Attorney Awards


A senior partner at Seeger Weiss LLP, Mr. Buchanan represents individual and corporate plaintiffs in state and federal courts throughout the country. His practice focuses on litigating and trying complex commercial and product liability matters.

Mr. Buchanan's docket involves a wide variety of cases, including pharmaceutical injury, product liability claims, trade secrets, commercial disputes, pension challenges, securities and investment fraud, and consumer claims. Though the scope of his cases is broad, they are usually large, national, high-stakes cases, generally destined for trial. By their nature, they are often centered in federal multi-district proceedings or analogous state coordinated proceedings, where Mr. Buchanan is often selected by his co-counsel or appointed by the courts to lead them as liaison counsel, lead counsel, or a member of plaintiffs' executive/steering committee.

Mr. Buchanan's scientific background is a ready asset featured in the technical and pharmaceutical cases in which he often focuses. He is likewise known for his extensive experience in the discovery and preservation of electronic information, and has served as a consultant in this capacity for many other law firms. He is frequently invited to speak to an array of audiences and conferences-directed to practicing plaintiffs' and defense attorneys, judges, students, and professional organizations-on issues concerning trial practice, discovery, and complex and products liability litigation.

Ill.), which resulted in a $140+ million verdict for a 49-year old Tennessee man who used AndroGel for two months and suffered a heart attack.

* In re National Football League Players' Concussion Injury Litig., MDL No. 2323 (E.D. Pa.). Appointed to the Plaintiffs' Executive Committee by the Hon. Anita Brody. Co-lead negotiations on behalf of plaintiffs in this highly visible and contentious multidistrict litigation on behalf of retired players against the National Football League. Helped negotiate settlement resulting in substantial monetary awards for injured players (up to $5 million per player for the most severe injuries) and a medical testing program. The settlement, valued at more than $1 billion, was overwhelmingly supported by the class, and thereafter approved by Judge Brody and affirmed by the U.S. Court of Appeals for the Third Circuit; the United States Supreme Court declined further review.

* In re Vioxx Prods. Liab. Litig., MDL No. 1657 (E.D. La.); In re Vioxx Prods. Liab. Litig., No. 619 (N.J. Super. Ct. Atlantic Cty). Served as Court-appointed Liaison Counsel (New Jersey proceedings), co-chair of discovery (MDL proceedings), and trial counsel in several bellwether trials against Merck & Co. concerning heart attacks caused by its arthritis drug, Vioxx. Through his role in both the New Jersey and MDL proceedings, Mr. Buchanan helped develop and lead the overall litigation strategy for the approximately 27,000 separate cases pending against Merck & Co., and, together with partner Christopher Seeger, successfully co-tried the bellwether case, Humeston v. Merck & Co., Inc., case no. ATL-L-2272-03, N.J. Super. Ct. Atlantic County, which resulted in a $47.5 million verdict for the Humestons for his Vioxx-related heart attack. Months later, Mr. Buchanan joined with the negotiating committee to help secure the $4.85 billion settlement from Merck for the many people injured by the drug.

* In re Pfizer Inc. Securities Litig., No. 04-cv-9866 (S.D.N.Y.). Served as class and science counsel in this federal securities fraud action against Pfizer on behalf of investors relating to misrepresentations and omissions concerning Pfizer's drugs, Bextra and Celebrex. Mr. Buchanan played a leading role in developing the expert slate to overcome Pfizer's early science challenge, led with partner Christopher Seeger plaintiff's presentation and examinations during the seven day Daubert hearing, and was later asked to serve as co-trial counsel in the trial of the case. Following pre-trial motion practice and ensuing appeals, the case settled, resulting in a $486 million cash settlement fund for the class of aggrieved investors.

* In re Accutane Litigation, No. 271 (N.J. Super. Ct. Atlantic Cty). Since 2005, Mr. Buchanan has served as Liaison Counsel and trial counsel for plaintiffs suffering from ulcerative colitis and Crohn's disease as a result of their use of Roche's acne medicine, Accutane. Several bellwether trials in the multi-county coordinated proceedings have occurred among the several thousand pending cases, thus providing important harbingers to the parties for the broader litigation, e.g.: McCarrell v. Hoffmann La Roche, Inc., No. A-4481-12T1 (N.J.) (trial counsel for Alabama man developing ulcerative colitis shortly after stopping Accutane; $2.5 million verdict in first trial; $25.5 million jury verdict in re-trial); Kendall v. Hoffman La Roche Inc., No. 36 A. 3d 541 (N.J.) (trial counsel for Utah woman who developed ulcerative colitis after stopping Accutane; $10.4 million verdict in first trial; $1.4 million verdict in re-trial); Rossitto & Wilkinson v. Hoffmannn La Roche, Inc., Nos. L-7481-10 and L-1311-08 (N.J.) (lead trial counsel in consolidated trial for this New Jersey woman (Ms. Rossitto) and Utah man (Mr. Wilkinson) concerning their development of ulcerative colitis and resulting complications following the use of Accutane; $18 million verdict for plaintiffs; verdicts vacated on appeal, with further appellate proceedings pending). These contentious proceedings have similarly resulted in several landmark decisions from the New Jersey Supreme Court and the New Jersey Appellate Division-in which Mr. Buchanan has served as appellate counsel-on legal issues of wide import, including choice of law, the discovery rule applicable in products liability claims, the presumptions afforded under the New Jersey Products Liability Act, and the admissibility of expert scientific testimony.

