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

300f41 - Lens Patents
EF 300 f/4L IS II

This would be a welcomed lens by many.

EF70-210/F4 IS II with plastic lens

70210 - Lens Patents
EF 70-200 f/4L IS II

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

30028DO - Lens Patents
EF 300 f/2.8DO IS

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

fisheye - Lens Patents
EF 15-24 f/3.5-4.5 Fisheye

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.
