Ryota is an extremely rare Japanese-English bilingual US patent attorney. Ryota can seamlessly work with both native-English and native-Japanese inventors to find the core concept in their inventions. Ryota’s diverse technical expertise, stemming from his academic background in mechanical engineering and electrical and computer engineering, combined with his extensive legal experience at a general practice law firm and an IP boutique law firm, uniquely enables him to address various technical and legal problems for clients. One of his clients includes a Japanese pharmaceutical company that highly appreciates his expertise in developing a strong patent portfolio in the US based on inventions made by Japanese inventors.

He also handled freedom-to-operate analysis in the field of medical devices, including endoscopes and ultrasound probes, as well as providing IP litigation support and IP due diligence support in M&A deals. Ryota was also an associate at Patterson & Sheridan, LLP, where he primarily handled patent procurement in the field of complex semiconductor device structures and functions and image forming devices. In Japan, Ryota started his career as an IP associate at Canon, Inc., where he obtained substantial IP insights through his patent portfolio development work for its R&D department, primarily in the fields of imaging (e.g., OLED and X-ray digital imaging), optics, and semiconductor manufacturing devices.
