Is a pulse oximeter patented?
Short answer: specific designs of a pulse oximeter have been patented many times, but "a pulse oximeter" as a general idea is not what is protected. What matters is the exact combination of features in your version.
What our index shows
- 640 US and WO patent publications since 2000 have a title matching “pulse oximet” or a close variant (our index of 9.7 million patent families; one publication per family).
- Among the 427 best keyword matches we examined, 136 were published in 2020 or later, and the earliest was published in 2000.
- Most frequent assignees in those matches: KONINKLIJKE PHILIPS NV (28), MASIMO CORP (25), COVIDIEN LP (13), DATEX OHMEDA INC (12).
- Most common patent classes (CPC subclasses): A61B (419), G16H (35), A61M (14), G01N (12).
Counts come from keyword matching on titles and abstracts, so they are indicative, not a legal count. Some matches are different products that share a word.

What this means for your idea
Because patents cover specific combinations of features, the useful question is not “has a pulse oximeter been patented?” but “has my combination of features been described before?” Health and fitness devices are dense with sensor and wearable patents; compare the sensing method, mounting, and what feedback is given.
