Portland, Oregon — December 5, 2025 — The IntelliCAD Technology Consortium (ITC), an international CAD software technology alliance, announced it filed suit today against China-based ZWSOFT Co., LTD. (Guangzhou) (“ZW”) and South Korea-based ZYX Technology Co., formerly known as Nitrosoft Co., Ltd. (“ZYX Tech”) alleging unauthorized use and distribution of ITC’s IntelliCAD® software technology. ITC’s claims include copyright infringement, trade secret misappropriation, unjust enrichment, and breach of contract. In the suit, ITC alleges ZYX Tech was and is selling, distributing, and/or donating “ZyxCAD,” a rebranded version of ZW’s “ZwCAD,” on a large scale and without proper authorization. Additionally, ITC asserts ZW has granted licensing rights for or software access to ITC’s proprietary software to ZYX Tech in a manner that violates ZW’s contractual obligations to ITC.
