Claim 14 discloses the process for preparation of composition, as claimed in Claim 1. 5.[6] Purpose of the Suit Patent, which is a formulation with natural ingredients, is not limited to reducing the side effects caused by the iron supplements but to also maintain Iron homeostasis by hepcidin regulation and hence, will provide a natural treatment for IDA and AOI. 5.[7] In line of the mandate of Section 83 of the Patents Act, 1970 [‘Act of 1970’], the Plaintiffs have commercialised the product claimed via the Suit Patent since June of 2018. The Plaintiff’s first commercial product was launched in June, 2018 incorporating the claimed subject matter of IN’949 under the brand name FERRONOMIC. The FERRONOMIC contains 100 mg Lactoferrin and 10 mg of Disodium Guanosine 5-Monophosphate. 5.[8] Further, the Plaintiffs have developed various products incorporating the claimed subject matter of IN’949.

On 16.07.2025, the Plaintiffs learnt the presence of Defendants’ product ‘FERROTOK PLUS’ [‘impugned product’ or ‘infringing product’] in the market through its representatives. 6.[1] It is stated that Defendant Nos. 1 and 2 are the manufacturers and Defendant Nos. 3 and 4 are the ex-employees of Plaintiff No. 2, who are employed with Defendant No. 1. Defendant Nos. 3 and 4 possibly hold senior management positions with Defendant No. 1. 6.[2] It is stated that Defendant Nos. 1 and 2’s product is available in the market. And, from the information on the package of the infringing product, Plaintiffs found the ingredients used therein clearly match the claims of the Suit Patent. According to the outer-package, the Defendant’s product contains Lactoferrin 50 mg (6.0%*), Disodium Guanosine 5-Monophosphate - 5 mg and Elemental Iron [as Ferrous Bisglycinate] 27mg.

The intent of the Defendants is to mislead the general public into believing the website belong to the Plaintiffs and to ensnare the public including stockists and retailers into dealing with the Defendants for the infringing products. 6.[7] It is further alarming to note that the infringing products are supposed to be used by pregnant anaemic women and if the said products are substandard, the same might even cause harm to the general public. 6.[8] On further research, the Plaintiffs obtained invoices of the Defendant’s infringing product showing that the said product is being sold in many parts of India.
CASE SETUP BY THE DEFENDANT IN REPLY
7. The Plaintiffs were directed to effect advance service on Defendant Nos. 1 to 4. Mr. Santosh Kumar, Advocate entered appearance on behalf of Defendant Nos. 1 to 4 on 11.08.2025 and sought an adjournment to address arguments. The matter was taken up on 14.08.2025, when Mr. Santosh Kumar, Advocate stated that he will address arguments on behalf of Defendant No. 1, 3 and 4. He stated that Defendant No. 2 has not given him instructions to address arguments though Defendant No. 2 is aware about the hearing scheduled on 14.08.2025.
8. Mr. Santosh Kumar, learned counsel representing the Defendant Nos. 1, 3 and 4 made the following submissions: - 8.[1] The First Examination Report [‘FER’] dated 13.02.2020[2] issued by the Indian Patent Office, while prosecuting the Suit Patent, stated that Claims 1 to 17 of the complete specification of the Suit Patent lack novelty and inventive step in light of prior art, and the Controller rejected the subject matter of the Suit Patent. 8.[2] Amended Claims 1 to 15 were filed on 24.05.2021 by the Plaintiffs as stated in the Assistant Controller’s orders, but the same is not on record. It was stated that the granted claims of Suit Patent as filed with the affidavit dated 08.08.2025 before this Court bears the date of 09.03.2018 and not 24.05.2021. 8.[3] It was contended that the Plaintiffs have not filed a certified copy of the Complete Specification; therefore, reliance cannot be placed on the downloaded copy from the IP India Website. 8.[4] There are approximately 30 to 40 different products with a similar chemical composition to that of the Defendant’s patent readily available in the market. Thus, it is a commonly available formula. Filed as Document No. 14 in Plaintiff’s Document. 8.[5] Claim 1 of IN’949 states the range of Lactoferrin between 5 to 90% by weight of the composition. However, the Plaintiffs’ contention that the Defendants’ tablet contains 6% Lactoferrin is based on an in-house report. However, the same could possibly fall outside the claimed range and therefore the said report is not admitted. 8.[6] Defendant No. 1, being a distributor, is not able to provide the details of the composition used for manufacturing the impugned product. The information regarding same is only available with Defendant No. 2, who is the manufacturer of the product and is manufacturing similar products for third parties. 