InterDigital develops wireless technologies for mobile devices, networks, and services worldwide. InterDigital has licenses and strategic relationships with many of the world's leading wireless companies. Founded in 1972, InterDigital is listed on NASDAQ and is included in the S&P MidCap 400 index.

InterDigital has about 20,000 U.S. and foreign issued patents and patent applications.The company is a founding member of the Innovation Alliance - a coalition of entrepreneurial companies that claims to seek to improve the quality of patents granted. In 2012 Business Insider put them on their list of the 8 most fearsome patent trolls.[4] They are frequently called patent trolls because instead of innovating and then building products, they file broad patents on basic communications technology and then sue others for independently coming up with the same innovation.[5][6]

Accusations of patent trolling[edit]

InterDigital is said to be involved in patent licensing, rather than a technology licensing. They don't actually go out and let others use their technology in their products, but instead look for products with overlapping capabilities and sue for patent fees. Their basic method of operation is to threaten with import bans because many of their patents are standards essential patents or SEPs.[8] IN many cases the patents they have declared as essential to a standard are either found to not be essential, or not valid.[9]

They have sued numerous companies for alleged SEP patent infringement, including Huawei, LG, Nokia, Samsung, and ZTE, and have most frequently lost the cases when they were taken to court.[10] In late 2013 They were being investigated by China for monopolistic practices because of their attempt to couple US import bans with licenses in other countries.[11]

Bill Merritt, CEO of Interdigital, disputes the claim of patent troll and even the term in general. He asserts that they work they do promotes innovation and is very helpful to the communications industry.[12]
