Five application elements
Specification, drawing, oath or declaration, filing fee, and the inventor's name — all present and compliant, or the filing does not release.
The most rigorous patent filing and prosecution service a foreign associate or startup can engage.
Patent Prosecution Filing Engine assembles a documentation-complete, examiner-ready U.S. utility patent application — every statutory element, every required search, the IDS, the claim set, formal drawings, and a prosecution calendar — checked against the letter of 35 U.S.C. and 37 CFR before a USPTO-registered practitioner signs and files it.

Why filings fail
A single missing element can delay or destroy patent rights.
A U.S. utility patent application is only as strong as the disclosure, claims, and filing procedure behind it. Miss one of the five statutory elements (specification, claim, drawing, oath, filing fee), skip a required prior-art search, mis-time a priority claim, or fail to file an IDS — and the application can be rejected, lose priority, or become unenforceable.
Most foreign associates and startups run this by hand, from memory, once or twice a year. The statute has not been read end-to-end since the last time it mattered. That is exactly where completeness gaps hide.
Patent Prosecution Filing Engine exists to close that gap with a single, exhaustive standard applied identically to every file.

missing application elements is enough to jeopardize patent rights
The benchmark
Measured against the letter of the statute — subsection by subsection.
We do not summarize the law and hope. Every filing is scored against a versioned rule pack tied to the exact text of 35 U.S.C. §111 and 37 CFR Part 1. These are the provisions each filing is held to.
Enablement and written description
The specification must enable a person skilled in the art to make and use the invention and describe the best mode — verified by deterministic checklist.
Definite claim set
Claims must particularly point out and distinctly define the invention. Claim scope is reviewed by a registered practitioner; formal defects are caught by deterministic gates.
IDS completeness
Every known prior art reference, including from foreign counterparts, must be disclosed. The IDS is built from search results and corroborated against inventor disclosures.
Duty of candor
All material information is disclosed to the USPTO. The duty is enforced by a completeness gate that flags missing references.
Priority chain verification
Any priority claim to a foreign or provisional application is verified for timeliness, chain continuity, and compliance with 35 U.S.C. §119 or §120.
How a filing is built
Intake to practitioner release, with deterministic gates the AI cannot overrule.
AI extracts and drafts. Deterministic rules — running as code, outside the model — decide what is complete. A USPTO-registered practitioner reviews and signs every filing. That order is never reversed.
01
Filing Gap Scan
Upload the invention disclosure or priority specification. We return a free completeness read: which statutory elements and searches you already have, and which are missing.
02
Prior-art & assignment searches
As your authorized clerical agent, we order prior-art, U.S. assignment, and foreign counterpart searches and build the IDS and assignment chain, corroborated across sources.
03
Grounded drafting
The specification, claims, abstract, and drawings are drafted from your validated disclosure and the 35 U.S.C. rule pack into field-locked templates — no legal opinions, no invented facts.
04
Deterministic completeness gates
All five statutory elements are checked; enablement and definiteness are verified by checklist; the IDS is resolved; priority claims are validated. Any failure blocks release.
05
Practitioner review & signature
A USPTO-registered practitioner reviews the application, sets claim scope, and signs the oath or declaration. High-value or complex cases route to a senior practitioner.
06
Delivery
You receive the filing: specification, claims, drawings, IDS, signed oath, filing receipt, and a prosecution calendar — ready for the applicant to review and authorize filing.

Why Patent Prosecution Filing Engine
Built to be the most thorough option a foreign associate or startup has.
Documentation-complete, by design
The deliverable is completeness itself — every statutory element and search accounted for or explicitly exception-coded. Nothing is left implicit.
Deterministic, not vibes
The gates that decide completeness are code, not a model's opinion. A drafting error cannot slip past a statutory requirement.
In its lane, on purpose
We prepare documentation and run searches as your clerical agent. We never give legal advice on patentability or strategy; the practitioner sets claim scope.
Engagement
Flat fee, per filed application. No hourly billing, ever.
Simple, predictable, and aligned with a documentation standard — not a cut of any recovery.
- A free Filing Gap Scan before you commit — see exactly what is missing.
- One flat fee per filed utility application; disclosed pass-through search and USPTO fees.
- Optional fixed-fee Office Action response per action.
- Optional allowance milestone bonus for successful grant.
FAQ
Questions, answered precisely.
Is Patent Prosecution Filing Engine a law firm?
No. Patent Prosecution Filing Engine, a service of Your Deputy, Obuke LLC, provides documentation-completeness services. It is not a law firm, does not provide legal advice, and does not represent you in any legal matter. A USPTO-registered practitioner reviews and signs all filings.
Do you give patentability opinions or legal advice?
No. We prepare the application documentation and run searches as your clerical agent. Claim scope and strategy are set by the reviewing practitioner. We do not opine on patentability or infringement.
What makes a filing 'complete'?
Completeness is defined by the statute: the five §111(a)(2)(A) elements present, enablement and definiteness verified, IDS resolved, priority chain validated, and practitioner signed. Deterministic gates enforce each one before release.
How fast is it?
The standard SLA is five business days from complete intake to a practitioner-ready draft. The free Gap Scan is returned much sooner and tells you exactly what is still needed.
How are you priced?
A flat fee per filed application, plus disclosed pass-through search and USPTO fees. No hourly billing. Office Action responses and allowance milestones are separately priced.
