Typical questions addressed

Does an accused product’s Bluetooth pairing, advertising, or data exchange practice the asserted claims?
Do earlier Bluetooth specifications, products, or publications disclose the claimed features?
How should claim terms involving pairing, beacons, advertising packets, profiles, or low-energy operation be construed?
How does an accused device implement BLE beacons, proximity detection, or location features?
How do Bluetooth and Wi-Fi coexist in the accused products, and which standard governs the accused functionality?

How Bluetooth expert witness engagements proceed

Retention typically starts with a conflicts check and a technical scoping call covering asserted patents, accused products (Classic, BLE, beacons, paired accessories, or mesh), forum, and schedule. Work then expands into claim charts, Core Specification and profile mapping, prior art review against Bluetooth SIG materials and earlier products, expert reports or PTAB declarations, deposition preparation, and testimony. Opinions are written for litigation use—tied to specifications and product behavior, and ready for cross-examination.

FAQ — Bluetooth expert witness

What does a Bluetooth expert witness do in patent litigation?

A Bluetooth expert witness analyzes accused products and prior art against asserted Bluetooth or BLE patent claims, prepares claim charts and reports, and may testify at deposition, hearing, or trial. Dr. Sharony focuses on IP litigation and IPR/PTAB for Classic Bluetooth, BLE, beacons, profiles, security, and coexistence.

What Bluetooth technologies does Dr. Sharony cover as an expert witness?

Bluetooth Classic (BR/EDR), Bluetooth Low Energy (BLE), beacons (iBeacon/Eddystone), Bluetooth profiles (including A2DP, HFP, HID), pairing and security, GATT, mesh, and coexistence with Wi-Fi—across smartphones, wearables, audio, medical, automotive, and IoT products.

Has he worked on BLE beacon patent cases?

Yes. Representative matters include BillJCo v. Cisco Systems (E.D. Tex.) and BillJCo v. Apple (W.D. Tex.), which involved BLE beacon technology.

Does he support IPR proceedings involving Bluetooth patents?

Yes. As of September 2026, Dr. Sharony has been engaged in 37 IPR proceedings at the PTAB and supports petitioner- and patent-owner-side analysis of Bluetooth and short-range wireless patents.

Can he analyze accused products at the protocol level?

Yes. Analysis can include protocol traces, sniffer captures, specification mapping, firmware/product documentation review, and testing of accused Bluetooth functionality.
