affirmed the principle that the Commissioner's discretion in awarding costs was not unfettered and that the rules of the Supreme Court regarding costs were applicable.

The Court allowed the appeal in part, finding that the costs of the patent agent and the qualifying fees for witnesses were properly allowable. The specific orders regarding the quantum of these costs were remitted for further determination.
