Travelers Property Casualty Co. of America v. KLA-Tencor Corp.Annotate this Case
Travelers won summary judgment in this duty-to-defend insurance dispute with its insured, KLA. The superior court concluded that the language of the commercial liability insurance policies, which covered claims for “malicious prosecution,” could not have created an objectively reasonable expectation that Travelers would defend a “Walker Process claim” against KLA. The Walker Process claim that KLA tendered to Travelers alleged that KLA had fraudulently procured a patent and used that patent to attempt to monopolize the market for a product. KLA argued that it was objectively reasonable for it to expect the “malicious prosecution” coverage in its policies to extend to this Walker Process claim. The court of appeal affirmed. Coverage language is construed as of the time of issuance of the policy, so the construction of that language cannot depend on the precise allegations made in a subsequent complaint. The history of prior litigation between the parties did not change the basis for this claim into one for malicious prosecution because there were no allegations of any legal proceedings involving the patent.
