- Onyx Therapeutics, Inc. v. CIPLA Ltd., et al. (D. Del. and Fed. Cir.): Kevin successfully represented Onyx in this ANDA patent-infringement case involving multiple generic drug manufacturers’ versions of Onyx’s cancer therapeutic Kyprolis® (carfilzomib). Following a week-long trial, Chief Judge Stark found in favor of Onyx. Kevin also represented Onyx in successfully defending against CIPLA's appeal of the judgment in the U.S. Court of Appeals for the Federal Circuit.
- Amgen Inc. v. Hospira, Inc. (D. Del. and Fed. Cir.): Kevin successfully represented Amgen in this BPCIA (biosimilar) case (one of the first cases ever filed under the BPCIA, and the first BPCIA patent-infringement case to be tried to a jury) involving Hospira’s biosimilar version of Amgen’s blockbuster biopharmaceutical Epogen®. After a week-long trial, the jury returned a verdict in favor of Amgen, and awarded Amgen damages in excess of $70 million. He also represented Amgen in Hospira’s subsequent appeal to the U.S. Court of Appeals for the Federal Circuit, which affirmed the judgment and award of damages to Amgen.
- AbbVie Inc. v. Amgen Inc. (D. Del.): Kevin represented Amgen in this BPCIA (biosimilar) case involving Amgen’s Amjevita™ biosimilar version of AbbVie’s blockbuster biopharmaceutical Humira® (the best-selling drug in the world), in which Amgen was able to favorably settle the matter so that it will be able to market Amjevita™ prior to expiration of AbbVie’s patents.
- Pfizer Inc. and Northwestern Univ. v. Teva Pharms., et al. (D. Del. and Fed. Cir.): Kevin represented Northwestern University, which holds several patents covering pregabalin, the active ingredient in the blockbuster drug Lyrica®, in this ANDA case against seven generic-drug-company defendants seeking to market generic versions of Lyrica®. He represented Northwestern in a two-week bench trial before then-Chief Judge Sleet in Delaware, following which Judge Sleet entered judgment in favor of Pfizer and our client on all issues. He represented Northwestern in the defendants’ subsequent appeal in which the Federal Circuit affirmed all aspects of the district-court judgment.
- Life Technologies Corp. v. Illumina, Inc. (D. Del., S.D. Cal., and Fed. Cir.): Kevin represented Illumina in this case in which Life Tech and Illumina each alleged infringement by the other of multiple patents covering systems and methods for DNA amplification, detection, and sequencing. The action was filed in Delaware, but was transferred to the Southern District of California, where Judge Bencivengo granted our motion for summary judgment of non-infringement on all of the asserted claims in Life Tech’s patents, and Judge Moskowitz denied Life Tech’s motion for reconsideration of that judgment. Life Tech dismissed its subsequent appeal to the Federal Circuit.
- Applera Corp.–Applied Biosystems Group v. Illumina, Inc. (N.D. Cal. and Fed. Cir.): Kevin represented Illumina in this case concerning the ownership and infringement of patents covering “next-generation” ligation-based DNA sequencing methods. During a month-long trial, the jury found in favor of Illumina regarding ownership of the patents-in-suit and regarding validity of one of the patents. He successfully represented Illumina in Applera’s subsequent appeal to the Federal Circuit.
- Vanderbilt Univ. v. ICOS Corp. (D. Del., Fed. Cir., and SCOTUS): Kevin represented ICOS (now part of Eli Lilly & Co.) in this case in which Vanderbilt sought to add its scientists as co-inventors to patents covering the manufacture, sale and use of tadalafil (the active ingredient in the blockbuster anti-impotence drug Cialis®). Following a two-week bench trial in Wilmington, Delaware, then-Chief Judge Robinson entered judgment in favor of ICOS. He successfully represented ICOS in Vanderbilt’s subsequent appeal to the Federal Circuit and petition for certiorari to the U.S. Supreme Court.

Cir.): Kevin was co-lead trial counsel for Amgen in this case involving Amgen’s patents covering EPOGEN®, the recombinant form of human erythropoietin (“rEPO”) that stimulates the production of red blood cells and is one of the most successful biotech pharmaceutical products ever. After a six-week trial, the Boston jury returned a verdict in favor of Amgen on all counts (Judge Young had earlier granted summary judgment of infringement with respect to one of the patents-in-suit). Judge William Young entered both preliminary and permanent injunctions against the defendants. The Federal Circuit affirmed the judgment, and the case settled on favorable terms for our client shortly thereafter.
- Amgen Inc. v. Hoechst Marion Roussel and TKT (D. Mass. and Fed. Cir.): Kevin successfully represented Amgen in two patent-infringement trials in Boston, and two Federal Circuit appeals by the defendants, in this case involving Amgen’s patents covering EPOGEN®.
- Default Proof Credit Card System v. Home Depot (S.D. Fla. and Fed. Cir.): Kevin successfully represented Home Depot in this multi-defendant infringement action in which Default Proof alleged that Home Depot and several other major retailers (including Wal-Mart and Starbucks) infringed a patent relating to retail gift-card systems. He obtained summary judgment of invalidity for indefiniteness (under 35 U.S.C. § 112 ¶ 6) on all asserted claims in the trial court, and was also successful in defeating Default Proof’s subsequent appeal in the Federal Circuit.
- Schering Corp. v. Geneva Pharmaceuticals, Inc. (D.N.J. and Fed. Cir.): Kevin represented Geneva Pharmaceuticals (now Sandoz) in this multi-defendant ANDA case involving generic versions of the blockbuster drug Claritin®.

- Applied Research Systems v. Cell Genesys Inc. and TKT (D. Mass.): Kevin represented Applied Research Systems (a subsidiary of Merck-Serono) in these consolidated 35 U.S.C. 146 and patent-infringement cases involving the appeal of an interference decision on ARS’s patents and CGI’s patent application directed to methods of endogenous gene activation, and the alleged infringement of ARS’s patents by TKT’s “gene-activated” recombinant products. After then-Chief Judge Wolf granted our motion-in-limine to exclude much of CGI’s evidence in the § 146 action, CGI and TKT settled the actions on very favorable terms for our client.
- Danisco A/S et al. v. Novozymes A/S et al. (S.D.N.Y.): Kevin represented Danisco in this case involving Novozymes’s alleged infringement of Danisco’s patents covering recombinant lipase enzymes and their use in industrial bread-making. Following successful motion practice, we were able to settle the case on terms favorable for our client.
