I have no idea how Lexmar's patents compare to the MMP.  Apparently there was no secrecy in revealing the $288 million settlement on this one.

 6.Lawsuits and others

The Group undertakes global business operation, and is involved in disputes, including lawsuits, and other legal procedures and is investigated by authorities. There will be also possibility of such a case in future. Due to differences in judicial systems and difficulties in predicting prospects in these procedures, it is difficult to rule out the possibility that the Group may be subject to an authoritative order requiring payment of an amount far exceeding normal expectations. Judgments unfavorable to the Group in these cases may impact on Group operations.
Lexar Media, Inc. (Lexar) filed suit against the Company and its U.S. subsidiary, Toshiba America Electronic Components, Inc., alleging misappropriation of NAND flash-related trade secrets and related misconduct. On September 15, 2006, the Company entered into agreements with Micron Technology, Inc. (Micron), the parent company of Lexar, under which the Company purchased certain of Micron's semiconductor technology patents and also licensed all the patents currently and previously owned by Lexar, in exchange for payments totaling US$288 million. At the same time, a settlement was concluded that dismissed all outstanding litigation and legal procedures between the Company, Toshiba America Electronic Components, Inc. and Lexar, all of which were related to patent infringement, trade secret misappropriation, and an investigation concerning prohibiting importation of the Company's NAND flash memories into the U.S. due to alleged patent infringement.
In January 2007, the European Commission adopted a decision that imposed fines on 19 companies, including the Company, for infringing EU Competition Law in the gas insulated switchgear market. The decision imposed a fine of 86.25 million euro (approximately 13.5 billion yen) on the Company, plus a fine of 4.65 million euro (approximately 0.73 billion yen) jointly and severally with Mitsubishi Electric Corporation. Following its own investigation, the Company contends that it has not found any infringement of EU Competition Law, and it is bringing an action to the European Court of First Instance seeking annulment of the European Commission's decision.
