GPS Expert Witness
We provide GPS and GIS expert witness testimony for litigation involving geospatial information systems, location-based services, satellite navigation, and positioning technologies. Location technology disputes frequently involve patent claims over positioning algorithms, geofencing methods, spatial data processing, or integration of GPS with wireless networks. We analyze system architectures, signal processing implementations, location data pipelines, and standards compliance to deliver defensible opinions on infringement, trade secret misappropriation, and breach of contract claims.
Common Disputes We Handle
GPS and Location Patent Disputes Infringement and invalidity analysis for patents covering satellite positioning methods, assisted GPS, indoor localization, geofencing, and location-aware applications. Source code review, claim chart preparation, and expert reports for district court and PTAB proceedings.
GIS Platform and Licensing Disputes Analysis of geospatial platform functionality, spatial database licensing, mapping API behavior, and data usage rights for breach of contract and warranty claims.
Location Technology Trade Secrets Evaluation of proprietary positioning algorithms, sensor fusion techniques, spatial data models, and mapping system architectures to assess misappropriation or independent development.
Geospatial Data and Privacy Technical analysis of location tracking systems, geolocation data collection practices, consent mechanisms, and compliance with location privacy standards for class actions and regulatory matters.
Representative Engagements
- GPS Patent Infringement Retained in a pre-litigation engagement where a patent portfolio holder identified a top-tier technology company using its patented GPS-related technology. Assisted in identifying potential causes of action, drafting claim charts, and preparing the complaint.
- Geofencing System Trade Secret Misappropriation Retained to analyze source code and development artifacts in a trade secret matter involving a proprietary geofencing and location-triggered notification platform. Evaluated code lineage and assessed claims of independent development.
- Fleet Tracking System, Breach of Contract Evaluated the software development deliverables and system performance for a GPS-based fleet tracking and route optimization platform, assessing whether the delivered system met contractual specifications for location accuracy and real-time reporting.
