Masimo sues US Customs over Apple Watch imports

STORY: Medical monitoring technology company Masimo sued U.S. Customs and Border Protection on Wednesday.

It's over a decision by the agency that's allowed Apple to import Apple Watches with blood-oxygen reading tech during a patent dispute between the companies.

Masimo said in the lawsuit that Customs improperly determined that Apple can import watches with pulse oximetry technology, reversing its own decision from last year without any notification.

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.

The California-based medical tech firm has accused Apple of hiring away its employees.

As well as stealing its pulse oximetry technology to use in its watches.

Masimo has separately sued Apple for patent infringement and trade secret theft in ongoing federal court cases. Related Videos

It convinced the U.S. International Trade Commission to block imports of Apple's Series 9 and Ultra 2 smartwatches in 2023.

That was based on a determination that Apple's technology for reading blood oxygen levels infringed Masimo's patents.
