REFUSAL ORDER SET ASIDE FOR LACK OF INVENTIVE STEP ANALYSIS AND VIOLATION OF NATURAL JUSTICE
Statutory Framework: Patents Act, 1970 (Sections 2(1)(ja), 3(k), 117A)
Proceedings: Appeal challenging refusal of patent application
Case: Navya Network Inc. v. Assistant Controller of Patents and Designs
Background and Procedural History
The Appellant, Navya Network Inc., challenged an order of the Patent Office refusing its PCT National Phase patent application bearing No. 2068/MUMNP/2014 titled “Medical Research Retrieval Engine.” The refusal order rejected the application on two grounds: (i) lack of inventive step in view of prior art documents D1–D3 under Section 2(1)(ja) of the Patents Act, and (ii) non-patentability under Section 3(k) as a computer program per se and algorithm.
Aggrieved by the refusal, Navya Network Inc. preferred an appeal before the Bombay High Court under Section 117A of the Patents Act. The principal challenge was directed against the absence of any substantive reasoning in the refusal order and the introduction of a new Section 3(k) objection which had not been communicated at the hearing stage.
Submissions of the Appellant
The Appellant contended that the refusal order merely reproduced Claim 1 and summarily concluded that the invention lacked inventive step without conducting any meaningful analysis of the cited prior art. It was argued that the Controller failed to explain how prior art documents D1–D3 disclosed or rendered obvious the claimed invention.
Reliance was placed on the five-step test for determining inventive step laid down in F. Hoffmann La Roche Ltd. v. Cipla Ltd. and subsequently reaffirmed in Tapas Chatterjee v. Assistant Controller of Patents and Designs. According to the Appellant, the refusal order failed to undertake any feature-wise comparison or explain how a person skilled in the art would arrive at the claimed invention from the cited prior art.
On the Section 3(k) objection, the Appellant argued that the hearing notice only alleged that the claims lacked structural or hardware features and were in the nature of a computer program. However, the final refusal order introduced an entirely new basis, namely that the invention involved a “self-learned ontology” and was therefore a non-technical algorithm. It was submitted that this constituted a material departure from the hearing notice and deprived the Appellant of an opportunity to respond.
The Appellant further argued that the invention addressed technical deficiencies in conventional medical literature databases by improving search relevance, retrieval efficiency, and reducing computational load. It was contended that the claimed invention therefore produced a technical effect and could not be excluded under Section 3(k).
Respondents’ Contentions
The Respondent-Controller defended the refusal order by contending that the claimed invention merely operated on generic hardware and did not improve the internal functioning of a computer or database system. According to the Respondent, the alleged technical effect was limited to generation of a logical expression and did not transcend the statutory exclusion under Section 3(k).
The Respondent further argued that once the invention was found to be a computer program per se or algorithm implemented on generic hardware, the Section 3(k) bar itself was sufficient to sustain refusal without any separate analysis of novelty or inventive step. Reliance was also placed on Blackberry Ltd. v. Controller Patents and Designs.
Court’s Analysis
Failure to Apply the Inventive Step Test
The Court observed that the refusal order failed to undertake the settled analytical framework required for assessing inventive step. While the Controller concluded that the claims lacked inventive step in view of D1–D3, the order did not explain how the cited prior art disclosed the claimed features or rendered the invention obvious.
The Court reiterated that the five-step test articulated in F. Hoffmann La Roche Ltd. v. Cipla Ltd. requires a reasoned examination of:
- The person skilled in the art;
- The inventive concept embodied in the patent;
- The common general knowledge in the field;
- Differences between the prior art and the claimed invention; and
- Whether those differences would have been obvious to a person skilled in the art.
According to the Court, the Patent Office is required to undertake a feature-wise analysis identifying which aspects of the invention are disclosed in the prior art and why such differences would be obvious. A bare conclusion that the invention lacks inventive step cannot substitute for this statutory exercise.
Section 3(k) and Technical Effect
The Court noted that the Appellant had specifically argued that the invention yielded a technical effect through improved database retrieval efficiency and reduced computational burden. The Court held that such contentions required specific examination, particularly in light of evolving jurisprudence concerning computer-related inventions and technical effect under Section 3(k).
