Tomoki Hattori is a Technical Advisor in the Electrical and Mechanical Practice Group, where he focuses on patent application drafting, bringing nearly two decades of experience in software engineering, cloud infrastructure, and systems design to support patent prosecution and IP strategy. His technical background spans a wide range of domains, including enterprise software architecture, cloud-native platforms (OCI, AWS, Azure), cybersecurity, embedded systems, and AI-driven data applications.

Prior to joining the firm, Mr. Hattori served as a Principal Technical Support Engineer at Oracle, where he advised enterprise clients across the U.S. and Japan on complex issues involving Oracle Exadata, RAC clusters, and OCI infrastructure. In addition to troubleshooting high-availability environments, he contributed to Oracle's AI innovation efforts by developing Proof of Concept (PoC) for Retrieval-Augmented Generation (RAG). The project utilized Java, Spring Boot, and Spring AI, integrating a locally hosted Llama 3 LLM via Ollama with Oracle 23ai vector tables to enable secure, real-time enterprise question answering using private structured and unstructured data. This solution showcased scalable, AI-driven support systems for enterprise customers and highlighted his ability to bridge infrastructure with next-generation AI.

He previously worked at Amazon AWS as a Systems Development Engineer, where he built global CI/CD automation tools and software distribution agents for engineering teams across regions. At General Motors, he led full-stack modernization projects, architecting microservices using Spring Boot and Angular, and implementing secure authentication using Azure Active Directory and OAuth2.0.

Educated in both the United States and Japan, Tomoki holds a Master of Science in Computer Science from Georgia Institute of Technology and a Bachelor of Science in Computer Science from Iowa State University. He is a named inventor on 13 U.S. patents, with innovations spanning secure printing, certificate management, and distributed systems. Fluent in Japanese, Tomoki leverages his technical depth and bilingual communication skills to support patent attorneys in translating complex technologies into clear, defensible intellectual property.
