Biocytogen Responds to Harbour BioMed's Patent Claims: RenNano® is an Independently Developed Platform with Distinct Innovation and Full Legal Standing
Article content
BEIJING — In response to Harbour BioMed's recent press release regarding a procedural development in their ongoing legal claim, Biocytogen issues the following statement:
Article content
Biocytogen stands by its core values of independent innovation, respect for intellectual property, and a commitment to fair competition. The RenNano® platform is the result of independent, original R&D, based on Biocytogen's proprietary genome editing technologies. Its technical principles, design strategy, and IP scope are fundamentally different from the patents in dispute.

Biocytogen Will Resolutely Take Legal Actions to Protect Its Rights
Article content
The RenNano® platform employs a large-fragment knock-in strategy that incorporates over 120 human V genes in situ, enabling a complete and functional human heavy chain antibody repertoire. In stark contrast, Harbour BioMed's HCAb platform introduces only 9 V genes through a small-fragment transgenic approach. This key difference reflects not only divergent technical strategies but also the depth, innovation, and translational potential of Biocytogen's antibody discovery platforms.

The decision referenced in Harbour BioMed's PR involves a procedural ruling on jurisdiction only and does not address the substance of the patent infringement case. Furthermore, the CNIPA's affirmation of patent validity is a routine administrative process that does not imply infringement. The underlying lawsuit has not yet entered the trial phase.
Article content
Biocytogen is currently evaluating all legal options and will resolutely defend its IP rights and scientific reputation. The RenNano® platform has been fully validated and is supported by a robust portfolio of domestic and international patents, clearly documenting its originality and independence.

We remain confident in:
Article content
The technical integrity and legal foundation of the RenNano® platform;
The non-infringement of any third-party IP;
Our continued leadership in antibody discovery and therapeutic innovation.
Article content
According to public records, the Chinese patent related to Harbour BioMed's HCAb platform is set to expire on July 22, 2025, further underscoring the short-sighted nature of any speculative claims. Regardless, Biocytogen will continue to uphold its rights, ensure business continuity, and deliver transformative technologies for global partners and patients.
