IBM Springs Patent Surprise on Zillow—and Judge Zilly
After 10 months of complex patent litigation against Zillow, IBM filed a second suit this week alleging five new patents. U.S. District Judge Thomas Zilly said he was “quite surprised, even a little shocked,” that IBM would do that while the parties are still trying to get a grip on the first case, and suggested that discovery in the first case might have to be put on hold.
