Nintendo’s Wii gaming system is again the subject of patent infringement lawsuit. IA Labs, LLC recently filed a Complaint in the District of Maryland against Nintendo alleging infringement of U.S. Patent Nos. 7,121,982 and 7,331,226. Nintendo’s allegedly infringing activities and products relate to the “Wii console video game machines and related ‘Wii Fit’, Wii Fit Plus’, Wii Balance Board’, ‘Wii Remote’, Wii Nunchuck’, ‘Wii Motion Plus’, ‘Wii Zaper’ peripheral devices and software.”
On their face, both patents are assigned to Powergrid Fitness Inc. According to the Complaint, IA Labs acquired the patents from Interaction Labs, which is “also known as Powergrid Fitness.” The ‘982 patent recites two independent claims (claims 1 and 9). Claim 1 recites:
1. An isometric exercise system serving as a peripheral to manipulate a virtual reality scenario of a host processing system in accordance with user exercise, comprising:
a frame to support a user;
an effector to provide an isometric exercise for said user, wherein said effector is fixedly secured to said frame and includes an elongated rod;
at least one sensor coupled to said rod and responsive to at least one force applied by said user to said effector to perform said isometric exercise, wherein said applied force effects a measurable deformation of said rod that is measured by said at least
one sensor; and
a processor coupled to said at least one sensor and including a data processing module to receive and process data corresponding to applied force information measured by said at least one sensor and to transfer information to said host processing system to control said virtual reality scenario of said host processing system in accordance with performance of said isometric exercise and manipulation of said effector by said user.
1. A force measurement system comprising:
an effector device including a hollow interior;
an inner support disposed within said hollow interior of
said effector device; and
at least one sensor secured at a selected location to said inner support and configured to measure a force applied to said inner support; wherein at least one outer surface portion of said inner support is coupled with at least one interior surface portion of said effector device such that forces applied to said effector device are at least partially transferred to said inner support for measurement by said at least one sensor.
