Section 151 of CPC Takes Center Stage as Judiciary Lowers the Evidentiary Threshold for Pre-Trial Patent Protection

By Legal Editor

New Delhi: July 15, 2026:

The intersection of Standard Essential Patents (SEPs) and Fair, Reasonable, and Non-Discriminatory (FRAND) licensing terms has long been a highly contentious legal battleground. Tech innovators invest billions in developing foundational wireless and video communications architecture (such as 2G, 3G, 4G, 5G, and HEVC), only to face prolonged, exhausting litigation when standard implementers deploy these technologies in millions of consumer devices without active licensing contracts.

 

In a monumental development for international technology law, the High Court of Delhi delivered its decision in the landmark case of . Presided over by Justice Tushar Rao Gedela under Neutral Citation 2026:DHC:5256, this case redefines how interim relief and provisional security are managed within the Indian legal ecosystem.

 

The plaintiffs, a globally recognized research consortium boasting a portfolio of over 31,500 patents worldwide—including more than 1,000 active registrations in India—approached the court alleging extensive infringement. The defendants, Shenzhen Transsion Holdings and its domestic subsidiaries, had been manufacturing, importing, and commercializing budget-friendly mobile devices under popular brands like ITEL, INFINIX, and TECNO since April 2016.

 

Despite nearly five years of persistent outreach and multi-layered licensing negotiations initiated by InterDigital in 2019, the parties reached a complete standstill. InterDigital argued that Transsion was operating as an "unwilling licensee," enjoying a distinct commercial and pricing advantage in the competitive smartphone market by completely avoiding royalty payments. In response, InterDigital filed a patent infringement suit coupled with an urgent application demanding pro tem (provisional) financial security to protect their economic interests during the years it takes to adjudicate a comprehensive intellectual property trial.

Anatomy of the Legal Standoff: Infringement vs. Hold-Out Strategies

 

When the matter escalated, the legal strategies deployed by both corporate entities perfectly illustrated the classic global standoff between patent innovators and technological implementers. The plaintiffs presented an expansive, interconnected portfolio, emphasizing that their cellular and video codecs form the fundamental core of modern telecommunications infrastructure. They heavily leveraged their international enforcement track record, highlighting that various foreign courts had repeatedly validated the essentiality and economic fairness of their global patent portfolio.

 

The defendants, conversely, deployed aggressive patent defence tactics. Transsion robustly contested the demand for pro tem security by pointing out that standard-setting organizations (SSOs), such as the European Telecommunications Standards Institute (ETSI), operate purely on administrative declarations. SSOs do not independently verify the technical essentiality of declared patents, nor do they formally dictate the monetary terms of a FRAND license.

 

Transsion further argued that there is absolutely no statutory presumption of validity for an individual patent just because it is bundled into an institutional SEP declaration. To support their claims of commercial unfairness, the defendants pointed out that specific foreign counterparts of InterDigital’s portfolio had faced partial invalidation or restriction in other jurisdictions.

 

Furthermore, Transsion vehemently complained about a severe lack of financial transparency from the plaintiffs, asserting that InterDigital had withheld highly critical Third-Party License Agreements (TPLAs). Without reviewing these unredacted TPLAs, the defendants argued, it was impossible to deduce whether the current royalty demands were truly non-discriminatory or if they amounted to a punitive, extortionate economic measure designed to force an unfair settlement.

The Judicial Reasoning: Lowering the Threshold for Interim Security

Faced with these competing assertions, the High Court of Delhi chose not to get bogged down in a microscopic evaluation of patent validity at the preliminary stage. Instead, the court’s analytical framework centered around the foundational judicial principle of the balance of equities and the distinct legal separation between an interim injunction and a pro tem security mechanism.

 

Drawing heavy inspiration and binding guidance from foundational Indian legal precedents—most notably Dolby v. Lava and Nokia v. Oppo—the High Court clarified that a pro tem order is essentially a temporary, protective financial arrangement. Its narrow objective is to prevent irreparable financial harm to an innovator while ensuring that the implementer's commercial market operations are not completely halted by an absolute injunction.

