Hi Will L The Nature article was interesting because it has the potential of changing the substrate of choice. Even if it can't be doped to be conducting it may be able to be easily separated from the grown GaN. Also the "type" of GaN grown may be more efficient. All that would have repercussions on the companies hitching their wagons to the white LED. Nakamura thinks that Nichia's position is well protected (as well he might <g>) but I recall that process patents are tough to enforce. I don't know the specifics of the suit, however. Do you have any of the nitty gritty <g>? JF

Can you read this? toyoda-gosei.com I can read only the number 2748818. However, based on the August 31 date of the press release (the date of the decision in Tokyo District Court) and the fact that this is also the number of one of Nichia's Japanese patents, I would guess that Nichia's infringement suit against Toyoda Gosei relied on this patent: JP6338632 Gallium nitride compound semiconductor light-emitting element l2.espacenet.com {Equivalent: JP2748818B2} Only the abstract is in English; drawings are viewable. Not much to go on. This patent has one of the earliest filing dates (May 31, 1993) of Nichia's GaN LED patents. Or, maybe it's just a coincidence. <g> WT
