I think it is a bit unfair as a policy, unless then used those patents themselves. While not ideal, right now it would be silly not to attempt to register defensive patents given the resources to do so.
I don't search to see if you've ever filed for one, but putting it on your resume to me says that you want to work for a company that promotes them. The day may come when I have to file defensive patents of my own, but I'll never brag about it.
And as jongraehl said, there's still one strike left :)
