The Japanese IP High Court has reversed the Japanese Patent Office's invalidation of the broad claims in a Universal Display (OLED) patent. The JPO will now take a second look at the matter. (PR)
Universal asserts the patent in question is one of 60+ covering "four early fundamental phosphorescent OLED inventions." The high court's ruling comes two weeks after Universal announced the EPO had affirmed "the basic inventions and broad patent coverage" of a patent being challenged by Sumitomo, Merck, and BASF, albeit while narrowing the scope of the original claims.
