The operating system for the AI-native IP law firm.
phronērgon gives small IP teams the firepower and capacity of a big law firm. Built by IP attorneys and AI engineers, it brings AI into every aspect of legal work - for faster, better results and without compromising security.
“In the age of AI, legal IP matters become data science projects.”
Traditional law firm IT was not built for AI.
... and traditional law firms are not ready for what AI can do.
Wasted hours at the cost of the client
Junior attorneys spend hours searching, checking and formatting - work that AI does faster and better. And the client pays for every one of those hours.
Reluctance at the top
The generation in charge hits the brake on AI adoption instead of embracing it - while the firms that move first pull ahead.
IT not ready for agents
The systems a firm runs on were built for people clicking through screens, not for AI agents. Without the right foundation, even the best model cannot do real work.
Tools that do not fit in
Bought solutions, often used via an online platform, sit next to the firm instead of inside it. They do not integrate with the established docketing system or the client's infrastructure.
Knowledge that stays individual
Few know how to use AI efficiently. Everyone does their own thing, and what works for one attorney never becomes knowledge the whole firm can build on.
Vendor lock-in
Bought-in solutions often tie the firm to one vendor - its models, its roadmap and its prices. Switching means starting over.
The back office left behind
Bought-in solutions focus on attorney work. The work of assistants and paralegals - docketing, deadlines, billing - stays as manual as ever.
phronērgon OS: a legal supercomputer for a new era of law practice.
One AI-centric system for the entire firm, in four parts:
- 1Compliant AI sandboxFrontier AI harnesses and models, used safely on client work.
- 2Self-improving infrastructureAgentic AI work that gets better with every case.
- 3Autonomous attorney workAttorney work at unprecedented speed - scalable like software.
- 4AI-native back officeDocketing and billing, built for AI agents from the start.
Compliant AI sandbox
The best AI of the day. Inside a frame you can trust.
phronērgon OS provides a compliant sandbox for frontier AI harnesses and models, such as Claude by Anthropic and Codex by OpenAI - and it also works with self-hosted models.
The system is harness- and model-agnostic: every better model flows into it on day one. Your firm always works with the newest harnesses and models, without waiting for a vendor's next release.
Self-improving infrastructure
A firm that gets better with every case.
In most firms, what works stays with the individual. phronērgon OS turns it into collective knowledge:
Corrections become rules.
When an attorney corrects the system, the correction becomes a rule it applies to every later case.
Client knowledge stays with the client.
What the system learns about a client's technology stays with that client.
Method knowledge grows across all cases.
The rules for patent work draw on all cases - more than any single case could teach.
Autonomous attorney work
Scale the caseload, not the headcount.
In a conventional firm, more work means more people. phronērgon OS breaks that link: autonomous systems carry out attorney work at unprecedented speed and take on a growing share of every case. The caseload grows - the team does not have to grow with it.
AI-native back office
A back office built for AI agents.
Docketing, billing and the rest of the back office are part of the operating system - designed from the start for AI agents. AI takes on the routine work, so the whole team can focus on what matters most to the client.
Built for the firms that lead, not for the average.
Made for high-end IP work
We focus on high-quality IP work by tech-minded people, not on the average law firm.
Agile by design
We react to the newest AI breakthroughs and trends, and your firm always profits from the newest harnesses and models.
No vendor lock-in
Skills and law firm knowledge can be extracted and transferred at any time.
Tailored to you
phronērgon OS is not an off-the-shelf platform. It is tailored to your practice and integrates with your docketing system and your clients' infrastructure.
Grows with you
Start with what you need today and add capacity as your caseload grows - without switching systems or rebuilding your processes.
Full cost control
You always know exactly how much has been spent - and you stay in control of it. No surprises on the invoice.
Your own data space
Client data stays in its own data space and trains no model. AI runs through a compliant enterprise API, and files, data and configuration go with the client at any time.
Built by elite attorneys and AI engineers.
