CollPlant Biotechnologies received a Korean patent allowance on February 26 2026 for its photocurable dermal filler technology, a key component of the company’s planned injectable soft‑tissue filler line. The allowance protects the composition and its use for tissue augmentation through 2039, giving the company a 15‑year protection period in South Korea, a major aesthetic‑medicine market.
The approval expands CollPlant’s intellectual‑property footprint into South Korea and is part of a broader global strategy that has secured similar patents in the United States, Europe, China, Brazil, Australia, Israel, Japan, and now South Korea. The company’s partnership with AbbVie’s Allergan for development and commercialization of dermal and soft‑tissue fillers further underscores the strategic importance of this milestone.
The technology is a polymerizable solution that is injected into sub‑epidermal tissue and polymerized in situ with external light. The resulting scaffold is designed to support structural tissue restoration and promote long‑term contour stability, offering a regenerative matrix that may enhance tissue integration and durable structural improvement. "Beyond skin lifting, our photocurable rhCollagen‑based filler platform was designed to support structural tissue restoration. Upon light activation, the material forms a supportive scaffold intended to enhance long‑term contour stability. The technology is designed not only to restore facial contours but also to provide a regenerative matrix that may promote tissue integration and durable structural improvement," said CEO Yehiel Tal.
CollPlant has faced declining revenue growth and negative profit margins in recent periods, and it has implemented cost‑cutting measures and workforce reductions to extend its cash runway. The new patent approval could support future commercialization and licensing opportunities, providing a potential source of value as the company moves the product toward clinical trials. "This patent allowance represents another important milestone in executing our strategy to expand the clinical and commercial applications of our rhCollagen platform into high‑value aesthetic markets," Tal added. "South Korea is a strategically important market in aesthetic medicine, and strengthening our intellectual property position in this region further enhances the long‑term value of our technology."
Market reaction to the announcement has been muted, with the company’s stock trading near its 52‑week low and a market capitalization of $8.5 million. Analysts note that the company appears undervalued at current levels and anticipate sales growth, predicting a return to profitability this year. "With patent protection extending through 2039, we believe this innovation positions us to compete effectively, upon completion of development, in a global injectable soft‑tissue filler market currently estimated to exceed $6 billion and continuing to grow," Tal said.
The Korean patent allowance strengthens CollPlant’s competitive position in a high‑growth market and provides a foundation for future commercialization. While the product remains in development, the approval signals progress in the company’s long‑term strategy to bring a regenerative dermal filler to market and to generate new revenue streams in the aesthetic‑medicine sector.
