Patent your inventions

For too long, protecting an invention has been too expensive, too slow, and too opaque. But for a company whose edge is its technology, a strong patent is what keeps competitors from copying what you built.

Searchlight starts with the technology and the prior art, decides what's actually worth claiming, and drafts applications with examiners, competitors, and courts in mind.

The result: stronger protection at a fixed price, with less founder time lost to legal process—patents built to hold up, not just fill a portfolio.

Defend against assertions

If you're sued for patent infringement, you know that millions or billions of dollars can be on the line. A strong invalidity strategy isn't just nice to have—it's essential.

Searchlight identifies prior art, maps claim limitations, develops candidate combinations, and analyzes priority and prosecution history.

The deliverable is built for counsel who need more than a list of references: they need arguments that can be tested, explained, and used to convince judges and juries.

AI-Native Working Model

AI where it helps. Judgment where it matters.

AI where it helps

Searchlight uses purpose-built AI to make the mechanical parts of patent work faster and broader: searching technical records, comparing claim language, organizing file histories, and drafting from structured analysis.

Judgment where it matters

The judgment stays with a patent attorney who understands the technology and the downstream fight: what to protect, what not to overclaim, which prior art matters, and how the work will read under pressure.

A more disciplined process

The result is patent work that's faster, more transparent, and more disciplined without pretending that judgment can be automated away.
