The event, part of Adobe's annual week long MAX developer conference, will focus on product solutions for web browsers and apps, according to the company's website (via The New York Times). The MAX conference is scheduled to run from Oct. 1-5.
Adobe will also hold a keynote, entitled "Creativity unleashed," on Monday. The event will feature Adobe CTO Kevin Lynch as he showcases how the company is "transforming the creative process across mobile devices, personal computers, and the cloud.
Apple rivals BlackBerry (Research in Motion), HP, Motorola, Samsung and Sony are listed as "platinum sponsors" of the conference.
It is not immediately clear which company first chose their respective keynotes, though Apple only sent out invitations for its event on Tuesday of this week. However, Adobe is not expected to make any major product announcements at the event, as it would likely be eclipsed by Apple's news.
For its part, Apple is expected to announce the fifth-generation iPhone next Tuesday. The handset is assumed to feature a faster A5 processor and an improved camera. Recent evidence suggests that the so-called "IPhone 5" could feature virtual personal assistant voice control functionality.
The Cupertino, Calif., company will also likely highlight its iOS 5 and iCloud software on Tuesday ahead of their release this fall.
Apple's Oct. 4th iPhone event also conflicts with Oracle's OpenWorld conference. That event runs from Oct. 2-6 at the Moscone Center in San Francisco and will attract tens of thousands of attendees.
Adobe and Apple exchanged tense words in 2010 over the issue of Flash on iOS devices. Apple's then CEO Steve Jobs said in an open letter that his company shared "few joint interests" with Adobe and had "grown apart." Adobe CEO Shantanu Narayen called Jobs' letter a "smokescreen."
In recent months, the two companies' relationship appears to have improved. Earlier this month, Adobe announced support for Apple's Newsstand application, new to iOS 5, in its Digital Publishing Suite. Users will now be able to create Newsstand-compatible digital publications for iOS devices. The company also recently added HTML5 video support for iOS devices in its Flash Media Server product.
