There are not 3 separate patents, one patent covers the 24, 28 and 30mm f/1.4 (as well as a 28mm f/1.8). The patent was applied for in September 2010.
The 10mm f/4 is also part of the same patent as the 17mm f/4 and is an FX lens.
(These details are all available in both links you posted!)
Anyways, patents are not a reliable indicator of coming production. It's kinda like staking a plot of (intellectual) land, it doesn't mean that a house will be built on it.

Yes, I see. The AOV of a TS 17mm is close to the AOV of a FX 10mm so they can have the same lens configuration. So if a TS 17mm is possible, a FX 10mm is also possible (at least in theory).
The patents were applied for in 2010 so the production of a PC-E 17mm f4 may not be far away.
