The company claims that Customs reversed its previous ruling without notifying Masimo, which learned of the decision only after Apple's announcement to reintroduce the feature. Masimo accuses Apple of patent infringement and trade secret theft, having previously secured a block on certain Apple smartwatch imports. The lawsuit seeks to halt Customs' approval and prevent Apple from selling the watches with the blood-oxygen feature. By Blake Brittain WASHINGTON, Aug 20 (Reuters) - Medical monitoring technology company Masimo (MASI.O) sued U.S. Customs and Border Protection on Wednesday over a decision by the agency that allowed Apple (AAPL.O) to import Apple Watches with blood-oxygen reading technology during a patent dispute between the companies. Masimo said in the lawsuit in Washington, D.C., federal court that Customs improperly determined that Apple can import watches with pulse oximetry technology, reversing its own decision from last year without notifying Masimo. Masimo told the court that it learned of the agency’s August 1 decision only after Apple announced it would reintroduce blood-oxygen reading to its watches last week. Spokespeople for Apple and Customs did not immediately respond to requests for comment. A Masimo spokesperson declined to comment. Irvine, California-based Masimo has accused Apple of hiring away its employees and stealing its pulse oximetry technology to use in its Apple Watches. Masimo has separately sued Apple for patent infringement and trade secret theft in ongoing federal court cases. Masimo convinced the U.S. International Trade Commission to block imports of Apple’s Series 9 and Ultra 2 smartwatches in 2023 based on a determination that Apple’s technology for reading blood oxygen levels infringed Masimo’s patents. Apple has continued to sell Customs-approved redesigned watches without pulse oximetry since the ITC’s decision. Apple said on Aug. 14 that it would reintroduce its smartwatches’ blood-oxygen reading capabilities with approval from Customs. Masimo said the agency’s decision to approve the watches without input from Masimo or any “meaningful justification” deprived the company of its rights. “CBP’s function is to enforce ITC exclusion orders, not to create loopholes that render them ineffective,” Masimo said. Masimo asked the Washington court to halt the agency’s ruling and continue to block Apple from selling watches with the blood-oxygen feature. ### Related Stocks - [MASI.US - Masimo](https://longbridge.com/en/quote/MASI.US.md) - [AAPL.US - Apple](https://longbridge.com/en/quote/AAPL.US.md) - [AAPB.US - GraniteShares 2x Long AAPL Daily ETF](https://longbridge.com/en/quote/AAPB.US.md) - [AAPD.US - Direxion Daily AAPL Bear 1x Shares](https://longbridge.com/en/quote/AAPD.US.md) - [AAPU.US - Direxion Daily AAPL Bull 2X Shares](https://longbridge.com/en/quote/AAPU.US.md) - [AAPX.US - T-Rex 2X Long Apple Daily Target ETF](https://longbridge.com/en/quote/AAPX.US.md) - [AAPY.US - Kurv Yield Premium Strategy Apple Aapl ETF](https://longbridge.com/en/quote/AAPY.US.md) - [APLY.US - YieldMax AAPL Option Income Strategy ETF](https://longbridge.com/en/quote/APLY.US.md) ## Related News & Research | Title | Description | URL | |-------|-------------|-----| | 苹果加速研发 AI 眼镜、挂饰及摄像头版 AirPods | 作为向人工智能驱动硬件转型的一部分，苹果公司正加速开发三款新型可穿戴设备，包括智能眼镜、一款挂饰设备以及具备扩展 AI 功能的 AirPods。这些设备将围绕 Siri 数字助理构建，并依靠具备不同功能的摄像头系统，根据视觉语境执行操作。苹 | [Link](https://longbridge.com/en/news/276167877.md) | | 段永平试水 “AI 交易”：卖苹果加仓英伟达，“新入” CoreWeave、Credo 和 Tempus | CoreWeave 专门搭建高性能 GPU 集群，把算力租给 AI 公司和企业客户；如果说 GPU 是心脏，Credo 提供的高速互联芯片和光模块就是血管，跟 AI 服务器迭代高度绑定；Tempus 则致力于将 AI 应用于精准医疗，尤其是 | [Link](https://longbridge.com/en/news/276189117.md) | | 期权热点｜周二 AAPL 涨 3%，部分看涨期权飙升 2900% | 美东时间 02 月 17 日，苹果期权总成交 1120645 张，看涨期权占比 69%，看跌期权占比 30%。 | [Link](https://longbridge.com/en/news/276195850.md) | | Bey Douglas LLC 减少了其在苹果公司 $AAPL 的股票持仓 | Bey Douglas LLC 在第三季度减少了对苹果公司（NASDAQ:AAPL）21.0% 的持股，目前持有 21,365 股，价值约为 544 万美元。这一减持使苹果成为其投资组合中第七大持仓，占其持有资产的 4.0%。其他机构投资者 | [Link](https://longbridge.com/en/news/276207627.md) | | Twin Peaks Wealth Advisors LLC 购入了苹果公司 4,015 股股票 $AAPL | Twin Peaks Wealth Advisors LLC 在第三季度将其在苹果公司（NASDAQ:AAPL）的持股增加了 6.4%，额外购买了 4,015 股，使其总持股达到 66,353 股，价值约为 1,690 万美元。苹果公司占该 | [Link](https://longbridge.com/en/news/276207616.md) | --- > **Disclaimer**: This article is for reference only and does not constitute any investment advice.
