The code behind the mobile operating system, WebOS, is being released to open source software developers by Hewlett Packard.
The tech company acquired the software when it bought the smartphone maker Palm for $1.2bn (£767m) last year.
HP used the code to power its short-lived range Touchpad tablet computers before it abandoned the product line.
The firm said it would continue investing in the project to help third parties add enhancements.
“By contributing this innovation, HP unleashes the creativity of the open source community to advance a new generation of applications and devices,” said the firm’s president and chief executive, Meg Whitman.
A statement from the company said it would make the underlying code behind WebOS available under an open source licence. It said third-party developers, partners and HP’s own engineers could then “deliver ongoing enhancements and new versions into the marketplace”.
The firm added that it intended to be “an active participant and investor in the project”.