However, the refusal order failed to analyse these submissions in any meaningful manner.
Violation of Principles of Natural Justice
A significant defect identified by the Court was the material departure between the hearing notice and the final refusal order. The hearing notice only alleged absence of structural or hardware limitations and categorised the claims as computer programs. In contrast, the refusal order introduced a fresh finding that the invention related to a “self-learned ontology” and was therefore non-technical.
The Court held that these findings travelled beyond the scope of the hearing notice and deprived the Appellant of an opportunity to address the objection. Such departure constituted a violation of the principles of natural justice.
The Court further clarified that even assuming the Controller’s conclusion under Section 3(k) was substantively correct, that would not cure the defects arising from lack of inventive step analysis and procedural unfairness.
Conclusion and Directions
The Bombay High Court set aside the impugned refusal order and remanded the matter to the Patent Office for fresh consideration in accordance with law. The Patent Office was directed to provide the Appellant an opportunity of hearing and thereafter pass a reasoned order dealing with the objections and submissions raised.
The Court also clarified that its observations should not be construed as casting any aspersion on the Patent Office.
Significance
The decision reinforces two important procedural safeguards in patent adjudication. First, refusal orders on inventive step must contain a reasoned, feature-wise analysis applying the settled five-step obviousness framework rather than mere conclusory findings. Second, final refusal orders cannot travel beyond objections communicated to the applicant during prosecution or hearing, as doing so violates principles of natural justice. The ruling therefore underscores that patent refusals, particularly in the context of computer-related inventions under Section 3(k), must adhere to standards of transparency, procedural fairness, and reasoned decision-making.
DELHI HIGH COURT GRANTS PRO TEM SECURITY IN SEP DISPUTE AGAINST XIAOMI
Statutory Framework: Patents Act, 1970; Delhi High Court Rules Governing Patent Suits, 2022
Proceedings: Commercial patent infringement suit concerning Standard Essential Patents (SEPs) and application for pro tem security
Case: Malikie Innovations Ltd. & Anr. v. Xiaomi Corporation & Ors.
Background and Procedural History
The Delhi High Court considered an application seeking pro tem security in a dispute arising out of alleged infringement of cellular Standard Essential Patents (“SEPs”) relating to 4G and 5G technologies.
The Plaintiffs, Malikie Innovations Ltd. and another entity, asserted rights over a portfolio of patents acquired from BlackBerry Limited, including three Indian patents forming the subject matter of the present suit: IN 283303, IN 317530, and IN 335982. The Plaintiffs contended that the Defendants’ Xiaomi, Redmi, and POCO devices implemented technologies covered by the Suit Patents while continuing to operate without a licence despite prolonged FRAND negotiations.
Negotiations between the parties had continued for more than two years, during which licensing offers and counteroffers were exchanged. However, no agreement was ultimately executed. The Plaintiffs thereafter instituted proceedings before the Delhi High Court seeking relief for infringement and moved an application seeking interim financial security pending adjudication of the suit. During the pendency of the proceedings, Xiaomi instituted a FRAND rate-setting action before the Shenzhen Intermediate People’s Court in China. That filing subsequently assumed significance in the Court’s analysis concerning essentiality and implementer conduct.
Submissions of the Parties
Plaintiffs’ Contentions
The Plaintiffs argued that they were the lawful assignees and proprietors of the Suit Patents and were therefore competent to institute the proceedings without impleading BlackBerry as a co-plaintiff. According to the Plaintiffs, Section 109 of the Patents Act applies only where proceedings are instituted by an exclusive licensee independently of the patentee.
On merits, the Plaintiffs contended that Xiaomi had engaged in extensive licensing negotiations without disputing the necessity of obtaining a licence. It was further submitted that claim charts, technical mappings, royalty calculations, and proposals for dispute resolution had been placed before Xiaomi during negotiations.
The Plaintiffs relied upon Xiaomi’s own declarations that its devices complied with 4G and 5G standards and argued that implementation of such standards necessarily implicated use of the Suit Patents. It was also emphasised that Xiaomi failed to disclose any alternative non-infringing implementation despite raising a defence of non-infringement.
The Plaintiffs additionally argued that Xiaomi’s FRAND action before the Shenzhen Court amounted to a prima facie acknowledgment that the Plaintiffs possessed SEP rights requiring licensing on FRAND terms.
