The Stryker is based on the Canadian LAV III light-armored vehicle, which in turn is based on the Mowag Piranha.
Stryker is named in honor of two American servicemen who were killed in action at different times: Pfc Stuart S. Stryker, who received the Medal of Honor for his actions during World War II and Spc Robert F. Stryker, who received the award for his actions during the Vietnam War.
Stryker units seem to be especially effective in urban areas, where vehicles can establish initial security positions near a building and dismount squads on a doorstep.
Stryker disputes this construction and insists that the structure is fully disclosed in the functional limitations of the claim.
Stryker pointed to several references to the spike without reference to the rib limitation and noted that the spike with a rib is denoted as "one unit built according to the invention." See id.
Stryker presented photographs of the accused devices, claim charts, and expert testimony showing that each element of claims 8, 11, and 13 of the 402 patent was present in the accused devices.
