Marathon Patent Group Inc. (MARA), the patent licensing company that hired IP Navigation Group owner and founder Erich Spangenberg to head its enforcement efforts in Asia and Europe, said its wholly owned subsidiary Traverse Technologies has acquired a portfolio of approximately 40 worldwide patents from privately held CPT IP Holdings LLC.

Los Angeles-based Marathon didn’t disclose the terms of the transaction. Officials from Marathon couldn’t be reached immediately for comment. Spangenberg is Marathon's largest shareholder with about a 16.3% stake in the company.

Marathon’s Traverse Technologies portfolio relates to battery anodes and cathodes that utilize bulk, thin film, and nanostructure fabrication techniques. It enables exceptional battery performance for large-scale applications such as electric vehicles and consumer electronics, and also allows for integration into microsystems to enhance overall functionality. The technology utilizes both nano-materials and nano-structures to significantly improve battery performance, and covers all the major global economies including China, Germany, Japan, Korea, the United Kingdom and the United States.

“Our portfolio of assets and opportunities continues to expand at a pace never previously seen in our corporate history,” CEO Doug Croxall said in a statement. “This portfolio will further expand Marathon's patent licensing activity into Asia, while remaining active in both the United States as well as countries in Europe."

Marathon said its IP advisory unit Marathon Advisors S.a.r.l. will be leading the licensing and strategic transaction negotiations related to the acquired technology.

Marathon Advisors said in the statement that energy storage will be a key technology focus for Marathon going forward. The firm said it is working with some of the leading experts in the world and is seeking to find creative ways through pooling and other structures to partner with other leaders in the energy storage space.

In addition, the firm said it has already had a number of early conversations with potential licensing and strategic partners and hopes to expand the universe of companies and experts it is already working with.

CPT IP Holdings appears to be related to Catalyst Power Technologies, which is the applicant on a number of battery power storage patents invented by Ronald A. Rojeski who Marathon says is CEO of CPT IP Holdings.

Marathon said Rojeski is the lead inventor on the patents being acquired, and is a recognized thought leader in finding ways to incorporate high energy density materials, such as silicon, into energy storage devices. The results of this effort are batteries with enhanced power performance, improved safety, and reduced charging times.

"We invested heavily in the R&D that underlies these patents and solved a significant problem that enhances battery performance. I look forward to working with Marathon Advisors to encourage adoption of this technology and to work with other innovators to expand the Traverse technology offering," Rojeski said in a statement.

According to his profile on the LinkedIn professional networking site, Rojeski is based in the San Francisco Bay area. He lists his current experience as senior systems engineer for Nanonmetrics from May 2010 to present. He previously had been a senior systems engineer at Cymer, an ASML Company from July 2008 to April 2010, a consultant at Triple Ring Technologies from November 2007 to June 2008. He also previously worked as a senior systems engineer at Nanoconduction and KLA-Tencor.

He has a BSE in electrical engineering and an MSE in nuclear engineering from the University of Michigan.
