RFID, NFC & RTLS Expert Witness | Patent Litigation

Dr. Jacob Sharony provides RFID expert witness, NFC expert witness, and RTLS expert witness services for patent litigation, ITC Section 337 investigations, and IPR/PTAB matters involving tags and readers, near-field communication, real-time location systems, asset tracking and visibility, barcode and data-capture systems, and wireless sensor networks.

This is one of Dr. Sharony’s deepest areas of personal expertise: eight years in senior R&D and technology strategy roles at Symbol Technologies / Motorola—a pioneer of RFID, barcode scanning, and enterprise mobility—and named inventor on more than ten U.S. patents in RF-based location, tracking, and asset visibility. As of September 2026, his expert experience includes nearly 60 engagements, 37 IPR/PTAB proceedings, deposition testimony in 18 matters, jury trial testimony (E.D. Tex.), an ITC Section 337 hearing, and international arbitration. The practice is almost entirely expert witness work for IP litigation.

RFID expert witness

As an RFID expert witness, Dr. Sharony analyzes passive and active RFID systems—tags, readers, antennas, anti-collision, backscatter, and inventory protocols—against asserted patent claims and prior art. Work commonly includes EPC Gen2 / ISO/IEC 18000-6C UHF systems, HF RFID, reader networks, middleware, and enterprise asset-visibility platforms used in logistics, retail, healthcare, and transportation. He prepares infringement and validity opinions, claim charts, and testimony for district court, ITC, and PTAB forums.

NFC expert witness

As an NFC expert witness, Dr. Sharony addresses near-field communication patents and products under ISO/IEC 14443, ISO/IEC 15693, and NFC Forum specifications, including NDEF, card emulation, peer-to-peer, and reader/writer modes. Engagements may involve smartphones, payment and access credentials, tags, and dual-interface HF devices where NFC behavior must be mapped to claim language and distinguished from broader HF RFID operation.

RTLS expert witness

As an RTLS expert witness, Dr. Sharony evaluates real-time location systems and RF tracking methods—including RSSI, TDOA, AoA, fingerprinting, and hybrid localization—as well as Wi-Fi-based location, BLE beacons, UWB ranging, and GPS-assisted tracking where those technologies appear in asserted patents or accused products. He is a named inventor on multiple location patents and has testified in matters involving asset tracking and logistics platforms.

Typical questions addressed

Does an accused tag, reader, or tracking platform practice the asserted RFID or RTLS claims?
Do earlier RFID standards, products, or publications disclose the claimed features?
How should claim terms involving interrogation, backscatter, tag identification, location estimation, or asset visibility be construed?
Is the accused localization method (RSSI, TDOA, AoA) within the scope of the asserted claims?
How do EPC Gen2 or NFC Forum specifications map to the accused products’ behavior?
