and the two companies jointly sued Quickturn over an alleged patent infringement. Amr Mohsen, CEO of Aptix, forged and tampered with legal evidence and was subsequently charged with conspiracy, perjury, and obstruction of justice. Mohsen was arrested after violating his bail agreement by attempting to flee the country. While in jail, Mohsen plotted to intimidate witnesses and kill the federal judge presiding over his case. Mohsen was further charged with attempting to delay a federal trial by feigning incompetency. Due to the overwhelming misconduct, the judge ruled the lawsuit as unenforceable and Mohsen was sentenced to 17 years in prison. Mentor Graphics subsequently sued Aptix to recoup legal costs. Cadence also sued Mentor Graphics and Aptix to recover legal costs. *Berkeley Design Automation In 2013, Cadence sued Berkeley Design Automation (BDA) for circumvention of a license scheme to link its Analog FastSpice (AFS) simulator to Cadence's Analog Design Environment (Virtuoso ADE). The lawsuit was settled less than one year later with an undisclosed payment of BDA and a multi-year agreement to support interoperability of AFS with ADE through Cadence's official interface. BDA was bought by
