Attention patent lawyers: How many of your clients tout their patented or patent pending technology How many of their products are marked with one or more U.S. patent numbers

Here on my desk, I see at least three products that are marked with patent numbers laptop, insulated coffee cup and mp3 player. My in-box contains a brochure advertising a patented system, and when I checked my personal e-mail, I saw an ad for a patented energy supplement that, come to think of it, may be just what I need.
