Exhibit 99.1
Regentis Receives Japanese Patent allowance,
Strengthening its Global GelrinC Intellectual Property
Portfolio with New Proprietary Manufacturing Technology
Patent expands intellectual property protection in one of the world’s largest cartilage repair markets
GelrinC is a cell-free hydrogel delivered in a single ~10-minute procedure eliminating the need for cell harvesting, lab processing, and surgeries—potentially setting a new standard of care for knee cartilage repair
HERZLIYA, Israel, July 20, 2026 - Regentis Biomaterials Ltd. (“Regentis” or the “Company”) (NYSE American:RGNT), a regenerative medicine company focused on innovative tissue repair solutions, announced today that the Japan Patent Office has issued a Notice of Allowance for the Company’s patent application titled “Organic Solvent Free Compositions Comprising Protein-Polymer Conjugates and Uses Thereof” for its proprietary organic solvent-free manufacturing process and ready-to-use liquid formulation used in GelrinC®, the Company’s regenerative treatment for articular cartilage injuries.
The allowance further strengthens Regentis’ expanding global intellectual property portfolio supporting GelrinC in the treatment of painful and debilitating injuries to focal articular knee cartilage. This comes as the Company advances commercialization activities in Europe, has surpassed 50% enrollment in its pivotal U.S. trial, and is evaluating opportunities to expand into additional international markets.
“Our proprietary manufacturing technology is a key competitive advantage for GelrinC, and this Notice of Allowance significantly strengthens our intellectual property position in one of the world’s most important orthopedic markets,” said Ehud Geller, CEO and Executive Chairman of Regentis. “As we prepare for the commercial launch of GelrinC in Europe, expanding patent protection in major international markets reinforces the long-term value of our technology platform and supports future commercialization opportunities.”
The allowed patent covers proprietary protein-polymer conjugate compositions and manufacturing methods designed to eliminate the use of organic solvents while enabling stable, ready-to-use liquid formulations. The technology offers important manufacturing advantages, including improved process efficiency – 5x increase in yield, enhanced environmental profile, simplified production, and additional scalability for commercial manufacturing.
The patent complements Regentis’ growing worldwide intellectual property portfolio protecting GelrinC across product composition, manufacturing methods and therapeutic applications.
Japan represents one of the world’s largest and fastest-growing markets for cartilage repair technologies. Independent market research estimates the Japanese cartilage repair market will grow to nearly $289 million by 2030, driven by an aging population and increasing demand for joint-preserving therapies.
Published research estimates that approximately 25 million people in Japan over the age of 40 have radiographic knee osteoarthritis, including roughly 8 million patients with symptomatic disease, underscoring the growing need for innovative cartilage repair treatments.
About GelrinC®
Regentis’ lead product, GelrinC®, is a cell-free, off-the-shelf hydrogel implant having synchronized erosion and resorption for the treatment of painful and debilitating injuries to focal articular knee cartilage. As an innovative regenerative medical product, GelrinC® offers an unprecedented solution that gives surgeons and payers an off-the-shelf, ready to use, simple to perform, reliable, and cost-effective procedure that provides patients with a single, 10-minute procedure, faster recovery, sustained pain relief, and functional improvement for more than 5 years, based on clinical study results to date. No effective off-the-shelf, ready to use treatment for focal knee cartilage defects is currently available on the market. GelrinC® has CE Mark approval in the European Union and is now being evaluated in a pivotal U.S. Food and Drug Administration (FDA) study, which has completed over 50% enrollment.
About Regentis Biomaterials
Regentis Biomaterials Ltd is a regenerative medicine company dedicated to developing innovative tissue repair solutions that restore health and enhance quality of life. With an initial focus on orthopedic treatments, Regentis’ Gelrin platform technology, based on synchronized, degradable hydrogel implants, regenerates damaged or diseased tissue including inflamed cartilage and bone. Regentis’ lead product GelrinC®, is a cell-free, off-the-shelf hydrogel that is eroded and resorbed in the knee, allowing the surrounding cells to regenerate the cartilage in a controlled and synchronous process. GelrinC® aims to address a market of approximately 470,000 cases for cartilage knee repair annually in the U.S. where no off-the-shelf treatment is available.
