My attention has been drawn to US patent #us11411513b2. This is a granted patent for a free energy device. I thought this nonsense had been stopped after Robert Park kicked up a stink about patents that fall foul of the laws of physics being granted.

It's questionable the patents that are granted on the basis of being a new invention, I do not understand how Dyson did it given that he states the idea was given to him when he saw the dust seperation at a sawmill. I suppose the trick is to get a patent and then make someone else prove it invalid at the cost of all the legal fees.

You can't patent a principle. Nor, in the civilised (non-USA) world can you patent a discovery. All Dyson's patents are "a means of...." doing something, and a patent is only granted if the official examiner considers it to be truly original. So whilst centrifugal separation cannot be patented, the design and construction details of a particular device for extracting domestic dust from carpets can be.
The cost of invalidating a patent is negligible: you only have to show evidence of a prior disclosure, and the best evidence is another registered patent, which is in the public domain! The big cost is in defending a patent against unauthorised copying.

US patent #us11411513b2.
is not a free-energy device but
A method for providing electrical power to an electricity distribution grid by operation of a self-sustained nearly frictionless and near perpetual maglev generator started from an external power or battery source, said method comprising:
in other words, a very complicated flywheel.
