1 case as defendant.
KEMP Technologies, Inc. ("Kemp") was founded in 2000 in Bethpage, New York, and operated in the application delivery controller (ADC) and load-balancing market. Public sources place its headquarters at various points in Melville, NY and New York City; a Limerick, Ireland office served as European headquarters from 2010. It was privately held, backed by Edison Ventures, Kennet Partners and ORIX Venture Finance, then acquired by private equity firm Mill Point Capital in 2019. In November 2021 Progress Software (NASDAQ: PRGS) completed its acquisition of Kemp for $258 million in cash, and Kemp became a Progress subsidiary. At the time of the deal, Kemp was reported to have roughly $70 million in revenue; a standalone public employee count is not well documented.
Products and operations. Kemp was an operating software company, not a patent-assertion entity. Its flagship product was LoadMaster, a Layer 4–7 load balancer / ADC built on its proprietary LMOS Linux-based platform and sold as a hardware appliance, virtual appliance (VMware, Hyper-V, bare metal), and cloud image (Microsoft Azure, AWS), along with a free tier. Additional lines included Kemp 360 Central (centralized monitoring/reporting across multiple ADCs) and Kemp 360 Vision (application health monitoring), plus a geo/GSLB load balancer. Kemp acquired Flowmon Networks in 2020, adding network performance monitoring and network detection/response; Flowmon and LoadMaster were folded into Progress's portfolio.
Litigation posture. The tracked data show Kemp with zero plaintiff cases and one defendant case — the profile of an operating company targeted rather than an active litigant. That sole suit is FireNet Technologies, LLC v. KEMP Technologies Inc., filed June 20, 2018 in the Southern District of New York (Judge Andrew L. Carter, Jr.). FireNet is characterized by Unified Patents as an "IP Investments affiliate and well-known NPE," and the case was part of a broader FireNet campaign against networking vendors including Fortinet, Citrix, A10 Networks and Fujitsu. Kemp answered and filed a Rule 7.1 disclosure stating no corporate parent at that time.
Context. The asserted patents (e.g., U.S. 8,892,600, "Security for a Network Attached Device") cover firewall/proxy network-access control — technology adjacent to Kemp's load-balancing and application-delivery products. Unified Patents later filed an IPR against the '600 patent, which the PTAB instituted in September 2020. No outcome for the Kemp case itself is reflected in the tracked data.
FireNet Technologies, LLC sued KEMP Technologies Inc. in the Southern District of New York. The complaint is confirmed to have asserted the same four-patent family as U.S. Patent 6,317,837, 7,739,302, 8,306,994, and 8,892,600. Final disposition was not confirmed; the case appears in a later IPR record as prior litigation.
