Patent Quality

Know if it's patentable —
and who got there first.

Patent Quality does two things. First, it assesses whether your invention is patentable — eligibility, novelty, non-obviousness and disclosure — with the reasoning an examiner would apply. Second, it surfaces every similar idea already public: granted patents, published applications, papers, and open-source code, mapped claim by claim.

Part 1 · Is it patentable?

The four tests every examiner applies — scored before you file

Claude reads your invention disclosure or draft claims and evaluates them against the statutory requirements of 35 U.S.C., with a written rationale for each score so counsel can check the reasoning, not just the number.

35 U.S.C. §101

Subject-Matter Eligibility

Runs the Alice/Mayo two-step analysis — is the claim directed to an abstract idea, and if so, does it recite an inventive concept or practical application? Scored twice — against USPTO examination practice (2024 AI eligibility examples, Ex parte Desjardins) and against Federal Circuit precedent (Recentive v. Fox), because the two currently diverge for ML claims.

35 U.S.C. §102

Novelty

Checks whether any single prior-art reference discloses every element of a claim. Flags your own public disclosures — talks, preprints, blog posts, public repos — and the one-year U.S. grace period they start.

35 U.S.C. §103

Non-Obviousness

Looks for combinations of references a skilled practitioner would plausibly join, following the Graham factors and KSR. Highlights which claim elements carry the inventive weight — and which are routine.

35 U.S.C. §112

Enablement & Definiteness

Tests whether the description supports the full scope of the claims and whether claim terms are definite. Catches functional "black box" ML language that commonly draws written-description rejections.

EPO · Art. 52–56

International Readiness

Flags issues for absolute-novelty jurisdictions and the EPO's technical-character and problem-solution approach, so a U.S. filing doesn't foreclose protection abroad.

Inventorship

AI-Assisted Inventions

Inventors must be natural persons (Thaler v. Vidal), and under the USPTO's November 2025 guidance AI is treated as a tool. Records which human conceived each claimed element — and what the AI contributed.


Part 2 · What already exists?

Every similar idea that's public — patents, papers and code

Patent-only searches miss where AI innovation is actually published. Patent Quality searches patent offices, the research literature and open-source repositories together, then de-duplicates patent families so you review each invention once.

Semantic + Classification Search

Embedding search finds references that describe the same idea in different words; CPC classification codes and keyword queries catch what embeddings miss.

🧩

Claim Charts

Each independent claim is split into elements and mapped to the passages in each reference that disclose them — the format attorneys and examiners already use.

🕸️

Citation Graph Expansion

Follows forward and backward citations from the strongest hits to find related art a single query would never reach.

🗺️

Landscape & White Space

Clusters the results by approach and assignee, showing who is active in your area — and the gaps where a narrower claim is still open.


How It Works

From disclosure to decision-ready report

1

Submit

Paste an invention description or draft claims, or send a candidate from Patent Feasibility.

2

Search

Parallel search across patent offices, literature and code; families de-duplicated.

3

Chart

Claim elements mapped to the closest references, with overlap scores.

4

Assess

§101 / §102 / §103 / §112 scores with written rationale and suggested claim narrowing.

5

Hand off

Export a PDF for counsel. Reports are kept in confidence, never published.

Patent Quality is a decision-support tool for inventors and patent counsel. It does not provide legal advice or a legal opinion on patentability, and does not replace review by a registered patent attorney or agent.
