This is a bit of misdirection. This is a patent issue not a stolen IP issue.
What’s the difference? IP is secret. Patents are public. Published by the Government for all to see.

This would lead the reader to believe that the issue at hand is Apple was trying to steal secrets from Masimo.

The issue at hand is a patent violation: Apple using Masimo patents in its product. Masimo claims 5 patents were infringed ( used without permission or licensing ). On Jan 10th, the Judge found that Apple had indeed infringed on a Masimo Blood Oxygen Patent.
