Mr. Wexler was lead counsel for Boehringer Ingelheim in connection with Biologics Price Competition and Innovation Act (BPCIA) litigation relating to Boehringer’s FDA request to market Cyltezo®, a biosimilar of Humira®. The case involved a "patent dance" with thousands of pages of detailed statements, claim construction hearings, over 90 depositions, over 20 significant discovery disputes.

Mr. Wexler was lead counsel for Boehringer Ingelheim in Hatch-Waxman litigation in the U.S. District Court for the District of New Jersey, securing victories in multi-defendant litigation involving the blockbuster life-saving blood thinner used by patients at risk of stroke, Pradaxa®, resulting in walkaways from six separate generic defendants.

- Adamas Pharma LLC v. Sandoz
Mr. Wexler was lead counsel for Adamas Pharma LLC in Hatch-Waxman litigation against Sandoz involving patents with method of treatment claims to protect Gocovri™, its flagship product and the first FDA-approved medicine for treating dyskinesia in Parkinson's disease patients receiving levodopa-based therapy, with or without concomitant dopaminergic medications.

- Arena Pharmaceuticals Inc. et al. v. Lupin Ltd. et al.

- Merck Sharp & Dohme Corp. v. Sandoz Inc. et al.
Mr. Wexler was lead counsel for Merck in patent infringement litigation defending Merck’s patent protecting the active ingredient in Emend® for Injection, an important drug for the prevention of chemotherapy-induced nausea and vomiting. After a six-day bench trial, Judge Sheridan of the District of New Jersey entered judgment in favor of Merck on all aspects of Sandoz’s invalidity defenses, resulting in a complete victory for Merck. In the course of the Court’s 80-page opinion finding in Merck’s favor, the Court noted the lack of credibility of Sandoz’s key expert witness who had been cross-examined by Mr. Wexler at trial.
- Sanofi-Aventis US LLC et al. v. Eli Lilly & Co.
Mr. Wexler was lead counsel for Eli Lilly & Co. in litigation with Sanofi regarding Eli Lilly’s request to market its insulin glargine drug product Basaglar®. Sanofi brought suit on five patents, relating to a pharmaceutical composition and injector pen device, listed in the FDA Orange Book for Sanofi’s Lantus® and Lantus SoloStar® insulin glargine products. Mr. Wexler successfully led the case through fact and expert discovery, including live-witness Markman proceedings. The case settled on the eve of trial in late 2015 with the press reporting Eli Lilly’s ability to launch Basaglar® the following year.
- Eisai v. Glenmark Generics, Ltd. et al.
Mr. Wexler was lead counsel for Eisai in litigation with five generic defendant groups involving the patents directed to a crystalline form of rufinamide, the active ingredient in Eisai’s drug product, Banzel®, an important drug in the treatment of epilepsy. After successfully litigating through fact and expert discovery, Mr. Wexler obtained a victory in Markman proceedings having significant implications for the infringement and validity issues in the case. Mr. Wexler also convinced the Court, during the final pretrial conference, to exclude certain purported testing evidence by the defendants offered in support of their invalidity defense. An hour before opening argument at trial, the case settled on favorable terms.
- Merck Sharp & Dohme Corp. v. Apotex Inc.
While district court litigation was ongoing with other generic drug companies, generic drug company Apotex filed a petition for Inter Partes Review (IPR) at the U.S. Patent and Trademark Office seeking to invalidate the patent protecting Merck’s Emend® for Injection drug product. Mr. Wexler obtained a successful ruling from the PTO rejecting Apotex’s invalidity attack and refusing to institute review, and this ruling was subsequently reaffirmed on Apotex’s petition for rehearing.
- Boehringer Ingelheim International GmbH et al. v. Mylan Pharmaceuticals, Inc.
