Pricing
Taking a startup invention from first disclosure to a filed application runs 19–25 attorney hours — about $10,000–$20,000 at typical rates, which is why most early-stage teams never file. SlingIP does the heavy pre-work upfront, so your attorney’s time drops to roughly 12 hours total — about 5 of which is reviewing SlingIP’s packaged deliverable (full scope below). That brings the legal fee down to the $4,000–$8,000 range — where seed and Series A companies actually file.
Upload up to two documents and SlingIP returns a one-page snapshot of the distinct concepts it extracted from them, each tied to specific passages in your own text. No payment required.
The full Invention Value Assessment Portfolio your attorney reads — typically 5–20 ranked candidates with prior-art checks, claim sketches, and, where available, a 60-minute virtual session with a registered patent agent.
Filing costs come from three separate places: the patent agent bills you directly under their own engagement letter, the USPTO charges its own official fees, and SlingIP charges a flat platform fee. SlingIP does not take a share of the agent fee.

Ranges reflect typical US patent-counsel fees of $10,000–$20,000 from first disclosure to a filed application. With SlingIP, that becomes roughly 12 attorney hours total to a filed application. Roughly 5 attorney hours to review the pre-packaged SlingIP deliverable — the ranked candidates, prior-art register, and flags — and to prepare the filing decision. This estimate covers review of the packaged materials only; it does not include independent prior-art searching, independent verification of the register, additional legal analysis, or claim drafting, which are separate. The remaining hours are claim drafting and filing craftsmanship SlingIP doesn’t replace — together bringing the legal fee to the $4,000–$8,000 range. Figures assume you bring your own counsel — the Filing Partner tier is a separate option. Your actual total depends on candidate count and counsel of record.
Scope
a pre-filing invention-screening and preparation tool that helps counsel assemble an attorney-ready package: ranked candidate inventions, a known-prior-art register, §101 and §112 issue flags for counsel's review, and the open questions counsel must resolve. SlingIP produces working material for a qualified practitioner; it does not itself render patent opinions.
not a comprehensive patentability opinion · not a novelty, non-obviousness, validity, enforceability, or infringement opinion on any patent (including the third-party patents in the prior-art register) · not a freedom-to-operate or clearance opinion · not filing-deadline or bar-date advice (SlingIP flags potential bar-date risk for counsel; it does not calculate or advise on statutory deadlines) · not legal advice — and using SlingIP or receiving its deliverable does not create an attorney-client relationship. Every legal determination, and every filing deadline, remains with your counsel.
Roughly 5 attorney hours to review the pre-packaged SlingIP deliverable — the ranked candidates, prior-art register, and flags — and to prepare the filing decision. This estimate covers review of the packaged materials only; it does not include independent prior-art searching, independent verification of the register, additional legal analysis, or claim drafting, which are separate.
SlingIP's prior-art register is built from the USPTO Open Data Portal (US patents), the Google Patents public dataset (BigQuery-sourced; used through a platform-maintained corpus drawn from selected patent classes and, for some subject areas, a keyword search), EPO OPS (European Patent Office Open Patent Services), Lens.org (patent and scholarly literature), and OpenAlex (academic / non-patent-literature). This search is bounded by those sources and their coverage and date windows; it is not exhaustive. In particular, recently-filed applications not yet published (typically within ~18 months of filing), non-English art, and material outside the named sources may not appear. The register is an input to counsel's analysis and to the applicant's duty of disclosure to the USPTO — not a substitute for either.
FAQ
No. SlingIP doesn't replace your attorney — it produces the disclosure your attorney needs to file. You bring your own counsel, or we can help connect you with an independent registered patent agent for the Filing Partner tier.
Everything you upload. We never claim rights to your inventions, never train AI models on your material, and never share your documents with third parties without your explicit authorization.
The preliminary scan is free. The full IVAP charges on delivery. Filing Partner is billed at engagement signing with the registered patent agent.
For repeat engagements (multiple inventions across a 12-month period), reach out — we discount per-portfolio fees in line with the working relationship.
