The Week Ending June 24

Topping this week's roundup of companies and others that had a rough week is Arista Networks, which lost the latest round in its patent legal battle with Cisco.

Also making the list were MobileIron and Arrow Electronics, which terminated with little explanation their highly touted distribution agreement after just four months; HP, for having to recall thousands of notebook batteries because of a fire hazard; privacy advocates, for a judge's ruling in an FBI computer search and data seizure case; and Microsoft, whose Surface Book laptop might not be selling so well.
