Patent Licensing Disputes: UK vs US
Patent licensing disputes usually arise when one party alleges breach of license terms, refusal to pay royalties, or improper use of patented technology. The approaches and legal frameworks differ in the UK and US, as do remedies and procedures.
1. UK Patent Licensing Disputes
Legal Framework
UK licensing disputes are governed by:
Patents Act 1977 (especially Sections 40–41 on infringement and licensing obligations)
Contract law principles (license agreements are contracts)
FRAND (Fair, Reasonable, and Non-Discriminatory) terms for standard-essential patents
Disputes are usually heard in:
High Court, Patents Court Division: for high-value, complex licenses
IPEC (Intellectual Property Enterprise Court): for smaller or simpler licensing cases
Key Features
FRAND obligations can create mandatory licensing disputes
Courts focus on contractual interpretation, compliance with license terms, and royalty payments.
Remedies include:
Injunctions
Damages
Accounting of profits
Declaratory relief
UK Case Examples
Case 1: Unwired Planet v Huawei (2017–2018)
Issue: FRAND licensing dispute over mobile patents
Facts: Huawei refused a global license, arguing Unwired Planet’s terms were unreasonable.
Outcome: UK High Court held Unwired Planet’s license terms were FRAND-compliant and enforceable worldwide.
Principle: UK courts can impose a global FRAND license if terms are fair and reasonable.
Case 2: Ericsson v D-Link (2014)
Issue: Alleged refusal to take FRAND licenses for standard-essential patents.
Outcome: Court emphasized good faith negotiations; injunction refused until D-Link engaged properly.
Principle: UK courts enforce FRAND principles but require parties to negotiate in good faith before litigation.
Case 3: Huawei v Conversant (2020)
Issue: Enforcement of FRAND obligations for SEPs.
Outcome: UK High Court allowed patent holder to obtain injunctions against non-compliant licensees.
Principle: FRAND-compliant licenses are enforceable, and refusal to take them can lead to injunctions.
Case 4: British Telecommunications v Proximus (2005)
Issue: Licensing dispute over telecom patents.
Outcome: High Court held Proximus breached licensing terms; damages awarded for unpaid royalties.
Principle: UK courts strictly enforce royalty payment obligations.
Case 5: Unwired Planet v Huawei II
Issue: Calculation of FRAND royalties.
Outcome: Court determined royalty rate per handset, considering global portfolio value.
Principle: Courts play an active role in quantifying fair royalties.
2. US Patent Licensing Disputes
Legal Framework
US disputes are governed by:
Patent Act, Title 35 USC
Contract law for licensing agreements
Antitrust law in some FRAND disputes
Litigation occurs primarily in:
District Courts (e.g., Eastern District of Texas, Northern District of California)
International Trade Commission (ITC) for import bans
US courts are more litigious, with heavy use of discovery and expert testimony.
Key Features
US courts allow enhanced damages for willful infringement
Injunctions under eBay Inc. v MercExchange (2006) require showing irreparable harm
Strong discovery rules can reveal licensing practices, royalty rates, and internal negotiations
US licensing disputes often involve portfolio-level analysis and multiple patents
US Case Examples
Case 1: Microsoft v Motorola (2012)
Issue: FRAND licensing dispute for video/audio SEPs
Outcome: US Court awarded Microsoft damages for overcharging; Motorola was bound by FRAND commitments.
Principle: US courts enforce FRAND commitments and determine reasonable royalty rates.
Case 2: Apple v Qualcomm (2019)
Issue: Dispute over mobile chipset patents and royalty overpayments
Outcome: Settlement reached after court threatened injunctions; Apple paid undisclosed royalties.
Principle: Licensing disputes can involve strategic settlements to avoid market disruption.
Case 3: Samsung v Apple (2012–2016)
Issue: Infringement and licensing terms for smartphone design patents
Outcome: Jury awarded Apple significant damages; complex cross-licensing negotiations followed.
Principle: US courts can enforce damages for breach of licensing terms and patent infringement simultaneously.
Case 4: Ericsson v D-Link (US parallel)
Issue: FRAND licensing enforcement in the US
Outcome: Court found FRAND obligations enforceable; damages calculated per unit sold.
Principle: US courts mirror UK’s FRAND approach but with more aggressive damages calculations.
Case 5: Rambus v Infineon (2008)
Issue: Licensing dispute over memory interface patents
Outcome: Court and ITC issued injunctions and damages; parties reached settlement.
Principle: US courts and ITC can issue import bans to enforce licensing rights, unlike the UK.
Case 6: Broadcom v Qualcomm (2005)
Issue: Portfolio-level FRAND licensing dispute
Outcome: Court set a portfolio-wide royalty rate, taking into account patent importance and market value.
Principle: US courts handle large-scale licensing disputes with detailed economic analysis.
