• Patent EP 3 332 028 B1 granted by the European Patent Office covers the identification and use of genomic variants for the diagnosis of antibiotic resistant bacteria.
• The opposition division of European Patent Office ruled to maintain the patent as granted with minor modifications.

ROCKVILLE, Md., June 26, 2023 (GLOBE NEWSWIRE) -- OpGen, Inc. (Nasdaq: OPGN, “OpGen”), a precision medicine company harnessing the power of molecular diagnostics and informatics to help combat infectious disease, and OpGen subsidiary, Ares Genetics, which strives to become a leader in bacterial genomics and AI-powered prediction of antimicrobial resistance (AMR), announced today that one of its key patents under opposition has been successfully maintained.

The patent with the title GENETIC RESISTANCE PREDICTION AGAINST ANTIMICROBIAL DRUGS IN MICROORGANISM USING STRUCTURAL CHANGES IN THE GENOME was granted in Europe on January 6, 2021 and in China on January 10, 2023.

In September 2021, an opposition was filed by a Swedish opponent against the patent grant by the European Patent Office. In a hearing on Thursday, June 22, 2023, the opposition division of the European Patent Office ruled in favor of maintaining the patent as granted with a minor amendment to one of the claims.

The patent as maintained broadly covers the prediction of AMR in pathogens based on any genetic determinants involving two or more nucleotides.

The patent is an important component of the comprehensive intellectual property portfolio protecting Ares Genetics' unique database ARESdb and machine learning based approaches for predicting phenotypic antibiotic susceptibility and resistance directly from genomic data, an approach also referred to as “genomic AST.” Under the patent, both the computational identification of genetic determinants of AMR and genomic AST can be carried out, in order to diagnose AMR infections in patient samples.

“The patent covers the use of alignment-free methods, which are not only more computing resource efficient, but are also generally required to discover and resolve more complex structural variants, which is particularly important in this context,” says Dr. Arne Materna, CEO and Managing Director of Ares Genetics. “We therefore welcome the favorable ruling by the European Patent Office, an outcome that we believe underscores the validity, novelty and potential value of similar pending patent applications in our portfolio.”

OpGen believes that bacterial whole genome sequencing (WGS) is becoming the method of choice for detecting and controlling healthcare associated outbreaks. Genomic AST as covered in the patent has the potential to expand the utility of WGS beyond outbreak-surveillance into the realm of diagnostic applications to inform therapy.
