Lenovo has agreed to purchase a portfolio of 21 patent families from Unwired Planet (UPIP). UPIP describes the portfolio as comprising 104 patents and 38 applications that are not currently involved in litigation. It reportedly includes patents related to 3G and LTE mobile technology, and according to a UPIP executive, most of the patents sold to Lenovo derive from UPIP’s January 2013 deal with Ericsson. UPIP says the 142 patent assets make up approximately five percent of the entity’s US and international patent assets and about a third of its standard essential patent assets. The entity maintains that it will own approximately 2,500 patents following the Lenovo transaction.
