Masimo sues Apple over Apple Watch patents, alleged theft of trade secrets
Medical technology company Masimo on Thursday filed a legal complaint claiming Apple infringes on 10 owned patents with its Apple Watch device, and stole vital trade secrets through the hiring of key personnel.

Lodged with the U.S. District Court for the Central District of California, the suit alleges Apple Watch, including the latest Apple Watch Series 4 and Series 5 models, leverages technology covered by ten Masimo patents. Specifically noted in the case is intellectual property detailing Apple Watch health features like heart rate monitoring.
According to the filing, Masimo is a pioneer of non-invasive physiological monitoring techniques having developed a wide range of technologies to track patients' pulse rate, arterial oxygen saturation and other parameters using nothing more than transmitted light.
In particular, Masimo invested heavily in the evolution of photoplethysmograph, or PPG, technology. While exact methodologies differ, PPGs at their most basic level sample readings from light transmitted into, and subsequently reflective off of, body tissue. Results can then be obtained by calculating attenuation of light from constituents in the human body, specifically blood.
The company's Signal Extraction Technology (Masimo SET) solved a variety of problems that plagued traditional PPG hardware, improving reliability and accuracy of reporting of physiological signals derived from the PPG, the suit reads. Masimo went on to develop other non-invasive technologies measuring total hemoglobin, carboxyhemoglobin, and methemoglobin.
In 2013, prior to the launch of the original Apple Watch, Apple approached Masimo with a potential deal that would integrate the medical firm's technology into an as-yet-unreleased product. Following what appeared to be fruitful initial talks, Apple stepped back and in 2014 began to hire key Masimo personnel including former Chief Medical Officer and Executive Vice President for Medical Affairs Michael O'Reilly and Cercacor CTO Marcelo Malini Lamego. The tech giant has adopted identical strategies in the past.
Cercacor is an offshoot of Masimo, having been spun out from the main company in 1998 as "Masimo Labs" and later renamed. While the two companies share a cross-licensing agreement, Masimo does not own Cercacor.
Masimo and Cercacor warned Apple about potential legal violations, but the iPhone maker went on to pursue patent applications covering topics similar to those already patented by the medical technology firms. Lamego, named as an inventor on many of these patents, was "intimately involved" in the development of corresponding technologies at Cercacor and Masimo, suggesting the executive aped the sensitive IP on behalf of Apple.
In addition to infringement and trade secrets claims, plaintiffs seek correction of inventorship on five patents, the subject matter of which Lamego allegedly obtained from discussions with Masimo or Cercacor employees Ammar Al-Ali, Mohamed Diab and Walter Weber. The suit claims Al-Ali, Diab and Weber are inventors of the IP "regardless of patentability."
Masimo seeks an injunction against Apple Watch Series 4 and Series 5, damages for patent infringement and theft of trade secrets, and court fees, among other relief.

It is not illegal to hire engineers from other companies and if they don't bring your patented IP to the hiring company, you have no case.
Masimo's only hope is to argue that the Apple patents are invalid but they would likely lose.

There’s nothing wrong with ‘aping,’ other than the term being a bit Victorian. An inventor of technology obviously has deep knowledge of the subject matter, it’s his area of expertise. If Cercacor and/or Masimo had non-competes in play with Lamego and he went to Apple to work on competing technology during the period when those non-compete agreements were in effect, then pursue that legal avenue. But otherwise he has the right to make a living utilizing his area of expertise. And ‘aping’ as they refer to it may be exactly how patented technology advances. You start with a great idea, that someone else has patented, and you modify it to both make it better and to change the method utilized sufficiently to avoid infringing the patent. Done all the time.
There's so much supposition following "You start with a great idea..." I can't even begin to address any of it. Seems to be a fair bit of unreality.
If Apple was issued patents, and products were made off those patents... Masimo is going to have to prove those patents were invalid.
Or 1. They could be waiting to sue those guys later (like Sonos suing Google instead of Goggle and Amazon because they can only afford to sue one at a time)
Or 2. The other guys could have licensed Masimo IP
Or 3. Garmin, Fitbit, Samsung, and Fossil secretly formed a Cabal and are secretly bankrolling Masimo's lawsuit against Apple in the hopes of gaining an embargo on the Apple Watch so their smartwatches have a chance of gaining a foothold. Moments before the judge renders a verdict in favor of the cAbal, the trial is interrupted with the bombshell info that the entire trial has been a conspiracy against Apple and the Apple Watch. As the judge rules against the caBal, a Samsung Ballie rolls slowly into the courtroom and shoots darts into the necks of the cabAl members so they can't turn against each other. Which means someone was controlling the cabaL. dun-dun-duuuuuunnnnn.
Not gonna lie. Sort really hoping for option 3.
a move in from of the monkey cage and the monkey imitates that move. There’s no theft involved.
How can an employee get another job without mentioning his/her experience and knowledge?
What’s the line?
They're suing for infringement... on 10 patents. You trying to reframe it as if the employee issue is the focus doesn't even make sense. So no, I'm not suggesting someone not do the right thing. I am suggesting you should probably refrain from trying to shift the focus to the ancillary issue.
You're making assumptions and building elaborate narratives around them. Can't really argue against your imaginings. You're wrong by the way. There's a ton of fanboyism in your supposition. You even get so fanboy'd that you go off on a tangent about shorting stock and doomed organization and your position on AAPL All three of those are classic fanboy staples. I don't even wanna...
In all your musings, it never seemed to occur to you that Apple could have simply calculated a cost/benefit analysis that an infringement verdict would cost less than the gains in using the IP. If it ever even came to that. That's something companies do all the time.
We agree that words have meaning. That's why I chose the ones I chose and more importantly, placed them where I did. Please don't remix my words.
I see this and decide to ‘ape’ your patented work, but I’m going to do so using lightweight sensors and a computer controller to provide exactly the same valve timing under the same conditions. Have I copied? Or have I imitated (aped)? And am I in infringement of your utility patent?
I'm not sure what the hang-up is. But I'm sure there is something otherwise Apple (and others) would have already implemented it.
