Client Comments ...

" ... both [a sophisticated and complete view of the technology and our prior-art disclosures] were important factors in getting to the dismissal, and you made important contributions on both fronts." Partner at leading San-Francisco AM Law 100 firm.

"What you do is fairly unique ... Your level of engagement, I can't say that I actually have [seen it elsewhere]. ... What you offer are very technical and, in depth, investigative exercises, which are very difficult to get in my prior experience, very difficult to get someone to really put in the effort to learn the ins and outs." VP of Engineering at a leading-edge pulse laser systems company and, earlier, at a routing systems company.

"Your perspective both from the engineering/technical point of view and ... the market is very, very useful and quickly narrowing down what the areas of focus should be and prioritizing what should be worked on, given the resources that different organizations have [is critical] ... which is what you have established yourself for." Distinguished Engineer and Chief Software Architect at a top-vendor of switching and storage gear.