Mr. Wexler was lead counsel for Boehringer Ingelheim in this appeal involving the patent protecting Mirapex®, a key drug in the treatment of Parkinson’s disease. Mr. Wexler was hired to handle the appeal after another firm had received an adverse ruling at trial. Mr Wexler argued and won a complete reversal from the Federal Circuit, with the Court declaring the patent to be valid. The appeal established important precedent concerning the scope of the double patenting safe harbor provision, 35 U.S.C. 121.
- Sandoz Inc. v. Boehringer Ingelheim International GmbH et al.
Mr. Wexler was lead counsel for Boehringer Ingelheim in its counterclaim action for patent infringement against Sandoz. Mr. Wexler argued and won a preliminary injunction ruling, delivered from the bench, preventing Sandoz from launching a generic version of Mirapex®. The court was persuaded to grant the injunction on a patent that had been subject to a license and which would be expiring in several months. The Judge deciding this case in the Middle District of Florida had, in his immediately preceding patent case, refused both preliminary and permanent injunctive relief in part on the ground that the patentee had previously licensed the patent. Mr. Wexler subsequently negotiated a stipulation continuing the injunction through patent expiration.
- Takeda Pharmaceutical Company Ltd. et al. v. Teva Pharmaceuticals USA, Inc. et al.
Mr. Wexler was lead trial counsel for Takeda in two actions enforcing Takeda’s patent for its anti-insomnia drug Rozerem® against challenge by generic drug companies Teva and Watson. After two years of litigation through fact and expert discovery, Mr. Wexler obtained a favorable settlement dismissing both companies’ patent challenges.
- Eisai Co., Ltd. et al. v. Teva Pharmaceuticals USA, Inc.
Mr. Wexler was lead trial counsel for Eisai in an action defending Eisai’s patent protecting Aricept®, the market leading drug for the treatment of Alzheimer’s disease, having sales of some $2 billion/year. Mr. Wexler obtained a preliminary injunction against Teva’s threatened launch of a generic version of the drug. Mr. Wexler ensured continued exclusivity of the patent through patent expiration, and successfully defended attempts by Teva to trigger and run out the regulatory exclusivity of a first-filing generic drug applicant.
- Merck & Co., Inc. v. Sandoz Inc.
Mr. Wexler was lead trial counsel for Merck in an action enforcing Merck’s patents protecting its oral anti-emetic drug product, Emend®. Mr. Wexler ultimately obtained a consent judgment for his client that included an injunction prohibiting Sandoz from infringement through patent expiration.
- Eisai Co., Ltd. and Eisai Inc. v. Teva Pharmaceuticals USA, Dr. Reddy’s Laboratories and Mylan Laboratories
Mr. Wexler was co-lead trial counsel to Eisai in litigation defending Eisai’s patent covering Aciphex®, an acid reflux drug with annual US sales in excess of $1 billion. Eisai initially won summary judgment of patent validity, followed by a successful trial win on the a defense of inequitable conduct. The judgments were then affirmed on appeal. The case established helpful precedent for innovator pharmaceutical companies with respect to the standards for judging obviousness of a compound patent.
- Nycomed v. Teva Pharmaceuticals USA, Inc.
Mr. Wexler represented Wyeth (acquired by Pfizer) and Altana Pharma AG (acquired by Nycomed) in a jury trial against three generic pharmaceutical companies regarding the companies’ $2 billion per year ulcer drug Protonix®. Mr. Wexler successfully examined the inventor of omeprazole, who was also serving as an expert. The jury upheld the validity of the patent, permitting the plaintiffs to seek a damages claim of billions of dollars.
- Warner-Lambert Company v. Teva Pharmaceuticals USA, Inc.
Mr. Wexler represented Pfizer (Warner-Lambert Company) during a successful bench trial against Teva involving Pfizer’s formulation patent covering its highly successful cardiovascular drug Accupril®. Mr. Wexler elicited critical trial testimony from Pfizer’s formulation expert, including refutation of new evidence presented for the first time by the generic’s expert at trial. In its decision, the Court found the patent was not invalid for lack of enablement, despite the breadth of the claims.
