Rippling Countersues Runlayer Over AI Gateway Patents
On Monday, Rippling filed a patent-infringement complaint against AI security startup Runlayer after Runlayer sued Rippling in July for alleged trade-secret theft. The New York Post reports that Rippling's Delaware complaint alleges Runlayer copied patented software technologies in its AI-agent governance product, while Runlayer characterizes the action as retaliatory. Neither side's allegations have been adjudicated.
Rippling has filed a patent-infringement complaint against New York AI security startup Runlayer, escalating a dispute that began with Runlayer's July lawsuit accusing the HR software company of using confidential information to build a competing AI-agent governance product.
The New York Post reports that Rippling filed its complaint in the US District Court for Delaware. Rippling alleges that Runlayer's platform infringes its patents, misuses its intellectual property, and caused lost sales, lost customers, and price erosion. Those are allegations in a civil complaint, not judicial findings.
A Rippling spokesperson told the Post: "It takes a certain boldness to accuse a competitor of violating intellectual property laws while infringing on that competitor's inventions. But that's exactly what Runlayer has done here."
Runlayer's original allegations
Runlayer sued Rippling in Manhattan federal court on July 28, alleging trade-secret misappropriation, unfair competition, and breach of contract. Reuters reported that Runlayer accused Rippling of misusing its trade secrets after licensing Runlayer software and conducting a product evaluation.
According to Reuters, Runlayer suspended service in June after the companies did not reach a long-term agreement. The complaint cited a message from an alleged Rippling insider stating there was an internal project to build "essentially a clone" of Runlayer that was "almost a 1 to 1 copy."
Runlayer asked the court to block alleged misuse of its trade secrets and sale of a competing product, and sought unspecified monetary damages, Reuters reported. Rippling denied the accusations. In a statement reported by Reuters, a Rippling spokesperson called Runlayer's claims fabricated and said Rippling was launching a product for connecting AI tools to business data using proprietary information.
TechCrunch reported that Runlayer's complaint describes a nearly year-long engineering collaboration during a prospective customer trial. The startup alleges that, under a mutual non-disclosure agreement and trial agreement, it shared product-roadmap details and source code with Rippling. Those assertions remain contested allegations.
The technology at issue
Runlayer provides a security gateway for the Model Context Protocol, or MCP, according to TechCrunch. MCP is a protocol used to let AI models and agents access external enterprise data and tools. Reuters describes Runlayer's product as software for monitoring and controlling how AI agents access enterprise systems.
That category has practical significance for organizations deploying agentic workflows: a gateway can centralize authentication, tool permissions, policy enforcement, and auditability across model-to-system connections. Public reporting frames the litigation around competing implementations of these controls, rather than a dispute over the MCP standard itself.
For enterprise AI infrastructure vendors, comparable disputes illustrate the sensitivity of evaluation environments. Product trials can require deep technical access to architecture, integrations, roadmaps, and sometimes code. Standard contracts and access controls can define the evidentiary record if a commercial relationship later ends in an intellectual-property dispute.
Parallel claims, no ruling
Runlayer has called Rippling's new complaint a retaliatory effort to divert attention from its original lawsuit, according to the New York Post. Rippling's complaint advances the opposite account, alleging that Runlayer copied Rippling inventions. Neither suit's allegations have been adjudicated.
The cases add another legal conflict involving Rippling, which Reuters noted is also engaged in litigation with HR software rival Deel over separate trade-secret allegations. For AI practitioners, the immediate relevance is less about the merits of either side's claims, which courts have not decided, than about the contractual and technical governance of enterprise agent evaluations.
Key Points
- 1Rippling's Delaware patent complaint counters Runlayer's July trade-secret suit, placing competing intellectual-property allegations around AI-agent governance before federal courts.
- 2The dispute centers on MCP gateway functionality, where enterprise controls can govern agent access to data, tools, permissions, and audit records.
- 3Comparable enterprise AI trials often expose sensitive technical materials, making contractual restrictions and access documentation important if commercial negotiations fail.
Scoring Rationale
The litigation concerns MCP-based AI-agent security infrastructure, a growing operational layer for enterprise agent deployments. It does not change the technology itself, but it offers a notable case study in intellectual-property and evaluation-risk management for AI infrastructure teams.
