LLM-powered

Prior Art Search

LLM-powered prior art search

Large language models (LLMs) accelerate how we structure prior-art review against independent limitations—so your team spends less time on tabular drafting and more time on claim construction, experts, and theory. Deliverables are technical mapping drafts for your review—not a substitute for brief writing or advocacy.

Why LLMs here

Speed without pretending the machine is counsel

We use LLM-powered workflows to produce consistent, review-ready drafts. We do not draft legal doctrine (for example, no motivation-to-combine narratives, KSR-style storytelling, or analogous-art arguments). Uncertain technical matches are flagged for human review—because a wrong “yes” costs more than an honest “review this.”

Embeddings

Embeddings turn patent text into a mathematical “meaning map.” In a crowded prior-art set, that helps you reach the right paragraphs sooner for a given limitation—faster first pass, fewer missed corners—without claiming perfect recall or “zero miss” search.

Frontier models

Today’s frontier LLMs are strong at structured outputs, long-document comparison, and stable tabular formatting. We use that to accelerate matrices and chart drafts you can take into a prep call with inventors, experts, or co-counsel—not to replace claim construction or courtroom judgment.

What you should expect

  • Draft-style disclosure matrices, claim-chart style writeups, and gap tables aimed at technical mapping.
  • Independent-claim focus aligned with how your invalidity prep often starts.
  • Explicit boundaries: Patent counsel and agents retain review, legal strategy, and advocacy.

Service scope

Invalidity & IPR/EPR support—not a general patent shop menu

We focus on U.S. patent invalidity and IPR/EPR-oriented technical support and technical claim mapping for independent claims. This offering is not framed as clearance / FTO, portfolio monitoring, or prosecution services.

Typical workflow (high level)

  1. Intake: patent number, goals, and any constraints you want honored.
  2. Technical mapping pass: candidate references structured against independent limitations.
  3. Review package: drafts you can mark up, challenge, and fold into your legal theory.

Timelines and deliverable formats are confirmed after intake—this page is not a binding services contract.

Deliverables

Built for counsel and agent review

Structured matrices & charts

Outputs emphasize limitation-by-limitation visibility—so teams can align quickly on what the references actually say, before you invest in full brief mechanics.

Visual summaries

Coverage-style views (where helpful) to communicate “where the paper is” across references and limitations—useful in prep sessions with inventors, experts, and co-counsel.

Sample redlines or anonymized excerpts may be available on request—request them by email.

Why teams reach out

More time for arguments only humans should make

  • Less manual table-building and paragraph hunting on tight schedules.
  • A shared artifact set your group can annotate, split, and stress-test.
  • A disciplined technical lane: mapping and labeling—not outcome guarantees.

Practice & methodology

Long-page clarity: scope, process, and human review

Credible patent-search sites read like experienced teams: clear scope, visible process, and an honest account of where humans step in. We follow that structure—without borrowing anyone else’s copy—then keep the lane narrow: LLM-powered technical mapping under your direction.

Not a law firm

Prior Patent Search provides technical mapping support under the direction of your retained counsel or registered patent agent. We do not provide legal representation. Engagements are confirmed in writing after intake—scope, timing, and deliverables—so expectations stay explicit.

Human-in-the-loop quality posture

Model output is treated as draft material: structured for repeatability, checked for internal consistency, and marked where the technical read is uncertain. The goal is work product you can challenge efficiently—not slides that pretend certainty.

Who we serve

Serving teams who work in references and limitations

We work with patent litigators, registered patent agents, and IPR/EPR support teams who need structured technical drafts—not generic “AI search” interfaces.

Anonymous client snapshots (illustrative)

We do not publish client names without permission. Representative situations include: a hardware-heavy IPR/EPR petition support package; a software patent invalidity prep sprint ahead of a Markman-heavy schedule; and a second-chair technical mapping pass for trial teams managing multiple references.

For quality control, we treat model output as drafts—structured for repeatability—while keeping professional review at the center of what ships to your matter teams.

Important

Not legal advice

Prior Patent Search provides technical analysis drafts intended for review by qualified U.S. patent counsel or registered patent agents acting within their role. Nothing on this site is legal advice, and nothing here predicts outcomes at the PTAB, in district court, or in prosecution.
