Counsel for the frontier of computation.

Intellectual property strategy for AI, post-quantum cryptography, cybersecurity, and data-driven systems.

A key that can sign exactly once

A one-shot signature is a digital signature whose quantum signing key |sk⟩ is consumed by the measurement that produces the signature, so a second signature under the same public key is information-theoretically unavailable. Classical keys are copyable bitstrings; quantum keys are not, and the act of signing and the act of destroying the key are the same measurement.

01 In brief

Most of what our clients build does not yet have settled law. That's where we work: patent strategy for artificial intelligence, post-quantum cryptography, cybersecurity, and large-scale data systems, and ongoing counsel for companies whose technical decisions define their legal posture.

Built on three commitments that shape every engagement.

I
Technical literacy

We read the papers. We run the code.

We understand the underlying technology with the rigor of a practitioner, not a generalist.

II
Institutional rigor

Every deliverable is built for diligence.

The patent drafted today is the exhibit in a Series B data room tomorrow. We write with that horizon in mind.

III
No handoffs

The team you hire is the team on the work.

Your project is not passed down through a staffing pyramid.
