Daniel Spillman

Daniel counsels a wide range of clients in the mechanical arts in the United States and internationally. Leveraging his IP legal and in-house experience, Daniel Spillman builds trusting relationships with clients by providing creative strategies for IP asset generation and management in view of evolving economic challenges. Spillman believes the question to ask for any generated IP asset is “why?” prior to asking “how?”. Helping clients understand the purpose of an IP asset in view of the client’s technology and business strategy, the competition’s portfolio and products, the client’s IP budget, as well as other factors, will help drive the appropriate measures to how best to protect the client’s generated IP assets. 

Prior to joining Brinks, Daniel was Corporate IP Counsel at Caterpillar Inc. for over four years.  While there, he had responsibility for the global IP strategy, including patent portfolio and IP risk management for several multi-billion dollar divisions. His responsibilities included patent portfolio building and pruning, conducting idea capture sessions and patent review boards, drafting and negotiating IP and commercial agreements, and counseling clients about various IP conflict mitigation strategies, including clearance and development of noninfringement and invalidity positions. He supported Caterpillar’s power systems divisions, which innovated in areas of reciprocating power systems and components, diesel engines, engine control systems and methods, emissions control and after-treatment systems, heat exchangers for engine and machine cooling, and turbocharger technology. Daniel also supported machine components and systems divisions, which developed integrated technologies and solutions for CAT machines. Particularly, he managed the hydraulics and components patent portfolio, including technologies involving energy recovery and hybrid, implement, steering and ride control, hydrostatic transmissions, pumps and motors, valves, and cylinders, as well as technologies involving graphical user interfaces, joysticks, seats and suspensions, and cab structures.

Prior to Caterpillar, Daniel worked for Brinks where he focused on building patent portfolios for biomedical products involving a variety of medical devices, such as stent, stent-grafts, catheters, wire guides, and delivery devices.
