Maintainability of Letters Patent Appeal against Judgment passed by High Court in a Trademark Rectification Petition
Introduction:
The issue of maintainability of Letters Patent Appeal (LPA) against a judgment passed by the High Court in a Trademark Rectification Petition has been a matter of contention. This article analyzes the recent case post Resilient Innovations Pvt. Ltd. Vs Phonepe Private Limited & Anr [2023:DHC:3426-DB] and subsequent developments that affirm the maintainability of such appeals.
Background:
The case in question involved the dismissal of a rectification petition of a trademark by a Single Judge of the Delhi High Court. The respondent challenged the judgment by contending that the earlier decision of the Delhi High Court in Resilient Innovations Pvt. Ltd. Vs Phonepe Private Limited & Anr did not consider the scope of Limitation put by Section 13 of the Commercial Court Act 2015 to Appeals, particularly with reference to Letters Patent Appeal.
Resilient Innovations Pvt. Ltd. Vs Phonepe Private Limited & Anr:
In Resilient Innovations Pvt. Ltd. Vs Phonepe Private Limited & Anr, the Delhi High Court answered the issue of maintainability of an LPA against a judgment passed by the High Court in a rectification petition, in affirmative. However, the respondent argued that this judgment failed to consider the provisions of Section 13 of the Commercial Court Act 2015, which seemingly restricts any other intra-Court appeal, beyond the provision of Order 43 CPC.
The Hon'ble High Court's Ruling:
The Hon'ble Division Bench of the Delhi High Court, in the present case, reaffirmed its earlier judgment in Resilient Innovations Pvt. Ltd. Vs Phonepe Private Limited & Anr and held that an LPA against the judgment of a Single Judge in a Trademark Rectification Petition is maintainable, albeit supplementing with reasoning , as left out in Resilient Judgement.
Reasoning:
The Division Bench elucidated that the bar under Section 13 of the Commercial Court Act 2015 does not apply to judgments passed by Single Judges of the High Court in a Rectification Petition under Section 57 of Trade Marks Act 1999[ TMA].
The rationale behind this conclusion lies in the nature of jurisdiction exercised by a Judge in the Commercial Division while entertaining a petition under Section 57 of TMA. Section 57 enables any aggrieved person to seek cancellation or variation of a registered trademark before the High Court or the Registrar.
The power vested in the High Court under Section 57 is a specific authority conferred by the TMA and not derived from its existing ordinary original civil jurisdiction. Hence, when the High Court entertains a petition under Section 57, it does so solely through the avenue created by the TMA, rather than its general civil jurisdiction.
Furthermore, the Court referred to Section 13(1A) of the 2015 Act, which specifically mentions a judgment or order rendered by a commercial court exercising "original civil jurisdiction." Since the power exercised by the Commercial Division under Section 57 is not traceable to its original jurisdiction, appeals against judgments or orders not arising from the exercise of original jurisdiction would not be governed by Section 13 of the 2015 Act.
The Concluding Note:
The Hon'ble Division Bench of the Delhi High Court, through its reaffirmation of the earlier judgment in Resilient Innovations Pvt. Ltd. Vs Phonepe Private Limited & Anr, has clarified the maintainability of Letters Patent Appeals against judgments passed by the High Court in Trademark Rectification Petitions. The Court's reasoning underscores the distinction between the jurisdiction exercised under Section 57 of the TMA and the general civil jurisdiction of the Commercial Division, thus confirming the viability of such Letters Patent appeals.

Intention to Use an Expression as a Descriptor is Immaterial if it Actually Results in Confusion
Introduction:
In this legal article, we delve into a case where the plaintiff claimed to be the registered proprietor of the marks "MADHUR" and "MADHUR MADHUR GULAB" written in devanagari script. The subject matter of the suit was filed against the defendant's use of the trademark "MANGALDEEP MADHUR."
The defendant argued that they use the expression "MANGALDEEP MADHUR" not as a trademark but merely to describe their product and its characteristics.
