Three recent cases of note:

Versata v. SAP
Mr. Anaipakos  helped client Versata Software not only reach a $391 million patent infringement jury verdict using a new lost profits claim, but also uphold that win over years of high-powered appeals. Mr. Anaipakos was actively involved in the development of the winning lost profits model, and developing the arguments that resulted in the affirmation of the model on appeal.  Mr. Anaipakos was also in charge of settlement discussions for Versata, and the case settled for a confidential sum that was paid to Versata in September 2014. Read about the patent verdict here. See a news story on the final case here.

Rembrandt v. Samsung
Mr. Anaipakos beat the odds when he obtained a $15.7 million federal jury verdict in Texas in this patent infringement case. Jurors deliberated only one hour to find that Samsung Electronics infringed on two Rembrandt Bluetooth patents. Rembrandt, a business technology company, will likely receive royalty payments on all Samsung Bluetooth sales for the life of the patents. Rembrandt argued Samsung in its Galaxy S phones and other devices infringed on “enhanced data rate” inventions.  Mr. Anaipakos confronted the problem of representing a non-practicing entity by telling jurors exactly what these companies do. See a news story on the case here.

Saint Lawrence Communications v. Deutsche Telekom
Mr. Anaipakos is overseeing potentially precedent-setting cases against multiple defendants filed simultaneously in the U.S. and Germany for St. Lawrence Communications, a patent licensing company. St Lawrence owns six families of patents that are essential to the Adaptive Multi-Rate-Wideband (“AMR-WB”) standard.  In German cases against Deutsche Telekom, Vodafon and LG the injunctive relief sought and ordered for AZA’s client is “momentous” and is being watched closely by the media and the industry.  See an articles on the cases here, here and  here.
