We don't list patents. We sell them.
List a patent on a marketplace and you get visibility. List it with EX-IX and you get a process — valuation, buyer targeting, controlled outreach, and deal support to close. M&A-style execution for an asset class that's never had it.
Patent marketplaces operate like classified ads — post, pay the listing fee, wait. When nothing happens, the platform tells you the market is "illiquid." That's not a market problem. It's a process problem. EX-IX operates like a patent M&A firm.
Real estate has a listings site for visibility and a broker for the sale. Patent marketplaces try to be both and succeed at neither. EX-IX is the broker — the one who knows the buyer, values the asset, and gets the deal done.
Why most patent listings never sell
A large share of patents listed on open marketplaces never transact — not because no one wanted them, but because the seller didn't know what they had and the buyer didn't trust what they saw. Before a patent reaches a buyer through EX-IX, it goes through digital-twin simulation: physics-grade claim reconstruction, detectability analysis, and validity probability, benchmarked at 0.76% mean absolute percentage error against real-world outcomes.
We do not take patents that won't sell, and we do not price them by guesswork. Buyers come to EX-IX knowing every asset they see has been pre-vetted — and that trust closes deals.
The real bottleneck isn't demand — it's discovery
A corporate IP team managing hundreds or thousands of patents is not browsing listings — it moves only when someone shows it a patent that fills a gap it already knows it has. For every asset we take on, EX-IX builds a buyer target list from:
- Companies patenting in the same technology classes within the last 24 months
- Gaps in their filing patterns that your independent claims fill
- Priority dates that give you seniority over their recent applications
- Budget proxies — R&D spend, acquisition history, and licensing patterns in their space
Then we reach out — not a blast, a curated shortlist, each sent an anonymous teaser explaining exactly why the patent matters to their portfolio. This is how M&A works: a company doesn't list itself for sale on a bulletin board, a banker calls the buyers who need it most. EX-IX does the same for patents.
Validation & Pricing
Digital-twin simulation, claim scope mapping, and comparable-transaction pricing — so you know what your patent is worth before it goes to market.
Positioning
A full confidential information memorandum: the problem, the mechanism, the market, the whitespace, the enforcement story, the design-around analysis.
Targeting & Outreach
A ranked buyer list and curated, anonymous teasers sent directly to the companies whose portfolio gaps your claims fill.
Process Management
NDAs, a virtual data room, management conversations, and structured bids with clear timelines through to final offers.
Close
Title search, assignment recording, and escrow. We get paid on close — a success fee, not a fee to be seen.
Patents that can benefit from active targeting rather than passive listing. The large brokers work the biggest deals because they need the commission to justify their overhead; open marketplaces serve the long tail that almost never sells. The gap between them — individual inventors, university spinouts, and small companies with one or two genuinely valuable patents — is where the friction is highest and the service is worst. If your patent has been sitting on a marketplace with no offers, the problem isn't your patent. It's the process.