However, the court rejected this contention and restrained the defendant, emphasizing that even if the intention to use the mark as a trademark was absent, infringement could still occur if confusion resulted.
The Court's Decision:
The Court observed that the intention to use a mark as a trademark is not the sole determinant of infringement. Under section 29(1) and section (2)(zb)(ii) of the Trade Marks Act, a registered trademark is infringed if it is used in a manner likely to be taken as a trademark, regardless of the user's intent.
Trademark Infringement and Connection in the Course of Trade:
The court pointed out that the use of a registered trademark would constitute infringement if it indicates a connection in the course of trade between the person and their goods or services, irrespective of their intention. The crucial factor here is whether the use of the mark creates a likelihood of confusion among consumers, leading them to believe there is a connection between the defendant's goods and the registered proprietor's goods.
Descriptive Sub-Brands and Confusion:
The defendant argued that their products were sold under the umbrella brand "MANGALDEEP" and that the descriptors such as "MADHUR" and "MADHUR 100" were used to signify the quality and characteristics of the product.
However, the court rejected this argument, stating that even if the defendant genuinely intended to use the mark only as a description of the product's aroma, it would not make any difference if the use of the mark was likely to be taken as a trademark.
The Concluding Note:
This case sets a precedent that the intention to use an expression as a descriptor is immaterial if it actually results in confusion among consumers, leading them to believe that the expression is being used as a trademark.
It reinforces the need for businesses to exercise caution while using marks, especially when they are similar to registered trademarks, to avoid potential infringement claims. As the court highlighted, the use of a registered trademark would still be considered an infringement if it indicates a connection in the course of trade, irrespective of the user's intention.

V Guard Industries Ltd Vs Crompton Greaves Consumer Electricals Ltd
Introduction:
This article discusses a legal case involving the use of a house mark as a prefix with another trademark and its potential implications for trademark infringement.
The case revolves around a plaintiff who claimed ownership of the trademark "PEBBLE" and filed a suit against a defendant using the trademark "CROMPTON PEBBLE" for dry irons.
The defendant argued that the use of the house mark "CROMPTON" distinguished its products from the plaintiff's, but the court rejected this defense and restrained the defendant from using the trademark "PEBBLE."
Background:
The plaintiff was the registered proprietor of the trademark "PEBBLE" under no. 2503134 in Class 11 for water heaters, electric water heaters, heating coils, electric water geysers, etc. The defendant was using the trademark "CROMPTON PEBBLE" in relation to dry irons, which the plaintiff alleged to infringe upon their registered trademark.
Defendant's Defense:
The defendant argued that there would be no confusion among the public since they were using "CROMPTON PEBBLE" and not "PEBBLE" for dry irons, which were not sold by the plaintiff.
They contended that their products were known for their quality and were sold in the market with various product identification marks associated with the house mark "CROMPTON."
The defendant further asserted that the plaintiff could not claim exclusive rights to the word "PEBBLE" and, therefore, could not allege infringement against "CROMPTON PEBBLE."
Court's Ruling:
The court rejected the defendant's contentions by observing that the Trade Marks Act does not recognize the concept of subbranding.
In cases of infringement involving label or word marks, the test for infringement is based on the prominent word of the mark.
Therefore, adopting a prominent word from the plaintiff's label/device mark, as the defendant did with "PEBBLE," constitutes infringement.
In this case, "PEBBLE" was an essential part of the plaintiff's registered trademark, and the defendant could not argue for exclusive use of the word based on registration.
Additionally, the court noted that the defendant had consistently used the mark "PEBBLE" with its house mark "CROMPTON" as a source identifier for its products.
The plaintiff had been using the registered mark/label with the dominant part being the word "PEBBLE" since 2013.
The defendant's lack of a plausible explanation for adopting the word "PEBBLE" in conjunction with "CROMPTON" further strengthened the court's decision.
The Concluding Note:
In light of the court's observations, the defendant was restrained from using the trademark "PEBBLE."
The case highlights the importance of not using prominent words from other trademarks as part of a new trademark, even if a house mark is used as a prefix.

