Patent Licensing Fundamentals

Patent licensing transfers rights to practice inventions protected by patents without transferring ownership of the underlying intellectual property. Licensors retain their patents while licensees gain authorization to make, use, sell, or import products incorporating patented technology. This arrangement enables technology owners to monetize innovations while allowing others to build on them.

Licensing terms vary widely depending on the technology, market conditions, and parties' relative bargaining positions. Exclusive licenses grant sole rights to specified uses, potentially commanding premium payments. Non-exclusive licenses allow multiple parties to practice the same technology, typically at lower per-license fees. Field-of-use restrictions limit licensed rights to particular applications or markets. Geographic limitations restrict licensed activities to specified territories.

Royalty structures determine how licensees compensate licensors for technology access. Running royalties, calculated as percentages of licensee revenue or per-unit fees, tie payments to commercial success. Lump-sum payments provide fixed compensation regardless of commercial outcomes. Minimum royalty commitments ensure baseline returns while preserving upside potential. Hybrid structures combine elements to balance licensor and licensee interests.

The electronics industry's patent licensing practices have evolved through decades of experience. Early radio industry patent disputes established precedents for licensing arrangements. The semiconductor industry's cross-licensing practices enabled broad technology access while managing patent thickets. Software and telecommunications industries have developed their own licensing conventions reflecting the characteristics of those technologies.

Trade Secret Licensing

Trade secret licensing transfers confidential business information under contractual protections. Unlike patents, which publish the inventions they protect, trade secrets maintain protection through confidentiality. Trade secret licenses authorize recipients to use confidential information while imposing obligations to maintain its secrecy.

Manufacturing process knowledge frequently transfers through trade secret licensing. Semiconductor fabrication processes, for example, depend on countless parameters and techniques that cannot practically be fully documented in patents. Transferring effective manufacturing capability requires sharing this tacit knowledge, which trade secret licenses enable while providing legal protections against unauthorized disclosure.

Trade secret licenses typically include extensive confidentiality provisions. Licensees must restrict access to authorized personnel, implement security measures meeting specified standards, and prevent unauthorized copying or disclosure. These obligations often survive license termination, continuing to protect the information even after the business relationship ends.

The combination of patent and trade secret licensing often provides more comprehensive technology transfer than either alone. Patents establish clear legal rights enforceable against third parties. Trade secrets fill gaps in what patents can protect, particularly regarding manufacturing know-how. Together, they enable effective technology transfer while maintaining appropriate protections.

Software Licensing Models

Software licensing has developed distinctive models reflecting the unique characteristics of software as intellectual property. Copyright protection, supplemented by patents in some jurisdictions, establishes the legal basis for software licensing. The ease of copying software creates both opportunities and challenges that shape licensing practices.

Proprietary software licenses restrict users' rights while granting limited authorizations for specified uses. End-user license agreements (EULAs) typically authorize installation and execution while prohibiting copying, modification, or reverse engineering. Enterprise licenses enable organization-wide deployment under negotiated terms. Development licenses authorize incorporation of licensed technology into licensees' products.

Open-source licenses take fundamentally different approaches, granting broad rights while imposing conditions on redistribution. The GNU General Public License (GPL) requires that derivative works be licensed under compatible terms, ensuring continued openness. The MIT and BSD licenses impose minimal conditions, enabling incorporation into proprietary products. Apache and similar licenses address patent rights alongside copyright. These varied approaches have enabled the open-source movement's substantial contributions to electronics software development.

Software-as-a-service (SaaS) models have modified traditional licensing approaches. Rather than licensing software for local installation, SaaS providers deliver functionality through network access. Terms of service replace traditional licenses, governing use of remotely hosted capabilities. These models have transformed how software technology reaches users while raising new questions about technology access and control.

Technology Development Joint Ventures

Joint ventures for technology development combine resources and expertise to pursue innovations that neither partner could achieve alone. Partners contribute funding, personnel, facilities, or existing intellectual property according to negotiated arrangements. Resulting innovations typically become jointly owned or are allocated according to predefined formulas.

The semiconductor industry has extensively utilized development joint ventures. IBM's partnership with Sony and Toshiba to develop the Cell processor combined American design expertise with Japanese manufacturing capability. ASML's development partnerships with Intel, Samsung, and TSMC have enabled extreme ultraviolet lithography advancement through shared investment and risk. These collaborations have enabled progress that the enormous costs of leading-edge semiconductor development would otherwise have precluded.

