RPX Corporation

What RPX Corporation does

RPX Corporation is a privately held patent risk management company founded in 2008 and headquartered in San Francisco. It pioneered the defensive patent acquisition model, operating a membership-based network of 290+ technology companies. Members pool resources to acquire patents before they become litigation threats, with RPX having spent over $5.5 billion to acquire more than 260,000 patent assets and achieving 2,600+ litigation dismissals. The company monetizes through three primary streams: annual network membership subscriptions (recurring), defensive patent acquisition and licensing transactions (one-time license), and the RPX Empower SaaS platform (subscription), with additional services including insurance and patent sales.

The company's technology backbone is RPX Empower, a proprietary cloud-based patent intelligence platform launched in April 2024, which provides portfolio assessment, litigation intelligence, license management, prior art searches, PTAB analytics, and a SEP Explorer module. The platform is built on what the company describes as the industry's most extensive proprietary database on patents and patent litigation, supporting end-to-end IP strategy workflows. The Patent Quality Initiative complements this with prior art searches (2,820+ launched, 840+ reports published) and validity challenges through inter partes reviews (730+ PTAB petitions citing RPX-identified prior art). Recent strategic integrations with Patlytics and IPRally point to ecosystem buildout.

RPX serves enterprise technology companies facing patent infringement exposure, patent sellers seeking efficient monetization, and IP professionals needing market intelligence. Go-to-market is sales-led with direct enterprise engagement and a self-serve component for RPX Empower. The company maintains global operations with offices in San Francisco, Los Angeles, Tokyo (regional HQ for Asia), and Taipei, and is expanding into Europe with a dedicated VP appointment in March 2026. RPX was previously public on NASDAQ under ticker RPXC before being taken private; no current external ownership or investor composition is disclosed in available materials.

Broad incumbents

• Questel (Orbit Intelligence): Global IP service provider offering Orbit Intelligence for patent search, analytics, and IP management; competes directly with RPX Empower on patent intelligence, watch, and competitive monitoring workflows.
• Anaqua: Leading IP management software platform providing patent portfolio management, annuity payments, and IP analytics to enterprises and law firms — competing with RPX Empower on the IP software side though without the defensive acquisition business.
• Intellectual Ventures: One of the world's largest patent holders and a former patent assertion entity that has shifted toward licensing; RPX landmark deal with IV in 2021 shows direct overlap on the transaction side despite IV's much larger portfolio and broader invention funding heritage.
• Clarivate (formerly CPA Global): Major IP intelligence and patent analytics provider (Derwent, CompuMark, MarkMonitor) with overlapping patent search, prior art, and portfolio assessment capabilities relative to RPX Empower.
• LexisNexis PatentAdvisor: Patent analytics platform from LexisNexis focused on patent examiner behavior, prosecution analytics, and litigation intelligence — overlapping with RPX Empower's PTAB Analytics and Litigation Intelligence modules.

Emerging players

• Patlytics: AI-native patent workflow platform for IP attorneys; announced strategic integration partnership with RPX in 2026, representing a complementary/competing overlay for AI-driven portfolio assessment and prior art workflows that RPX Empower users already access.
• PatSnap: AI-powered patent and innovation intelligence platform competing with RPX Empower on analytics, prior art, and competitive intelligence, with stronger machine-learning positioning for tech-forward IP teams.

Direct peers

• LOT Network: Defensive patent pool providing members with licensing rights if a member's patent is acquired by a patent assertion entity, conceptually parallel to RPX's defensive acquisition network and targeting similar enterprise technology members.
• Allied Security Trust (AST): Bipartisan defensive patent acquisition consortium formed by major tech companies to buy patents outside the courtroom; competes head-to-head with RPX Network on syndicated defensive acquisitions for enterprise technology members.
• Unified Patents: Direct competitor in defensive patent acquisition and patent risk management, operating a membership-based model similar to RPX Network with focus on technology company members and PTAB-based validity challenges.
