Chad Landmon chairs Axinn's IP and FDA Practice Groups and focuses his practice on patent litigation and counseling and food and drug law, with an emphasis on pharmaceuticals, biologics and human tissue products. He maintains a particular focus on Paragraph IV patent litigation, having litigated dozens of cases for numerous pharmaceutical companies involving a wide variety of products, including on many blockbuster products. By coupling his patent litigation experience with his FDA expertise, Chad enables pharmaceutical clients to develop and execute on patent and FDA strategies to bring products to market in the most efficient and profitable manner. 

Chad's FDA matters involve petitioning FDA and litigating issues relating to the Hatch-Waxman Act, including marketing exclusivities, patent listing, certification and notification requirements, bioequivalence, labeling and other issues relevant to the FDA drug approval process. His active FDA litigation practice has enabled clients to maintain their exclusivity rights and obtain market entry. In fact, Chad led the efforts to obtain a court order that has been described as the fist time a court has ordered FDA to approve a product. 

With a practice that also includes matters involving the intersection of the antitrust and patent laws, such as issues arising from the settlement of patent and Hatch-Waxman exclusivity disputes, Chad frequently speaks and writes about issues relating to the Hatch-Waxman Act and litigation in the life sciences industry.

  • In what has been described as the first time a court has ever ordered FDA to approve a product, Axinn secured summary judgment on behalf of Watson Laboratories, Inc. in litigation against the U.S. Food and Drug Administration in the U.S. District Court for the District of Columbia. The case involved a dispute over the 180-day "first-to-file" marketing exclusivity for generic versions of the multi-billion dollar product Actos (pioglitazone hydrochloride).  The court's ruling includes an order that paved the way for the company to bring its generic diabetes drug to market.   
  • After trying the patent case, obtained a favorable settlement that will enable Actavis to bring its generic version of Shire's ADHD product Intuniv to market.  Through the course of the litigation and after conducting aggressive fact discovery, Shire dedicated its core method of use patent to the public, removing it from further dispute in the litigation. 
  • Obtained a favorable decision for our client, Alvogen, Inc. after intervening in an action against FDA by a competitor over generic versions of the antibiotic Vancocin. The competitor requested a preliminary injunction that would have forced Alvogen's generic version of Vancocin off the market.  Within less than a week, Axinn successfully moved to intervene, submitted opposition papers, and defeated the request for preliminary injunction, allowing Alvogen's version of Vancocin to remain on the market. 
  • Provided extensive counseling to a human tissue company developing platform technology using adult stem cells.  Such counseling has enabled the client to design around other's patents, secure its own patent protection and negotiate a license in a critical technology area at a fraction of the demanded royalty.  
  • Obtained a dismissal of a Lanham claim brought by Wyeth against Sun Pharmaceutical relating to the blockbuster drug Protonix.  The case involved allegations that Sun was engaged in false advertising in marketing its generic product.  The case was dismissed based upon an argument that the claims were preempted by FDA law. 
  • Successfully negotiated an extensive patent license and product distribution agreement relating to a blockbuster product.  Chad was brought in to negotiate the agreement on the eve of trial given the complexities of the patent, FDA and business issues.
