Thanks, IVN. I loaded the blog page linked on Nikon rumors in Chrome and translated it (see HERE). There is an example provided that includes size and (if I am reading it correctly) suggests this example lens would be about 9-10 inches in length, which is about double the length of the current Nikon 70-300. The blog page reads:

  • Patent Publication No. 2013-210475
    • Publication date 2013.10.10
    • Filing date 2012.3.30
  • Example 1
    • Focal length f = 72.10-135.70-291.00mm
    • Fno. 4.13-4.5-5.77
    • Angle of view 2ω = 13.0-6.9-3.2 °
    • Image height Y = 8.19mm
    • 229.4-235.8-234.5mm in total length
    • 20 pieces of 13-group lens configuration
    • Six ED glass
    • Three fluorite

At least the length is definitely wrong there. The length of the FX version is 140mm at 70mm FL and 190mm at 300mm FL and I doubt that the Nikon 1 version would be longer, in fact, I'd say it's impossible.
