That is really neat: “By irradiating the paper with a CO laser, we create refusible, sugar-like reaction products that we use instead of the synthetic materials or adhesives that would otherwise be required to seal the paper by the heat sealing process. In this way, we are essentially producing our own adhesive"
It is but it completely defeats the claimed purpose of bein adhesive free.

The article doesn't tell, unfortunately. Worst case, a cool technical article is the only thing the technology is good for...
Earlier quoted context omitted.
Not if the produced adhesive is free of hydrocarbons, which it is.
The main constituent of paper is wood, which consists of hydrocarbons.
Since Fraunhofer is a notorious patent extortionist, best to not even look at this page.
Can you elaborate on this? My guess would be, that because of their status as a government backed research institute, they invent a lot, but let others do the commercialisation. So patent fees seem like a natural choice for them, to recover their investments.
What could one improve how the operate?

I've also seen a glue-less paper binding trick where two pieces of paper are finely crimped together with some high pressure tool in alternating v^v^v^ patterns, actually making tiny tears in the paper. Does anyone know what kind of tool does that?
Possibly this? https://www.youtube.com/watch?v=_NeGah4YJg0 It's a bit hard to search for, because they make one that punches a hole too (shows up in the video).
You can repeat the process as many times as you want and there won't be any new damage to the paper. With a paperless stapler you would have to do new damage to the paper each time. Also, a regular staple is pretty much forever while these crimped folds can eventually come loose again.
