During Microsoft's Worldwide Partner Conference last week in Toronto, Canada, Steve Ballmer vowed that they weren't "going to leave any space uncovered to Apple." He later added that "We have our advantages in terms of enterprise management," and then shouted "But we are not going to let any piece of this [go uncontested to Apple]," reported CRN. So why is Microsoft freaking out now? Because Apple is getting a little too close to home base. Back in January Peter Oppenheimer stated that the iPad was continuing "its unprecedented adoption in business. Nearly all the top companies, within major Fortune 500 markets, including pharma, manufacturing, hospitality, consumer products, financial services, healthcare and retail are actively using iPad to improve workflows, business processes and customer engagement." Some of the companies that Oppenheimer pointed out included the likes of Royal Dutch Shell, Credit Suisse, Kimberly-Clark, St. Jude Medical, Nike, Danske Bank and Facebook. Adding to this, John Paczkowski of All ThingsD reported that 95% of the tablets going into the Fortune 500 Companies were iPads. Is it clear enough that Apple is focusing on the Fortune 500 and the enterprise market in general? If it's not, then consider a new round of high profile security patent applications published this past week by the US Patent Office that reveals that Apple is developing new features to work with the already high end Advanced Encryption Standard approved by the US Government. So it's no wonder Mr. Ballmer was freaking out this past week. The one time consumer-centric company called Apple is now on the warpath toward the enterprise at full throttle with iOS leading the charge. So yes Mr. Ballmer, we get it, you just woke up and you're freaking out. So enough with talk, let the war games begin. But for now, we'll take a look at Apple's new security patents.
