Introduction
The labyrinthine domain of patent law presents an array of challenges, especially regarding the enforcement of patent rights and the maintainability of infringement suits. In India, the Indian Patent Act, 1970, encapsulates the provisions for patent infringement between sections 104 and 114. However, a conspicuous absence of explicit definitions and stipulations concerning the maintainability of infringement actions accentuates the complexity of this legal terrain. This article delves into the intricacies of patent infringement under Indian law, juxtaposes it with the statutes of the US and the UK, and explores the paradigm shifts observed in these jurisdictions that advocate for granting interim injunctions even before a patent is formally granted. The discussion will culminate in advocating for a similar evolution in Indian patent jurisprudence.
Patent Infringement under the Indian Patents Act, 1970
The Indian Patent Act of 1970, an exemplar of legislative acumen, bestows upon patentees an arsenal of exclusive rights encapsulated in Section 48. This provision empowers patentees with the sovereign prerogative to preclude third parties from manufacturing, importing, using, offering for sale, or selling the patented product or process. By implication, any encroachment upon these sacrosanct rights constitutes an infringement, thereby warranting immediate and decisive legal recourse. However, the Act remains conspicuously reticent on providing an explicit definition of ‘infringement’ and elucidating the precise criteria for the maintainability of an infringement suit, thus engendering a realm of interpretative ambiguity.
Detailed Examination of Indian Patent Law
Provisions and Rights Under the Indian Patent Act
The Indian Patent Act of 1970, while comprehensive in its scope, harbours certain ambiguities, particularly concerning the maintainability of infringement suits. Section 48, as aforementioned, endows patentees with exclusive rights, yet it is Sections 104 to 114 that meticulously delineate the procedural aspects and substantive grounds of infringement actions.
- Section 104: This provision stipulates the jurisdiction of courts in patent infringement cases, conferring authority upon designated judicial bodies to adjudicate disputes pertaining to patent rights. It serves as the judicial gateway through which patentees can seek redress for violations of their exclusive rights.
- Section 105: This section allows for a declaration of non-infringement, enabling entities to seek judicial confirmation that their actions do not constitute an infringement of the patent in question. This pre-emptive measure serves to obviate potential litigation by providing a definitive legal resolution to disputes over the scope of patent rights.
- Section 106: This provision provides for an array of reliefs in suits for infringement, encompassing injunctions to restrain further infringements, damages or accounts of profits to compensate for unauthorized exploitation, and orders for the seizure and destruction of infringing goods. These remedial measures are designed to restore the patentee to their rightful position and deter future infringements.
- Sections 107-111: These sections cover defenses in infringement suits, including grounds for revocation of the patent and the various remedies available to patentees. They delineate the legal arsenal available to alleged infringers to contest the validity and enforceability of the patent, thereby ensuring a balanced adjudication of patent disputes.
Despite the detailed procedural framework provided by these sections, the Act does not explicitly define ‘infringement,’ nor does it clarify the criteria for the maintainability of infringement suits during the pendency of the patent application. This legislative lacuna has necessitated a plethora of judicial interpretations, resulting in a patchwork of legal precedents that seek to fill the gaps in statutory provisions.
Judicial Interpretations and Case Law
Unilin Beheer B.V. v. Balaji Action [CS(COMM) 1683/2016]
The august Delhi High Court, in its sagacious adjudication of Unilin Beheer B.V. v. Balaji Action, profoundly elucidated the imperative of patent validity as a sine qua non for the conferment of any relief in infringement litigations. This juridical pronouncement was a paragon of judicial erudition, resonating harmoniously with the tenets of Section 114(1) of the Indian Patent Act, 1970. This section, which stipulates that any relief granted in proceedings for patent infringement is predicated upon the veracity and legitimacy of the patent claims in question, served as the fulcrum of the Court’s reasoned judgment.
In this case, the Court meticulously examined the intricate tapestry of the patent’s claims, accentuating that the bedrock of any infringement relief must be the incontrovertible validity of the patent itself. The legal rationale underpinning this decision is both cogent and compelling: a patent, being a statutory creation, must incontrovertibly withstand the crucible of validity before it can be wielded as a sword in infringement proceedings. The judiciary, in its wisdom, posited that an invalid patent, bereft of its foundational legitimacy, could not, in good conscience, be the basis for any judicial relief.
