Inventor-controlled Kove IO, Inc. has won an infringement verdict in its litigation against Amazon. On April 10, an Illinois jury found that the company had infringed three distributed network storage patents through its Simple Storage System (S3) and DynamoDB products and awarded $525M in damages, though it also determined that this infringement had not been willful. Litigation leading up to that trial dealt in part with the impact of certain ex parte reexaminations (EPRs) against the asserted patents, after the district judge found that the patent owner had disclaimed certain subject matter through statements made in those proceedings.
