4. Oracle
Oracle entered 2012 in full squabble mode with HP over apps for HP's Itanium-based server platform, and eventually lost when a court ruled that Oracle is legally obligated to continue developing software for it.
Oracle also got more aggressive with rival IBM in advertisements promoting its Exadata Database Machines. A little too aggressive, as it turned out. IBM challenged the Oracle ads in a complaint filed July 5 with the Advertising Self-Regulatory Council (ASRC) of the National Advertising Division (NAD). The group ruled in IBM's favor, and Oracle discontinued the campaign.
