I shall now make some rubbish up.
Allistair mentions that geostationary orbits, always on connection, are at 36,000Km. He also mentions that Wyld LEO satellite[s] orbit at 700Km.

I would trust Casio.
The calculator suggests that the orbital period is about 1Hr and 40Minutes.
Then you get to stick your thinking hat on and wonder why this is good for a, low bandwidth, system like Lorawan.
There are serious constraints placed on transmit time and time slices within the available license free bandwidths.
However if a sensor is only collecting and storing minimal data over a, for example, 24 hour, period then seeing a satellite once will be enough to burst offload such a minimal payload.
Based on the above mumble a 'sensor' will see a satellite every 1Hr 40Minutes but it wont. You also have to consider the Ground Track of the satellite,
https://en.wikipedia.org/wiki/Ground_track
Basically within a 24 hour period our LEO satellite will make 12 orbits with each orbit covering 30 degrees of the Earths surface hoovering up sensor data as it goes along and this fits in with the transmit/slice time available from Lorawan as long as you mediate between the sensors and the satellite.
It's not exactly 100% but it is close.
It may be the case that Lorawan or its standard is or could be made adaptive.
Given Wyld is going to be covering sp****ly populated, in terms of people and sensors, areas the amount of data collected per pass may be subject to relaxation of the protocol, again subject to proper mediation, to get more throughput without incurring interference penalties.
To end my burble.
The failing patent does not matter. If my stupid blither is correct and Wyld are first to market with an implementation that aligns with my stupids and the backup from their partners then that is or should be exceptionally encouraging.
