Today’s business disputes frequently involve, directly or indirectly, computer software and information technology. These disputes routinely turn on the performance of computer hardware and/or software, online transactions, traditional proprietary rights (including domain names and trademarks) and emerging rights in data.

Understanding the technology in IT and the environments in which it is developed, deployed and exploited can be critical to resolving such disputes successfully. Calfee’s experienced litigation, IT, intellectual property and commercial lawyers assist clients with their IT disputes throughout the mediation, arbitration or litigation process in state or federal courts.
