Stinson Leonard Street Expands Operations in St. Louis

Press Release

Stinson Leonard Street LLP and St. Louis intellectual property firm Senniger Powers LLP announced today that they have agreed to combine. The combination will strengthen Stinson's St. Louis presence and expand its intellectual property practice. The attorneys and staff from Senniger Powers will join Stinson effective October 1, 2018.

"Senniger Powers has a long-standing history as a prominent intellectual property firm in the St. Louis region and beyond," said Mark Hinderks, Stinson's managing partner. "Their attorneys and patent agents offer the business community a robust combination of scientific, technical and legal experience to deliver effective solutions to achieve clients' business objectives. This expansion will augment our already strong market presence, bringing us to 75 attorneys in Clayton, and will add breadth and depth to our ability to provide market-leading IP services to our clients."

Senniger Powers focuses on intellectual property, helping clients ranging from Fortune 500 companies to start-ups achieve competitive advantage through the strategic management of their IP portfolios. The firm focuses on the preparation and prosecution of patents, copyrights and trademarks, and related litigation, in industries such as life sciences, pharmaceuticals, manufacturing and software. Most of the attorneys are engineers or scientists with advanced degrees and deep experience in a variety of technical fields.

"We are excited for the opportunity to grow our resources in the St. Louis market and to expand our national reach," said Kurt James, managing partner at Senniger Powers. "Our clients will greatly benefit from Stinson's depth of experience in numerous practices and industries as well as cross-market collaboration."

The Senniger Powers attorneys and staff will move from their current downtown office to Stinson's Clayton office over the coming months.

Stinson's combination with Senniger Powers continues the firm's growth strategy. In June 2018, Stinson added new offices in both Dallas and Denver. The new Dallas location expanded the firm's business litigation practice and established a base for the firm in Texas. In Colorado, Stinson is one of the few law firms with multiple locations, offering the flexibility to serve clients from its downtown or Denver Tech Center locations.

Stinson is a full-service AmLaw 200 firm with nearly 500 attorneys in 15 U.S. locations. The firm represents clients in multiple industries, including financial services, energy, health care, real estate, transportation and technology. Stinson has an innovative distributed headquarters operation, with substantial offices in Kansas City, Minneapolis, St. Louis, Phoenix, Denver, Wichita, Omaha, Washington, DC and Dallas.
