Representative Experience

  • Defended a large manufacturing company against breach of contract and consumer fraud claims in a litigation in which the plaintiff sought $20M in damages. The matter was settled for a small fraction of the damages sought by the plaintiff.
  • Successfully defended an insurer against claims that a shopping mall was entitled to insurance coverage under the policy the insurer issued to a tenant. The court granted summary judgment in favor of the insurer finding that it did not owe coverage to the owner of the shopping mall for an underlying liability claim.
  • Represented an insurer in litigation in which a fortune 100 company was seeking over $10M in insurance coverage from the insurer. After extensive discovery, a settlement favorable to the insurer was reached.
  • Represented a family owned business seeking to bar two former employees from using a trade name that infringed upon its trade name. After a two week arbitration, the arbitration panel found in favor of the client and barred the former employees from using the trade name at issue.
  • Represented a large privately owned company in litigation in which it asserted claims of conversion and unjust enrichment against a fortune 500 company arising out of equipment leasing agreements between the parties. Prior to the trial, the parties reached a settlement on terms advantageous to the client.
  • Represented a privately held company in a shareholder dispute with a former employee and shareholder.

Search Tips

Our Web site's search function employs a variety of techniques to help you make the most of your queries. In this tips section we use square brackets [ ] to signal queries, so [antitrust and litigation] is one query, while [antitrust] and [litigation] are two.

  • Exact phrases: Eliminate unnecessary search results by surrounding your search phrase with quotation marks. Placing ["project finance"] in quotes will return specific results and discard additional results that simply have the words "project" and "finance" peppered on a page.
  • Wildcard symbol: If you're not exactly sure how a piece of information you want is phrased, use the following symbol (*) as a word root expander. A search for [child*] will find not only "child," but also results with words like "children" and "childhood."
