Recently, the Delhi High Court delivered a landmark ruling in Communication Components Antenna Inc. versus Rosenberger Hochfrequenztechnik GmbH & Co. KG & Ors. (CS(COMM) 653 of 2019), awarding damages of Rs152 crore in a contested patent infringement suit concerning cellular antenna technology. The judgment, authored by Justice Prathiba M Singh, is being hailed as a watershed moment in India’s intellectual property enforcement regime, particularly because it is the largest damages award in a non‑SEP (standard essential patent) matter in the country’s history.
At the heart of the dispute was Indian Patent No. 240893 (“IN’893”), titled Asymmetrical Beams for Spectrum Efficiency. The defendants mounted a comprehensive challenge under Section 64 of the Patents Act, 1970, citing nine prior art documents and raising five statutory grounds of invalidity. These included lack of novelty, lack of inventive step, insufficiency of disclosure, false representation, and non‑patentability.
Justice Singh categorically rejected each ground. On novelty, the court held that none of the cited prior art documents disclosed the core inventive concept of replacing sector antennas with asymmetrical sub‑sector beams while maintaining coverage and reducing handover zones. On an inventive step, the court applied the “person skilled in the art” test and concluded that even the combined teachings of the most relevant prior art (Smith–I and Hagerman) would not lead to the patented solution without inventive ingenuity. The insufficiency objection was dismissed on the basis that the specification’s power and phase coefficients were illustrative embodiments, sufficient for a skilled person to replicate using standard simulation tools. The HC also dismissed the argument that asymmetry in beam patterns was a “mental act,” calling it meritless and affirming that the invention was a concrete, commercially deployed technical solution. In a significant move, the Court directed the Patent Office to issue a Certificate of Validity under Section 113 of the Patents Act, formally endorsing IN’893 and strengthening it against future challenges.
Observers opine that the most consequential part of the judgment was the damages calculation. The court adopted the notional royalty method, reasoning that damages should reflect the licence fee the defendants would have paid at arm’s length. By examining a confidential licence agreement between the plaintiff and CommScope Technologies LLC, a bona fide licensee of IN’893, the HC determined a royalty range. Given the defendants’ evasive conduct, the Court applied the higher end of the range, fixing the royalty rate at 20% of net sale price per antenna. Applying this rate to total infringing sales of USD 6,09,45,991.60 and Rs 1,84,73,47,179.22 disclosed across seven affidavits, the Court awarded Rs 1,52,32,36,783.90 (approximately Rs 152 crore). The damages are payable by 30 June 2026, failing which simple interest at 7% per annum will accrue from 1 July 2026.
For India’s business community, this judgment is a clear signal that intellectual property enforcement is entering a new era. The award demonstrates judicial willingness to impose deterrent damages, aligning India with global IP enforcement standards. It also underscores the risks for companies operating in sectors like telecom, where patented technologies are integral to infrastructure. Telecom operators who purchased infringing antennae, will need to reassess supply chain compliance. The ruling highlights that liability can extend beyond manufacturers to those who knowingly procure infringing products.
“This judgment is the largest award of damages in a contested patent infringement suit in India in a non‑SEP matter. By adopting a 20% royalty rate, the court has sent a clear message: infringers who litigate in bad faith and evade disclosure will face the consequences in law” said Sidhant Goel, Senior Partner, Sim And San – Attorneys At Law
The plaintiff was represented by senior advocate Gaurav Pachnanda, assisted by Sidhant Goel, Mohit Goel, Aditya Goel, Deepankar Mishra of Sim And San Attorneys At Law, and Avni Sharma from Pachnanda’s chamber. The defendants were represented by senior advocate Vivek Chibb, along with the late Varun Sharma and Manish Aryan of LexOrbis.