Managing technology flows within joint ventures requires careful structuring. Partners must share sufficient information for effective collaboration while protecting proprietary knowledge outside the partnership's scope. Legal agreements define what each partner contributes and receives. Operational arrangements control information access and communication channels. These structures enable productive collaboration while managing competitive tensions.

Ownership and licensing of joint venture outputs present complex negotiations. Joint ownership of resulting intellectual property seems intuitively fair but creates practical complications when partners want to exploit innovations differently. Exclusive licensing to one partner may provide cleaner rights at the cost of the other's access. Creative solutions such as field-of-use divisions, geographic allocations, or sequential exclusive periods attempt to balance competing interests.

Manufacturing Partnerships

Manufacturing partnerships transfer production technology and capability between organizations. Foundry relationships, in which semiconductor design companies contract with specialized manufacturers, represent the industry's most developed form of manufacturing partnership. Contract manufacturing relationships in consumer electronics similarly involve substantial technology transfer.

The fabless-foundry model has transformed semiconductor industry structure. Design companies such as Qualcomm, Nvidia, and AMD focus on chip design while TSMC, Samsung Foundry, and other foundries handle manufacturing. This model requires extensive technology transfer from foundries to their customers regarding available processes, design rules, and manufacturing capabilities. The resulting specialization has enabled both design and manufacturing advances that integrated companies might not have achieved.

Technology transfer in manufacturing partnerships flows in multiple directions. Foundries provide customers with process technology information enabling effective designs. Customers provide foundries with market feedback driving process development priorities. Manufacturing experience generates know-how that foundries apply across their customer base. These multidirectional flows create complex intellectual property situations requiring careful management.

Quality control and process monitoring involve ongoing technology transfer. Customers receive detailed information about manufacturing parameters and yields to optimize their designs. Foundries gain insights from customers' performance requirements and failure analyses. This continuous exchange of technical information strengthens both parties' capabilities while creating dependencies and potential vulnerabilities.

Strategic Technology Alliances

Strategic alliances enable technology cooperation without the formal structures of joint ventures. Alliance partners agree to collaborate in defined areas while maintaining complete independence in others. These flexible arrangements suit situations where full joint ventures would be excessive or where competitive sensitivities require limited engagement.

Technology alliances in electronics often focus on ecosystem development. Platform companies form alliances with complementary technology providers to strengthen their platforms' capabilities and attractiveness. Intel's alliances with software developers have promoted technologies favorable to Intel's processors. ARM's partnerships with semiconductor manufacturers have extended the reach of ARM processor designs.

Research alliances enable pre-competitive collaboration on fundamental challenges. University-industry partnerships combine academic research capabilities with industrial application orientation. Multi-company research consortia address common challenges that would be inefficient for each company to pursue independently. These arrangements accelerate progress on foundational technologies while preserving competition in applications and products.

Technology Transfer Offices

University technology transfer offices (TTOs) manage the commercialization of academic inventions. These offices evaluate invention disclosures from faculty researchers, decide which to patent, market technologies to potential licensees, negotiate licensing agreements, and distribute royalty income. The professionalization of these functions has substantially increased university technology transfer activity.

The invention disclosure process captures potentially valuable innovations. Faculty and researchers report inventions to TTOs, which evaluate commercial potential, patentability, and fit with institutional priorities. TTOs decide whether to invest in patent protection, a significant commitment given filing, prosecution, and maintenance costs. Selected inventions proceed to patenting and marketing while others may be released to inventors or remain unpursued.

Marketing university technologies involves identifying potential licensees and communicating technology value. TTOs develop relationships with industry sectors relevant to their institutions' research strengths. They attend industry conferences, respond to company inquiries, and proactively approach potential licensees. Successful marketing requires both technical understanding of the innovations and commercial insight regarding potential applications.

Licensing negotiations balance university and industry interests. Universities seek fair returns on research investments and assurance that technologies will be developed for societal benefit. Companies seek terms enabling profitable commercialization given development risks and costs. Negotiations address royalty rates, exclusivity, development commitments, sublicensing rights, and numerous other terms that can significantly affect commercial outcomes.

