Sampo IP LLC

Sampo IP, LLC is a patent assertion entity and a wholly-owned subsidiary of Marathon Patent Group, Inc. (now known as Marathon Digital Holdings, Inc.), a patent acquisition and licensing company. As a subsidiary formed to hold and assert patents, Sampo IP does not have its own employees or revenue in the traditional sense; its business activities are conducted by its parent company. A 2014 SEC filing lists its place of business in Alexandria, Virginia, the same city as its parent.

Sampo IP, LLC is a non-practicing entity (NPE) that does not manufacture products or offer services. Its sole operation is to generate revenue by licensing and enforcing a portfolio of acquired patents. The patents asserted in all its tracked litigation campaigns are U.S. Patent Nos. 6,161,149, 6,772,229, and 8,015,495, all of which are titled "Centrifugal Communication and Collaboration Method." These patents generally relate to communication systems and methods.

Reflecting its business model as a patent assertion entity, Sampo IP has only appeared as a plaintiff in the provided litigation data, with four tracked cases and zero as a defendant. The company filed its lawsuits in 2013 and 2014 in jurisdictions known to be plaintiff-friendly at the time, including the U.S. District Courts for the Eastern District of Texas, the Eastern District of Virginia, and the District of Delaware. This litigation pattern is characteristic of an NPE engaged in a monetization campaign.

The company's litigation campaign targeted a wide range of large technology and service companies. Notable defendants included Facebook, Amazon, LinkedIn, and eBay in a 2014 Delaware lawsuit. Other campaigns filed in 2013 named defendants such as E*Trade, Starbucks, and Hewlett-Packard in the Eastern District of Texas, and Blackboard and Salesforce.com in the Eastern District of Virginia.
