Case examples

  • Versata Software Inc v SAP America Inc  AZA lawyers were called in a few months before trial and developed a previously untapped lost profits claim theory. On the eve of the trial, the court dismissed everything but the lost profits model that AZA developed. With AZA’s help, Versata won the nation’s second-largest patent verdict in 2011 at $391 million, according to Verdict Search. 
  • Rembrandt Wireless Technologies LP v Samsung Electronics Co Ltd – AZA beat the odds when it obtained a $15.7 million federal jury verdict in the Eastern District of Texas in a 2015 patent infringement case. Jurors deliberated only one hour to find that Korean electronics giant Samsung Electronics Co Ltd had infringed on two Rembrandt Wireless Technologies LP patents covering Bluetooth technology. The victory received widespread press coverage, including from technology-related publications that had bet the odds against AZA winning this case. 
  • AZA is overseeing potentially precedent-setting IP cases in the United States and Germany for the owner of six families of voice coding patents that are essential to the wideband speech audio coding standard for high-definition voice in mobile telephony known as adaptive multi-rate-wideband (commonly ‘AMR-WB’).
  • Sentinel Integrity Solutions, Inc v Mistras Group, Inc – AZA defended Mistras Group, Inc, a major non-destructive testing provider, against claims for trademark infringement and dilution brought by Sentinel Integrity Solutions Inc. Sentinel brought a claim for $8 million in damages. AZA not only won on the trademark infringement claim with the federal judge, but convinced the jury to agree to invalidate the trademark.