Sponsored Research

Sponsored research agreements provide industry funding for university research in exchange for technology access rights. Companies support research aligned with their interests while gaining early visibility into resulting innovations. Universities receive research funding supplementing government and philanthropic sources. These arrangements create ongoing relationships that facilitate technology transfer beyond formal agreement terms.

Intellectual property provisions in sponsored research agreements generate substantial negotiation. Companies prefer rights to commercialize resulting inventions, while universities seek to preserve academic freedom and retain rights for educational and research uses. Compromise positions typically grant sponsors options or first negotiation rights for licenses while preserving university ownership and academic use rights.

Industrial liaison programs provide structured frameworks for sponsored research relationships. Companies pay membership fees for access to faculty, students, and research results across broad areas. These programs reduce transaction costs compared to negotiating individual agreements while building relationships that facilitate more intensive collaboration when particular opportunities arise.

Research centers and institutes provide dedicated facilities for university-industry collaboration. Companies may fund center operations, place personnel at university facilities, and participate in research direction. These arrangements enable deeper collaboration than typical sponsored research while creating potential conflicts between academic and commercial interests that require careful management.

Startup Companies

University startups provide an alternative commercialization path for academic innovations. When technologies require substantial further development before commercial application, licensing to established companies may not be attractive. Startup companies, often founded by faculty inventors or their students, can pursue development paths that established companies would not prioritize.

University policies regarding faculty startups vary considerably. Some institutions actively encourage entrepreneurship, providing resources, reducing barriers, and even investing in startups. Others maintain more restrictive policies, concerned about conflicts of interest, time commitments, or impacts on academic culture. These policy choices significantly affect technology transfer through the startup channel.

Licensing arrangements for university startups present particular challenges. Startups typically lack capital for substantial upfront payments, pushing toward royalty-heavy structures. Universities may take equity positions in lieu of cash payments, aligning institutional interests with startup success. Exclusive licenses may be necessary to attract investment, but universities seek provisions enabling reassignment if startups fail to perform.

Venture capital plays a crucial role in university startup technology transfer. Early-stage investors provide capital for technology development, business building, and market entry. Their involvement validates technologies and management teams, facilitating subsequent funding rounds. The ecosystem connecting university innovation, startup formation, and venture investment has become a significant pathway for electronics technology commercialization.

National Laboratory Technology Transfer

National laboratories operated by government agencies develop technologies ranging from fundamental science to advanced applications. The United States' network of Department of Energy laboratories, including Lawrence Berkeley, Sandia, and Oak Ridge, among others, has generated numerous electronics-related innovations. Technology transfer mechanisms enable private companies to access and commercialize these publicly funded advances.

Cooperative Research and Development Agreements (CRADAs) enable joint research between national laboratories and private companies. Companies contribute funding and expertise while gaining access to laboratory facilities and personnel. Resulting intellectual property rights are allocated by agreement, typically providing companies with commercialization rights in defined fields. These arrangements have facilitated substantial technology transfer from laboratories to industry.

Patent licensing from national laboratories follows processes similar to university technology transfer. Laboratories evaluate inventions, pursue patent protection for promising innovations, and negotiate licenses with interested companies. However, government ownership and mission-oriented laboratory structures create differences from university contexts. Laboratories may prioritize technology transfer that advances governmental missions beyond commercial value alone.

User facility programs provide another technology transfer channel. National laboratories operate expensive, specialized facilities available to outside researchers and companies on a fee or merit basis. Users gain access to capabilities they could not economically maintain independently while the facilities' operation supports laboratory missions. The research conducted transfers knowledge to user organizations while generating publications that disseminate findings broadly.

Defense Technology Transfer

Defense research and development generates technologies with substantial commercial applications. The Department of Defense, through agencies including DARPA, has funded innovations that later transformed commercial electronics. Technologies including the internet, GPS, and numerous semiconductor advances emerged from defense-funded research. Mechanisms for transferring these technologies to commercial application have been important policy concerns.

Dual-use technologies present particular opportunities and challenges. Technologies developed for military applications often have commercial potential, but transfer may be complicated by classification, export control, or concern about foreign access. Deliberate policies promoting dual-use technology development and commercial transfer have attempted to maximize return on defense research investments.

Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs direct defense research funding to small companies. These programs support development of technologies relevant to defense needs while building commercial capabilities in participating companies. The resulting technologies may serve both government and commercial markets, with intellectual property arrangements enabling private commercialization.

Defense contractor technology transfer presents complex situations. Contractors develop technologies under government contracts using varying combinations of government and private funding. Resulting intellectual property rights depend on contract terms, funding sources, and the nature of innovations. Commercial exploitation of contractor-developed technologies requires navigating these ownership complexities along with classification and export control requirements.

International Government Cooperation

International agreements facilitate government-to-government technology transfer and joint development. Allied nations collaborate on defense technologies through arrangements including NATO cooperative programs. Scientific cooperation agreements enable joint research between national research agencies. These agreements transfer technology while managing concerns about security and competitive implications.

Foreign military sales involve substantial technology transfer. When nations purchase military systems from foreign suppliers, the transactions often include technical data packages, training, and support arrangements that transfer knowledge to purchasing governments. Offset agreements may require technology transfer or local production as conditions of major purchases, further extending knowledge flows.

Development assistance programs transfer technology to developing nations. Aid programs may include technology components intended to build recipient nation capabilities. The appropriateness and effectiveness of such transfers has been debated, with some arguing that transferred technologies may not suit recipient contexts and that building indigenous innovation capacity deserves greater emphasis.

Standards Development Organizations

Standards development organizations (SDOs) convene industry participants to develop common technical specifications. Organizations including IEEE, ETSI, and ISO address different technology areas and geographic scopes. Participants contribute technical proposals, negotiate solutions, and commit to supporting adopted standards. This process transfers technology knowledge among participants while creating published standards accessible to all.

The standards development process itself involves technology transfer. Participants share technical information in proposals and discussions. Solutions incorporate elements from multiple contributors, combining innovations into coherent standards. Even unsuccessful proposals educate other participants about technical possibilities and constraints. This collective learning advances industry knowledge beyond what any single participant contributes.

Intellectual property policies govern how patents relate to standards. Most SDOs require participants to disclose patents relevant to standards under development. Policies typically require that essential patents be licensed on Fair, Reasonable, and Non-Discriminatory (FRAND) terms. These requirements ensure that standards adopters can access necessary patents while preserving patent holders' rights to reasonable compensation.

The economics of standards participation create interesting technology transfer dynamics. Companies invest in standards participation to influence technical directions favorable to their capabilities. They share innovations that may benefit competitors to enable larger market development. The resulting standards represent collective technology that participants access through their involvement in development processes.

Standard Essential Patents

Patents essential to implementing standards create unique technology transfer situations. Implementers cannot avoid using standard essential patents (SEPs) if they wish to comply with standards. This creates potential for patent holders to extract excessive royalties from locked-in implementers. FRAND commitments attempt to limit this potential while preserving incentives for innovation.

Defining FRAND terms has generated substantial litigation and policy debate. What royalty rates are reasonable? What licensing terms are non-discriminatory? Courts in multiple jurisdictions have addressed these questions, reaching somewhat varying conclusions. The resulting jurisprudence provides guidance while leaving significant uncertainty that complicates licensing negotiations.

SEP licensing programs enable technology transfer from innovators to implementers. Major patent holders establish licensing programs offering access to their SEP portfolios. Rates, terms, and scope vary among programs. Licensees gain freedom to implement standards while patent holders receive compensation for their contributions. These programs represent routinized technology transfer mechanisms that enable standards-based markets to function.

Patent assertion entities (sometimes called "patent trolls") have acquired SEPs from original developers and pursued aggressive licensing campaigns. Critics argue these entities extract value without contributing to innovation or standards development. Defenders suggest they provide liquidity for inventors and enforce legitimate intellectual property rights. The debate reflects broader tensions regarding technology transfer through patent licensing.

Patent Pools

Patent pools aggregate multiple patent holders' intellectual property under unified licensing programs. Pools reduce transaction costs for licensees who would otherwise need to negotiate with numerous individual patent holders. They also provide mechanisms for distributing royalty income among contributing patent holders according to predetermined formulas.

The DVD patent pools illustrate the model's operation. Essential patents for DVD technology were held by numerous companies including Philips, Sony, Pioneer, and others. Pools including DVD6C and 3C aggregated these patents under single licenses. Manufacturers could obtain all necessary patent rights through pool licenses rather than negotiating dozens of individual agreements.

