Ling Cheung Hughes provides intellectual property legal services to clients ranging from budding startups to successful growth stage companies to multinational corporations to leading academic institutions. She prides herself on her ability to dig into the toughest technologies and at the same time appreciate their business relevance. Ling invests in her clients by taking time off the clock to learn about their businesses so she can craft creative legal solutions tailored to specific business goals. 

Ling has extensive technical training in formal verification, distributed computing, network security, and cryptography. Her graduate research focused on modeling and verification of randomized embedded system algorithms using techniques such as theorem proving and model checking.

Prior to joining Wolf Greenfield, Ling was a postdoctoral researcher at MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), where she developed a novel attribute-based encryption scheme that provides fine-grained access control for databases, multicast communication, and other data sharing applications. Her paper on the encryption scheme has been cited over 600 times. In addition, she built a mathematical framework for proving security of long term services such as signatures and timestamps. During her time at MIT, Ling also consulted for Lincoln Laboratory, where she developed a group key management protocol for military applications in high latency and low connectivity communication environments. 

These days, Ling enjoys serving clients with cutting edge technologies such as data analytics for web fraud detection, identity management using blockchains, static source code analysis for detecting security vulnerabilities, datacenter network management, hardware authentication for the Internet of Things (IoT), speech recognition and applications in virtual assistants, and machine learning for optimizing on-demand manufacturing of biologics. 

Ling is particularly skilled at developing and executing patent filing strategies. For example, she has regular successes with the US patent office’s fast track program, obtaining allowances within 6-9 months of filing. She interrogates inventors rigorously to tease out technical aspects of their inventions, allowing her to draft patent applications that clearly articulate those technical improvements and advantages, an important foundation for fending off subject matter eligibility (Alice) rejections. Ling also provides a full spectrum of other IP services, including due diligence, licensing, freedom-to-operate, post grant proceedings, and litigation. 

Ling strives to be not only an excellent lawyer for her clients, but also a responsive and dependable business partner. She is passionate about fostering innovation and immerses herself in the Boston entrepreneurial ecosystem, regularly teaching IP basics at VentureWell (formerly NCIIA) accelerator workshops, mentoring startup teams through the MIT Enterprise Forum and the MIT 100K competition, and attending angel investor meetings. Her goals are to give back to the community and at the same time to build experiences and connections that will allow her to better serve her clients.

  • Provided strategic counsel to multiple startup clients and built worldwide patent portfolios, contributing to successful funding rounds and/or exits.
  • Drafted and prosecuted patent applications related to software, e-commerce, networking technologies, hardware, medical devices, and consumer products. Recent examples include:
    • Real time data analytics for web fraud detection
    • Identity management using blockchains
    • Static source code analysis for detecting security vulnerabilities
    • Speech recognition and applications in virtual assistants
    • Machine learning for optimizing on-demand manufacturing of biologics
    • Datacenter network management
    • Network optimization for electronic news gathering
    • Interconnection systems for printed circuit boards
  • Analyzed patent portfolios for patentability, clearance, licensing, and/or due diligence purposes. 
  • Prepared non-infringement and invalidity opinions for major consumer electronics and semiconductor companies.
  • Served as lead technical associate in post-grant proceeding and district court litigation on healthcare IT patent, successfully defending against obviousness attack.
  • Served as lead technical associate in Section 337 (International Trade Commission) investigation on magnetic storage patents, obtaining favorable claim constructions.
  • Association for Computing Machinery (ACM)
  • IEEE Computer Society
  • Boston Patent Law Association

Ling is a member of Phi Beta Kappa and Tau Beta Pi. While in law school, she received the Legal Practice Skills Best Brief and Best Oral Advocate Awards, as well as the American Jurisprudence Award in Professional Responsibility. 

Ling was named to the 2016 and 2017 list of Massachusetts Rising Stars by Super Lawyers.
