It’s a well documented problem that many groups have tried various technical approaches to mitigate over 100,000 hour operating windows.
It’s not too surprising that a particular implementation that has various benefits compared to the existing state of the art would be patentable.
Isn't the point that a patented process is documented as part of the patent application? Industrial processes and materials seem like a great use of patents from my POV. Psychology and biology I'm more concerned with.
