We were engineers first.

Every attorney here holds a technical degree and shipped real work before law school, compilers, silicon, medical devices. It means we don't need your CTO to translate. We read the spec, understand the invention, and write claims that map to how the technology actually works.

We stay small so a partner drafts your applications, not a first-year you never meet. Fixed fees on prosecution, and no matter opens without a scope you approved.
