Trevor Day assists clients in securing global utility and design patent protection in the mechanical and electro-mechanical arts and in materials science. Trevor drafts and prosecutes utility and design patent applications before the US Patent and Trademark Office. He also evaluates new inventions to formulate comprehensive patent drafting and filing strategies both in the US and abroad. Trevor directs foreign patent counsel around the world to secure international patent protection, and assists clients with freedom-to-operate analysis and search, patentability studies, patent validity analysis, and diligence. 

Trevor assists clients in both academia and industry, including clients ranging from early-stage start-ups to globally recognized academic institutions and corporations. He works with a wide range of technologies, including internet-of-things (IoT) devices, consumer products, sports equipment, medical devices, robotics, autonomous systems, vehicle systems and control, marine systems, electrical connectors, micro-electromechanical systems (MEMS), battery systems, and more. Trevor also regularly works with cross-disciplinary clients having inventions in the areas of software, materials, and chemistry in addition to the mechanical arts. 

Trevor always seeks to build relationships with clients to understand their needs and intellectual property goals. He often works directly with client engineers to provide an understanding of the patent system and to create a culture supporting and enhancing intellectual property protection. Trevor also ensures that patent strategies target efficiency aligning with client goals and budget. 

Prior to joining Wolf Greenfield, Trevor was a Mechanical Engineering Intern at Atlas Devices in Cambridge, MA. There, he designed and deployed a productivity management system to manage production of APA-5 Rope Ascenders, created and implemented a factory sensor mesh network system for data aggregation, and assembled, tested, and repaired equipment for use in maritime and other harsh environments. As an undergraduate at MIT, Trevor was a researcher in the MIT Stochastic Analysis and Nonlinear Dynamics Laboratory, where he developed a risk model of an oceangoing vessel to compute internal stresses and moments from ocean waves using a non-linear model with extreme events.


  • Assisted an early-stage start-up robotics company in building a patent portfolio resulting in an acquisition.
  • Assisted a consumer products start-up in securing patent protection for a product appearing on Shark Tank and resulting in a successful investment.
