IBM tops the list of companies donating patents to a group that aims to help businesses produce greener products by sharing eco-friendly technology. Big Blue has promised 27 patents to the Eco-patent Commons; Nokia, Sony and mail equipment maker Pitney-Bowes will also donate, reports PC World. Shared patents will be freely available to all companies.
The environmentally-friendly technologies covered in the patents already promised to the organization include some for waste water treatment, air purification, cell-phone recycling, and printer ink consumption reduction. The project, inspired by the open-source software movement, intends to help companies tackle environmental challenges that other businesses have already addressed.