Defendants’ Contentions
The Defendants opposed the application on maintainability as well as merits. It was argued that BlackBerry remained a necessary party to the proceedings and that the absence of the original patentee rendered the suit defective.
The Defendants further contended that no judicial determination had yet been rendered concerning the validity, essentiality, or infringement of the Suit Patents. According to Xiaomi, directing security at the interim stage would effectively presume patent validity contrary to the statutory scheme under the Patents Act.
It was also argued that the Plaintiffs had failed to produce comparable Patent License Agreements (“PLAs”), thereby preventing any objective assessment of whether the royalty demands were FRAND-compliant. Xiaomi additionally submitted that the Shenzhen proceedings were confined to Chinese patents and could not be treated as admissions concerning corresponding Indian patents.
Court’s Analysis
Nature of Pro Tem Security in SEP Litigation
The Court reiterated that pro tem security operates differently from interim injunctive relief. While an injunction restrains commercial activity, a pro tem order merely safeguards the SEP holder’s interests pending adjudication and ensures that continued commercial exploitation does not occur without financial accountability.
Relying upon earlier Division Bench decisions concerning SEP enforcement, the Court observed that FRAND obligations are reciprocal in nature. An implementer who continues using standardised technology without accepting a licence or furnishing security derives a commercial advantage over similarly situated market participants who are already paying royalties.
The Court therefore held that the threshold applicable to pro tem security is materially lower than the standard governing interim injunctions.
Maintainability of the Suit
Rejecting Xiaomi’s objection under Section 109 of the Patents Act, the Court held that the provision applies where proceedings are instituted by an exclusive licensee independently of the patentee. Since the Plaintiffs claimed ownership by assignment, there was no requirement to implead BlackBerry as a co-plaintiff.
Comparable Licensing Agreements
The Court also declined to accept Xiaomi’s contention that comparable PLAs were required at the present stage. The Court observed that the proceedings did not concern final determination of FRAND rates and therefore disclosure of third-party agreements was not a precondition for grant of interim financial protection.
The Court additionally noted that Xiaomi itself possessed licences from several SEP holders and was therefore capable of independently assessing the reasonableness of the Plaintiffs’ licensing position.
Essentiality and Xiaomi’s Shenzhen Proceedings
A significant aspect of the judgment concerned Xiaomi’s institution of FRAND proceedings before the Shenzhen Intermediate People’s Court. The Court observed that a party seeking judicial determination of FRAND royalty rates necessarily proceeds on the premise that the underlying patents are essential and capable of licensing.
Accordingly, Xiaomi’s own conduct in initiating the Shenzhen proceedings was treated as prima facie material supporting the Plaintiffs’ case on essentiality. The Court rejected the contention that the proceedings were confined exclusively to Chinese patents and incapable of bearing upon corresponding SEP assertions in India.
Prima Facie Infringement
The Court further noted that the Plaintiffs had produced claim charts and technical material mapping the Suit Patents onto Xiaomi’s devices. Xiaomi’s products were also publicly marketed as compliant with 4G and 5G standards.
Under Rule 3(B)(vi) of the Delhi High Court Rules Governing Patent Suits, 2022, a defendant asserting non-infringement is required to disclose the alternative technology employed. The Court observed that Xiaomi had failed to place any such material on record.
In these circumstances, the Court held that the Plaintiffs had established a prima facie case concerning validity, essentiality, and infringement of the Suit Patents.
Quantum of Security
The Court also considered the enforceability of any eventual decree. Three of the Defendant entities did not possess assets within India, while the Indian subsidiary was already facing substantial proceedings under the Foreign Exchange Management Act, 1999.
Having regard to the competing royalty positions advanced during negotiations, the Court determined the appropriate quantum of interim security at approximately ₹272 crores.
Conclusion and Directions
The Delhi High Court directed the Defendants to furnish security amounting to ₹272 crores either by deposit before the Registrar General or by way of an unconditional bank guarantee issued by an Indian bank within six weeks.
The Court clarified that the order did not constitute a final adjudication on infringement, validity, or FRAND rates. However, the Plaintiffs were held entitled to interim protection pending disposal of the suit. The Court further observed that failure to furnish the directed security would entitle the Plaintiffs to seek further interim relief, including injunctive remedies.
