BILLERICA, Mass.--(BUSINESS WIRE)-- Entegris, Inc. (Nasdaq: ENTG), a leading supplier of critical advanced materials and process solutions for the semiconductor and other high-technology industries, today announced recent decisions in Taiwan and China upholding patents covering key Entegris colloidal silica slurry technology used in chemical mechanical planarization (CMP) applications. The decisions further reinforce the strength of Entegris’s global intellectual property portfolio and underscore the Company’s technology leadership in advanced CMP slurries for semiconductor manufacturing. On July 14, 2026, the Taiwan Intellectual Property and Commercial Court rejected a challenge by an affiliate of Qnity Electronics, Inc. (“Qnity”) and upheld the validity of Taiwan Patent No. I561622. On August 10, 2026, China’s National Intellectual Property Administration likewise rejected a challenge by a Qnity affiliate and upheld the validity of Chinese Patent No. 107075343B. Both patents relate to acidic colloidal silica slurry technology. These decisions follow Entegris’s prior enforcement success involving the same patent family. In 2021, the U.S. International Trade Commission (ITC) found that Qnity’s Optiplane CMP slurry products infringed U.S. Patent No. 9,499,721 and issued exclusion and cease and desist orders prohibiting the importation, marketing, and sale in the United States of Qnity’s infringing products. In 2024, Entegris resolved related U.S. district court litigation concerning the same Optiplane products. The resolution maintained the exclusion order and cease and desist orders granted by the ITC, which remain in force until 2035. “Entegris’s technology leadership is built on decades of innovation that enables the semiconductor industry’s most critical manufacturing processes” said Olivier Blachier, President, Materials Solutions and Senior Vice President, Chief Innovation Officer of Entegris. “These decisions reinforce the strength of our intellectual property and our commitment to protecting the innovations that differentiate Entegris, strengthen our competitive position, and support long-term value creation for customers and shareholders.” ABOUT ENTEGRIS Entegris is a leading supplier of critical advanced materials and process solutions for the semiconductor and other high-tech industries. Entegris has approximately 7,700 employees throughout its global operations and is ISO 9001 certified.
