The companies didn't announce the transaction until yesterday, despite it taking place in the third quarter of 2012.
Apple has acquired 18 patents related to "axis-based user interface technology," the intellectual property's former owner Maya-Systems announced yesterday.
According to Maya-Systems, which developers content-management technologies, the companies signed the deal in the third quarter of 2012. Apple acquired only a portion of the company's axis-based user interface technology.
Maya-Systems' axis-based technologies allows developers to group files around a given axis. In some cases, that can mean timelines. The technology is available in the company's IAmOrganized program, which provides file management and cloud storage.
That cloud-storage element is making some folks across the Web speculate that Apple might be working on cloud-based projects, and will incorporate Maya-Systems' technologies into its online products, like iCloud.
Maya-Systems did not disclose financial details of its deal with Apple.
CNET has contacted Apple for comment on the patent purchases. We will update this story when we have more information.
