According to the information, the PC-E 17mm f4 will have a length 188.3mm. Quite a monster! (vs the 107mm for the Canon's TS-E 17mm f4)
If the 188mm length is not a typo, then I wonder how large the front lens element will be, and then how much the weight/price will be.
The new patent for 28mm f1.4 is understandable. The one for 30mm f1.4 is quite a surprise: Given the 28mm f1.4 and 35mm f1.4, I don't understand why people need a 30mm f1.4. Or, will it a DX lens?
Is the 24mm f1.4 patent for the exsiting 24mm f1.4 or a renewal???
There is yet a patent for 10mm f4. It is unclear will it be a DX or FX lens.
It appears that Nikon is putting a lot of efforts in upgrading/improving its (U)WA lineup.

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.
