That can be a sign that they have given up on it. The problem with patents is, that your competition is studying them as well and knows what you are up to. As a result things are often carried to the patent office once you don't want to do it yourself any more.

That reasoning means there will not be a Canon Ef 14-24mm L f2.8, nor an EF 24-70mm f2.8 L IS USM <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='Big Grin' /> (among others)
