Masimo filed suit against US Customs and Border Protection in the US District Court for the District of Columbia, alleging the CBP unjustifiably reversed a January 2024 order that forced Apple to disable Blood Oxygen measurement in the US. Apple disabled the SpO2 feature on Watch Series 9 and Watch Ultra 2 in January 2024 to avoid a possible import ban while retaining the pulse oximeter hardware. Apple reintroduced the pulse oximeter via an OTA update on August 14 for Watch Series 9, Series 10, and Ultra 2, and allegedly provided the feature without infringing Masimo patents.
According to the court document shared by Bloomberg Law, Masimo has filed a lawsuit against the US CBP for reversing its January 2024 order that forced Apple to disable the Blood Oxygen measurement feature in the US. The company has filed a lawsuit in the US District Court of the District of Columbia, alleging that the US CBP, in its August 1 ruling, did not justify the reversal of its stand on the issue.
To avoid a possible import ban in the US, Apple stopped offering its blood oxygen feature on the Watch Series 9 and Watch Ultra 2 in January 2024. While the hardware was still present on the smartwatches, the tech giant had merely disabled the pulse oximeter feature in the country. In its earlier lawsuit, Masimo had claimed that the Cupertino tech giant's SpO2 measurement feature infringed on the patents the medical tech company held.
On August 14, Apple reintroduced the pulse oximeter feature via an OTA update for the Apple Watch Series 9, Watch Series 10, and Watch Ultra 2 in the US. Since it had not removed the SpO2 sensor, it was easier for the company to bring the feature back. Also, Apple allegedly found a way to provide the same without infringing on Masimo's patent.