Pool formation involves substantial negotiation among potential contributors. Determining which patents to include, how to price licenses, and how to allocate royalties among contributors all require agreement. Antitrust concerns constrain pool design, particularly regarding inclusion of non-essential patents or exclusion of competitors. Successful pools balance efficiency gains against these constraints.

Technology transfer through pools operates at both licensing and participation levels. Licensees receive rights to implement technologies covered by pooled patents. Participating companies gain visibility into each other's patent portfolios and technical approaches through pool operation. These mechanisms have facilitated technology diffusion for numerous electronics standards.

Bilateral Cross-Licenses

Bilateral cross-license agreements grant each party rights to use the other's patents. Companies with large patent portfolios find mutual benefit in avoiding the transaction costs and uncertainty of patent-by-patent licensing. Cross-licenses also reduce litigation risk by removing patent infringement claims between parties as competitive weapons.

Cross-license scope varies depending on party needs and portfolio characteristics. Broad cross-licenses cover all patents in defined fields, providing maximum freedom to operate. Narrow cross-licenses address specific product areas or known patent conflicts. Capture provisions may extend licenses to future patents, ensuring continued coverage as portfolios evolve.

Balancing payments compensate for portfolio value differences when parties' patents are not equivalently valuable. The party with the more valuable portfolio receives payments reflecting the differential. Determining these values involves complex analysis of portfolio strength, technical relevance, and potential damages in hypothetical litigation. Negotiations over balancing payments can be contentious given the stakes involved.

Cross-licensing facilitates technology transfer beyond the literal patent rights exchanged. Access to each other's patents enables companies to study patented innovations without infringement concern. The relationship created by cross-licensing may facilitate broader technology discussions and collaboration. These indirect effects can be as valuable as the formal patent rights exchanged.

Industry Cross-Licensing Patterns

The semiconductor industry has developed extensive cross-licensing networks. Major companies including Intel, Samsung, TSMC, and others maintain cross-licenses with each other and numerous smaller players. This web of agreements enables the industry to function despite the enormous number of patents potentially covering any given product.

New entrants face challenges accessing established cross-licensing networks. Without substantial patent portfolios, they cannot offer attractive exchanges to established players. Litigation or licensing on cash terms may be necessary to establish positions enabling future cross-licensing. This dynamic advantages established companies while creating barriers for newcomers.

Patent acquisition strategies often aim to strengthen cross-licensing positions. Companies acquire patents to fill portfolio gaps, establish positions in emerging technology areas, or gain leverage for licensing negotiations. The value of acquired patents often lies more in their contribution to cross-licensing than in their standalone licensing potential.

Open-Source Software

Open-source software has transformed electronics software development. Linux operating systems run everything from embedded devices to supercomputers. Android, based on Linux, powers most smartphones. Open-source tools, libraries, and frameworks underpin most modern software development. This massive technology transfer has occurred without traditional licensing compensation.

Open-source development models enable global collaboration. Contributors from companies, universities, and independent developers improve shared codebases. Version control systems track contributions and enable coordination. Governance structures, ranging from benevolent dictators to formal foundations, manage project direction. These mechanisms enable effective development despite distributed participation.

Companies contribute to open-source projects for various strategic reasons. Commoditizing software layers that might otherwise require licensing payments reduces costs. Improving shared infrastructure benefits all participants while spreading development costs. Establishing influence over important projects provides competitive advantages. Contributing developers build reputation and relationships valuable for recruiting. These motivations sustain substantial corporate investment in open-source development.

Business models around open-source software have evolved substantially. While software itself is freely available, companies generate revenue from support services, custom development, hosted versions, or proprietary extensions. The Red Hat model of enterprise support for open-source software demonstrated commercial viability. Cloud providers offer open-source software as managed services, generating controversy about their contributions back to projects.

Open-Source Hardware

Open-source approaches have extended to hardware design. The RISC-V instruction set architecture provides an open alternative to proprietary processor architectures. OpenPOWER makes IBM's Power architecture available for licensing. Various open-source development boards and reference designs enable hardware development without proprietary constraints.

RISC-V represents the most significant open hardware initiative in electronics. Developed initially at UC Berkeley, the RISC-V instruction set is freely available without licensing fees. Companies can implement RISC-V processors without paying the royalties that ARM or other architectures require. This has attracted substantial industry interest, with major companies including Google, Nvidia, Western Digital, and numerous startups adopting RISC-V for various applications.

