Location Based Services Expert Witnesses

Start Location Based Services Expert Search

Location Based Services (LBS) expert witness candidates typically possess backgrounds in software engineering, network communications, and/or have specialized knowledge in GPS or GIS. Location based services use real-time geo-data from a cell phone (or other mobile device) to disseminate information. Location based services use GPS technology to track a device location. Some examples of how businesses and consumers utilize location-based services include:

• Turn-by-turn navigation
• Locating friends/family on a map displayed on a mobile phone
• Location-based mobile device advertising
• Sending a cell phone location during an emergency call
• Recommending events (such as via Yelp)

• Using location-based intelligence, helping retail customers to find a nearby store
• Geo-fencing, which is a virtual perimeter (for example, notifying parents if a child penetrates a certain zone, or sending an alert if a vehicle is stolen)
• Travel information (traffic updates, road conditions and weather reports)
• Fraud prevention (syncing a customer’s location to a credit card transaction)
• Managing a mobile workforce by tracking employees in the field (delivery services, repair services)

Often, matters requiring location-based services expert witness work involve patent infringement litigation. Expert witness services by a location-based services expert witness could include an expert report, expert opinion, and/or trial testimony. In a high-profile case, or litigation involving a significant financial stake, an attorney may require a testifying expert with prior expert witness testimony experience. In addition, clients often seek an industry expert for pre-litigation consulting work.

While many experts have location-based services expertise, an expert witness carries the additional responsibility of providing testimony before the court in a manner whereby lay people can understand the technology and evidence.
