This is a non-precedential opinion from the United States Court of Appeals for the Federal Circuit affirming a district court's dismissal of a patent infringement lawsuit filed by Xiaohua Huang against Amazon. Huang alleged that Amazon infringed his patents on ternary content addressable memory technology through the use of EEPROM chips in various products. The district court dismissed Huang's complaint and denied his motion to amend, finding his allegations too vague and conclusory to provide Amazon with adequate notice of the infringement claims. The appeals court agreed, concluding that Huang failed to sufficiently link specific accused products to the allegedly infringing chips, even after multiple attempts to amend his complaint. The court upheld the district court's decision based on established Ninth Circuit precedent regarding pleading requirements and motions for leave to amend.
