Pauly, DeVries Smith & Deffner

What Pauly, DeVries Smith & Deffner does

Pauly, DeVries Smith & Deffner (PDSD) is a Minneapolis-based intellectual property and technology law firm founded in 2005 that specializes in patent prosecution services for businesses and entrepreneurs. The firm serves a dual market of early-stage ventures seeking to protect innovations and large enterprises requiring ongoing patent portfolio management, with a stated emphasis on 'IP-savvy, serial patent filers' who value standardized, efficient processes. PDSD's team combines legal expertise with diverse technical backgrounds spanning chemistry, software development, mechanical engineering, physics, biochemistry, and molecular biology, enabling prosecution across chemical, biological, mechanical, electrical, software, semiconductor, and medical device technologies.

The firm operates through three core service lines: U.S. Patent Services (domestic preparation, filing, and prosecution), International Patent Services (coordinated global prosecution through a network of international IP law firms), and Patent Investigations + Counseling (patent searches, patentability and infringement opinions, portfolio management, freedom to operate analysis, and IP due diligence). Supporting these services is PatFlow, a custom-built firm-wide software tool that provides real-time kanban-style visibility into U.S. and foreign patent matters including deadlines, progress, and budgeting. The firm has implemented Lean practices throughout its operations, standardizing over 60 common procedures for patent prosecution work and adopting a claims-first drafting methodology designed to reduce costly rework and minimize in-house counsel revision time. The firm has also developed in-house competitive intelligence software tools to monitor and evaluate clients' competitive landscapes.

PDSD generates revenue through traditional professional services fees — billable hours and/or fixed fees for legal services rendered — with client acquisition driven primarily by referrals, professional networks, and direct engagement rather than formal marketing channels. The firm operates from a single Minneapolis headquarters at 121 South 8th Street, Suite 900, and serves clients globally through its international IP law firm network. No public revenue disclosure exists, and the firm maintains a private LLC structure with no external investment or parent company ownership indicated in available data. The founding partners — Mark E. Deffner, Kate DeVries Smith, and Daniel M. Pauly — continue to practice alongside additional attorneys, a patent agent, paralegals, and administrative staff.
