Chroma ATE Inc. has filed a lawsuit under the Fair Trade Act against Good Will Instrument Co., Ltd. (GW Instek) for manufacturing and selling an automatic test system product (also named “ATS-8000”) that, without authorization, uses the product name and user interface of Chroma’s switching power supply automatic test system "8000" (widely known in the market as ATS 8000).

Chroma has long been committed to delivering technologies needed by industry today while developing innovative solutions for tomorrow. The Chroma ATS 8000 offers a high degree of compatibility, enabling users to perform tests using multiple instruments concurrently without concerns about driver or interface-related incompatibilities, resulting in significantly increased testing efficiency. With a single ATS 8000 system, users can connect multiple test & measurement instruments to run tests in parallel, delivering lower cost and higher throughput for our customers.

Since its launch, the ATS 8000 automatic test system—thanks to its open architecture, powerful and scalable software and hardware, and exceptional accuracy, stability, and reliability—has been adopted by leading manufacturers worldwide and has earned widespread acclaim. It is widely recognized as the benchmark and de facto industry standard for switching power supply testing. Many engineers even highlight proficiency with the ATS 8000 on their resumes as a plus.

Chroma strives to help customers bring new technologies to market and drive industry progress—a mission that depends on vigorously safeguarding our R&D assets. Chroma values and respects intellectual property rights, both our own and those of others. Because technological innovation is central to the long-term value we create for customers, we will continue to resolutely defend our innovations and rights.