 

Crucially, the court explicitly ruled that while a prima facie finding regarding technical essentiality and structural validity is required, the overall evidentiary threshold at this initial stage is significantly lower than the rigid scrutiny applied when a plaintiff demands a complete interim injunction against manufacturing.

| THE DUAL TRACK OF INTERIM IP RELIEF |

+---------------------------------------------------------------------------------+

| INTERIM INJUNCTION DEMANDS: | PRO TEM SECURITY DEMANDS: |

| - Complete Halt to Operations | - Uninterrupted Commercial Sales |

| - Extreme Evidentiary Threshold | - Balanced Financial Protection |

| - Microscopic Patent Scrutiny | - Lowered Prima Facie Burden |

In formulating its prima facie view, the court chose to look holistically at surrounding market indicators rather than isolating individual technical claims. It viewed InterDigital’s extensive matrix of pre-existing global licensing agreements and successful enforcement victories in foreign courts as highly persuasive circumstantial support for patent essentiality.

 

Furthermore, the court strongly rejected the defendants' argument that the non-disclosure of unredacted TPLAs should block the court from issuing provisional relief. Justice Tushar Rao Gedela observed that a detailed exploration of exact FRAND rates belongs exclusively to the final trial stage. Consequently, the non-furnishing of confidential third-party contracts is entirely irrelevant when the court is merely determining an equitable provisional security deposit.

 

The court also scrutinized the commercial conduct of the parties. It observed with concern that Transsion had aggressively scaled its smartphone sales within the domestic Indian market for a decade without setting aside any provisional royalty reserves or extending any formal pro tem counter-offers, despite active knowledge of the underlying patent claims.

Statutory Interplay: Section 151 of the Code of Civil Procedure

From a strict statutory standpoint, the judgment is a masterful exercise of the court's inherent powers under the Indian legal system. Because the specific provisions of the Patents Act, 1970 do not explicitly chart a step-by-step procedural mechanism for pro tem monetary escrows prior to the formal determination of infringement, the High Court invoked Section 151 of the Code of Civil Procedure (CPC), 1908.

 

Section 151 recognizes and preserves the inherent powers of a civil court to make any such orders as may be absolutely necessary for the ends of justice or to prevent the abuse of the process of the court. By seamlessly blending Section 151 of the CPC with the broader equitable principles of patent law, the Delhi High Court firmly established that the absence of express statutory micro-provisions in intellectual property codes cannot bind the hands of a court seeking to maintain commercial equity.

 

The court also deliberately rejected a highly compartmentalized, territory-restricted view of patent evaluation. In the modern telecommunications space, 3G, 4G, and 5G technologies are deeply enmeshed and functionally interdependent.

 

The judiciary recognized that requiring an innovator to prove the technical mapping of hundreds of separate regional patents before receiving any basic financial protection would completely paralyze the enforceability of intellectual property. The court's holistic interpretation prioritized practical commercial reality over pedantic technicalities, effectively insulating the patent holder from protracted "patent hold-out" tactics.

 

Final Judgment: Establishing an Equitable Interregnum

In its final directive, the High Court of Delhi ruled partially in favor of InterDigital, commanding Transsion to promptly deposit a substantial, court-calculated pro tem security amount or, alternatively, furnish an unconditional, encashable Bank Guarantee of an equivalent financial value to the court.

 

To safeguard the highly sensitive commercial metrics, financial models, and proprietary royalty calculations presented during the hearings, the court permitted both the plaintiffs and defendants to formally apply for unredacted copies of the detailed order under strict confidentiality protocols.

 

It is vital to recognize that this pro tem order does not represent a final judicial determination regarding the exact FRAND royalty rate, nor does it guarantee a final victory for the plaintiffs regarding patent infringement. It simply establishes a highly structured, fair, and secure interregnum arrangement.

 

By demanding a substantial bank guarantee, the court successfully insulates the patent innovator from ongoing financial exposure and potential bad-faith delays. Simultaneously, it protects the implementer's commercial ecosystem, allowing Transsion to continue importing, marketing, and selling its mobile brands across India without facing a catastrophic business shutdown.

 

Global Precedent: The Broader Implications for Tech Litigation

The long-term ramifications of the InterDigital v. Transsion decision will reverberate far beyond the borders of New Delhi, fundamentally altering the calculus of global tech litigation. Historically, multinational smartphone manufacturers and device implementers heavily favoured emerging markets for distribution due to lengthy trial timelines, using prolonged litigation delays to force cash-strapped innovators into accepting sub-optimal licensing terms. By lowering the evidentiary threshold required to secure pro tem financial deposits under Section 151 of the CPC, the Delhi High Court has effectively dismantled this strategy in India.

