6018041

Hyseq filed a patent infringement complaint against Affymetrix in the Northern District of California on March 4, 1997, asserting Hyseq's sequencing-by-hybridization patents in the Drmanac/Crkvenjakov family. The dispute was settled in October 2001; the narrative states that assertion of US 6,018,041 specifically was not confirmed.

Affymetrix brought an action against Hyseq and Incyte in the Northern District of California asserting Affymetrix's own array patents ('934, '305, '992, and '716). The 2001 decision at 132 F. Supp. 2d 1212 is a Markman claim-construction ruling and did not address US 6,018,041.
