Frimline Private Limited and its parent company (hereinafter as \u201cFrimline\u201d) filed a suit alleging infringement of Indian Patent No. 382949, titled \u201cA Pharmaceutical Composition for Anaemia\u201d, and copyright infringement of its website. The patent discloses a synergistic composition of Lactoferrin and Guanosine Nucleotide (or its salts) for treating iron deficiency and inflammatory anaemia. Frimline had commercialised the invention since 2018 under the brands FERRONEMIA and FERRONOMIC. In July 2025, Frimline discovered that the defendants (hereinafter as \u201cK-smatco\u201d) were manufacturing and selling FERROTOK PLUS, which allegedly contained the same composition, and had also copied substantial content from Frimline\u2019s website.<\/p>\n
-Whether K-smatco\u2019s product FERROTOK PLUS infringed Frimline\u2019s patent.<\/p>\n
-Whether the patent claims, particularly the term \u201ccomprising\u201d, covered salts such as Disodium Guanosine 5-Monophosphate (Claim 1 referred to \u201cguanosine nucleotide,\u201d and Claim 2 narrowed it to Guanosine Monophosphate (GMP) and DGMP was not expressly claimed, but was disclosed in the detailed description and example of the specification).<\/p>\n
-Whether Frimline established a prima facie case warranting grant of an interim injunction.<\/p>\n
-Whether copying content from Frimline\u2019s website constituted copyright infringement.<\/p>\n
Frimline contended that K-SMATCO\u2019s FERROTOK PLUS was identical to its patented formulation and clearly within the scope of IN 382949. The specification expressly disclosed Disodium Guanosine 5-Monophosphate (DGMP), a salt of GMP, covered under Claim 1, which uses the inclusive term \u201ccomprising.\u201d All objections on novelty, inventive step, and Section 3(e) were overcome before the patent was granted in 2021. Relying on F. Hoffmann-La Roche v. Cipla and Terrell on the Law of Patents, Frimline argued that \u201ccomprising\u201d extends protection to salts and minor variations. Frimline supported its arguments by producing Claim mapping and lab analysis to confirm ingredient-wise similarity. Frimline also alleged copyright infringement of its website content under Section 13(1)(a) of the Copyright Act.<\/p>\n
K-smatco contended that the patent lacked novelty and inventive step, as similar compositions were already available in the market. K-smatco alleged that Frimline had not produced certified copies of the amended claims and that the composition tested by Frimline might fall outside the claimed range. K-smatco further submitted that they had withdrawn the product and taken down the infringing website, expressing regret and claiming they would not relaunch until further verification.<\/p>\n
Placing reliance on Guala Closures SPA v. AGI Greenpac Ltd. (2024 SCC OnLine Del 3510)<\/em> and Mold Tek Packaging Ltd. v. Pronton Plast Pack (P) Ltd (2025 SCC OnLine Del 4883 (DB))<\/em>, the Court stated that, under Section 10(4)(c) of the Patents Act, claims determined the scope of protection, and infringement must be assessed through proper claim construction and mapping. The Court accepted Frimline\u2019s arguments that the term \u201ccomprising\u201d was non-restrictive and extended protection to minor variants such as salts. Referring to the detailed description and examples in the complete specification, the Court observed that Disodium Guanosine 5-Monophosphate was expressly disclosed and therefore covered under the claims. The Court further observed that K-smatco failed to produce any documentary evidence to rebut Frimline\u2019s analysis or to justify adoption of the same formulation. The Court opined that Frimline had a strong prima facie case and that the balance of convenience was in its favour, and affirmed that the sale of the infringing formulation could cause irreparable commercial and public harm.<\/p>\n The Court granted an interim injunction restraining K-smatco, their partners, and distributors from manufacturing, selling, or marketing any product infringing IN 382949 during the patent term. K-smatco\u2019s undertaking to withdraw the infringing website content was recorded, and interim protection was also granted for Frimline\u2019s copyright.<\/p>\n The Court reaffirmed the importance of using the term \u201ccomprising\u201d in patent claims, holding that it was inclusive and enabling rather than restrictive.<\/p>\n Citation:<\/strong> <\/span>CS(COMM) 808\/2025<\/p>\n Link:<\/strong><\/span> https:\/\/indiankanoon.org\/doc\/85349301\/<\/p>\n Article review and accessibility review: Mr. Gaurav Mishra<\/p>\n","protected":false},"excerpt":{"rendered":" In Frimline v.
