SEOUL, SOUTH KOREA - NessCap Co. Ltd., a privately held company recognized as a global leader in ultracapacitor technology, product development, sales and manufacturing has filed a patent infringement lawsuit against Maxwell Technologies, (Nasdaq: MXWL) a San Diego, California based ultracapacitor manufacturer. The lawsuit alleges that Maxwell’s products, including the D cell product line of Boostcap® ultracapacitors, infringe NessCap’s patented intellectual property. NessCap filed the lawsuit in the United States District Court for the District of Delaware in Wilmington, Delaware. NessCap is represented in the lawsuit by Edwards Angell Palmer & Dodge LLP.

“NessCap has invested significant capital, resource and effort in developing our own proprietary and patented technology and we will not allow Maxwell to infringe” said Dr. Sunwook Kim, NessCap’s founder and chairman of the board.

Dr. Kim further observed: “for whatever reason, after our merger discussions ended abruptly, Maxwell started the legal battle by filing a lawsuit against us for infringement in San Diego, which we will demonstrate has absolutely no merit. We and our legal team have conducted an extensive review of our patent estate and we have determined that NessCap ultracapacitors, which Maxwell accuses of infringement, are protected by NessCap patents that predate the Maxwell patents at issue in the San Diego lawsuit. We are convinced that we have a very strong position.”
