Yesterday an unidentified party requested reexamination of U.S. Patent No. 5,825,427, a patent of some commercial significance for motion-sensitive sound effects devices in projectors. The ‘427 patent is owned by Ogma, LLC, located in Longview, Texas.
In March Ogma sued 3M, Canon and 26 other projector-makers in Marshall, Texas, accusing them of infringing the ‘427 patent. Ogma also filed a complaint with the U.S. International Trade Commission on the basis of the ‘427 and a related patent, U.S. Patent No. 6,150,947. The ITC instituted an investigation in May. Ogma filed a second ITC complaint, which will likely be merged with the pending investigation.
