Asobinet, who spotted the patent, says [google translated]:

Looking at the lens configuration, it is very similar to the 18-50mm f/2.8 DC DN (not 100% match). Perhaps F2 zoom was one of the options during the examination stage of practical use lenses. However, now that F2.8 zoom has appeared, it seems unlikely that F2 zoom will see the light of day.