 

This judgment signals to the international legal community that the Indian judiciary is highly sophisticated, commercially aware, and fully prepared to act decisively to protect intellectual property rights. It strikes a carefully calibrated middle path: rejecting the extreme measure of halting a company's commerce via absolute injunctions, while firmly denying implementers a "free ride" during structural legal delays.

 

As wireless standards continue to evolve toward advanced 5G-Advanced and 6G systems, India’s proactive, balanced approach will undoubtedly serve as a foundational blueprint for courts worldwide seeking to harmonize innovation incentives with open market competition.

The Searchable Legal Index: Detailed FAQ on SEP & FRAND Law

[A] Jurisdictional & Procedural Framework

FAQ-01: Under what specific statutory rule did the Court grant the pro tem security?

The High Court of Delhi granted the provisional security by utilizing its inherent powers under Section 151 of the Code of Civil Procedure (CPC), 1908. Since the Patents Act, 1970 lacks an explicit procedural clause for intermediate financial escrows prior to a full trial, the court exercised its inherent authority to ensure the ends of justice and maintain financial equilibrium between the parties.

FAQ-02: Does a pro tem security order mean the court has declared the patents infringed?

No. A pro tem security order is entirely an interim, protective arrangement. It does not decide the final validity of the patents, nor does it confirm actual infringement or dictate the final FRAND royalty rate. Those core issues are left completely open to be decided during the comprehensive trial process.

FAQ-03: What is the fundamental difference between a pro tem order and a standard interim injunction?

An interim injunction is a severe remedy that completely halts the defendant’s manufacturing, importing, and commercial selling operations. A pro tem order, by contrast, allows the defendant to continue their day-to-day commercial operations uninterrupted, provided they deposit an unconditional bank guarantee or cash security with the court to protect the plaintiff against ongoing financial exposure.

[B] Evidentiary Standards & Scrutiny

FAQ-04: How high is the evidentiary threshold for a plaintiff seeking a pro tem order?

The High Court of Delhi explicitly clarified that the evidentiary threshold for establishing a prima facie case for a pro tem security order is significantly lower than the rigorous, microscopic standard required to secure a full interim injunction. The court reviews surrounding market factors rather than conducting an exhaustive technical audit of each patent claim.

FAQ-05: Are standard-setting organizations (SSOs) like ETSI responsible for certifying patent validity?

No. Standard-setting organizations (SSOs) operate primarily on an administrative disclosure system. They do not independently verify the technical essentiality of declared patents, nor do they formulate or certify FRAND licensing rates. The legal evaluation of essentiality and fairness is left strictly to courts on a case-by-case basis.

FAQ-06: Can foreign court decisions be utilized to determine patent validity in Indian courts?

Yes, but only to a limited extent. The Delhi High Court observed that while foreign court decisions upholding the validity and essentiality of an innovator's patent counterparts are not legally binding on Indian judiciaries, they carry strong persuasive value and can be relied upon to form a valid prima facie view at the preliminary stage.

[C] Commercial & Financial Disclosures

FAQ-07: Is the mandatory disclosure of Third-Party License Agreements (TPLAs) necessary at the pro tem stage?

No. The court firmly rejected the implementer’s demand for the mandatory disclosure of confidential TPLAs at this preliminary juncture. The court reasoned that because a pro tem security order does not fix the final, permanent FRAND rate, the non-furnishing of unredacted third-party agreements is entirely irrelevant to granting provisional financial protection.

FAQ-08: Why did the court choose to view the wireless patent portfolio holistically?

The court rejected a territory-restricted, compartmentalized view because modern wireless communication standards (3G, 4G, 5G) are inherently enmeshed and globally unified. Requiring an innovator to exhaustively map every single regional patent before receiving basic provisional security would render intellectual property rights practically unenforceable due to intentional litigation delays.

FAQ-09: What constitutes an "unwilling licensee" based on the court's analysis?

An implementer may be categorized as an unwilling licensee if they continuously manufacture and sell commercial products utilizing declared SEPs for an extended duration without a license, fail to present transparent, reasonable counter-offers, and do not set aside any financial reserves or pro tem security deposits despite years of active outreach and multi-layered licensing negotiations by the patent holder.
