## Exhibit 99.1

**Exhibit 99.1**

**Regentis Biomaterials Granted New U.S. Patent for its Off-the-Shelf Regenerative Cartilage Repair Product GelrinC** 

*Patent protects ready to use liquid formulation of GerlinC which improves efficiency and focus for surgeons, resulting in a 10-minute procedure*

*Robust IP portfolio includes 35 issued patents to date worldwide*

*GerlinC is in a pivotal FDA trial, has received regulatory approval in the EU, and is the world's first off-the-shelf regenerative treatment for knee cartilage repair*

Herzliya, Israel, December 18, 2025— Regentis Biomaterials Ltd., ("Regentis" or the "Company") (NYSE American: RGNT), a regenerative medicine company focused on innovative tissue repair solutions, today announced that the U.S. Patent and Trademark Office has issued the Company a patent titled "Organic Solvent Free Compositions Compromising Protein-Polymer Conjugates and Uses Thereof" for its lead product, GerlinC®, addressing the liquid, ready to use version of the product, as well as improved processes for its production that avoid the use of organic solvents.

This patent's primary claims are focused around GelrinC's liquid ready-to-use formulation, reflecting Regentis' focus on simplifying procedures for surgeons while improving patient experience. GelrinC is delivered in liquid form to conform precisely to the geometry of the cartilage wound and is then cured using UV light to form an elastomeric, temporary, programmed implant. The straightforward, approximately 10-minute procedure eliminates complex preparation steps and distractions for surgeons and enables a brief, convenient office visit for patients.

"This most recent patent, our ninth in the U.S., comes at an important time as we recently surpassed 50% enrollment in our pivotal U.S. Food and Drug Administration ("FDA") trial for GelrinC in the treatment of knee cartilage repair," stated Regentis' Executive Chairman, Dr. Ehud Geller. "The patent provides broad protection for GelrinC through 2038, with the potential for additional extensions tied to future innovations. Our IP strategy pairs continuous patenting of new innovations with broadly drafted claims that strengthen and extend protection around our platform's core technology."

**About GelrinC**

Regentis' lead product, GelrinC®, is a cell-free, off-the-shelf hydrogel synchronized erosion and resorbable implant for the treatment of painful 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 4 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.
