  • Successfully prosecuted a patent infringement case through trial and appeal on behalf of industry-leading Quickie Manufacturing Corporation.

  • Represented a leading supplier of gifts and novelties in an unfair competition and breach of license dispute, including oral hearing on a motion for preliminary injunction.

  • Represented a leading consumer products manufacturer in multiple unfair competition, Lanham Act and copyright cases against competitors involving product and product packaging claims and misrepresentations, colors, trademarks and trade dress. The cases settled favorably, resulting in changes to defendants' products and packaging.

On the eve of trial, the case settled following entry of summary judgment in favor of the defendants on the copyright infringement claims.
  • Defended a leading manufacturer of animal litter in a patent infringement case. With the plaintiff having waited years to bring suit after first contacting our client, the defense developed compelling evidence of noninfringement and invalidity, in addition to laches and estoppel. The case settled following the deposition of the inventor and defendant's submission of expert reports.
  • Prosecuted a copyright infringement action relating to the misappropriation and copying of technical drawings. While the case was on appeal to the Seventh Circuit following a protracted bench trial, it settled on favorable terms.
  • Successfully defended Tensor Corporation in Rule to Show Cause proceedings. Tensor Corporation purchased out of bankruptcy the assets of Dev Corporation, which was forced out of business following the entry of an injunction against it in a case brought by Rockwell International. Rockwell later filed a Rule to Show Cause motion against Tensor, accusing it of violating the permanent injunction previously entered against Dev. After convincing the District Court to dismiss the proceedings on privity and timing grounds, and following two appeals to the Seventh Circuit, the case settled before the court ever heard argument on the merits. 
  • Regularly serves as outside counsel for all intellectual property matters for public and private corporations, including prosecution of patents, trademarks and copyrights; maintenance of intellectual property portfolios; advertising and marketing clearance; and pre-litigation counseling, strategy and clearance.
