Mirror Worlds, LLC

Mirror Worlds, LLC is a patent-holding entity formed in March 2008 in Tyler, Texas (4540 Kinsey Dr.), and a wholly-owned subsidiary of Plainfield Specialty Holdings I, Inc., a Delaware corporation. It is not the same entity as the original Mirror Worlds Technologies, Inc., the New Haven, Connecticut software company founded by Yale computer scientist David Gelernter (with Eric Freeman) that released the "lifestream" product Scopeware in 2001 and ceased operations in May 2004. Mirror Worlds, LLC files no SEC reports of its own; no employee count, revenue, or market-cap figures are publicly reported. It later sold its patents to Network-1 Security Solutions, Inc. (now Network-1 Technologies, Inc.; NYSE American: NTIP) via Network-1's subsidiary Mirror Worlds Technologies, LLC on May 21, 2013, in exchange for consideration including warrants for 875,000 Network-1 shares.

Operations. Mirror Worlds, LLC has no products or services. A court-filed stipulation of facts in the Apple case states the LLC "never sold or offered to sell the Scopeware products" and had nothing to do with their development. It was created to hold patents acquired from Recognition Interface, LLC (which had bought the assets of the original Mirror Worlds Technologies in June 2004), including U.S. Patent Nos. 6,006,227; 6,638,313; 6,725,427; and 6,768,999, covering a "document stream operating system" for time-stamped document organizing, display, search, and archiving. It is properly characterized as a non-practicing entity / shell licensor asserting an acquired portfolio.

Litigation posture. The case data is consistent with this: one tracked case, as plaintiff, zero as defendant. Mirror Worlds, LLC v. Apple Inc. was filed March 14, 2008, in the U.S. District Court for the Eastern District of Texas, Tyler Division—a plaintiff-favored venue.

Notable case. On October 1, 2010, a Tyler jury found Apple willfully infringed three patents (targeting Apple's Spotlight, Cover Flow, and Time Machine features) and awarded $208.5 million per patent, $625.5 million total. Judge Leonard Davis vacated the verdict in April 2011 for insufficient evidence of infringement and damages; the Federal Circuit affirmed, and the Supreme Court denied certiorari on June 24, 2013. Network-1 later reported roughly $47.15 million in revenue from the portfolio; those patents have since expired.
