Madras HC Rules Against Intra-Court Appeals in Patent Disputes Under Commercial Courts Act

The Madras High Court has delivered a definitive ruling regarding the procedural limitations of challenging patent-related judicial orders. In a judgment delivered on December 12, 2025, a Division Bench of the court held that an intra-court appeal—governed by Clause 15 of the Letters Patent —is not maintainable against an order passed by a Single Judge in a Civil Miscellaneous Appeal (CMA) concerning the Patents Act, 1970.

The Background of the Dispute

The matter originated from the patent application submitted by Italfarmaco SPA (Patent Application No. 10810/CHENP/2012). The Deputy Controller of Patents & Designs had rejected the application under Section 15 of the Patents Act, 1970 . Subsequently, Italfarmaco SPA approached the Madras High Court through a Civil Miscellaneous Appeal ( CMA(PT) No. 45 of 2023 ).

When a Single Judge affirmed the decision of the patent authorities, the appellant sought to challenge that order through an Original Side Appeal (OSA) in the Commercial Appellate Division . This triggered the High Court Registry to raise an objection regarding the maintainability of such an intra-court appeal.

Arguments Before the Court

The appellant argued that the order of the learned Single Judge should be treated as an "order-in-original." Drawing from Clause 15 of the Letters Patent , the counsel contended that because the single judge was adjudicating the correctness of the patent authority's order—much like a writ petition—an intra-court appeal should naturally lie.

Conversely, the court examined the overarching mandate of the Commercial Courts Act, 2015. The respondent pointed out that the procedural framework for commercial disputes is governed by a special enactment that supersedes older provisions, including the Letters Patent.

Legal Analysis and the Primacy of Statutes

The Division Bench, led by Justice S.M. Subramaniam, scrutinized the legislative intent behind the Commercial Courts Act. The court emphasized that the Act is a special enactment specifically designed to govern "commercial disputes" (which explicitly include patent and design matters).

The court noted that Section 13(2) of the Commercial Courts Act contains a "non-obstante" clause: "Notwithstanding anything contained in any other law for the time being in force or Letters Patent of a High Court, no appeal shall lie from any order or decree of a Commercial Division or Commercial Court otherwise than in accordance with the provisions of this Act."

By analyzing this provision, the Bench concluded that the legislative framework strictly limits the types of appeals permitted. Since the order of the Single Judge in a CMA does not fall under the specific categories listed in order XLIII of the Code of Civil Procedure (as required by the Commercial Courts Act), no further intra-court appeal is available.

Key Observations

The judgment clarifies the hierarchy of law regarding commercial litigation:

• On the Supremacy of the Commercial Courts Act: "The Commercial Courts Act is a special enactment and would prevail over the Letters Patent."
• On the Scope for Appeals: "Any expansion of scope of the Commercial Courts Act will defeat its objectives and there is no ambiguity regarding appeals from decrees of Commercial Courts and Commercial Divisions under Section 13 of the said Act ."
• The Final Verdict on Maintainability: "There is no scope to invoke Clause 15 of Letters Patent for the purpose of entertaining the present Original Side Appeal."

Decision and Implications

The High Court upheld the Registry's objection and rejected the appeal as not maintainable. This decision reinforces the objective of the Commercial Courts Act to provide a streamlined, final resolution process for commercial disputes. For practitioners, this serves as a clear warning: the window for appellate remedies is strictly defined by the statute, and parties cannot bypass these limitations by invoking general provisions like the Letters Patent. Future litigants in patent matters must now be prepared for the finality of decisions rendered by the Commercial Division of the High Court.