The Court’s exegesis on Section 114(1) was both perspicacious and exhaustive, delineating that the grant of relief is inexorably intertwined with the demonstrable validity of the patent claims. This interpretative stance underscored a cardinal principle of patent law: that the edifice of patent rights must be constructed on the impregnable bedrock of validity. The Delhi High Court’s verdict, thus, not only reaffirmed the sanctity of Section 114(1) but also fortified the jurisprudential framework governing patent infringement in India.
Novartis AG & Anr. v. Natco Pharma Limited [CS(COMM) 229/2019]
In the illustrious case of Novartis AG & Anr. v. Natco Pharma Limited, the Delhi High Court further expounded upon the doctrinal tenets of patent law, delivering a landmark ruling that resoundingly affirmed the principle that infringement actions are maintainable exclusively for granted and extant patents. This juridical exposition was a testament to the Court’s unwavering commitment to upholding the integrity of patent rights while simultaneously safeguarding the legal framework from potential abuse.
The Court, in its sagacious deliberation, emphatically pronounced that any infringement action predicated on an unregistered or revoked patent is inherently untenable. This ruling was a juridical masterstroke, meticulously aligning with the statutory prescriptions of the Indian Patent Act. The Court’s interpretation was unequivocal: a patent that has not been duly registered, or one that stands revoked, cannot, under any circumstances, form the basis of a legitimate infringement claim.
In its reasoning, the Court underscored the paramountcy of the patent’s legal status as a pivotal criterion for maintainability of infringement actions. The judiciary elucidated that the statutory rights conferred by a patent are contingent upon its registration and subsistence. An unregistered patent, lacking the imprimatur of legal recognition, or a revoked patent, stripped of its statutory protections, is devoid of the requisite legal sanctity to sustain an infringement suit.
This landmark ruling by the Delhi High Court not only reinforced the doctrinal underpinnings of patent law but also served as a clarion call for the sanctity of statutory compliance in the realm of intellectual property. By precluding infringement actions based on unregistered or revoked patents, the Court fortified the legal bulwark protecting patent rights, ensuring that only those patents that have withstood the rigorous scrutiny of the statutory process can be the basis of judicial enforcement. This decision, thus, epitomized the judiciary’s role as the sentinel of statutory fidelity and the arbiter of legal propriety in the domain of patent law.
The US Perspective: Provisional Rights and Judicial Precedents
35 U.S.C. § 154(d) and Its Implications
The US patent system, in its prodigious wisdom, has enshrined within its legislative corpus the provision for provisional rights under the auspices of 35 U.S.C. § 154(d). This statute manifests as an unparalleled legal contrivance, endowing patentees with the extraordinary capacity to claim reasonable royalties for infringements that transpire during the interstitial period preceding the formal grant of the patent. This legal instrument epitomizes a meticulous balancing act, deftly calibrating the scales of justice to harmonize the vested interests of patent applicants with those of third parties.
The statutory mandate of 35 U.S.C. § 154(d) is replete with nuanced stipulations that necessitate a dual prerequisite: the alleged infringer must have actual notice of the published patent application, and the claims within the granted patent must bear a substantial similarity to those delineated in the published application. This bifurcated criterion serves as a safeguard, ensuring that the patentee’s rights are scrupulously preserved while concurrently mitigating the potential for capricious or unwarranted claims.
The requirement for actual notice is not merely a perfunctory formality but a substantive imperative that necessitates unequivocal evidence that the alleged infringer was apprised of the published patent application. This element of actual notice ensures that the provisional rights bestowed upon the patentee are anchored in a foundation of informed awareness, thereby precluding the spectre of inadvertent infringement.
Furthermore, the criterion of substantial similarity between the published and granted claims is a testament to the statute’s perspicacious design. This provision mandates that the scope of the claims in the granted patent must not deviate egregiously from those initially disclosed in the published application. This requirement serves as a bulwark against the perils of claim broadening that could otherwise ensnare unsuspecting third parties. It ensures that the patent applicant’s entitlement to royalties is predicated on a consistent and transparent delineation of the invention’s scope, thereby fostering an equitable legal milieu.
