Micron Tech., Inc. v. Rambus, Inc., 255 F.R.D. 135 (D. Del. 2009)
In this case arising from Micron’s alleged infringement of Rambus’ patents, a bench trial was held on the issue of Rambus’ alleged spoliation of relevant documents pursuant to a document retention policy it had recently implemented. The court ruled that Rambus had intentionally spoliated documents in bad faith. As a sanction, the court declared the patents in suit unenforceable against Micron.
