Here is the actual text of the written office action (page 8):
3. Claims 1-20 are allowed
The prior art taken either in singularity or in combination fails to anticipate or fairly suggest the limitations of the independent claim 1...
I have filed plenty of patents before, and I never had such a letter approving all my claims. As claim 1 reads, my invention applies to any kind of flexible powerline that can move like a train inside a pipeline conduit. That means that 100 km sections of MIND cable can be unwound off a ship directly into the conduit; if such a cable is transported by robots that carry the cable, that is an embodiment of my invention. To visualize how that will work...think army ants with the cable on their backs. The installation and rapid repair method works for superconducting lines, though the minimum bend radius for different superconductors varies a lot.