Significance
The decision further develops Indian SEP jurisprudence concerning interim relief and implementer conduct during FRAND negotiations. The ruling reflects a growing judicial emphasis on ensuring that implementers continuing commercial exploitation of standardised technology during litigation do not do so without corresponding financial safeguards.
The judgment is also significant for its treatment of parallel foreign FRAND proceedings as relevant prima facie material in assessing essentiality and licensing obligations in Indian SEP disputes.
DELHI HIGH COURT HOLDS PENDING NBA APPROVAL CANNOT BY ITSELF DEFEAT PATENT RIGHTS
Statutory Framework: Patents Act, 1970; Biological Diversity Act, 2002
Proceedings: Appeal challenging refusal of patent application
Case: Manu Chaudhary v. Controller of Patents and Designs
Background and Procedural History
The Delhi High Court considered a challenge to the refusal of a patent application concerning an oral herbal painkiller composition and its method of preparation. The application claimed a formulation comprising specified herbal ingredients in particular ratios intended to produce synergistic therapeutic efficacy.
During examination, the Patent Office raised objections relating to inventive step and non-patentability under Sections 3(d), 3(e), and 3(p) of the Patents Act. The Applicant responded to the First Examination Report and amended the claims. Following prosecution, the objections were substantially narrowed to issues concerning approval from the National Biodiversity Authority (“NBA”) and the objection under Section 3(p).
The application was ultimately refused under Section 15 of the Patents Act. The refusal order relied principally on the absence of NBA approval, objections under Section 3(p), and certain procedural issues concerning representation during the hearing. Aggrieved by the refusal, the Applicant approached the Delhi High Court.
Submissions of the Parties
Appellant’s Contentions
The Appellant contended that an application seeking NBA approval had already been filed and that the Patent Office had been informed of the same prior to issuance of the impugned order. It was argued that the delay in grant of approval was entirely beyond the Applicant’s control and could not constitute a valid basis for refusal of the patent application.
The Appellant further submitted that the statutory framework under the Biological Diversity Act only requires NBA approval prior to grant of the patent and does not mandate rejection merely because such approval remains pending during examination. According to the Appellant, the Controller ought to have exercised discretion under Section 15 by deferring consideration of the application until the regulatory process was completed.
The Appellant also disputed the findings under Section 3(p) and contended that procedural objections relating to representation could not independently sustain refusal of the application.
Controller’s Contentions
The Controller defended the refusal order by contending that NBA approval ought to have been produced before the passing of the order and that subsequent grant of approval could not cure the defect.
The Respondent further maintained that the application was independently liable to refusal under Section 3(p) of the Patents Act and also relied upon objections concerning the Applicant’s representation during the hearing proceedings.
Court’s Analysis
Requirement of NBA Approval
The Court examined the interplay between the Patents Act and Section 6(1A) of the Biological Diversity Act. It observed that the statutory requirement is that approval from the NBA must exist prior to grant of a patent and not necessarily at the examination stage itself.
The Court noted that the Applicant had already initiated the approval process and had specifically informed the Patent Office of the pending application before the refusal order came to be passed. In these circumstances, the delay in issuance of approval could not be attributed to the Applicant.
A significant aspect of the judgment is the Court’s observation that neither the Patents Act nor the Biological Diversity Act contemplates automatic refusal of a patent application merely because NBA approval remains pending. The Court held that procedural requirements arising from parallel statutory frameworks must be applied in a reasonable manner and cannot operate to defeat substantive rights where the applicant has already taken the necessary steps for compliance.
Exercise of Discretion under Section 15
The Court further observed that Section 15 confers discretion upon the Controller while dealing with objections raised during examination. According to the Court, the appropriate course in the present case would have been to defer the decision until the NBA approval process was completed instead of proceeding directly to refusal.
The Court emphasised that an applicant cannot be prejudiced for administrative delays occurring before another statutory authority, particularly where the applicant has demonstrated bona fide compliance with the applicable requirements.
Patentability Issues Left Open
While setting aside the refusal order, the Court consciously refrained from examining the merits of the objection under Section 3(p). The issue concerning patentability was left open for fresh consideration by the Patent Office in accordance with law.
