Kioxia Ordered to Pay $229 Million in US Patent Lawsuit, Pledges to Pursue All Legal Remedies
半導體大廠鎧俠控股於8月3日宣布，其子公司在美國的專利侵權訴訟中被判支付約2.29億美元（約366億日圓）賠償金。此案由美國衛星通信公司Viasat於2021年提起，指控鎧俠侵害其1項專利請求項。鎧俠表示無法接受判決，將採取包括上訴在內的一切法律手段，並已於2027年3月期第一季財報中計提同額訴訟損失準備金，強調此判決不影響產品供應。
WISECODE Take
On August 3, 2026, Kioxia announced that the US District Court for the Western District of Texas ordered it to pay Viasat approximately $229 million, breaking the myth that only non-practicing entities file high-damage lawsuits. Originating from a lawsuit filed on November 29, 2021, the court found Kioxia infringed on just 'one' patent claim. Like losing a sports match over a single penalty, this reminds us that even with tight defense, a single vulnerability can decide the outcome. For companies not entering the US or not involved in high-frequency communication, this case has no impact. However, global manufacturers risk hitting patent landmines without proper checks; Zhidian's Patent Portfolio Health Check is designed to address this. Actionable steps: First, review patent maps for export products against US competitors; second, establish litigation reserve mechanisms, as Kioxia did, to mitigate financial impact. Patent defense is not about total numbers, but whether key nodes are secured.
