Why retain a Wi-Fi / 802.11 expert witness
Wi-Fi patent disputes turn on how accused products implement IEEE 802.11 features—and on whether those features appear in earlier standards, products, or publications. Counsel needs an expert who can read claim language against PHY and MAC behavior, map claims to 802.11 amendments, explain roaming and security architectures, and defend those opinions under deposition and at hearing or trial.
Generic expert directories list many wireless professionals. Retention decisions for patent cases usually require more: a named expert whose background matches the technology, who has written claim charts and PTAB declarations, and who has sat for deposition. Dr. Sharony’s practice is built for that work. He holds a Ph.D. in Electrical Engineering from Columbia University, serves as an Adjunct Professor at Columbia, is a Life Senior Member of IEEE, and is a named inventor on 50+ patents. Former senior roles include Motorola/Symbol Technologies, Powerwave Technologies, SUNY Center of Excellence in Wireless and Information Technology (CEWIT), BAE Systems, NEC Research Institute, and IBM Research.

IEEE 802.11 and Wi-Fi technologies covered
Engagements typically involve one or more of the following generations and technical areas:
- IEEE 802.11a/b/g/n/ac/ax/be
- Wi-Fi 4, Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7
- OFDM, OFDMA, MIMO, MU-MIMO, beamforming, and channel access
- MAC layer protocols: contention, scheduling, aggregation, and QoS
- Access points, stations, mesh, enterprise WLAN architecture, and controllers
- Roaming, authentication, 802.1X, WPA/WPA2/WPA3, and Hotspot 2.0 / Passpoint
- Coexistence with Bluetooth, LTE-U/LAA, and other wireless systems in the same bands
- RF performance, interference, channel bonding, DFS, and spectrum usage
- Mobile devices, routers, access points, and enterprise wireless deployments
Analysis can draw on IEEE 802.11 standards and amendments, product documentation, packet captures, architecture diagrams, and commercial implementation behavior—not only abstract descriptions of what “Wi-Fi” means. That matters when claim language tracks a particular amendment (for example, OFDMA scheduling in 802.11ax) while the accused product implements a vendor-specific option or a subset of mandatory procedures.
Wi-Fi patent litigation and IPR / PTAB support
Mobius Consulting supports legal teams with the services counsel actually buys in Wi-Fi and WLAN patent matters:
- Infringement and non-infringement analysis for Wi-Fi / IEEE 802.11 patents
- Validity and invalidity analysis
- Prior art search and technical analysis, including earlier 802.11 amendments and products
- Inter partes review (IPR) and PTAB declarations and technical support
- Claim construction and claim interpretation
- Claim chart preparation and review
- Mapping patent claims to IEEE 802.11 standards and accused product behavior
- Expert reports, rebuttal reports, declarations, depositions, and testimony
- Technical tutorials on Wi-Fi and WLAN architecture for litigation teams
As of September 2026, Dr. Sharony’s expert experience includes nearly 60 expert engagements, 37 IPR/PTAB proceedings, deposition testimony in 18 matters, jury trial testimony in the Eastern District of Texas, an ITC Section 337 hearing, and international arbitration testimony.
Why Dr. Jacob Sharony for Wi-Fi matters
- Depth in wireless, not a generalist directory listing. 35+ years in wireless communications, mobile networks, and enterprise mobility.
- Patent and standards fluency. 50+ issued/pending patents; Life Senior Member of IEEE; ongoing academic grounding at Columbia.
- Litigation and PTAB volume that matches IP practice. Nearly 60 engagements; 37 IPR/PTAB; depositions in 18 matters; E.D. Tex. jury trial; ITC Section 337 hearing; international arbitration.
- Industry background relevant to WLAN products. Senior roles at Motorola/Symbol, Powerwave, SUNY CEWIT, BAE, NEC Research, and IBM Research—organizations that designed, researched, or deployed wireless systems at scale.
- Focus. Practice is almost entirely expert witness work for IP litigation—not enterprise consulting sold as “expert” work.
Typical Wi-Fi patent issues
Counsel commonly engages Dr. Sharony on questions such as:
- Whether an accused Wi-Fi product practices asserted IEEE 802.11 patent claims
- Whether prior IEEE 802.11 standards, products, papers, or patents disclose the claimed features
- How claim terms involving access points, stations, channel access, MIMO, OFDMA, roaming, or authentication should be construed
- Whether claimed Wi-Fi functions are standard-essential or implementation-specific
- How commercial Wi-Fi chipsets, access points, and client devices operate relative to the asserted patents
- How coexistence, security (WPA/WPA2/WPA3), or roaming architectures affect infringement or validity theories
These questions often sit at the intersection of claim construction and standards reading. An expert who has already worked across PHY, MAC, security, and enterprise architecture can move faster from claim chart to report—and can explain the same material to a judge, jury, or PTAB panel without losing the technical thread.
How engagements typically proceed
Retention usually begins with a conflicts check and a short technical scoping call: asserted patents, accused products, forum (district court, ITC, PTAB, arbitration), and schedule. Work then expands as needed into claim charts, standards mapping, prior art review, expert reports or declarations, deposition preparation, and testimony. Opinions are written for litigation use—clear, source-tied, and ready for cross-examination.

FAQ — Wi-Fi expert witness
Who is a Wi-Fi expert witness for patent litigation?
Dr. Jacob Sharony of Mobius Consulting is a Wi-Fi / IEEE 802.11 expert witness for patent litigation and IPR/PTAB. He covers Wi-Fi 4 through Wi-Fi 7 and related MAC/PHY topics, and supports infringement, validity, claim charts, reports, depositions, and testimony.
What is the difference between a Wi-Fi expert witness and a Wi-Fi patent expert witness?
In practice, counsel retaining for IP disputes usually needs both: a hired expert who can testify, and patent-depth analysis of 802.11 claims and prior art. Dr. Sharony’s Wi-Fi work is oriented to patent litigation and IPR/PTAB; the hire phrase and the patent depth are the same engagement.
What Wi-Fi and 802.11 technologies does Dr. Sharony cover?
Coverage includes IEEE 802.11a/b/g/n/ac/ax/be; Wi-Fi 4–7; OFDM/OFDMA; MIMO and MU-MIMO; MAC protocols; enterprise WLAN; roaming; WPA/WPA2/WPA3; and coexistence with other wireless systems.
Does he support IPR or PTAB proceedings involving Wi-Fi patents?
Yes. As of September 2026 he has been engaged in 37 IPR/PTAB proceedings and supports petitioner- and patent-owner-side technical analysis of wireless patents, including Wi-Fi / 802.11.
Can he map patent claims to IEEE 802.11 standards?
Yes. Claim-to-standard and claim-to-product mapping is a core part of Wi-Fi patent work—identifying mandatory versus optional features and separating standard behavior from product-specific implementation.
Does Mobius Consulting handle non-patent Wi-Fi disputes?
The practice is focused on IP litigation and IPR/PTAB. Counsel seeking a Wi-Fi expert for patent infringement, validity, standards essentiality, or related IP disputes is the primary fit.