Conclusion and Directions
The Delhi High Court set aside the impugned refusal order and remanded the matter to the Patent Office for fresh examination. The Controller was directed to reconsider the application after granting the Applicant a fresh hearing and taking into account the NBA approval subsequently obtained.
The Court further clarified that no additional material, apart from the NBA approval, would be permitted to be introduced during reconsideration. The issue of patentability under Section 3(p) was directed to be adjudicated afresh on its own merits. The reconsideration process was directed to be completed within two months.
Significance
The decision clarifies that pending regulatory approvals under the Biological Diversity Act cannot, by themselves, constitute a standalone basis for refusing patent applications where the applicant has already initiated the approval process.
The ruling is also significant for reaffirming that discretionary powers under Section 15 must be exercised reasonably and in a manner that accommodates practical delays arising from parallel statutory procedures. The judgment therefore reinforces procedural fairness in patent prosecution, particularly in cases involving regulatory approvals outside the control of the applicant.
DELHI HIGH COURT REFUSES INTERIM PROTECTION TO ALKEM IN ‘A TO Z’ TRADEMARK DISPUTE
Statutory Framework: Trade Marks Act, 1999; Copyright Act, 1957
Proceedings: Commercial suit alleging trademark infringement, passing off, and copyright infringement
Case: Alkem Laboratories Limited v. Prevego Healthcare and Research Pvt. Ltd.
Background and Procedural History
The dispute before the Delhi High Court concerned competing nutraceutical products marketed under the marks ‘A TO Z’ and ‘MULTIVEIN AZ’.
Alkem Laboratories Limited claimed long-standing use of the ‘A TO Z’ family of marks in relation to multivitamin and multimineral supplements since 1998. The marks formed part of Alkem’s nutraceutical portfolio and were asserted to have acquired substantial market recognition over the years.
Prevego Healthcare and Research Pvt. Ltd. marketed nutraceutical products under the mark ‘MULTIVEIN AZ’, featuring the term ‘MULTIVEIN’ alongside a stylised ‘AZ’ device. Upon discovering the Defendant’s products, Alkem instituted proceedings alleging trademark infringement, passing off, and copyright infringement, and initially obtained an ex parte interim injunction restraining use of the impugned mark.
The matter subsequently came up for consideration on Prevego’s application seeking vacation of the interim injunction.
Submissions of the Parties
Plaintiff’s Contentions
Alkem argued that the ‘A TO Z’ marks had acquired significant goodwill and distinctiveness through continuous and extensive use over more than two decades. It was contended that the marks functioned as source identifiers associated exclusively with Alkem’s products in the pharmaceutical and nutraceutical market.
The Plaintiff further submitted that the Defendant had appropriated the essential and dominant feature of its marks, namely the combination of the letters ‘A’ and ‘Z’, thereby creating a likelihood of consumer confusion and association.
Alkem additionally alleged imitation of its logo structure, visual presentation, and packaging style, giving rise to claims of copyright infringement and passing off.
Defendant’s Contentions
Prevego opposed the injunction primarily on the ground that ‘A TO Z’ is descriptive and incapable of exclusive appropriation in relation to multivitamin products. According to the Defendant, the expression merely conveys completeness or coverage across the full range of vitamins and nutrients.
The Defendant further argued that Alkem’s registrations were limited to stylised device marks and did not confer exclusivity over the constituent letters ‘A’ and ‘Z’ independently. Relying upon Section 17 of the Trade Marks Act, Prevego contended that composite marks must be assessed as a whole and not dissected into isolated components.
It was also submitted that the rival marks, packaging, and overall trade presentation were visually and conceptually distinct. Prevego additionally alleged suppression of material facts by Alkem concerning its own trademark prosecution history in Class 5.
Court’s Analysis
Descriptive Nature of ‘A TO Z’
The Court observed that the expression ‘A TO Z’, when used in relation to multivitamin and nutraceutical products, directly conveys the idea of completeness or comprehensive nutritional coverage. The phrase therefore described the character and intended attributes of the goods rather than identifying their commercial source.
