Dr Huang does not own the patent anymore. Ocean Tomo Federal Services
LLC does, unless if they've sold it off. I do not believe he can give
you a license to the patent. His opinion about what can be done
without acquiring a license to the patent is in conflict with US law.

Sorry, I'm afraid not. I believe the current law of the land was laid
out in Madey v. Duke which interprets "commercial use" *extremely*
broadly. Universities charge tuition and take in research grant money,
and using patented inventions without paying royalties would make a
university's program more attractive, both from students paying
tuition and granting agencies, than otherwise. That was enough of a
commercial nexus for that judge. It also draws on previous cases that
limit the experimental use defense to cases where the use is "solely
for amusement, to satisfy idle curiosity, or for strictly
philosophical inquiry". University research programs are anything but
idle curiosity, I'm afraid. The Supreme Court declined to review the
case, leaving it the controlling precedent nationwide, and it has not
been overruled to my knowledge.

Here is the decision, edited down to the juiciest bits:

Sure. You can write open source software that includes patented
inventions. Users of that software have the responsibility to
independently acquire a license for the patent. The fact that academic
users have long ignored that responsibility just shows their ignorance
of the law (and I don't entirely blame them since it's complicated);
it is not a reflection of the law itself.
