A patent lawyer is like an oil painter, it takes a lifetime to get good, and you can’t rush it. Big firms do not offer any advantages for producing quality patents (which are equivalent to oil paintings). The artist is the key. Big firms, like the extinct Darby & Darby 100 patent lawyer firm pictured, can provide a team of ten lawyers for a lawsuit, but that is not what we are talking about. Many small patent firms have good artists, we are one of those small patent firms that has produced over 500 patents ( key Rick Martin into Google Advanced Patent phrase search ).
We offer less than half the cost of a big firm for patent prosecution. Rick’s engine control patent is currently asserted against Harley Davidson. Quality is quality.
