Armstrong Teasdale LLP

St Louis-headquartered general practice Armstrong Teasdale showcases an incredibly robust and dynamic patent practice. It puts its cavernous chest of resources at the full disposal of clients, which can call on 55 USPTO-registered professionals and all the technical expertise they could wish for. There’s plenty of prestige work and successes for the group to highlight, including securing a contract from the National Institutes of Health to provide biotechnology patent services and conducting a major freedom-to-operate analysis for a major healthcare company in connection with the US market entry of a medical device. Taking the lead on both matters, Christopher Goff is a superstar of the practice whom innovators praise to the heavens: “Chris gives pragmatic advice and easily navigates complex and nuanced matters, while being highly effective at managing time and deadlines. He has built a hugely capable team that can efficiently handle a great diversity of technologies in the medical device and other areas. Easy to partner with and an excellent issue spotter, he ensures the delivery of a top-quality product.” Equally noteworthy is Daniel Fitzgerald, whose bailiwick encompass prosecution, IP due diligence, patent analysis and more; lately he has run point on numerous IP projects for a global payments and technology company and a premier insurance entity. Fitzgerald is a fitting captain for the outstanding electrical and computer science group. Then there’s Michael Munsell, who consistently performs at a high level for industry heavyweights in aerospace and other sectors: “Distinguished by his exceptional business understanding, Mike is a thought leader when it comes to patent strategy.” The firm also acquits itself with distinction on the litigation side, with Richard Brophy spearheading the most important campaigns. Having gone the distance at trial many times, Brophy is fantastic at sizing up a case and plotting the optimal path to its resolution.

Bryan Cave Leighton Paisner (BLP)

Bryan Cave Leighton Paisner dispenses the full suite of patent counselling, prosecution, transactional and litigation services and, by representing clients through all phases of the product lifecycle, has developed the keenest sense of the business value of intangible assets. Helping to instil this commercial mindset in the team as co-head of the IP group is Daniel Crowe, a litigator who confidently and decisively tackles a wide range of patent, trademark and copyright infringement suits. Hailing from a technical background, he has also proved himself adept at prosecution, making him a superb all-rounder. Another name to note in St Louis is David Roodman, a former leader of the group who continues to set standards as an accomplished IP litigator and transactions lawyer.

Harness, Dickey & Pierce, PLC

One of Michigan’s leading boutiques, Harness Dickey maintains a presence in Texas, DC and Missouri, giving patrons a broad platform to leverage. Stacked with talent, the St Louis team offers impressive coverage, making it ideally suited to the role of IP watchdog for clients. At an individual level too, the folks here are impressively well rounded. Take Joseph Walsh, for example, a former in-house counsel who supports clients at the most meaningful strategic level, whatever might come up. Walsh is at his best on IP commercialisation assignments, but he’s the prototypical trusted confidante. Matthew Cutler is equally versatile: best known as a post-grant ace, he also has buckets of litigation and portfolio management experience. Bryan Wheelock keeps the focus on prosecution and does first-rate work in the mechanical and electromechanical areas.

Polsinelli PC

Richly resourced in both technical and contentious expertise, Polsinelli sees to a sizeable docket of prosecution matters, PTAB proceedings, district court cases and appeals, notching up an eye-catching track record in all endeavours. For sophisticated technology and life sciences entities, there are sure-fire options in the firm’s Kansas City and St Louis offices. Based in the former are Patrick Woolley and Corey Casey, both of whom provide vital support to a major pharmaceutical company for which Polsinelli functions as general IP counsel. Firmwide IP group chair Woolley’s international know-how and proficiency in litigation, licensing and asset management are appreciated by a diverse roster of clients, from Fortune 500s to start-ups and research institutions; having seen so much in the practice, he’s in hot demand as an opinion giver. A doctor of pharmacy and registered pharmacist, Casey adds value as a skilled prosecutor and litigation support lawyer. “Corey’s written work is of the highest quality you’ll see from outside counsel; he can be highly recommended for high-value and complicated patent clearance tasks.” Another standout technologist is Elton Dean, who studied nuclear engineering at the Massachusetts Institute of Technology: “Elton is incredibly sharp and continuously comes up with new and innovative ways for companies to bolster their IP portfolios. He provides timely assistance to inventors and in-house attorneys throughout the prosecution process, and does so with a business-focused approach.”

Stinson LLP

Stinson is a fully specced commercial outfit with nearly 500 attorneys spread across 13 US offices. It has a penchant for complex legal work and gets stuck into IP and technology assignments with enthusiasm and commitment – something that St Louis-based partner Kurt James has been doing for more than three decades. An anchor of the patent practice since the boutique at which he served as managing partner merged into Stinson in 2018, James fulfils the role of counsellor with poise, thanks to his gift for helping innovators make the most of their intangible assets in business.
