CAPCOM requested damages that totaled 983,231,115 yen (about US$9.12 million) for KOEI Tecmo’s infringement of Patents A and B. The Intellectual Property High Court ruled on September 11, 2019 that only part of KOEI Tecmo’s relevant works infringed on Patent A, and therefore ordered KOEI Tecmo to pay only part of the amount that CAPCOM requested.
CAPCOM claimed KOEI Tecmo infringed on Patent No. 3350773 (Patent A) with the Dynasty Warriors and Samurai Warriors game series, and Patent No. 3295771 (Patent B) with the Fatal Frame game series.
CAPCOM argued that KOEI Tecmo infringed on Patent A with “new content acquired through using a previous game and new software” and on Patent B with “a controller-vibrating feature when enemies are nearby.”
The Osaka District Court ruled on December 14, 2017 that KOEI Tecmo infringed on only Patent B, and ordered the company to pay 5.17 million yen (about US$48,000) in damages and legal fees.
