I'm SMD blind.
(for an MEE, working at the Max Planck institute, rather amateurish to use colors, imo)
Mr Wurcer, a GEB illuminatus, you ? Shocking !
Yes, some are at the point of unacceptible. They also found popcorn noise due to poor contacts (I presume) on some.
maybe, maybe not. Rohs compliance is not the issue,as the major constituent is not on the Rohs list. The major component, being gallium.
Gallium is considered hazmat due to the fact that as a pure item, it can dissolve or react with aluminum.
Which is pretty horrible for aircraft airframes, which are primarily aluminum. this aspect is the primary issue and source of the extreme hazmat labeling and situation surrounding pure gallium.
The extreme hazmat issue is resolved when things are in an alloy form, so the very vast majority of the capacity for gallium to react with aluminum was dramatically decreased. The gallium is already alloyed with the indium and the tin. Thus the alloy has not the extreme hazmat limitations as the pure gallium.
The company Geratherm, who makes the replacement thermometers, that do not have mercury, but 'galinstan' in them (a specific mixutre or ratio of the three elements-patented and trademarked by Geratherm), Geratherm re-applied to the governing/regulating bodies that are involved in these ratings and shipping issues/concerns. It took about a decade, IIRC, overall, but Geratherm proved to the given standards groups, that the alloy was considerably less hazardous to airframes.
And this earned the alloys of such elements the right to be air-shipped and to not have the extreme hazmat rating of gallium. Once again, the extreme hazmat rating was earned over the aluminum dissolving issue of gallium --alone. Not over, or from, any gallium toxicity issues.
Your issue remains that SOME oxidizing aspects remain within the alloy of the three elements. A very fine, very slightly semi-conductive layer will form at any contact surface, depending on the element involved.
Pure silver is your best choice for contact surfaces, regarding this very minor semi-conductive aspect of the formed oxide layer at the interface point. any layer that forms, is much like the issue with aluminum and exposure to air. Once formed, the oxidation ends.
So, it is possible to build relays with the alloy. However, unlike mercury, your temperature cut off will be higher regardless, with the geratherm 'galinstan' Alloy ratio giving the lowest temperature rating, of -19C, IIRC.
What you will gain, is higher conductivity than mercury, by about a magnitude, IIRC.
to continue (ran out of editing time):
I won't reveal aspects of the patent, but lets just say that so far, at least two groups or people have attempted to 'violate' that concern. One is ongoing, right now. And that one is definitely in violation.
Even though the cables are not well known, the superiority of the conduction and handling of the given signal via this alternative methodology is self obvious, once heard. Alternatively and concurrently... when properly analysed via extreme hardware in a testing lab (with the proper mental analysis applied so results can be found, results of interest)... the differences are found to be fundamental.
The basics are that the signal handling, due to load and drive characteristics, they flip between or ride between being a standard result and methodology, and that of particle to particle quantum function. You end up with quasi-plasma effects and quantum conduction, and thus one could say the cables behave as a 'quantum mass aggregate', with one foot in each world.
Which is well outside of the behavior of any solid, regarding it's interaction with signal, where signal is an ionic quantum situation. Thus the liquid metal cable is simply a different and superior method of signal transfer or conduction. This is indisputable, if time is spent in listening and in technical analysis.
So yes, there really is something new under the sun.

I've seen some data from I think Mitsubishi showing typical differences in excess noise between thick film and thin film parts.
There is also the option of MELF parts, metal film resistors with solderable end caps and no leads. Manufacturing people tend to hate them because they roll off the boards...
Spoilsport!
Actually I'm so negative about the likelihood of a patent being of benefit to the "small" inventor these days (meaning not affiliated with a big-a$$ corporation) that I am siding with Don Lancaster: publish the idea and hope that at least no one will patent it and exclude your use of it. And you may get contacted for a few crumbs of consulting money, by someone who may wish to use the idea.
Just sayin'. Although my friend and former associate in a failed amplifier company, Dan D., disagrees vehemently, and knows a lot more about patent law than I do (while still not qualified to practice law, he will be swift pointing out).
I wonder how that translates into a case with a legitimate suit? One would hope for better, but these days I'm not so sure.
Oh well, time to call the police about the breaking-and-entering event I deduced occurred last night, while I was out for a while. Unsuccessful, although whoever it was managed to damage the lock almost to the point I couldn't get in.
There goes (or, rather, there went) the neighborhood.
Mine was always told that Harry Hannukah was a nice story that only the gullible kids believed.

When the idea is good enough, it may be worth it. I hold one that is still paying for my private research into whatever interests me. Therefore, also small inventors should not be discouraged to put claims on their work. Getting the money is still the hard part, but it can be done.
You should get a criminal record and a bat, works wonders (even better when you insult local cops too on a regular basis)
My neighbors just had electric gates installed on both exits of their estate after the Merc SL AMG got stolen (silly git had the thing parked outside 24/7, +€300k new overhere)
In the "if I knew then what I know now" department, a valuable patent I conceived while a consultant to a large company could have been exploited and I could have worked out a combination of contract compensation along with royalties, as David Griesinger did with Logic Seven. Instead, with no one to push applications, it languishes, the clock ticks away, and it is probably being infringed on at that.
Well it's been a decent place for security going on 23 years now, but "the times they are a-changin' ". The particular apartment will lend itself to more interesting defenses beyond the front door lock, as there is a long hallway. One option is to have a shock opportunity at the second portal at the end of the hallway.
Although it is entirely a hunch, I may have a suspect in the form of a recent tenant, to whom I may have made the mistake of mentioning something of value within, and who, by virtue of his parking adjacent to me can easily determine my comings and goings. And yon Cassius has a lean and hungry look. Such men are dangerous. Maybe.
