Northern Virginia-based Oliff & Berridge is an IP boutique with more than 60 attorneys and office locations in Alexandria, St. Louis and Charlotte. Founded in 1983, the firm has experienced significant growth over the years and is now recognized as housing one of the nation's preeminent patent prosecution practices. Attorneys' willingness to work closely with clients, large and small, in order to custom fit services is just one aspect that separates the firm from its peers. The firm's proximity to the USPTO and the large percentage of shareholders who are former patent examiners are also noted by peers as distinguishing factors.
