Research Help: How many patent attorneys sit on corporate board of directors?

Help! 

I know the erudite readers of PHOSITA may have valuable information I need:

I am working on article regarding the makeup of corporate board of directors and I am trying to get a sense of how many patent attorneys are directors.

If you know of anyone or have a suspicion, please send it my way.

Thanks and hopefully this will be picked up around the IP corner of the blog-o-sphere... hint, hint, hint, hint, hint, hint...
