J.S. Held Taps Defense RF Expert for High-Stakes Wireless IP Battles

NEW YORK, NY – February 05, 2026 – Global consulting firm J.S. Held has significantly deepened its technical bench in the high-stakes world of wireless intellectual property, announcing the appointment of former U.S. Air Force Radio Frequency (RF) systems engineer Dan Sleeter as a Director in its Ocean Tomo Patent Analysis and Reverse Engineering group.

The move signals a strategic effort to bring national security-grade expertise to bear on the increasingly complex and contentious field of commercial patent disputes. Sleeter brings over 15 years of experience leading technical teams across defense, aerospace, and telecommunications, with a specialized background in AI-driven RF programs and secure communications.

A National Security Edge in Commercial Disputes

In the world of intellectual property litigation, where billions of dollars can hinge on the interpretation of a patent claim, technical precision is paramount. J.S. Held's recruitment of Sleeter is a calculated move to gain a decisive edge by integrating expertise forged in the nation's most sensitive defense environments.

Sleeter's background includes work with NSA secure communications, classified RF engineering, and TEMPEST/EMSEC—a discipline focused on preventing compromising electronic emissions. This experience provides a unique and powerful lens for deconstructing modern commercial technologies, from 5G networks to consumer electronics.

"Dan brings a rare combination of national security–grade RF experience, modern AI/ML capability, and hands-on engineering depth," said Tim Dorney PhD, Technical Lead for Patent Analysis and Reverse Engineering at Ocean Tomo. "Our clients rely on us for precise, defensible interpretations of highly complex technologies, and Dan's expertise significantly expands what our team can deliver."

This transfer of skill from the defense sector to commercial IP analysis is becoming increasingly critical. As technologies like Wi-Fi, Bluetooth, and cellular networks become more sophisticated and intertwined, the ability to perform deep, component-level reverse engineering and identify potential infringement pathways requires a level of rigor typically reserved for mission-critical government systems.

Fortifying the Front Lines of the Wireless IP Wars

Sleeter's appointment comes as the intellectual property landscape for wireless technology grows more fraught. The rollout of 5G and the rise of the Internet of Things (IoT) have created a complex web of Standard Essential Patents (SEPs) and proprietary technologies, leading to intense competition and litigation. Navigating this environment requires more than just legal acumen; it demands a profound understanding of the underlying technology.

A key aspect of Sleeter's expertise is his work in applying artificial intelligence and machine learning to RF signal analysis. This field, known as RFML, is at the cutting edge of spectrum management and signal intelligence.

"Dan's background in secure communications, TEMPEST/EMSEC compliance, and classified RF systems engineering directly enhances our ability to deconstruct modern wireless and sensing technologies," added Sam Wiley, Strategic Business Intelligence Team Lead for the group. "His experience applying RF machine learning and automation to spectrum analysis provides a powerful advantage for our clients facing intricate IP and technical challenges."

This AI-driven approach allows for the rapid characterization of signal behavior, detection of interference, and automation of spectrum analysis—capabilities that are invaluable when evaluating patent claims related to next-generation wireless systems. His experience at commercial giants like Verizon Wireless and IoT pioneer Silver Spring Networks grounds this advanced knowledge in the realities of large-scale commercial deployments, giving him a comprehensive view of the entire wireless ecosystem.

A Strategic Move in a Competitive Talent Market

The hiring of Sleeter is the latest in a series of strategic moves by J.S. Held to build a dominant IP consulting practice. The firm has aggressively expanded its capabilities in recent years, acquiring IP specialist firms like Ocean Tomo, TechPats, and IPFC to create a comprehensive suite of services. This growth strategy underscores the immense value placed on intangible assets, which now account for an estimated 90% of the S&P 500's market value.

However, building a top-tier practice requires more than acquisitions; it demands a war for talent. The market for technical experts who possess both deep engineering knowledge and an understanding of the IP landscape is fiercely competitive. Individuals with Sleeter's unique combination of defense, commercial, and AI experience are exceptionally rare, making his recruitment a significant coup for the firm and a potential differentiator against competitors like FTI Consulting, Ankura, and Kroll, which also vie for top talent in the expert services space.

"As our clients face increasingly sophisticated technologies and equally complex disputes, Dan's combination of technical excellence and analytical discipline is exactly what our practice needs," commented James E. Malackowski, who serves as Ocean Tomo Co-founder and J.S. Held's Chief Intellectual Property Officer. "We are thrilled to welcome him to the team."

Sleeter's career has placed him at the heart of American technological leadership, with roles at the nation's largest military shipbuilder, Huntington Ingalls Industries, and major defense contractors Alion Science and Technology and L-3 Communications (now L3Harris). This foundation, combined with his commercial sector work, provides the holistic perspective needed to advise clients on everything from patent infringement analysis to the valuation of entire technology portfolios.

By bringing this caliber of expertise in-house, J.S. Held is betting that the key to winning the intellectual property battles of tomorrow lies in having the deepest possible understanding of the technology today. As wireless systems continue their march into every corner of modern life, the insights of experts who have operated at the highest levels of technological security and innovation will only become more essential.