The Static and Dynamic Effect of Patent and Territorial Jurisdiction of High Courts with Respect to Patent Appeal and Patent Revocation
Abstract:
This analytical legal article explores the territorial jurisdiction of High Courts concerning patent revocation and patent appeals after the abolition of the IPAB (Intellectual Property Appellate Board). It examines two scenarios involving different High Courts and patent applications filed in different locations.
The article analyzes the concept of territorial jurisdiction under the 1970 Act, focusing on the static and dynamic effects of patent grants and their impact on commercial interests. The discussion revolves around the relevant considerations for determining the High Court's territorial jurisdiction in patent-related matters.
Introduction:
The territorial jurisdiction of High Courts plays a crucial role in patent revocation and appeal cases. This article delves into the complexities arising after the IPAB's abolition and how the jurisdiction is determined in two distinct scenarios: Patent Revocation and Patent Appeal.
Territorial Jurisdiction in Patent Revocation:
In cases of patent revocation, the High Court's territorial jurisdiction is determined based on both the static and dynamic effects of the patent grant. The High Court in the jurisdiction where the patent was granted would naturally be one of the fora with jurisdiction. However, considering the dynamic effect, the commercial interests of the petitioner, who may be affected in various jurisdictions, can influence other High Courts' jurisdiction. Such High Courts may entertain revocation petitions under section 64 of the Act. The cause of action consists of a series of events starting with the grant of the patent, and thus, the territorial jurisdiction for revocation petitions should be decided based on the impact on the applicant's commercial interests.
Territorial Jurisdiction in Patent Appeal:
In the case of patent appeals, the jurisdiction is determined by the High Court having territorial jurisdiction over the appropriate office from where the patent application originates and which is the situs of the said application. Appeals challenging the order or direction of the Patent Office under Section 117A of the 1970 Act lie before the High Court with territorial jurisdiction over the relevant patent office. The concept of cause of action cannot be pleaded to vest jurisdiction in other High Courts, i.e., other than the one where the appropriate office is located.
Concluding Note:
The determination of territorial jurisdiction of High Courts in patent revocation cases post abolition of the IPAB involves considering both the static and dynamic effects of the patent grant. While the High Court where the patent was granted holds primary jurisdiction, other High Courts may also have jurisdiction based on the petitioner's commercial interests and the impact of the patent in different locations. On the other hand, patent appeals are limited to the High Court within the territorial jurisdiction of the appropriate patent office.

Jurisdictional Impact of IPAB Abolition on Trademark Suit
Introduction
This article examines the implications of the abolition of the Intellectual Property Appellate Board (IPAB) and the subsequent vesting of powers to entertain cancellation petitions with the High Courts, specifically in the context of a trademark suit.
The case under discussion involves the trademark "HAIR SPA," where the Plaintiff has filed a suit for trademark infringement, while the Defendant has filed a cancellation petition against the registered trademark of the Plaintiff.
The Hon'ble High Court of Delhi, faced with the Defendant's request for a stay on the suit proceedings due to the invalidity issue being framed, rendered a significant decision regarding the interplay of the suit and cancellation proceedings.
Background
The Plaintiff filed a trademark suit in relation to the trademark "HAIR SPA," asserting its exclusive rights over the mark. Simultaneously, the Defendant filed a cancellation petition, challenging the validity of the Plaintiff's registered trademark. Both matters were brought before the Hon'ble High Court of Delhi.
Defendant's Request for Stay
During the process of framing issues in the case, the Defendant insisted on framing an issue regarding the invalidity of the Plaintiff's registered trademark and requested a stay on the suit proceedings until the cancellation petition was resolved. The Defendant's argument was based on the premise that if the registered trademark is found to be invalid, the suit for trademark infringement would become redundant.
Court's Decision
The Hon'ble High Court of Delhi acceded to the Defendant's request and framed an issue regarding the invalidity of the Plaintiff's registered trademark. However, contrary to the Defendant's request for a stay, the Court declined to halt the suit proceedings. The Court reasoned that the recent Tribunal Reforms Act, 2021, abolished the IPAB and transferred jurisdiction for cancellation or rectification of trademarks to the High Courts. Given this change, the Court found it appropriate not to stay the suit proceedings.
