eHierarchy, LLC

I'll research this company before writing the profile.

Let me gather a bit more on the entity's ownership and patent portfolio.

eHierarchy, LLC is a Texas limited liability company with a listed place of business at 1400 Preston Road, Suite 400, Plano, Texas. It is privately held; no public ticker, parent, revenue, or employee figures are available in public sources, and its 2020 corporate disclosure in the Tumblr case stated "no corporate parent." Court filings in the QNAP matter identified eHierarchy LLC, inventor Bruce L. Horn, and Endpoint IP LLC as interested parties, indicating the entity is tied to a patent-monetization arrangement rather than to operating assets.

Operations. eHierarchy has no disclosed products, services, or manufacturing. It is a patent-holding/assertion entity that acquires and litigates patents; Stanford's NPE Litigation Database classifies its assertions as based on "acquired patents." Its asserted portfolio centers on U.S. Patent Nos. 8,280,932 and 8,280,945 ("Computer System For Automatic Organization, Indexing and Viewing of Information From Multiple Sources") plus related '063 and '619 patents, covering hierarchical data organization and "sticky path" scrolling displays in user interfaces. RPX noted the patents issued to a named inventor who appears to have been a one-time Microsoft employee.

Litigation posture. In our tracked data eHierarchy appears as plaintiff in one case and as defendant in none — the classic NPE signature: no counterclaims against it, no defensive docket. The tracked suit is eHierarchy, LLC v. Microsoft Corporation (2:16-cv-00564), filed May 25, 2016 in the U.S. District Court for the Eastern District of Texas, Marshall Division (Judge Rodney Gilstrap), asserting four patents against Surface Pro 4, Surface Book, Surface 3, and Windows Phone devices; the case closed June 29, 2016, after roughly 36 days.

Additional public context. Beyond the tracked case, public dockets and databases show eHierarchy asserting the same family against BlackBerry (E.D. Tex., 2:17-cv-00225, 2017), QNAP (C.D. Cal., 2:19-cv-01264, 2019), Tumblr and Verizon Media (S.D.N.Y., 2020; Verizon Media settled in July 2020). The filings cluster in the plaintiff-friendly Eastern District of Texas and target consumer-electronics, mobile, and software defendants. Counsel Richard C. Weinblatt of Stamoulis & Weinblatt appears repeatedly for eHierarchy.
