Judge Saris denied defendant NetApp’s motion for leave to amend and supplement its invalidity contentions for failure to demonstrate good cause as required by the local rules. NetApp, who was sued separately from Lenovo and EMC but whose case was joined, failed to connect its proposed amendment to the claim construction ruling, and waited a year between discovering the new prior art and seeking to amend. Given this, and that fact discovery is now complete and expert disclosures are imminently due, Judge Saris determined that the case “is aging and needs resolution.”