* Zylon Corp. et al. v. Medtronic, Inc. et al., No. 650523/2008 (N.Y. Supreme). Represented inventor, Zylon Corp. and its principal, in theft of trade secret and unfair competition case against Medtronic, Inc. in New York Supreme Court, Commercial Part. Plaintiffs' contention: through a series of agreements designed to provide Medtronic an opportunity to evaluate Zylon's proprietary technology, Medtronic accessed, misappropriated, commercialized, and, later, claimed as its own Zylon's proprietary process for making "zero fold"-or extremely low profile-angioplasty balloons. Following protracted and contentious proceedings, Mr. Buchanan served as trial counsel with partner Terrianne Bennedetto and co-counsel of behalf of the inventor in the multi-week trial. The parties resolved the litigation on the eve of closing statements.

* In re Depuy ASR Hip Implants Litig., MDL 2197 (N.D. Ohio); In re Depuy ASR Hip Implants Litig., No. 293 (N.J. Super. Ct. Bergen Cty). Appointed Lead Counsel by the Hon. Brian R. Martinotti for the coordinated New Jersey proceedings against Johnson & Johnson and subsidiary Depuy Orthopaedics on behalf of thousands of victims who received Depuy's defective ASR hip replacement, which resulted in revision/replacement surgeries, infections, and further complications. Mr. Buchanan led discovery in the state proceedings (and further assisted with MDL discovery), and was selected as co-lead and lead counsel for the first MDL and state bellwether trials, respectively. Plaintiffs reached a global settlement-now estimated at approximately $3 billion-as Mr. Buchanan's first New Jersey bellwether trial was set to commence.

* In re Stryker Rejuvenate & ABG II Modular Hip Implant Litig., No. 296 (N.J. Super. Ct. Bergen Cty). Appointed to the Plaintiffs' Steering Committee by the Hon. Brian R. Martinotti in claims against Stryker Corporation and its subsidiary Howmedica Osteonics Corp. related to its defective Rejuvenate and ABG II hip replacement system. The plaintiff-patients suffered severe injuries and complications following their hip replacement surgeries, in many cases, resulting in revision surgeries and related or ensuing complications. The litigation resolved favorably (and on an expedited basis) through an innovative bellwether mediation program, from which a global resolution valued at more than $1 billion followed.

* In re Gadolinium-Based Contrast Agents Prods. Liab. Litig., MDL 1909 (N.D. Ohio); In re Gadolinium Contrast Agents Litig., No. 279 (N.J. Super. Ct. Middlesex Cty). Represented numerous injured patients in a mass tort against GE Healthcare, Bayer Healthcare Pharmaceuticals, Mallinckrodt, and others, concerning harm caused from exposure to their Gadolinium-based contrast dyes used in medical imaging. The plaintiff-patients developed a severe, disfiguring, debilitating-and in many cases, fatal-condition known as Nephrogenic Systemic Fibrosis, or Nephrogenic Fibrosing Dermopathy (NSF/NFD)-following routine imaging exams that employed Galolinium-based imaging agents. Mr. Buchanan was appointed Federal-State Court Liaison by the Hon. Daniel Polster for the MDL proceedings, and Liaison Counsel, by the Hon. Jamie D. Happas, for the New Jersey coordinated proceedings. Following extensive discovery, the litigation resolved by settlement on favorable terms for plaintiffs' injured by defendant's products.

* In re Rezulin Prods. Liability Litig., MDL No. 1348 (S.D.N.Y.). Member of discovery team in MDL and coordinated state-court proceedings against Warner Lambert and Pfizer for liver injury claims suffered by hundreds of consumers due to the withdrawn diabetes drug, Rezulin. Served as bellwether trial counsel in Morgado v. Warner Lambert, Pfizer, et al., No. 403243/01 (N.Y. Supreme), which resulted in $2 million verdict for Mrs. Morgado, and set the stage for global resolution of the broader claims in the litigation.
