AMEC PREVAILS IN SECOND INSTANCE OF TRADE SECRET LAWSUIT FILED AGAINST LAM RESEARCH CORPORATION

SHANGHAI,July 11,2023 -- Advanced Micro-Fabrication Equipment Inc. China (AMEC) announced today that it has prevailed in the second instance of a trade secret misappropriation lawsuit it filed in China against Lam Research Corp. of Fremont,California (Lam).

In its decision of June 30,2023,the Court ordered Lam to destroy a technical document and two photographs relating to AMEC's plasma ether that it had illegally obtained. The Court also enjoined Lam and two of Lam's individual defendants from disclosing,using or permitting others to use AMEC's proprietary technical trade secrets. The Court also ordered Lam to pay damages and legal costs to AMEC for its misappropriation of AMEC's trade secrets.

AMEC filed the first instance suit in the Shanghai No. 1 Intermediate People's Court in December 2010. AMEC won the first instance in March 2017 after years of hard work. The case was then appealed to the Shanghai High Court. The second-instance judgement follows a six-year battle to protect and safeguard AMEC's valuable intellectual property.

"This Court victory reinforces the critical importance AMEC places on protecting our intellectual property and innovation," said Dr. Gerald Z. Yin,Chairman and CEO of AMEC. "Innovation is at the heart of AMEC. AMEC has invested heavily in research and development to bring pioneering and beneficial technology to our customers around the world. At the same time,we spare no effort in protecting our proprietary technology and intellectual property. We will not tolerate misappropriation or other dishonorable behavior that puts our business at risk."
