A U.S. International Trade Commission judge issued a preliminary ruling stating that Apple's redesigned smartwatches do not infringe on patents held by medical technology company Masimo. This decision provisionally rejects Masimo's effort to reinstate an import ban on the popular devices over a dispute concerning blood-oxygen reading technology.
The ruling specifically addresses the updated Apple Watch models that were altered following a previous ban. The full ITC commission will now review this initial finding to make a final determination.
This case is a key development in a long-standing legal battle between Apple and Masimo. In December 2023, the ITC implemented an import ban on Apple's Series 9 and Ultra 2 watches after finding they violated Masimo's pulse-oximetry patents.
In response, Apple modified the watches to circumvent the ban, a redesign approved by U.S. Customs and Border Protection. Masimo contested this move, leading to the current proceedings. A separate U.S. Court of Appeals ruling recently upheld the original 2023 infringement decision, though Apple continues to import its redesigned watches.
This preliminary ruling is a significant victory for Apple, allowing it to continue selling its flagship wearable products in the U.S. market without immediate disruption. Apple stated it was pleased with the decision while it continues to evaluate other legal avenues.
For Masimo, the ruling represents a setback in its multi-front patent fight against the tech giant. The ongoing litigation, which includes claims of trade-secret theft and employee poaching, highlights the high stakes involved in the competitive medical technology and consumer electronics sectors.
While Apple has secured a favorable initial outcome, the dispute is far from over. The final decision rests with the full ITC commission. Investors and industry observers will be closely watching the commission's review, as a reversal could re-impose a costly import ban. The broader legal conflict will continue across multiple courtrooms, impacting both companies' legal expenses and market strategies.
Q: What was the ITC's preliminary ruling about?
A: An ITC judge ruled that Apple's redesigned watches, which were modified to bypass a previous ban, do not infringe on Masimo's blood-oxygen sensor patents.
Q: Does this ruling end the dispute between Apple and Masimo?
A: No, this is a preliminary decision. It must be reviewed by the full ITC commission, and several other related lawsuits between the two companies are still ongoing.
Q: Which Apple Watch models were affected by the original ban?
A: The original import ban targeted the Apple Watch Series 9 and Ultra 2 models due to their blood-oxygen measurement features.