8.[7] The Defendant Nos. 1, 3 and 4 were granted liberty to file written submissions, which has been filed on 21.08.2025. In these written submissions, the said Defendants have made a new disclosure, to the effect that Defendant No. 1 has stopped manufacturing and marketing the infringing product after service of the suit. The relevant portion of the written submissions reads as under: “Yet, being a Law abiding entity, after the service of present suit, Defendant No.1 has voluntarily withdrawn manufacturing order issued for the product ‘FERROTOK PLUS’ and stopped marketing/ selling the same, till they get full details of suit patent and examined their product through Government approved Lab as to weight ratio analysis. The Defendant further declares that they will not launch the product ‘FERROTOK PLUS’ in market again in any composition which will be infringing the patented rights of Plaintiffs. At present neither Defendant No.1, nor his stockists, whole sellers have any stock of ‘FERROTOK PLUS’ with them. The Defendant No.1sincerely regrets the mistake of its officials in inaccurate website description and as such they have withdrawn the website details for the time being and the same will now be uploaded after proper examination as to correctness of contents and the same shall be in full consonance of the law of the and. It is further submitted that the Defendant No.1 through its officials realized the demand of Iron related medicine, which can act as a food supplement towards the end of 2024 and then contacted Defendant No.2, who is active in the field of Drug Manufacturing since 2018. The drug composition and formulations were proposed by Defendant No.2 and based on effectiveness and pricing issues as recommended by Defendant No.2, Defendant No.1 started marketing the question product under the brand name of ‘EFRROTOK PLUS’ since February 2025.” (Emphasis Supplied)
CASE SETUP BY THE PLAINTIFF IN REJOINDER
9. In response, Mr. Dayan Krishnan, learned senior counsel appearing on behalf of the Plaintiffs, stated that the FER issued by the Patent Office on 13.01.2020 is the initial objection from the Indian Patent Office. 9.[1] He stated that the Plaintiffs filed a response to the FER on 12.07.2020[3]. Subsequently, the Controller issued a hearing notice on 18.10.2021. Since, the Controller was satisfied with the response filed by the Plaintiffs/patentee, the patent application was granted on 29.11.2021. He stated that thus the Plaintiffs have overcome the Novelty, inventive step, and the objections under Section 3(e) of the Act of 1970, raised by the Indian Patent Office. The Suit Patent has been valid and subsisting for the past four [4] years. 9.[2] He stated that the “as granted” claims have been filed along with the Affidavit e-filed on 08.08.2025[4] [as downloaded from the Patent Office website]. He clarified before the Court that, in accordance with the practice before the Indian Patent Office, any time an amendment in claims [i.e., 24.05.2021] is filed, it is done by mentioning the priority date of the patent. 9.[3] He stated that with regard to the date of patent, and the date of Claims filed, the E-register Status Page[5] and the Certificate of Grant[6] for IN’949, Filed as Document No. 15 in Plaintiff’s Document. vide diary number E-5635238/2025 Filed as Document No. 10 in Plaintiff’s Document.

ANALYSIS AND CONCLUSION
10. According to section 10(4)(c)8 of the Act, the claims of a complete specification define the scope of a patent, and claim construction forms the foundation of a patent infringement analysis [Re. Guala Closures SPA v. AGI Greenpac Limited[9] ]. Moreover, a comparison of the claims of the Suit Patent with the impugned product further aids the infringement analysis [Re. Mold Tek Packaging Ltd. v. Pronton Plast Pack (P) Ltd.10 ]. Therefore, the claim construction and claim mapping filed by the Plaintiffs is essential for adjudicating the present application.
11. At the hearing dated 08.08.2025, upon examining the claim mapping, this Court noted that the component of independent Claim 1 of the suit patent—‘Guanosine Nucleotide’—specifically claimed in Claim 2 as ‘Guanosine Monophosphate’ (GMP), is absent in the Defendants’ product. Instead, the Defendants’ product contains Disodium Guanosine 5- Monophosphate. Consequently, the Plaintiffs were directed to file an affidavit clarifying this aspect.
10. Contents of specifications. – xxx (4) Every complete specification shall— xxx
(c) end with a claim or claims defining the scope of the invention for which protection is claimed.
