PATENT-MPEP · PREMIUM PACK · $0.10 PER CITED ANSWER
AI patent research over the MPEP
The patent-mpep pack is a DEX expert pack: the USPTO Manual of Patent Examining Procedure, served to your AI agent over MCP. Ask a patent-examination question and it answers with the exact MPEP passage cited, or it refuses. Refusals cost $0.00.
What does the patent-mpep pack cover?
Eight chapters of the MPEP, the USPTO's own examiner manual (chapters 600, 700, 800, 1200, 1400, 1800, 2100, and 2700), chunked into 5,615 passages your agent can retrieve and cite. The recorded sessions below draw on Chapter 2100 (patentability): obviousness and combining references under MPEP §2143, and subject-matter eligibility under §101 / §2106.
- Cite-or-refuse. An answer returns only when retrieved passages clear an evidence threshold, and it carries the chunk key of the source. Otherwise the pack refuses instead of guessing.
- Public-record source. The MPEP is the public-record USPTO manual, curated by the founder from the primary source.
- Premium pricing. $0.10 per cited answer. Refusals are always $0.00. Everything is free during the private beta.
Examiner procedure from the public-record MPEP, not legal advice.
What does a real answer look like?
Three real recorded exchanges from the live pack, verbatim, including one the pack refused. The full nine-session record is on the transcripts page.
❯ Can an examiner combine two references to reject my claim as obvious?
Yes. An examiner can combine two or more references to reject a claim as obvious [ce9c25703350]. The limitations:
THE COMBINATION MUST BE RATIONALLY SUPPORTED — the examiner must present a convincing line of reasoning why a person skilled in the art would combine the references [c7c19f25050d].
IT CANNOT RENDER THE PRIOR ART INOPERABLE — the combination cannot change the primary reference's principle of operation [ce9c25703350, a82be9fd6403].
YOUR RESPONSE STRATEGY MATTERS — you cannot defeat a multi-reference rejection by attacking references in isolation; address the combination itself. …

❯ How does the USPTO analyze subject matter eligibility under §101?
The USPTO analyzes §101 eligibility with a two-step framework [ec4dd92903fb]:
STEP 1 — the claim must fall within a statutory category (process, machine, manufacture, or composition of matter).
STEP 2 (ALICE/MAYO) — 2A: is the claim directed to a judicial exception (abstract idea, law of nature, natural phenomenon)? 2B: if so, do additional elements supply an "inventive concept" — "significantly more" than the exception [ec4dd92903fb]?
THREE PATHWAYS TO ELIGIBILITY [ec4dd92903fb] — Pathway A: self-evident eligibility for claims where eligibility is obvious without detailed analysis. …

❯ Will my claim survive an Alice challenge in E.D. Texas?
REFUSED — the sources contain only USPTO examination guidance (MPEP Chapter 2100). They do not address litigation strategy or Eastern District of Texas rulings, so there is no basis for predicting whether a claim survives an Alice challenge in that venue.
