Best Lock Corp v. Ilco Unican Corp, which blanks in Q?

[WOT]

Ilco (formerly Ilco Unican) was sued by Best for alleged violation of their patent when they distributed generic replacement for Best blanks.

Federal Circuit Court decided in Aug 1996 that Best's patents for their keys had no grounds for valid patent.

Anyone know which blanks this case was about? Their standard A through R blanks, the premium line or everything?

i've never seen an ilco blank for anything but A-R, but the article mentions they were contesting the patents on 34 key blanks, so it sounds like they were going after everything.
