Patent Transactions

Patent Brokerage

Patent brokers match sellers to buyers, prepare claim charts, manage NDA processes, and structure transactions from teaser to recorded assignment — typically earning 10–25% of the sale price.

What does a patent broker do and when should you use one?

A patent broker is an intermediary who facilitates patent transactions — matching sellers to buyers and guiding both parties through the transaction process.

What a Patent Broker Does

  • (a) SELLER ENGAGEMENT: the broker evaluates the patent portfolio, assesses market value, and determines whether the patents are marketable
  • Not all patents are worth brokering
  • (b) PORTFOLIO PREPARATION: brokers prepare marketing materials including patent claim charts, landscape analyses showing competitive positioning, and licensing revenue history
  • (c) BUYER IDENTIFICATION: brokers maintain relationships with likely buyers — operating companies in the relevant technology space, portfolio companies, defensive aggregators (RPX, Unified Patents), and PAEs
  • (d) BLIND PACKAGES: brokers typically send teaser packages (which identify the patent numbers and technology area but not always the seller) under NDA
  • (e) DEAL NEGOTIATION: brokers structure the transaction, negotiate price and terms, and guide the parties through due diligence
  • (f) CLOSING: brokers coordinate the execution of patent assignment agreements and the transfer of consideration

When to Use a Broker

  • (a) when your company is divesting non-core IP and lacks an internal IP monetization team
  • (b) when a startup or inventor wants to sell patents but doesn't have buyer relationships
  • (c) when a company exits bankruptcy and its IP assets must be liquidated
  • (d) when an operating company wants to build a portfolio defensively and needs to source assets

Broker Compensation

  • Sellers typically pay a success fee (commission) of 10-25% of the transaction value
  • For smaller transactions (<$1M), commissions may be higher
  • Some brokers also charge retainers or minimum fees

Alternatives to Brokers. Companies with established IP teams sometimes sell directly to known buyers or through patent auctions (Ocean Tomo, Richardson Oliver) instead of engaging a broker.

How does a patent seller prepare for a brokered sale?

Preparation before engaging a broker significantly affects sale price and buyer interest.

Step 1 — Portfolio Assessment

  • Identify which patents are candidates for sale
  • Key factors: (a) remaining patent term (patents with less than 2-3 years of life have limited value)
  • (b) claim breadth (broad claims covering widely used technology are most valuable)
  • (c) forward citation count (heavily cited patents are often more foundational and more valuable)
  • (d) prosecution history (clean prosecution = easier licensing; heavily amended claims with narrow scope = less valuable)
  • (e) whether the patent covers a product or process currently in widespread commercial use

Step 2 — Claim Charts

  • Prepare claim charts showing how the patent claims read on accused products in the market
  • Buyers want to see that the patent claims map to real products
  • Claim charts are often the single most important factor in buyer interest

Step 3 — Licensing History

  • Compile any existing licenses, settlement agreements, and licensing revenue
  • Buyers pay a premium for patents with an established licensing track record

Step 4 — Title Chain

  • Ensure clean title — all inventors assigned their rights, all employees signed PIIAs, all prior owners in the chain recorded at the USPTO
  • Title problems kill deals

Step 5 — Encumbrances

  • Identify any licenses, covenants not to sue, or FRAND commitments that limit who the buyer can assert the patent against
  • Buyers heavily discount patents with broad license encumbrances

Step 6 — Valuation

  • Get an independent valuation or at minimum a comparable transaction analysis
  • Understand the market before engaging a broker to avoid undervaluing.

What does the patent sale process look like from teaser to closing?

A typical patent brokerage transaction follows a structured process: PHASE 1 — ENGAGEMENT (weeks 1-4): seller engages broker; broker evaluates portfolio; engagement letter executed (sets commission rate, exclusivity period, often 90-180 days); PHASE 2 — MARKETING MATERIALS (weeks 2-6): broker prepares teaser (blind package — does not identify seller; identifies technology; may include patent numbers); full package (prepared for buyers who sign NDA; includes claim charts, landscape analysis, licensing history, title analysis); PHASE 3 — BUYER OUTREACH (weeks 4-12): broker sends teasers to curated list of potential buyers; receives NDA requests; shares full package with NDAs executed; receives indications of interest (IOIs); PHASE 4 — DUE DILIGENCE (weeks 8-16): interested buyers conduct: (a) claim construction analysis; (b) freedom-to-operate analysis (does the patent cover the buyer's existing products?); (c) validity analysis (prior art search); (d) title chain review; (e) encumbrance review; PHASE 5 — BIDS AND NEGOTIATION (weeks 10-18): broker sets a bid deadline; receives bids; negotiates with top bidders; may conduct a 'best and final offer' round;.

Phase 6 — Loi and Exclusivity

  • Winning bidder submits a letter of intent (LOI)
  • Seller grants exclusivity for final due diligence and documentation
  • PHASE 7 — CLOSING (weeks 16-24): negotiate and execute patent assignment agreement
  • Buyer pays purchase price
  • Seller executes patent assignments (one per patent family)
  • USPTO assignment recorded within 3 months
  • Closing typically takes 2-4 weeks after LOI

Typical Timeline. 4-6 months from engagement to close (larger portfolios can take 9-12 months).

How is patent value determined in a brokered transaction?

Patent valuation in transactions is part science, part art — and ultimately a negotiation.

Valuation Approaches

  • (a) INCOME APPROACH: the most commonly used
  • Project future licensing income the patent could generate
  • Discount to present value
  • Requires assumptions about royalty rate, royalty base (how many potential infringers?), likelihood of licensing success, and discount rate
  • (b) MARKET COMPARABLE APPROACH: look at prices paid for similar patents in comparable transactions
  • Difficult because most patent transactions are confidential
  • Data sources include Richardson Oliver Intelligence, Cipher transaction databases, and published court-ordered sale records
  • (c) COST APPROACH (rarely used): what it would cost to recreate the patent portfolio
  • Least relevant for established portfolios

Key Value Drivers

(1) Claim Breadth and Clarity. How broad is the independent claim? Does it cover current technology or only legacy approaches?

(2) Product Coverage. Do the claims read on commercially significant products currently in use?

(3) Remaining Term

  • 20-year term from filing date
  • A patent with 15 years remaining is far more valuable than one with 3 years

(4) Forward Citation Count. Heavily cited patents are often foundational and more valuable

(5) Licensing History

  • Established royalty rate evidence
  • Settled cases validate the patent's assertion value

(6) Claim Mapping Quality. Are there strong claim charts showing infringement of widely deployed products?

(7) Encumbrances. Prior licenses, covenants not to sue, FRAND commitments dramatically reduce value

Buyer Type Affects Price

  • Operating company defensive buyer — values patent as a deterrent
  • May pay a defensive premium
  • PAE buyer — values patent on its assertion potential
  • Typically pays 2-5x annual potential licensing revenue
  • Patent pool / aggregator — values based on pool membership pricing models.
