  • Obtained dismissal of claims against insurer for alleged breach of the duty to settle; convinced court that, under Illinois law, insurer could not be liable for an excess judgment where the underlying claimant made no settlement demand within policy limits and could not establish a substantial probability of damages in excess of limits.
  • Persuaded Illinois appellate court to affirm ruling that insurer client had no duty to defend or indemnify general contractor for construction defects caused by subcontractors.
  • Obtained dismissal of fraud claims brought under Michigan law against insurer over alleged misrepresention to claimant that insurer would not contribute to the settlement of the underlying claims.
  • Evaluated and litigated coverage for insured video-game distributor's alleged infringement of plaintiff developer's intellectual property rights under Nevada law, including whether breach of contract exclusion applied to infringement of trade dress and copyrights that the claimant licensed to insured.
  • Intervened in underlying North Carolina lawsuit to seek allocation of intellectual property damages between potentially-covered and non-covered where insured allegedly infringed upon the claimant's medical product-related trade dress, trademarks, and patents.
  • Litigated whether, under Florida law, claims arising out of theft of laptops containing confidential health information implicated "personal and advertising injury" coverage for underlying settlement, arising out of the offense of oral or written publication of material violating a person's right to privacy, or "property damage" coverage due to loss of use of tangible property.
  • Established precedent in Seventh Circuit by securing dismissal of case brought by an ERISA plan on the basis that ERISA § 502(a)(3) precludes a plan from seeking monetary recovery that is not from a specifically identified account or fund. The court also recognized that federal courts lack subject matter jurisdiction to declare insurers owe coverage for unknown claims.
