Networking Software Expert Witness
We provide computer networking expert witness testimony for litigation involving network architectures, routing protocols, switching systems, and network security. Networking disputes frequently center on protocol implementations, network performance, infrastructure design, or standards compliance. We analyze source code, packet captures, network configurations, and system logs to provide defensible opinions on infringement, trade secret misappropriation, and breach of contract claims.
Common Disputes We Handle
Network Protocol Patent Disputes Infringement and invalidity analysis for patents covering routing algorithms, switching architectures, packet processing, and protocol stack implementations. Source code review, claim chart preparation, and expert reports for district court and PTAB proceedings.
Network Infrastructure Contract Disputes Analysis of network system functionality, performance benchmarks, service-level compliance, and configuration standards for breach of contract and warranty claims.
Networking Trade Secrets Evaluation of proprietary network architectures, protocol implementations, firmware, and source code lineage to assess misappropriation or independent development.
Wireless Network Disputes Technical analysis of WiFi, cellular, and IoT networking systems, including RF performance, spectrum management, handoff mechanisms, and standards-essential patent claims.
Representative Engagements
Base Station Source Code Patent Infringement Analyzed base station source code for multiple potential infringers against established claim charts. Identified and documented potentially infringing behavior with source code citations and helped draft expert declarations.
Patent Portfolio Evaluation Analyzed and categorized a newly acquired patent portfolio for a large communications equipment manufacturer. Organized patents into technology sub-areas and families, identified assertion targets, and created initial claim charts for selected families against a specific target.
DMCA and Contributory Copyright Infringement Retained by the two largest U.S. bridalwear companies in a contributory copyright infringement matter against a cloud firewall provider. Provided technical interpretation of networking terminology central to the DMCA safe harbor analysis.
