Client Testimonial

Wolf Greenfield’s Post-Grant Proceedings Practice features a team that’s unparalleled in its ability to pick apart technically complex cases to plot a path to success. The team quickly distills cases down to key technical issues to develop and present winning arguments. Moreover, working with Rich and Elisabeth in particular is a pleasure: they are highly responsive, engaging, and tenacious. I highly value and trust their judgment and work product.