12. The Plaintiffs handed over the Affidavit dated 08.08.202511 in the Court on 11.08.2025. Upon perusal of the said Affidavit, this Court is persuaded by the submission of the Plaintiffs that the usage of the term ‘comprising’ in the independent Claim 1 gives the claim a broader protection to include minor variations of the claimed components. The Plaintiffs have relied upon the Judgment of the Division Bench of this Court in F. Hoffmann- La Roche Ltd. & Anr. v. Cipla Ltd.12 to contend that the use of the term comprising in a Patent Claim is enabling and not restrictive. In this aspect a reference may be made to the ‘Title 7: Patent Drafting Conventions and Specific Terms’ in Chapter 9 of Terrell on the Law of Patents, 19th Edition13. The relevant paragraph of the said chapter is reproduced here below: ““Comprising” A requirement that a claim “comprises” certain elements does not mean that other elements may not be present: “comprising” does not mean “only consisting of” [Emphasis supplied]
13. Moreover, it is also settled principle that, claims are to be read with the complete specification. In this aspect, a reference may be made to the decision of the Supreme Court in Biswanath Prasad Radhey Shyam v. Hindustan Metal Industries14. A perusal of the complete specification15 of the Suit Patent under the heading “Detailed description of the invention” at internal page no. 11 show a disclosure of the Disodium Guanosine Monophosphate. Filed vide diary number E-5635238/2025 page no. 273 para 9-129
Filed as Document No. 12 in the Plaintiff’s Document The relevant paragraph of the complete specification of the suit patent is reproduced here below for clarity: - “In preferred aspect, the pharmaceutical composition/formulation of the present invention comprises a synergistic combination of Lactoferrin, Disodium GMP and pharmaceutically acceptable excipients.”
14. As per the Affidavit dated 08.08.2025, this disclosure has also been enabled under the heading “Examples” of the complete specification of the suit patent. The relevant example is reproduced here below: - “Example 22 Sr. No Ingredients Wt. in mg % W/W Dry Mixing 1 Lactoferrin 50 12.50
14 InstaMoistshield 8.0 2.0 15 Isopropyl alcohol QS QS 16 Methylene dichloride QS QS Enteric coating agent 17 Methacrylate Copolymer 17 8.00 18 Sodium alginate 9
15. Upon perusal of Independent Claim 1, dependent claim 2 along with complete specification of the Suit Patent, it can be discerned that the ‘Disodium Guanosine 5-Monophosphate [DGMP], which is a disodium salt of Guanosine monophosphate [GMP] is covered in the Suit Patent.
16. Therefore, by mapping the claims of the Suit Patent against each element of the Defendants’ product, the Plaintiffs have established a strong prima facie case demonstrating infringement of the Suit Patent. In its written submissions, an undertaking is also given by Defendant Nos.1, 3 and 4 that the said Defendants would neither manufacture nor place any order or launch any infringing product during the Suit Patent’s term of protection.
17. Upon an enquiry raised by this Court at the hearing dated 14.08.2025, the Defendants have not explained how they came to adopt the said formula (formulation) for their product. Instead, the Defendants have made bald allegations that many parties were using a similar formula and in particular that the formula is available with Defendant No. 2. Despite granting opportunity to the Defendants to state its defence, neither at the hearing dated 14.08.2025 nor with its written submissions dated 24.08.2025, Defendants have not filed any documents to rebut the certificate of analysis 16 of Defendants’ product filed by the Plaintiff. In fact, Defendant No. 2’s wilful absence despite advance service substantiates the contentions of the Plaintiffs that Defendant No. 2 is knowingly manufacturing the product which infringes the Suit Patent.
18. The Defendants’ infringing acts are causing the Plaintiff substantial Filed as Document No. 20 in Plaintiff’s Document loss, both financial and otherwise. Accordingly, the balance of convenience lies in favour of the Plaintiff. Furthermore, if the Defendants are not restrained, the sale of the allegedly infringing products is likely to cause further harm and damage to the Plaintiff. In light of the above, the Court finds it appropriate to grant an interim injunction in favour of the Plaintiffs.
19. The Plaintiffs have applied for the certified copies of the granted patent specification and claims on 22.07.2025 and undertake to file the same as and when available. The Plaintiffs are directed to serve the same to the Defendants.
20. Accordingly, Defendant Nos. 1, 2, 3 and 4, their partners, related parties, servants, employees, officers, agents, stockists, distributors, dealers and all others acting for and on their behalf are restrained from making, using, selling, distributing, advertising, offering for sale, selling, exporting, importing, and in any other manner, directly or indirectly, commercializing or dealing in any product or using any process that infringes the subject matter of Indian Patent No. 382949, or any of the claims thereof. This injunction qua Defendant Nos. 1, 3 and 4 is confirmed until final disposal of the suit. Vis-à-vis Defendant No. 2, this injunction shall operate until the next date of hearing.
21. Regarding the Plaintiffs’ Suit Copyright, the undertaking of the Defendant that allegedly copied description and details present on the Defendant No.1’s website is withdrawn, and the same will be updated with true information without causing further confusion to the general public, including patients, is taken by this Court on record. Therefore, the interim injunction is also allowed regarding the Plaintiff’s Suit Copyright until the final disposal of the suit.
