Just to clarify what this may or may not mean -- this relates to a patent application that was filed December 2010 (not an issued patent). Patent applications generally get published 18 months after filing. So, that's what this is. The takeaway is that about 18 months ago engineers at Canon thought up this design, and someone made the decision that it was worth pursuing patent protection for. Whether that will translate to a new lens, and when, we can only hope. By the way, to put things in perspective, since 2001, Canon appears to have filed over 25,000 US patent applications.
