  • Successfully represented TouchCom Technologies, Inc., in an intellectual property license dispute against Dresser, Inc., before a three-member AAA arbitration panel. After a week-long hearing, the panel ruled in TouchCom's favor. The award paved the way to a multimillion-dollar settlement of TouchCom's pending patent infringement case against an industry-leading manufacturer of gasoline dispensing products.
  • Successfully prosecuted a patent infringement case through trial and appeal on behalf of industry-leading Quickie Manufacturing Corporation. The Federal Circuit affirmed the District Court's infringement finding. In its memorandum opinion, the District Court specifically noted that John had repeatedly impeached Libman's primary witness, its chief executive officer, and made a finding that the witness was not credible. Libman Company v. Quickie Manufacturing Corporation, 74 Fed. Appx. 900, 2003 WL 22025068 (Fed. Cir. 2003).
  • Successfully defended Ondeo Nalco Company (declaratory judgment plaintiff) in a patent infringement case in the District of Delaware involving a chemical additive and method for manufacturing paper. After opening statements and during examination of Eka's first expert witness during jury trial, Ondeo Nalco moved for a mistrial, arguing that opposing counsel had improperly elicited testimony in violation of prior rulings by the court. The court granted Ondeo Nalco's request for a mistrial and the case favorably settled shortly thereafter.
  • Successfully defended Northfield Corporation in a patent infringement case through trial and appeal. The case was bet-the-company for Northfield, as it threatened its primary product line. After a jury verdict of noninfringement in favor of Northfield, the case settled following oral argument before the Federal Circuit on Northfield's appeal of the District Court's denial of attorney's fees. 
  • 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. In combating the wide range of defenses asserted by defendants, John was able to convince the District Court that advertising under the Lanham Act included oral statements made to attendees at trade shows.
  • 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. 
  • Defended Samsung Corporation in a patent infringement case filed against several leading manufacturers of cellular phones. The accused devices were cellular camera phones. After moving the court to bifurcate damages and liability, Samsung was able to settle the case.
  • Successfully defended copyright, trade secret and breach of contract claims against a newly formed software company composed of several former employees of the plaintiff company, including the author and creator of the plaintiffs' competitive auditing software. In an attempt to exploit the limited resources of a nascent company, the plaintiffs turned to litigation in an effort to put the new company out of business. 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. Provides ongoing counsel to numerous clients in intellectual property due diligence matters and the creation and maintenance of outside inventor programs.