The Court further justified its decision by highlighting that the issues for determination in both the suit and the rectification petition were likely to overlap and be common. Consolidating both proceedings under Rule 26 of the IPD Rules, the Court aimed to streamline the litigation process and ensure efficient resolution of the case.
Impact of IPAB Abolition
The abolition of the IPAB and the subsequent vesting of jurisdiction in the High Courts for cancellation or rectification of trademarks mark a significant shift in the trademark dispute resolution landscape. Traditionally, the IPAB served as the specialized body to handle such matters, but with its dissolution, High Courts now assume these responsibilities.
This change has had practical implications for the case under discussion. By consolidating the suit and the cancellation petition proceedings, the Hon'ble High Court of Delhi sought to avoid potential conflicts, prevent contradictory decisions, and streamline the adjudication process. It demonstrated the Court's readiness to take on the IPAB's former role and effectively handle trademark disputes.
Concluding Note
This case of "HAIR SPA" highlights the jurisdictional impact of the IPAB's abolition and the transfer of powers to the High Courts for handling trademark cancellation and rectification matters. The decision of the Hon'ble High Court of Delhi to frame the issue regarding the invalidity of the Plaintiff's registered trademark while refusing to stay the suit proceedings reflects a proactive approach in light of the recent legal changes. Consolidating both proceedings further indicates the Court's commitment to efficiently adjudicate trademark disputes.

Evaluating Inventive Step in Patent Applications:
Abstract:
This article analyzes the criteria required to be taken into consideration by the Controller of Patent while assessing the patentability of a patent application concerning inventive step.
It discusses a specific case where a patent application was rejected, but later appealed successfully based on the principles established by the Hon'ble Supreme Court of India and the case of Agriboard International LLC vs Deputy Controller of Patents.
The article highlights the importance of analyzing existing knowledge, distinguishing prior art, and considering experimental evidence to determine inventive step in accordance with Section 2(1)(ja) of the Patents Act 1970.
Introduction:
The grant of a patent is subject to several criteria, one of the most crucial being inventive step. This article discusses the legal aspects surrounding the patent application rejection and subsequent appeal related to the inventive step of the subject matter.
Background of the Case:
The subject matter of the patent application in question involves a stereospecific synthesis of (R)-5(E)-2-pyrrolidin-3ylvinyl)pyrimidine, its salt forms, and novel polymorphic forms of these salts.
The invention also includes methods for treating various medical conditions and disorders. The Controller of Patents rejected the patent application citing prior art documents D1, D2, and D3 under sections 2(1)(ja) and 3(d) of the Patents Act 1970.
Criteria for Assessing Inventive Step:
According to the Agriboard International LLC vs Deputy Controller of Patents case, while evaluating the inventive step, the Controller must consider three key elements:
Existing Knowledge: The Controller must identify the relevant prior art, which includes all publicly available information and documents that were accessible before the filing date of the patent application.
Invention Disclosed in the Application: The Controller should thoroughly analyze the invention as disclosed in the patent application under consideration.
Obviousness to a Skilled Person: The Controller needs to assess whether the subject invention would be obvious to a person skilled in the relevant field of art.
The Role of Enhanced Efficacy:
The Appellant contended that the Controller did not discuss the aspect of enhanced efficacy, which could have been crucial in demonstrating non-obviousness.
In support of this argument, the Appellant relied upon the judgment of the Hon'ble Supreme Court of India in Novartis AG vs Union of India (2013) 6 SCC 1.
Analysis of the Hon'ble Court's Decision:
The Hon'ble Court observed that the Controller's order lacked discussion on how the Appellant sought to distinguish D1, one of the cited prior art documents, from the subject invention. The Appellant had pointed out the disadvantages of D1 as prior art, but the Controller failed to address this aspect in the rejection order.
