Deep specialisation in the IP vertical and an all-encompassing patent skillset distinguish Buchanan Ingersoll & Rooney from most of its general practice competitors. With a total command of all aspects of prosecution, litigation and patent commercialisation, the collaborative group lets nothing slip through the cracks and ensures that opportunities are never missed. The strength and quality of its patent prosecution skills give the practice extremely strong foundations, which further enhance the undoubted quality of its contentious offering. Individuals here aren’t siloed, creating the ideal conditions for companies to capitalise on their outstanding versatility. Chemical group co-chair Duane Stewart, for example, prosecutes, manages portfolios and litigates with poise, showing a deft touch on international matters. He supports a top university alongside Lynn Alstadt and Ralph Fischer, helping its licensing officers and inventors to obtain valuable patents at home and abroad. Alstadt draws on her encyclopaedic knowledge of patent law and contemporary understanding of technology to dispense essential strategic advice and advocate in numerous litigation forums. Steeped in all aspects of intellectual property, Fischer is also a dab hand in many technical domains. Cut from similar cloth, Michael Dever is another major draw for the group: recommended on each of the prosecution, litigation and transactions tables, he’s a true patent polymath. Though active across diverse theatres of innovation, Dever is a trained chemical engineer with a penchant for chemical matters; these are likewise a forte for Craig Cochenour, a past leader of the firm’s pharmaceutical industry group and a former in-house counsel who neatly tailors his service according to need. David Gurwin and Susan Hartman, meanwhile, are the ensemble’s sharpest IP transactions lawyers. Gurwin’s recent licensing activities have included representation of a professional sports team, a playwright, an autonomous vehicle technology company and an international pharmaceuticals manufacturer; this diversity exposes him to issues across the spectrum, further honing his exceptional problem-solving abilities. Hartman partners closely with client teams and is a repository of trust on the most commercially significant matters.

With many former USPTO examiners among its 45 registered practitioners – who collectively have nearly 7,000 patents in active prosecution – Buchanan maintains a rich and vibrant procurement and opinions practice. An added specialisation in post-grant proceedings and litigation gives it the feel of a boutique, but one that offers the advantages of a full-service outfit. The firm has a new face on the prosecution listings this year in Shawn Cage, who co-chairs the electrical group. He acquits himself with distinction supporting the portfolio development of Mastercard Worldwide, a client for which Buchanan’s broad IP horizons are a major boon. Cage does this alongside IP co-chair Charles Wieland, an attorney who guarantees efficiency, cost effectiveness and above all quality. Wieland has an impressive record at the PTAB, too – one which rivals that of top specialists in the group. Taking the lead on mechanical matters, meanwhile, is William Rowland, a stalwart of the practice who has instilled a client and quality-first mentality in the group. Steeped in post-grant know-how – he is an authority on interferences – sophisticated strategist and advocate Todd Walters heads the USPTO contested proceedings practice, working alongside other high-level contributors including Patrick Keane and Matthew Fedowitz. A percipient patent strategist, Keane understands how to use litigation and America Invents Act (AIA) proceedings, among all other available tools, for the purposes of IP value creation. Fedowitz’s duality as a prosecutor and litigator gives him a skillset fit for successful PTAB representations. For Lloyd Smith, who has fought and won cases in all IP categories, court litigation is the name of the game. He and Fedowitz have teamed up on a number of pharmaceutical cases, giving his recent patent activities a strong life science bent.