Relying upon settled principles governing descriptive and generic marks, the Court reiterated that expressions which are publici juris cannot ordinarily be monopolised merely on account of prolonged commercial use. The Court found that Alkem had failed, at the interim stage, to establish that the expression had acquired such a strong secondary meaning that consumers exclusively associated ‘A TO Z’ with the Plaintiff alone.
The Court also considered Alkem’s own conduct before the Trade Marks Registry, noting that in earlier proceedings the Plaintiff had acknowledged that protection extended only to the stylised representation of the registered device marks and not to the constituent letters independently.
Anti-Dissection Rule and Deceptive Similarity
Applying the anti-dissection principle embodied in Section 17 of the Trade Marks Act, the Court held that the competing marks were required to be assessed in their entirety and not by isolating selected components.
The Court rejected Alkem’s attempt to compare only the ‘A’ and ‘Z’ elements of the marks. When viewed holistically, the Court found the rival marks to be visually, phonetically, and conceptually distinct. The presence of the word ‘MULTIVEIN’ materially altered the overall commercial impression of the Defendant’s mark, while the packaging, colour combinations, typography, and layout of the competing products were also found to be different.
The Court therefore concluded that the test for deceptive similarity was not satisfied.
Copyright and Trade Dress Claims
The Court further held that copyright protection in a stylised artistic logo does not extend to a monopoly over individual alphabetic characters forming part of the design. Upon comparison of the rival labels and logos, the Court found no substantial similarity capable of sustaining a copyright claim.
Similarly, the trade dress allegations were rejected on the ground that the competing products conveyed sufficiently different visual impressions in terms of packaging, colour palette, and presentation.
Suppression of Material Facts
A significant factor weighing against grant of equitable relief was the Plaintiff’s failure to disclose certain prior trademark applications and proceedings relating to the ‘A TO Z’ marks in Class 5. The Court observed that a party seeking discretionary interim relief is under an obligation to place all material facts before the Court.
The omission was treated as a relevant circumstance disentitling the Plaintiff from equitable protection at the interim stage.
Conclusion and Directions
The Delhi High Court vacated the earlier ex parte injunction granted in favour of Alkem and dismissed the application seeking interim relief. The Court held that the Plaintiff had failed to establish a prima facie case of trademark infringement, passing off, or copyright infringement against Prevego.
Significance
The decision reinforces the principle that commercial success and long-standing use cannot, by themselves, convert a descriptive expression into an enforceable monopoly absent clear evidence of acquired distinctiveness.
The ruling also reiterates the importance of the anti-dissection rule in trademark analysis, particularly in cases involving composite device marks. Equally significant is the Court’s emphasis that parties seeking interim equitable relief must make full and candid disclosure of their trademark prosecution history and related proceedings.
BOMBAY HIGH COURT REFUSES INTERIM RELIEF IN ATOMBERG FAN DESIGN DISPUTE
Statutory Framework: Designs Act, 2000
Proceedings: Commercial IP suit alleging design infringement and passing off
Case: Atomberg Technologies Private Limited v Stove Kraft Limited
Background and Procedural History
The Bombay High Court considered an interim application arising from a design infringement action concerning ceiling fans.
The Plaintiff, Atomberg Technologies Private Limited, claimed rights in a registered design relating to its “Renesa Alpha” ceiling fan and alleged that the Defendant’s “Pigeon Fan-tastic BLDC Ceiling Fan” constituted a fraudulent imitation of the registered design. Interim relief had earlier been granted restraining the Defendant from dealing in the impugned product. The Defendant subsequently sought vacation of the interim order.
The dispute formed part of a broader series of proceedings initiated by the Plaintiff concerning various “Renesa” fan models. The Defendant relied upon prior proceedings where interim protection concerning another Renesa design had already been declined on grounds relating to absence of novelty and originality.
Submissions of the Parties
Plaintiff’s Contentions
The Plaintiff argued that the suit fan embodied a novel and distinctive design characterised by unique visual features relating to the blade configuration, shank profile, canopy structure, and motor housing. According to the Plaintiff, the Defendant’s fan reproduced the essential visual features of the registered design and amounted to piracy under the Designs Act.
The Plaintiff further contended that the Defendant itself had applied for registration of its fan design, which according to the Plaintiff constituted an acknowledgment that the design possessed distinctiveness and originality. Reliance was also placed on earlier orders granting interim protection against third parties in relation to similar products.