Importance of Experimental Evidence:
Another ground for allowing the appeal was the Appellant's submission of detailed experiments, comparative studies, and conclusive results in support of the claimed invention, which were discussed in Appendix A, B, and C. The Hon'ble Court noted that these crucial pieces of evidence should have been duly considered before passing the rejection order.
Concluding Note:
While assessing the patentability of a patent application with respect to inventive step, the Controller of Patent must consider existing knowledge, distinguish the invention from prior art, and analyze the obviousness to a skilled person.
Furthermore, any aspect of enhanced efficacy or experimental evidence supporting the claimed invention should be given due consideration.
The case discussed in this article serves as a significant reminder to the patent examiners and applicants about the importance of a comprehensive and well-reasoned analysis when evaluating inventive step under the Patents Act 1970.

Qualcomm Incorporated Vs Controller of Patent
Fate of non reasoned Order Passed by the Controller of Patents: The Scope of Interference by High Court
Introduction
This analytical legal article delves into the fate of an order passed by the Controller of Patents, which was challenged in the High Court of Delhi through an appeal filed under Section 117A of the Patents Act, 1970. The appeal sought to challenge the rejection of a patent application filed by the appellant for an invention titled "Minimizing feedback by sending a quality indicator for a nonrestrictive reuse set and a vectored quality indicator for other reuse sets." The crux of the appeal lies in the Controller's failure to address the submissions made by the appellant during the patent examination process.
Background
The patent application in question (no. 5159/DELNP/2007) was filed on 4 July 2007. Subsequently, the Patent Office raised objections to the application, prompting the appellant to submit responses to these objections on 19 December 2012. A hearing was granted to the appellant on 3 December 2014. However, despite the appellant's submissions and the hearing, the Deputy Controller of Patents and Designs passed an order on 31 October 2016 rejecting the patent application.
The pivotal issue raised in the appeal before the High Court of Delhi was the lack of proper reasoning in the Controller's order. The order acknowledged the receipt of responses from the appellant but failed to address the contents of these submissions. Notably, there was no indication that the Controller examined the merits of the appellant's responses or engaged with the arguments put forth.
Furthermore, the order revealed that the Deputy Controller concurred with the findings of the Examiner, yet no reasons were provided for this agreement. Additionally, the order did not make any observations or findings regarding the appellant's response to the Examiner's objections. This deficiency led to a manifest non-application of mind on the part of the Controller and rendered the order ex facie unreasoned.
High Court's Ruling
Upon hearing the appeal, the Hon'ble High Court of Delhi took a critical stance on the Controller's order. The court observed that an order that fails to address the submissions made by the party challenging the decision suffers from a fundamental flaw manifest non-application of mind. In other words, when an authority adjudicating a matter overlooks or ignores crucial submissions by a party, it indicates that the decision-making process was flawed.
The court went on to emphasize that such an inadequately reasoned order cannot stand either in law or on facts. It not only violates the principles of natural justice, which dictate that parties be given a fair opportunity to be heard and that their submissions be duly considered, but also undermines the efficacy of the patent system.
Patent examination and grant procedures necessitate meticulous scrutiny of the application and the arguments presented, and the absence of proper reasoning can lead to arbitrary and unjust decisions.
Conclusion
In conclusion, the fate of an order passed by the Controller of Patents, when it fails to address the submissions made by the appellant, is likely to be set aside and remanded for de novo adjudication.
The case at hand exemplifies the importance of reasoned decision-making and the application of mind by the patent authorities. The High Court of Delhi's ruling sends a strong message that orders lacking proper reasoning and non-consideration of submissions will not be tolerated.
The judgment highlights the significance of transparency, accountability, and adherence to principles of natural justice in the patent examination process. Patent applicants are entitled to fair treatment and a thorough assessment of their claims.
Consequently authorities responsible for adjudicating patent matters must ensure that their orders are reasoned, well-grounded, and take into account all relevant submissions before rendering a decision. Failure to do so can result in the invalidation of the order and the need for reevaluation.

