US-Japan Cross Border IP Litigation // Understanding US-Japan Cross-border Patent Opportunities and Risks – San Francisco

September 21, 2018 @ 12:00 pm - 1:30 pm

$20 – $30

Understanding US-Japan Cross-border Patent Opportunities and Risks, Ryoichi Mimura, Nagashima Ohno & Tsunematsu

September 21  12:00 to 1:30 | Dentons, One Market Plaza Spear Tower, 24th Floor San Francisco, CA 94105 Lunch (bento) will be served  

It may surprise some to hear that, on the basis of patent filings based on US-Japan collaboration, Japan is the Bay Area’s most significant innovation partner.  With that high level of collaboration comes a great deal of cross-border IP litigation between the US and Japan. To address this timely topic, Ryoichi Mimura of Nagashima Ohno & Tsunematsu, a Japanese attorney with extensive patent trial experience as a lawyer currently and formerly as a judge, will speak at Dentons about current issues in cross-border patent litigation.  

Please come hear Mr. Mimura’s presentation which will address recent Japanese Supreme court decisions on equivalents law in Japan, patent nullity defense, patent exhaustion in cases where products are distributed internationally, the jurisdiction of Japanese courts in foreign patent disputes and the possibility of enforcement by Japanese courts of American judgments that order compensation of vindictive damages.
