Polar quietly filed for a new metric on October 16, and the name tells you more than the filing does.
The application is for MOMENTUM SCORE, filed with the European Union Intellectual Property Office as EUTM 019436943. It is a word mark, filed by Polar Electro Oy of Kempele, Finland, and it currently sits under examination. No announcement, no product page, no hint in Polar Flow.
We checked the register directly rather than taking the filing secondhand. The goods and services text is the part worth reading closely.
What Polar Actually Asked For
The application covers two classes, and neither one is about hardware.
Class 9 covers downloadable mobile apps for gathering human biometric data, "measuring or recording or analyzing different physiological data, biosignals and exercise parameters," software for syncing exercise data between devices, and electronic equipment for providing training instructions. The filing ends with a line that matters: all of the above not for medical purposes.
Class 41 covers educational and instruction services relating to exercise, coaching services for exercise activities, and education services relating to customer satisfaction.
So this is a software and coaching mark, not a watch. That matters, because it means Momentum Score is most likely something Polar's platform calculates from data it already collects, rather than a feature that needs new sensors in a new watch.
Why "Momentum" Is a Strange Word to Pick
Polar is not short of scores. The Vantage V3 page alone lists Training Load Pro, Nightly Recharge, Recovery Pro, FitSpark, SleepWise and Serene. Every one of those is a snapshot of a state. How hard was the session, how did you recover overnight, what should you do today.
Momentum is a different kind of word. It implies direction over time rather than a reading at a point. And that lines up with what Polar shipped on September 30, when firmware 6.0.18 added seven-day trend graphs to almost every health metric on six watches, from ANS charge to nightly heart rate variability. We covered that release in detail here.
That firmware made a single bad night readable as a dip instead of a verdict. A score built on momentum would be the natural next step: one number that summarises whether the last few weeks are heading the right way.
There is a second reason the word fits. Polar now sells the Polar Loop, a screenless band listed at 179.90 euros on Polar's European store, built for 24/7 wear with no display at all. On a band like that, a numeric score delivered through the app is the product. A metric that rewards consistency, rather than one that demands you look at a watch face mid-session, makes far more sense there than a training-load number does.
The Filing Four Days Earlier
Momentum Score did not arrive alone. On October 12, Polar filed POLAR H12 as EUTM 019434526, also a word mark, also Polar Electro Oy, and also under examination.
We verified that one in the register too. Its classes are 9 and 10: wearable activity trackers and wearable computers with biosignal and motion detection in class 9, and in class 10, wrist devices, monitors, testers, sensors and peripheral devices for measuring physiological data and biosignals including heart rate, heart rate variability, ECG, blood pressure, ventilation, body temperature, body flexibility, body strength and body motion, all for medical purposes.
The H12 name is not new to anyone following Polar's app. It turned up inside Polar Flow 7.36.2 in August, with a dedicated device definition and sensor registration support rather than a leftover string. Our own look at the Flow 7.37.0 build found device profiles for a Polar Loop Gen 3 alongside the H12 details (that article is here).
The current strap in Polar's lineup is the H10, which Polar's own support pages list alongside the H9 and Verity Sense. A trademark for the next one is exactly the step you would expect between app code and a launch.
What We Do Not Know
Plenty, and it is worth being blunt about it.
A trademark filing is a statement of intent. Companies file marks they never ship, and they file defensively. Nothing in the filing says how Momentum Score would be calculated, what data feeds it, whether it would be free or tied to a subscription, or which watches would get it.
On sourcing: Gadgets & Wearables is the only outlet that has written up the Momentum Score filing. We are not aware of a second independent write-up, so the filing number, dates, classes and goods text above come from the EUIPO register itself rather than from any article about it. The H12 trademark has been reported more widely, and the app-code evidence behind the name predates both filings.
There is also a simpler explanation sitting in the same filing window. Polar has a habit of trademarking platform vocabulary around a launch, and two marks in four days suggests a product cycle rather than a random defensive move. That is an inference, not a fact.
What It Would Take to Be Good
Polar does not need another score. It needs one that says something the existing numbers cannot.
A momentum metric is only useful if it disagrees with your gut in a useful way, and only if it can be explained in one sentence. Training Load Pro already tells you whether a week was heavy. Nightly Recharge already tells you whether last night was bad. A score that tracks direction would have to show something like a slow slide that never produced a single alarming night, which is the failure mode recovery scores are worst at catching.
The risk is the obvious one. Add a seventh score to six existing ones and users stop reading any of them.
Bottom Line
Polar filed for Momentum Score on October 16 and for POLAR H12 on October 12, and neither has been announced. The first is a training metric built in software and coaching, which fits a company that just turned its watches into trend viewers and now sells a screenless band. The second is the successor to a chest strap that appeared in Polar's own app code in August.
None of that is a product. It is a filing, a register entry and a name. But two marks in four days is a pattern, and if a Momentum Score does appear, the last month of Polar firmware will look like the groundwork for it.
