Narrative Opinion Summary
The case involves Creo Products Inc. filing a lawsuit against Dainippon Screen Manufacturing Co. Ltd. and its affiliates, alleging patent infringement, breach of contract, and misappropriation of trade secrets. The U.S. District Court for the Western District of Washington granted Dainippon summary judgment on the patent and contract claims and awarded attorney fees, which Creo appealed. The appeal focused on the enforceability of two agreements: a 1990 letter agreement and a 1991 formal contract. The district court found the 1990 agreement unenforceable due to an integration clause in the 1991 contract, a decision upheld by the appellate court. Furthermore, the appellate court agreed that prosecution history estoppel prevented the application of the doctrine of equivalents, affirming the summary judgment for Dainippon. Additionally, the court upheld the award of attorney fees under 35 U.S.C. § 285, rejecting Creo's arguments that it was not asserting certain claims. The exclusion of expert testimony on damages became moot with the affirmation of the summary judgment. The rulings ultimately favored Dainippon, leaving Creo without relief on its claims.
