On its blog, Google has invited patent holders to sell their patents through its experimental portal.
Patent holders will be able describe their patents and tell their desired selling price to Google with its Patent Purchase Program.
The program will be open to participation from May 8 through May 22, 2015. After this deadline the firm will review the submissions and tell the submitters if it is interested in buying the patents by June 26. And if Google decides to buy, it anticipates the transaction will be completed by late August.
