Year Retained By Description Deposed? Trial?
2018 Plaintiff Plantiff, who ambulates with a rolling walker, was visiting an automobile dealership in Las Vegas, Nevada. While exiting the premises, one of the rear legs of the walker caught on a doormat inside the premises, significantly buckling the doormat and causing the plaintiff to trip and fall. Provided opinions related to the design of the walker (specifically, the rear glides, which are unnecessarily unsafe), the condition of the doormat (which did not lay flat on the floor), and ADA (in terms of accessible routes). Yes No (case settled)
2018 Plaintiff A Maryland Medicaid wheelchair transportation provider was transporting a passenger to a medical appointment. The driver failed to use the Wheelchair Tiedown and Occupant Restraint System as needed. The passenger fell from the wheelchair during transit, breaking both legs. Provided opinions as to the the applicable ADA regulations and standard of care in transporting passengers seated in wheelchairs and the multiple breaches of the ADA regulations and standard of care by the defendants. Yes No (case settled for $1.5M)
2017 Plaintiff An elderly woman with Multiple Sclerosis was provided a power wheelchair with a joystick and electronics that had design defects. The electronics had 5 programmable "drive" modes, the desired mode selected by engaging a Down button or an Up button. However, the system was designed as a circular loop in that repeated engagement of the Down button moved the wheelchair from drive mode 1, programmed with the slowest and least responsive parameters, directly into drive mode 5, programmed with the fastest and most responsive operational parameters. Further, this could be done while the joystick was being used. While driving the power wheelchair in her home in drive mode 1, the plaintiff inadvertently bumped the Down button on the joystick, causing the wheelchair to rapidly accelerate, propelling the plaintiff and wheelchair into the wall, breaking the plaintiff's leg. Provided opinions related to the system's defective and unsafe design and the defendants' failure to provide any warnings on this safety issue. Of note, other joystick designs are available and used by other wheelchair manufacturers that do not possess this design defect. Yes No, case resolved through arbitration.
2017 Defendant Plaintiff claimed the defendant infringed on a Canadian patent related to a "mobility aiding device." Provided testimony pertaining to the qualifications and common general knowledge of the POSITA, construction of the 18 claims of the patent, rebuttal to the claim of infringement of 2 of the 18 claims, and validity of the 18 claims (anticipation, obviousness, and mere aggregation).   Yes
2016 Defendant Plaintiff using a 3-wheel scooter on a cruise ship got temporarily stuck on an exterior door threshold. Once free, the plaintiff exited the doorway, drove down a ramp, and made a sharp turn, tipping over. Testified to the instability of 3-wheel scooters, made worse by the fact that the plaintiff was a lower extremity amputee, the prevalence of scooter tipover accidents absent getting stuck on a threshold, and the liklihood that the plaintiff would have tipped over without becoming stuck prior to exiting the door. Yes No (case settled)
2015 Defendant Plaintiff in a skilled nursing facility was using an electronic bed for 2.5 years when a part of the bed broke. The skilled nursing facility continued to use the bed while waiting for replacement parts. The plaintiff fell from the bed breaking her leg, which contributed to her death. Testified to the design of the bed, the functionality of the bed prior to, and after, its breakage. Offered opinions, based on testing of an exemplar bed, that proved the fundamental assumptions of the plaintiff's expert were flawed, his opinions on the cause of the incident, which were based upon his assumptions, were erroneous, and that the malfunctioning bed did not contribute to the plaintiff's fall and injuries. Yes No (case settled)