On passing off, the Plaintiff asserted substantial goodwill and market recognition in relation to the Renesa range of ceiling fans.
Defendant’s Contentions
The Defendant challenged both infringement and validity of the Plaintiff’s registration. It was argued that the Plaintiff had improperly compared the impugned fan not with the actual registered design, but with subsequent variants and later commercial models introduced by the Plaintiff.
According to the Defendant, the suit design lacked novelty and merely constituted a trade variant of pre-existing ceiling fan designs already available in the market. The Defendant emphasised that basic elements such as blades, canopy structures, motor housings, and shank configurations are inherent to any ceiling fan and cannot independently constitute novelty under the Designs Act.
The Defendant further contended that the allegedly distinctive “Z-shaped” shank feature prominently relied upon by the Plaintiff was absent in the impugned fan. Various visual distinctions were highlighted concerning blade curvature, rivet placement, canopy structure, motor housing configuration, and overall visual appearance.
The Defendant also disputed the Plaintiff’s passing off claim, arguing that no material had been produced to establish distinctiveness or goodwill specifically associated with the registered design itself.
Court’s Analysis
Comparison Must Be with the Registered Design
A significant aspect of the judgment concerns the Court’s criticism of the comparative analysis adopted by the Plaintiff. Upon examining the comparative tables placed on record, the Court observed that the Plaintiff had not confined its comparison to the registered design forming the subject matter of the suit. Instead, the Plaintiff compared the Defendant’s product with subsequent commercial models introduced after the registration.
The Court noted that the Plaintiff had launched several variants within the Renesa product line over time and appeared to rely upon those later models to highlight alleged similarities with the Defendant’s fan. Prima facie, this amounted to a product-versus-product comparison rather than a comparison between the impugned article and the actual registered design.
Novelty and Originality under the Designs Act
The Court reiterated that protection under the Designs Act extends only to novel visual features capable of distinguishing the registered design from ordinary articles already available in the market. Basic functional attributes inherent to a ceiling fan cannot themselves constitute novelty.
The Court observed that ordinary features such as blades, canopies, motor housings, and shank structures are common to all ceiling fans and therefore cannot independently sustain a claim for infringement absent demonstrable originality in visual appearance.
Upon comparison of the rival products, the Court found no obvious similarity in the features specifically claimed as novel by the Plaintiff. In particular, the Court noted that the distinctive curved blade structure and “Z-shaped” shank configuration relied upon by the Plaintiff were not present in the Defendant’s product.
Visual Test in Design Infringement
Reaffirming settled principles governing design piracy, the Court observed that similarity in design cases is judged solely by the eye. The inquiry is whether the impugned article, viewed as a whole, creates an overall visual impression amounting to imitation of the registered design.
Applying this standard, the Court held that the rival fans were visually distinguishable in terms of blade profile, motor housing lid, canopy structure, rivet placement, and shank configuration. Even when the physical products were produced before the Court, no visual similarity sufficient to establish piracy was found.
Passing Off Claim
The Court also rejected the passing off claim. It observed that a claim founded on passing off in design matters requires “something more” than mere similarity of products. The Plaintiff failed to establish that the registered design had independently acquired such goodwill or distinctiveness that consumers associated the specific get-up exclusively with the Plaintiff.
The Court further noted that the sales and promotional material relied upon by the Plaintiff related collectively to multiple fan models and not specifically to the suit design forming the subject matter of the proceedings.
Conclusion and Directions
The Bombay High Court held that the Plaintiff failed to establish a prima facie case of design infringement or passing off. The Court accordingly dismissed the interim application and vacated the earlier interim protection granted in favour of the Plaintiff. The Court Receiver appointed earlier in the proceedings was discharged, and the seized goods were directed to be released to the Defendant.
Significance
The decision reiterates that infringement analysis under the Designs Act must remain confined to the registered design itself and cannot be expanded through comparisons with later commercial variants or modified product lines. The ruling also reinforces the narrow scope of design protection in relation to functional consumer products, particularly where alleged novelty rests upon features commonly present within the industry. Equally significant is the Court’s emphasis that passing off claims in design disputes require proof of distinctiveness beyond mere visual similarity.
