Is Apple playing the waiting game? Smartwatches still lack key health feature

While the rumor mill has been quiet, Apple will likely release a new version of the Apple Watch later this year. And those wearables, despite being some of the best smartwatches, will still be missing a significant health tracking tool — blood oxygen monitoring (or Sp02).

It's a feature that Apple Watches in the United once had but has been missing in action for over a year due to an ongoing legal battle over patents.

As of this writing, the feature remains disabled in new Apple Watch Series 10 and Ultra 2 devices sold in the US. A recent "Power On" column by Bloomberg's Mark Gurman suggested that Apple is in no hurry to bring it back.

As he writes, Apple isn't settling the lawsuit, nor does the company appear to be building a version of the feature that gets around the disputed patents.

A brief timeline

And that's where we stand now. For those who bought an Apple Watch before January 2024, you still have the Sp02 feature, but anything sold since then including the Series 9, Series 10, and Ultra 2 lack the tracking metric.

Early last year, CEO Tim Cook's public stance was that Apple would focus on appealing the ITC ruling rather than licensing from Masimo.

While lawsuits can be protracted and bogged down in legalese, it's surprising that Apple's strategy appears to be to wait it out.

Especially since several competitors offer the same or a similar feature including Samsung's Galaxy Watches, Google's Fitbit devices, Garmin watches and the smart rings like the Oura Ring 4 or the Samsung Galaxy Ring.

Why is Apple waiting?

As mentioned, Apple's public stance so far is to appeal the ITC ruling.

Tom's Guide looked up the two patents that Masimo is claiming Apple infringed with its blood oxygen tracker.

The patents — US 10912502B2 and US 10945648B2 — are largely about ways to noninvasively track "various blood constituents... such as glucose."

Both patents are expected to expire on August 25, 2028. It's possible that Apple is waiting for the patents to expire. This would be a strange strategy, though, considering how quickly tech moves. 2028 is three generations of watches from now, and the space could be wildly different then.

Beyond that, our understanding is that Masimo could "extend" the life of the patent by filing patent applications for improvements and modifications. Though the changes need to be considered "non-obvious." By 2028, will they need to?

Tom's Guide reached out to Apple for comment and will update if the company responds.

Meanwhile, the clock is ticking.