In sum, 35 U.S.C. § 154(d) stands as a paragon of legislative ingenuity, adeptly balancing the rights and obligations of patent applicants and third parties. By imposing the dual requisites of actual notice and substantial similarity, this statute ensures that provisional rights are conferred in a manner that is both judicious and equitable, thereby fortifying the integrity of the US patent system and its commitment to fostering innovation and protecting intellectual property.

Alternatively, the court acknowledged that actual notice could also be established through compelling evidence that the infringer became aware of the published application by other substantive means, thereby satisfying the statutory mandate.
This judicial exposition served as a clarion call, accentuating the necessity for patentees to exercise diligence in notifying potential infringers. It delineated the contours of actual notice with remarkable precision, thereby fortifying the legal architecture underpinning provisional rights.
- K-TEC, Inc. v. Vita-Mix Corp
In the erudite deliberation of K-TEC, Inc. v. Vita-Mix Corp, the court delved into the intricacies of the ‘substantially identical’ criterion, which serves as a pivotal determinant in the adjudication of provisional rights. The court’s astute analysis reaffirmed that for the claims in a published patent application and those in the granted patent to be considered substantially similar, they must not exhibit significant divergence in their scope.
The court astutely recognized that amendments made during the prosecution of a patent application do not ipso facto preclude the establishment of substantial similarity. It acknowledged that amendments are a natural and oftentimes necessary facet of the patent prosecution process. The critical determinant, as the court elucidated, is whether such amendments engender a material narrowing of the claims’ scope.
By affirming that not all amendments necessarily abrogate substantial similarity, the court provided a nuanced and pragmatic interpretation. It posited that amendments aimed at clarifying the claims or addressing specific objections raised during prosecution could still retain substantial similarity, provided they do not alter the fundamental scope of the invention.
This judicial pronouncement in K-TEC, Inc. v. Vita-Mix Corp served to refine the legal framework governing provisional rights, ensuring that the criterion of substantial similarity is applied with both rigor and fairness. It underscored the importance of maintaining consistency in the scope of patent claims, thereby safeguarding the equitable interests of both patentees and third parties.
In summation, the court’s sagacious exegesis in these landmark cases has significantly enriched the jurisprudential landscape of patent law. The elucidation of ‘actual notice’ in Pandora Jewelry, LLC v. Chamilia, LLC and the explication of ‘substantially identical’ in K-TEC, Inc. v. Vita-Mix Corp have fortified the legal underpinnings of provisional rights, ensuring that they are administered with judicious precision and equitable integrity.

The UK patent law, in its unparalleled sagacity, under Section 69(2) of the Patents Act 1977, extends an avant-garde provision that permits pre-grant infringement actions, thereby bestowing upon patentees an expansive and formidable shield of protection. This legislative magnanimity empowers patentees to initiate legal recourse even prior to the formal grant of the patent, a prerogative that significantly augments the robustness of intellectual property safeguards within the UK jurisdiction.
The jurisprudential fortification of this provision has been incontrovertibly reinforced by the Judicial Committee of the Privy Council in the landmark case of Convoy Collateral v. Broad Idea International [2021] UKPC 24. This seminal ruling exemplifies the judiciary’s resolute commitment to maintaining an equitable balance between the rights of patent applicants and the imperatives of legal adjudication.
In Convoy Collateral v. Broad Idea International, the Privy Council elucidated with crystalline clarity the breadth and profundity of the court’s jurisdiction to grant interim injunctions in the realm of patent law. The court, in its profound wisdom, affirmed that the statutory prohibition against initiating infringement actions prior to the grant of a patent does not, in any measure, curtail the court’s inherent authority to issue interim relief. This judicial pronouncement underscores the adaptability and responsiveness of the legal system to the exigencies of safeguarding patentees’ rights during the critical interim period.
The Privy Council, with its characteristic erudition, posited that the court’s power to grant interim injunctions is not circumscribed by the temporal confines of the patent grant process. Rather, this authority is anchored in the overarching principle of ensuring justice and preventing irreparable harm. The court opined that the issuance of interim injunctions serves as a crucial instrument in preserving the status quo and mitigating potential damages that patentees might incur due to unauthorized exploitation of their innovations.
The decision in Convoy Collateral v. Broad Idea International represents a jurisprudential tour de force, setting a resplendent precedent that amplifies the protective ambit of UK patent law.
