Patent Licensing

Cross-License

Two companies each needing the other's patents grant each other licenses — avoiding infringement suits, resolving blocking patent situations, and enabling both parties to compete freely. Financial balancing payments equalize portfolio value.

What is a cross-license and how does it work?

A cross-license is a bilateral (or multilateral) patent license agreement in which each party grants the other party (or parties) the right to use its patent portfolio — or a defined subset of it — in exchange for reciprocal rights to the other's patents..

How it Works

  • Party A owns patents that Party B needs to practice its technology
  • Party B owns patents that Party A needs
  • Instead of each suing the other for infringement, they negotiate a cross-license
  • The license grants each party the right to make, use, sell, and import products covered by the other's patents
  • Financial balancing payments (royalties or lump sums) flow in one direction if the portfolios have unequal value

Resolution of Blocking Patents. Cross-licenses are the primary resolution mechanism for blocking patent situations — where a pioneer patent and an improvement patent each prevent the other's owner from practicing the improved technology

Industry-wide Use

  • Nearly every major technology company participates in cross-license programs
  • IBM has cross-licenses with hundreds of companies covering most of its foundational technology portfolio
  • Qualcomm, Ericsson, Nokia, InterDigital, and others have extensive cross-licensing programs with device manufacturers

Scope

  • Cross-licenses are typically defined by: (a) PATENT PORTFOLIO SCOPE — which patents are licensed (all patents, a specific field, patents filed before a date)
  • (b) FIELD OF USE — what the recipient can do with the licensed patents
  • (c) TERRITORY — geographic coverage
  • (d) TERM — how long the license runs
  • (e) SUBLICENSING — whether the licensee can sublicense to affiliates or third parties.

How is a cross-license valued and balanced?

Cross-license valuation is one of the most complex aspects of IP strategy — particularly when portfolios are unequal in size or value.

Portfolio Valuation Methods

(1) Counting Approach

  • Count patents in each portfolio and compare
  • Crude but common in initial negotiations

(2) Claims Approach

  • Count the claims most likely to be infringed by the other party's products
  • Broader, more targeted claims are worth more than narrow or weak patents

(3) Royalty Rate Approach

  • Calculate what each party would charge the other for a unilateral license at arm's length
  • The net difference (after offsetting the parties' cross-royalties) is the balancing payment

(4) Comparable Transaction

  • Look at comparable licenses in the same technology space
  • FRAND rates, industry standard rates, or prior arm's-length licenses

(5) Litigation Risk-weighted Value

  • Consider the probability each patent would survive validity challenge and be found infringed
  • Discount portfolio value by invalidity risk

Financial Balancing

  • If Party A's portfolio is worth $50M/year in license fees and Party B's is worth $20M/year, the cross-license might require Party B to pay a 'balancing royalty' of $30M/year (the difference)
  • Alternatively, the parties negotiate a lump-sum settlement for a defined period

Most Favored Licensee (MFL) Clauses

  • A party may insist on an MFL clause — if either party later grants a more favorable license to a third party, the cross-licensee gets the same terms
  • This prevents a party from signing a low-value cross-license and then offering a more valuable license to a third party
  • MFL clauses complicate future licensing negotiations.

What are the key provisions in a cross-license agreement?

Cross-license agreements are complex commercial contracts with several provisions that require careful negotiation.

(1) Grant Clause

  • Defines what each party is receiving — make, use, sell, import rights
  • Within a specific field of use
  • Within specific territories
  • Under specific patents or patent families

(2) Portfolio Definition

  • Which patents are included (all patents as of the effective date; patents filed before a certain date; patents in a specific technology field)
  • Whether future patents are included
  • How acquired patents are treated

(3) Term

  • Typically co-extensive with the life of the licensed patents
  • Renewable
  • Subject to termination provisions

(4) Financial Terms

  • Balancing royalties (running or lump sum)
  • Payment currency
  • Audit rights
  • Interest on late payments

