Quick Post
I'm just travelling around a bit at the moment and I'm unable to format or research these patents thoroughly. I'm sure some of you will tear it apart. A better translation would be appreciated.
This Japanese site has posted some Canon patents he/she has found.
This is a direct email quote
Based on his investigation Canon made following patents.
EF300/F4 IS II with plastic lens.
http://egami.blog.so-net.ne.jp/2009-12-17

This would be a welcomed lens by many.
EF70-210/F4 IS II with plastic lens
http://egami.blog.so-net.ne.jp/2009-12-12

Not sure this lens needs an update yet.
EF300/F2.8 DO IS and EF 400/F4 DO IS with new double DO and IS
http://egami.blog.so-net.ne.jp/2009-12-02

A lot of DO patents popping up. A lot of people ask for smaller and lighter lenses.
EF 15-24/F3.5-4.5 Fish eye zoom (not EF-S)
http://egami.blog.so-net.ne.jp/2009-11-27

I think this would be a great fisheye solution. It wouldn't cost a lot at first sight.
CR's Take
All make some sense outside of a new 70-200 f/4L IS.

Hey, he’s got his priorities in the right place, regardless of the type of parties he goes to!
Or if you are physically disabled and can’t lift such heavy lenses…
Why else would you blow all that money on lenses!? haha
