Legal Experience & Services
Automated Guided Vehicle Also known as Automatic Guided Vehicles or AGVs, these robotic vehicles are typically used to move materials and products in factories and warehouses. This workplace accident occurred when a robotic forklift moving heavy rolls of paper in a paper press misplaced the paper roll on its receiving stand. The roll fell from the stand and struck the machine operator. In this case I assisted the attorneys with discovery, provided insight into the technical aspects of the system, analyzed the machines control computer, conducted a plant inspection, analyzed the relevant AGV safety standard, wrote two expert reports and testified at deposition.
Automation Networking and Control Software This patent case involved factory automation and computer integrated manufacturing software products. I was retained by Plaintiff and assisted with evaluating issues of validity, infringement and prior-art products cited by Defendants. I met with Plaintiff's damages experts to help them understand the technology and background of the industry. I also conducted a code inspection and analysis of Defendants software source code.
Automobile Manufacturing Assembly Line This accident occurred when an automobile assembly moved unexpectedly and one of the vehicles struck a worked. As an expert witness in this case, I analyzed the ladder logic line control software, identified the defective rung of ladder logic and was able to show when this defect was introduced into the software. In this case I testified at deposition.
Bindery Line Controller This case involved a company that had developed a redundant, fault-tolerant safety controller for a bindery line that they claimed was safer than OSHAs Lockout/Tagout Regulation (Control of Hazardous Energy Standard). In this case the United States Secretary of Labor retained me to analyze the controllers design and evaluate the companys claim relative to the OSHA Lockout/Tagout standard.
Brick Stacking Robot This workplace accident occurred when an industrial robot moved unexpectedly and struck the operator who was clearing a row of improperly stacked bricks. I analyzed the safety systems, modifications to the system subsequent to delivery, the design of the systems controller, compliance with robot safety standards and generally consulted with the attorneys to help them understand the technical aspects of the robotic system. My work included an expert report on the matter.
Computer Controlled Overhead Hoist This industrial accident occurred when a computer-controlled overhead crane moved unexpectedly while an operator was inside an automated manufacturing cell that was grinding and finishing automobile crank shafts. The automated cell was surrounded by a safety barrier fence, but the safety interlock had been defeated to allow the operator in the cell without triggering a shut-down. As an expert witness in this case, I met with the attorneys, examined photos of the accident scene, provided an assessment of the cell design relative to pertinent safety standards and assessed the design of the safety interlocks.
Computer Controlled Press Brake This industrial accident involved a 400-ton press brake controlled by a Programmable Logic Controller, or PLC. I analyzed the machine, the ladder-logic software, the programmable logic controller, the machine safe guarding and conducted a plant inspection to assist the attorney in understanding whether the software or the hardware were defective.
Computer Controlled Vending Machine This patent dispute involved a computer-controlled vending machine. The vending machine employed a robotic mechanism to dispense t product. I was retained by the Defendant and assisted with analysis and issues of validity and infringement. I wrote an expert report in this matter that addressed three patents.

In this case I analyzed the machine guarding, analyzed the machine warnings, analyzed the machine controller and generally assisted the attorney with discovery.
Power Operated, Automatic Pedestrian Door This accident occurred when an automatic pedestrian door closed on a person and knocked her to the ground. Though it is not immediately obvious, an automatic door is an example of a robotic system. It has sensors that control its operation, a motor that supplies power and a mechanism that transfers power from the motor to the doors. In this case I inspected the faulty door, wrote a written report, testified at deposition and testified in front of a jury at trial.
Robotic Suturing Device This patent dispute in the general field of medical robotics specifically involved a robotic surgical suturing instrument. I reviewed the pleadings in the case, the patents at suit, the prior art, the products at suit, assisted the attorneys composing the infringement contentions and assisted the attorneys with their response to the invalidity contentions.

I assisted the attorneys with understanding prior art in the field of teleoperation and alerted them to prior art teleoperated robots developed for use in radioactive environments.
Theater and Stage Automation Though many people are not aware of it, modern theater often has a huge automation content that could involve hundreds of axes of motion. These are controlled by logic controllers very much like the logic controllers used in manufacturing. This accident occurred when an automation operator inadvertently left a trap door open during a pre-show check. An actor was injured when he fell through the open trap door. In this case I assisted the attorneys in understanding the technology, studied the log files from the time of the accident to identify the missed step in the pre-show check and wrote two expert reports. The second was in support of a successful motion for summary judgment.
Tire Making Machine This industrial accident occurred when tire making machine sequenced by a programmable logic controller moved unexpectedly and struck a maintenance technician who was clearing the machine of a jam. In this case I provided engineering expert witness services that included analysis of the machine's control software, identification of the defective ladder logic code, a comparison of the machine involved in the accident with a previous-generation machine that was controlled by a drum sequencer rather than a computer and expert witness testimony at deposition.
Wood Manufacturing Process Control This accident occurred when a thermal process controlled by a Programmable Logic Controller (PLC) got out of control and caused an explosion. I assisted the attorneys in understanding the root cause of the accident and how the PLC and its control software were involved.
