Whitewater West Industries, Inc. has brought suit in the District of Oregon against International Play Company, Inc. ("Iplayco")  Both Whitewater and Iplayco are Canadian companies located in British Columbia, Canada.

According to the Amended Complaint (pdf), Whitewater is seeking to enforce three patents directed to enclosed play area structures with multiple levels, sections, and areas, along with cannons and other projectile launchers and projectiles made of impact safe foam or plastic balls. The patents are US6,264,202 (pdf); US5,853,332 (pdf); and US6,283,871 (pdf).

Needless to say, the in-court exhibits for this case should be entertaining.
