#5 Trademark & Patent Filing: Week Ending 5 November 2026

This is a weekly roundup of new trademark and patent filings from the sports watch and sensor brands this site covers. Trademarks come first, because a registered name usually becomes a product or feature and the name itself is often the clue. Patents follow as evidence of direction, and most never reach a product.

Other sites push out an alert for every patent and trademark the moment it is published. This roundup gathers the week into a single read and keeps your inbox clear. The weekly Deep Dive Digest email covers the wider sports technology news for those who want it.

Also in the Deep Dive series: Regulatory Filing, Legal Files, Fix Files, Feature Files and the Deep Dive Digest.

No new in-scope trademarks surfaced this week, so the roundup rests on patents. The most notable are a granted Oura patent on illness detection from ring temperature data and three Polar applications covering warm-up coaching, SpO2 emitter layout and circadian adaptation.

Trademarks

No new trademark filings from the brands we cover were found this week.

Patents

Polar: a smart coach that plans your warm-up

Published on 29 October 2026 under the title Apparatus for Warm-up Smart Coaching (US 2026/0341178 A1). The title indicates a system that prescribes or guides a warm-up for a session. We could not open the full record, so the claims are unread.

If it ships, a Polar watch could set a warm-up routine matched to the session planned that day, rather than leaving the choice to the athlete. For racing, that would be most useful before intervals or a time trial, where a poor warm-up costs the first efforts.

Evidence: Patent application published, not independently checked. Likelihood: Possible. Source: uspto.gov, reported from around the web

Polar: a different arrangement of SpO2 light emitters

Published on 29 October 2026 as SpO2 Emitter Arrangement (US 2026/0334826 A1). The title points to the layout of light emitters used to estimate blood oxygen at the wrist. The record itself was not opened.

A better emitter layout could make blood oxygen readings steadier during movement and at altitude, which matters for athletes training or racing in the mountains. Polar has not said whether any watch will use it.

Evidence: Patent application published, not independently checked. Likelihood: Possible. Source: uspto.gov, reported from around the web

Polar: adapting your schedule to your body clock

Published on 29 October 2026 as Circadian Rhythm Adaptation (US 2026/0334874 A1). The title suggests guidance for adjusting sleep, light or activity timing, perhaps for travel or shift work. The abstract was not read.

For an athlete crossing time zones to race, the feature would suggest when to train, sleep and seek light. Such guidance already exists in basic form on several platforms, so the novelty is unclear.

Evidence: Patent application published, not independently checked. Likelihood: Possible. Source: uspto.gov, reported from around the web

Oura: spotting illness from ring temperature data

Granted on 3 November 2026 as Illness Detection Based on Temperature Data Measured via a Wearable Ring Device (US 12,778,515, application 17/357,922). The title describes detecting illness from skin temperature trends measured by a ring. We could not open the record to read the claims.

Oura already offers temperature-based features, so a granted patent more likely protects existing work than signals a new product. For an athlete, an early warning of illness can justify cutting a hard session before it becomes a longer layoff.

Evidence: Patent granted, not independently checked. Likelihood: Possible. Source: uspto.gov, reported from around the web

Oura: biofeedback guided by heart rate

Published on 29 October 2026 as Techniques for Biofeedback Using Heart Rate Data (US 2026/0341516 A1). The title indicates live feedback to the wearer based on heart rate, probably for relaxation or breathing. The abstract was not read.

A ring that guides breathing from your own heart rate could help with downtime between sessions and with pre-race nerves. It would sit closer to recovery than to training itself.

Evidence: Patent application published, not independently checked. Likelihood: Possible. Source: uspto.gov, reported from around the web

Ultrahuman: a ring tuned to optical sensor readings

Granted on 3 November 2026 as Electronic Ring for Optimizing Health and Fitness Parameters Measured by Optical Sensors (US 12,778,451, application 19/038,017). The title describes a ring whose design or processing improves optical sensor measurements. The record was not opened.

Optical accuracy on the finger is the main weakness of rings during hard exercise. If the patent covers a real fix, heart rate during intervals could become more dependable, though the title alone does not show that.

Evidence: Patent granted, not independently checked. Likelihood: Possible. Source: uspto.gov, reported from around the web

Samsung: the structure of a ring-type wearable

Granted on 3 November 2026 as Ring-Type Wearable Electronic Device (US 12,783,008, application 18/430,032). The title is broad and the detail of the claims is unknown because the record could not be opened.

Samsung already sells the Galaxy Ring, so this probably covers the hardware of a current or later model. Athletes should treat it as evidence that the product line continues rather than as news of a feature.

Evidence: Patent granted, not independently checked. Likelihood: Possible. Source: uspto.gov, reported from around the web

Google: better biometric sensing in a wearable

Published on 29 October 2026 as Wearable Computing Device with Improved Biometric Sensor Function (US 2026/0334877 A1). The title is general and the record was not opened, so the actual change is unknown.

Any gain in sensor quality on a Pixel Watch or Fitbit would matter most for heart rate during running and cycling. The patent gives no indication of timing.

Evidence: Patent application published, not independently checked. Likelihood: Unlikely. Source: uspto.gov, reported from around the web
