LUND, SWEDEN / ACCESS Newswire / March 10, 2026 / Alligator Bioscience (STO:ATORX), a clinical-stage biotechnology company developing tumor-directed immuno-oncology antibody drugs, today announced that the United States Patent and Trademark Office (USPTO) has granted a patent covering Alligator's proprietary bispecific antibody format. The granted patent provides protection for the structural design of tetravalent bispecific antibodies capable of dual antigen binding.
The patent covers a versatile antibody architecture designed to enable stable and efficient assembly of bispecific antibodies, including configurations targeting immune modulators and tumor-associated antigens. This platform is intended to support the development of next-generation immunotherapies across a range of oncology indications and combination strategies.
The bispecific antibody format covered by the patent underpins multiple programs within Alligator's research platform and has already demonstrated external validation. In September 2025, Alligator entered into an evaluation and option agreement covering the RUBY antibody format, highlighting the commercial and strategic interest in Alligator's antibody engineering capabilities.
"This patent grant strengthens the intellectual property foundation around our bispecific antibody platform and highlights the value of our technology beyond mitazalimab," said Søren Bregenholt, CEO of Alligator Bioscience. "It supports our strategy to build long-term value through our innovative antibody formats, both within our own pipeline and through partnerships, as exemplified by the RUBY agreement."
