The invention
Patent PreCheck is a software process that: (1) summarizes uploaded invention text with an LLM, (2) embeds that summary and searches a vector index of prior art, (3) scores patentability across §101 eligibility, §102 novelty, §103 non-obviousness, and filing-readiness documentation, and (4) returns pillar-level findings in plain English.
We submitted a representative excerpt — the analyze Lambda handler plus the patentability engine interface — not marketing copy.
What the free score showed
The free tier returned two headline scores plus a key diagnosis calling out the weakest pillar. For our stack, non-obviousness (§103) was the limiter: the combination of vector retrieval + LLM scoring sits in a crowded field of “AI patent analytics” patents and published applications.
- §102 novelty — Stronger: the specific tier-gated response shape and client-minted report IDs are differentiated implementation choices.
- §103 non-obviousness — Weakest: embedding-first prior art + interactive human/AI contribution coaching is the combination we needed to document clearly.
- Filing readiness — Moderate: architecture docs existed internally but were not yet in the submission text.
We emailed the report to ourselves using the free score capture form — same report ID on screen and in inbox — so we could revisit it without a paid account.
What changed after the $69.95 review
The Interactive Code Review is where we turned diagnosis into edits:
- Added explicit human-directed vs. AI contribution declarations at analyze time (USPTO-aligned framing).
- Expanded the invention summary to describe the technical effect of tier-gated prior art retrieval, not just “we use AI.”
- Documented the legal-intelligence layer as a separate, rule-bound module — strengthening §101 eligibility narrative.
- Exported a dated PDF with report ID for our own records before investor conversations.
Scores moved on the filing-readiness pillar first (documentation), then patentability band — exactly the workflow we built for customers.
Why we publish this
Most inventors never see how an attorney would frame their work until they spend thousands. We use our own product the same way our customers do: free directional score → optional deep review → attorney handoff. No fabricated testimonials — this is our actual product loop.