Analyzing Product-by-Process Claims in a Suit for Patent Infringement:
Abstract:
This legal article delves into the dispute brought before the Hon'ble High Court of Delhi in a patent infringement suit, where the primary issue revolves around the scope of the plaintiff's rights in a product-by-process claim. The plaintiff contended that the patent claim was a product claim, while the defendant argued that the scope of the claim was limited to the process disclosed in the patent. The court's analysis and findings in this case shed light on the significance of process features in product-by-process claims and the implications for patent protection.
Introduction:
In the subject matter suit for patent infringement before the Hon'ble High Court of Delhi, the central dispute pertained to the nature and scope of a patent claim relating to water-soluble iron carbohydrate complexes used in the formulation of a medical product known as FCM (Ferric Carboxymaltose). The plaintiff asserted that Claim 1 of the patent was a product claim, while the defendant contended that it was a product-by-process claim, limiting the plaintiff's rights to the specific process disclosed in the patent.
Product-by-Process Claims:
A product-by-process claim is a type of patent claim that defines a product based on the process by which it is made rather than its structural features. These claims are frequently used when the product itself cannot be fully described or characterized by its physical properties alone, and the process used to create it is essential to its unique properties. In such cases, the patent claim may specify the process steps required to manufacture the product, making it necessary for any potential infringer to use the same process to be liable for infringement.
Court's Analysis and Findings:
The Hon'ble High Court of Delhi analyzed the language of Claim 1 of the patent (IN’221536) and reviewed the complete specification and prosecution history to determine the scope of the claim. The court observed that the patent itself admitted that iron carbohydrate complexes were already known, and the invention's novelty lay in using maltodextrin as the starting material and oxidizing it with an aqueous hypochlorite solution to produce FCM.
Prosecution History Estoppel:
The principle of prosecution history estoppel holds that a patentee cannot make inconsistent statements during the patent application process, claiming certain properties are solely due to the process, and later assert broader claims that encompass other processes or products. In this case, the plaintiff's admission regarding the significance of the process features in obtaining the unique properties of FCM led the court to limit the scope of the claim accordingly.
The Defendant's submission in February 2020, opposing a third party's patent application (No. 3474/CHE/2013), further strengthens the Plaintiff's admission. In their opposition, the Plaintiff mentioned at multiple instances that Claim 1 of IN’536 relates to a process claim.
The Court, while evaluating infringement in a process by product patent, focuses on the process as a limiting factor. Typically, infringement is deemed to occur only when a product is made using the same process as claimed in the patent. Consequently, if the Defendants can successfully demonstrate that their product FCM is manufactured using a different process, they cannot be accused of infringement.
Analyzing Claim-1 in IN’536, it becomes evident that the claim covers water-soluble iron carbohydrate complexes obtained from an aqueous solution of iron (III) salt and an aqueous solution of the oxidation product of one or more maltodextrins using an aqueous hypochlorite solution at an alkaline pH. On the other hand, the Defendants' process for obtaining FCM involves using hydrolyzed starch treated with an appropriate acid medium in an acidic pH, followed by heating to create a mixture of hydrolyzed starch.
Based on this analysis, the Court observed that, at a prima facie stage, the Defendants have successfully established that their process for obtaining FCM falls outside the scope of IN’536. As a result, the Court held that the impugned process of CRPL and VBPL (Defendants) is non-infringing.
Plaintiff' Reliance on interim order passed in different Suit is merely persuasive:
The Plaintiff argued that various interim orders issued by different Courts regarding FCM demonstrated the strength of IN’536. They urged the Court to maintain uniformity in judicial decisions by granting an injunction against the Defendants. However, this argument was not accepted by the Court, being merely persuasive in nature.
Conclusion:
The case before the Hon'ble High Court of Delhi highlights the importance of product-by-process claims in patent law. Patent protection secured through such claims is limited by the process used to create the product, and a monopoly cannot be claimed over the product as a whole. The court's analysis and findings provide valuable insights into the scope of product-by-process claims and the significance of prosecution history estoppel in determining patent infringement case
