Patents and trademarks

I am not a patent attorney. Before becoming a patent attorney, the person must be an engineer. However, patents and trademarks can overlap the subject of their protection. I suggest reading Erik J. Heels' Patents vs. Trade Secrets for anyone interested in reading up on this overlap. It isa few years old but I notice nothing out of date when I re-read the article last night.

What do I when a client has a patent issue? Anderson has a patent attorney that I will work with.
