Klarquist defended GE and GE Healthcare in a patent infringement suit brought by the University of Washington. Klarquist promptly initiated an inter partes reexamination of the patent in suit, and after only six months of litigation obtained a stay of the case pending reexamination. After office actions rejected all challenged claims in reexamination, the University of Washington dismissed with prejudice its lawsuit. The Patent Office subsequently cancelled all challenged claims in reexamination.