Open hardware faces different challenges than open software. Hardware manufacturing requires substantial capital investment that software development does not. Physical production involves supply chains, quality control, and logistics beyond software distribution. These differences limit how directly open software models translate to hardware. Nevertheless, open approaches have gained traction in design and specification while manufacturing remains conventionally organized.

Open Standards and Data

Open approaches extend beyond software and hardware to standards and data. Open standards, developed through transparent processes and freely implementable, enable interoperability without proprietary constraints. Open data initiatives make research results, manufacturing parameters, and other technical information freely available.

The relationship between open standards and open-source implementations creates powerful technology transfer mechanisms. When both the standard and its implementation are openly available, barriers to technology adoption drop dramatically. This combination has enabled rapid diffusion of technologies including web standards, networking protocols, and data formats.

Transaction Cost Barriers

Negotiating technology transfer agreements involves substantial transaction costs. Identifying potential licensors and licensees, evaluating technology fit, negotiating terms, and documenting agreements all consume time and resources. These costs can exceed the value of transferred technology, particularly for smaller transactions, preventing potentially beneficial transfers.

Information asymmetries compound transaction costs. Technology owners know more about their innovations than potential acquirers. Acquirers know more about their application contexts and capabilities than technology owners. Overcoming these asymmetries requires disclosure that may itself transfer value or reveal competitive information. These dynamics complicate negotiations and can prevent agreement even when deals would benefit both parties.

Standardized licensing approaches reduce transaction costs for routine transfers. Patent pools, open-source licenses, and established licensing programs enable technology transfer without case-by-case negotiation. However, these approaches may not suit all situations, leaving transaction costs as barriers to non-standard transfers.

Valuation Difficulties

Determining appropriate compensation for technology transfer presents persistent challenges. Technology value depends on future applications, market developments, and competitive dynamics that are uncertain at transfer time. Parties' different information, expectations, and risk preferences lead to differing valuations that can prevent agreement.

Various valuation approaches address these challenges with different strengths and limitations. Cost-based methods consider development investments but may not reflect market value. Market-based methods compare to similar transactions but comparable deals may not exist. Income-based methods project future revenue but require uncertain assumptions. Combining methods provides perspective while not eliminating fundamental uncertainty.

Contingent payment structures can bridge valuation gaps. Royalties tied to commercial outcomes share risk between licensors and licensees. Milestone payments compensate at defined development stages. Equity arrangements align interests around venture success. These structures enable agreements when parties cannot agree on fixed valuations.

Enforcement Challenges

Technology transfer agreements require effective enforcement to function properly. Monitoring compliance, detecting violations, and pursuing remedies all present challenges. These enforcement difficulties reduce the reliability of technology transfer arrangements and affect parties' willingness to enter them.

Geographic scope creates particular enforcement challenges. Technology transferred to foreign jurisdictions may be difficult to monitor or protect. Legal systems vary in intellectual property enforcement effectiveness. International litigation is expensive and outcomes uncertain. These factors affect technology owners' willingness to transfer to certain jurisdictions.

Evolving technologies create ongoing enforcement challenges. Agreements drafted for current technology may not address future developments. Defining covered products becomes difficult as technologies advance. Audit rights and reporting requirements help but cannot fully address dynamic technology environments.

Digital Transformation of Transfer Mechanisms

Digital technologies are transforming how technology transfer transactions occur. Online platforms match technology seekers with providers. Smart contracts could automate licensing terms execution. Blockchain systems might provide transparent tracking of technology provenance and usage. These technologies could reduce transaction costs and improve transfer efficiency.

Policy Evolution

Government policies affecting technology transfer continue to evolve. Export controls restrict certain transfers to specified destinations. Foreign investment reviews affect technology acquisition through corporate transactions. Competition policy addresses patent licensing practices. These policies shape the environment within which legal technology transfer operates.

Balancing innovation incentives with technology access remains a central policy challenge. Strong intellectual property protection provides incentives for innovation investment but may restrict technology diffusion. Compulsory licensing, patent pools, and open approaches can improve access while potentially reducing innovation incentives. Finding optimal balances for different technologies and contexts continues to engage policymakers.
