Window Wars: Magistrate Ryu Strikes Untimely Intervener Invalidity Contentions

Motion to Stay Strike Invalidity Contentions Granted, Sage Electrochromics Inc. v. View Inc., Case No. C 12-06441 (Magistrate Judge Donna Ryu)

Move over, smartphone wars.  The "window wars" are raging right here in the Northern District of California, and a new order from Magistrate Judge Ryu provides a glimpse into the action.  The order is also a useful lesson for intervening parties:  when interveners miss their infringement or invalidity contentions deadlines, they should not expect any special treatment.

Both Plaintiff Sage Electrochromics, Inc. and Defendant View, Inc. sell electrochromic glass, sometimes called "smart glass" or "dynamic glass," that can switch between clear and tinted states.  The technology could potentially save building owners a lot of money on their utility bills.  Both Sage and View have asserted patents against each other.