(5) Grantback Clauses

  • Whether each party must license future improvements under the same cross-license
  • Grantback provisions may be MANDATORY (automatic license to future improvements) or OPTIONAL
  • Mandatory grantbacks are scrutinized under antitrust law (may be coercive if the stronger party imposes on a weaker licensee)

(6) Sublicensing Rights

  • Whether the licensed rights extend to subsidiaries and affiliates (usually yes)
  • Whether third-party sublicensing is permitted (usually no without consent)

(7) Infringement History Release. A release of past infringement claims — defines the cutoff date and scope of claims released

(8) Assignment

  • Typically not assignable without consent except with the entire business
  • Bankruptcy issues — § 365(n) elections by licensees if licensor goes bankrupt

(9) Audit Rights. The right to audit the other party's royalty-bearing activities

(10) Dispute Resolution

  • Arbitration or litigation
  • Governing law and venue.

What are antitrust concerns with cross-licensing?

Cross-license agreements can raise antitrust concerns if they are used to allocate markets, fix prices, or exclude competition.

Legitimate Vs. Anticompetitive

  • Most cross-licenses are procompetitive — they allow both parties to use each other's technology, produce better products, and compete
  • Courts and regulators generally view cross-licenses favorably

Potential Antitrust Issues

(1) Market Allocation. If a cross-license includes provisions where each party agrees to stay out of certain product markets or geographies, this is naked market allocation — per se illegal under Sherman Act § 1

(2) Price-fixing

  • If cross-licensees agree on licensing rates for third parties (coordinating their licensing terms), this can be price-fixing
  • Patent pools with cartel-like pricing structures raise similar concerns

(3) Exclusionary Effects. If a cross-license between dominant players effectively excludes smaller players who lack patents to trade, it can be exclusionary

(4) Mandatory Grantback Coercion. Requiring a licensee to grant back all future improvements to the licensor for free — particularly when the licensor is dominant — can deter the licensee from investing in R&D

Regulatory Scrutiny

  • DOJ Antitrust Division and FTC have guidelines on patent cross-licenses and pools
  • EU competition law (Article 101 TFEU) and Technology Transfer Block Exemption Regulation (TTBER 316/2014) apply to cross-licenses in EU

SAFE Harbor

  • Cross-licenses between non-competitors generally receive lighter scrutiny
  • Cross-licenses between competitors in the same field receive more scrutiny, particularly for market allocation and grantback provisions.

How are cross-licenses negotiated in practice?

Cross-license negotiations are often multi-year processes involving technical, legal, and business teams.

Initiation

  • Typically begins with a 'patent assertion' or 'patent notice letter' from one party to another
  • The recipient responds by asserting its own portfolio — establishing the basis for negotiation
  • Sometimes begins with litigation — cross-licenses often resolve patent suits between large technology companies

Negotiation Process

(1) Portfolio Review. Each party's patent team reviews the other's portfolio to assess relevance, breadth, validity, and coverage of the counterparty's products

(2) Claim Charts. Each party maps the other's patents to its own products to establish infringement exposure

(3) Valuation. Both parties independently value the portfolios and develop financial proposals

(4) Business Judgment

  • Senior business leaders decide whether to pay a balancing royalty or fight (litigation)
  • The value of avoiding litigation, maintaining product launches, and preserving business relationships drives this decision

Negotiation Tactics

(1) Portfolio Building Leverage. Companies that invest in R&D and file patents have more leverage in cross-license negotiations — more patents to trade

(2) Claim Quality. A smaller portfolio with strong, clearly-infringed claims may outvalue a large portfolio of weak patents

(3) Litigation as Leverage. Filing a lawsuit (or threatening one credibly) accelerates negotiations

(4) Industry Norms. In semiconductor, wireless, and computing industries, cross-licensing is so standard that the negotiation focuses on financial balancing, not whether to cross-license

Conclusion. Typically, a multi-year Agreement for Cross-License of Patents covering both parties' relevant patent portfolios, with financial terms, release of past claims, and a term extending to patent expiry.
