やり直し実地検証と果てし無い特許係争

抄録

In the course of law suits for its possible infringement on GE's patents, another inspection was taken at Komatsu's Hiratsuka plant in March 1967 and proved this time that theyapparatus in question were capable of producing diamond. GE's cause was rejected in 1975 by the Tokyo District court; the 15 years of litigation came to an end when the High Court, after five more years of examination, rejected GE's appeal in 1980 and the latter decided not to appeal to the Supreme Court.
