This guy may be a litigator, but if I were him, I'd hire an intellectual property attorney, because he's basically wrong in many areas. For instance, he states the following:
Additionally, if you are able to identify any of these patents as applicable, please let me know whether Monster Cable presently sells, or has at any time sold, any products bearing connectors which are in conformity with the patent drawings or which are otherwise contended to be within the coverage of the patents, and identify those products for me. Please also provide photographs and/or physical examples of these connectors as manufactured and sold.
For patent infringement, it is largly immaterial as to whether Monster Cable has ever sold any products in conformity with the patent drawings. (I say largly, because damages are harder to prove without sales, but the infringement itself doesn't require products to be sold.) Moreover, Monster doesn't have to provide him with any of the details he's asking for.
Plus, fifty thousand dollars is nothing for a lawsuit involving trade dress and patent claims. Think in the several hundreds of thousands to millions of dollars range. My hourly rate was below $300, and many intellectual property attorneys are well beyond that. Even if one assumes $300/hour, 50,000/300 = 167 hours, which is a mere 21 days. That's way too small of a number of days. A typical case would have one lawyer leading the case, making $500/hour, and one-two attorneys making $250-$300/hour, each of this would work all day for many weeks. That's why many companies settle with these so-called patent trolls rather than litigate.
