Synqor, Inc. Artesyn Techs., Inc., No. 11-1191 (Fed. Cir. 2013)Annotate this Case
High-efficiency DC-DC power converter systems are used to power circuitry in large computer systems and telecommunication and data communication equipment. The patents at issue involve converters with separate “isolation” and “regulation” stages and improved prior art power converter systems that used integrated converters, each performing both isolation and regulation, to step the 48 volt input down to the voltage levels required to power logic circuitry. Large computer and communication systems use multiple voltage levels for different logic circuitry housed on a single load board, and the prior art systems required a separate isolating/regulating converter for each voltage level, which took up valuable space on the load board, which could otherwise accommodate more memory and other logic circuitry. The district court entered summary judgment of infringement and awarded $95 million in lost profits plus enhanced damages for post-trial infringement, finding that the “isolation” limitations of the patents appeared in defendants’ products. The Federal Circuit affirmed.
