2 cases as defendant.
Massively Broadband LLC is a Texas limited liability company formed in February 2023 with a principal place of business in Austin, Texas. It is a private entity with no publicly available information on its employee count or revenue. Analysis from patent industry sources characterizes the company as a non-practicing entity (NPE), also known as a patent assertion entity (PAE), meaning it does not produce products or services and its business is focused on licensing and enforcing patents.
The company does not have any operational business, products, or services. Its primary asset is a portfolio of over 20 U.S. patents acquired from inventor Theodore S. Rappaport on December 31, 2024. The patents asserted in its litigation campaign relate to wireless communications technology, and have been grouped by patent analysts into categories including "Intelligent Wireless Broadband Relay Patents," "Smart Antenna Patents," and "Network Monitoring Patents".
Massively Broadband's litigation posture is that of an NPE asserting its acquired patent portfolio. As shown in the provided case list, the company has initiated four lawsuits as a plaintiff and has been named as a defendant only in responsive administrative patent challenges. In June 2025, the company launched its first and only litigation campaign, filing four simultaneous lawsuits against Samsung Electronics Co., Ltd. and its U.S. subsidiary. All four of these district court cases were filed in the U.S. District Court for the Eastern District of Texas, a venue often favored by patent plaintiffs.
The company's notable legal activity is exclusively centered on its litigation against Samsung. Shortly after being sued, Samsung responded by filing a petition for inter partes review (IPR) with the U.S. Patent and Trademark Office's Patent Trial and Appeal Board (PTAB) in October 2025, challenging the validity of at least one of the asserted patents. The patent risk management group Unified Patents has also filed a PTAB challenge against a Massively Broadband patent. These defensive PTAB filings are a common feature of modern patent litigation.
This was a petition for inter partes review challenging US 8,725,700 on grounds of obviousness. The petition was denied by the PTAB on a discretionary basis.
An inter partes review (IPR) filed by Unified Patents challenging the validity of patent 8,224,794. The PTAB did not institute the IPR on procedural grounds.
