RICHMOND, British Columbia (Sept. 14) — SmarTire Systems Inc. has filed a federal lawsuit against Siemens VDO Automotive Corp. and Schrader-Bridgeport International Inc., claiming the companies have infringed on the patent for its tire monitoring system.

According to the patent, the system monitors the condition of tires and transmits measurements of tire temperatures and pressures to an interior receiver.
An attorney for SmarTire said he had no additional comment on the case. Siemens had no immediate comment.
A court clerk said the case has been transferred from the federal court in Richmond, Va., to Alexandria, Va. The plaintiff said the patent at issue is No. 5,231,872.
