Patent brokerage is the professional facilitation of patent sales between inventors or patent owners on one side, and corporate buyers — typically manufacturers, technology companies, or patent assertion entities — on the other.
The analogy to real estate brokerage is imperfect but useful. Like a real estate broker, a patent broker brings market knowledge, a network of potential buyers, and negotiation expertise to a transaction that most sellers could not execute effectively on their own. Unlike real estate, the patent market has no public listings, no published comparable prices, and no standardized transaction process. That opacity is precisely why brokers exist.
The brokerage process typically involves several phases:
Evaluation. Before agreeing to represent a patent, a broker assesses whether it is commercially viable. This includes reviewing claim scope, the prosecution history, the technology sector's activity level, and whether identifiable buyers are likely to exist. Not every patent is sellable, and a reputable broker will tell you honestly if yours is unlikely to find a buyer at a meaningful price.
Packaging. If the broker agrees to represent the patent, they prepare marketing materials — typically a blind profile that describes the technology and claims without initially identifying the patent number, to protect the seller's negotiating position before NDAs are in place.
Buyer identification. The broker uses their network, patent databases, and commercial intelligence to identify corporations that are likely to value the patent. This may include companies already using the patented technology (potential infringers), companies in adjacent spaces, and strategic patent acquirers who build portfolios in specific technology sectors.
Outreach and qualification. The broker contacts potential buyers, gauges interest, and manages the NDA process that allows detailed due diligence to occur confidentially.
Negotiation and closing. Once a buyer is engaged, the broker negotiates price and deal structure on the seller's behalf and coordinates with legal counsel to execute the assignment agreement and record it with the relevant patent offices.
Patent brokers work almost exclusively on a commission basis — a percentage of the sale proceeds paid upon closing. Commission rates vary, but 10-15% is common for individual patents. Some brokers also charge an upfront retainer to cover their evaluation and marketing costs, particularly for patents that may require significant work to package and present.
Commission-only arrangements align the broker's incentives with the seller's: the broker only earns if the patent sells. This is generally preferable for inventors, though it also means brokers are selective — they will only take on patents they believe they can sell.
The patent brokerage industry ranges from highly experienced former patent attorneys with deep corporate buyer networks to individuals with little more than a website. When evaluating a broker, ask specifically about closed transactions in your technology sector, how many buyers they will approach, and what their typical timeline to close looks like.
A broker who refuses to give you references or cannot point to specific closed transactions in a relevant technology area is a concern. The value of a broker is almost entirely in their buyer access and negotiation track record.
Working with a patent broker makes sense when you do not have existing relationships with corporate patent buyers, when you lack the time to run a structured sale process yourself, and when the patent has sufficient commercial potential that the broker's commission is justified by the incremental value they bring.
For patents with very low expected sale prices — under $50,000 — brokerage may not be economical, as the commission would consume a large portion of the proceeds. For patents with significant upside, a broker's ability to run a competitive process with multiple buyers can add far more value than their commission costs.
