Recent Representative Matters

  • Boehringer Ingelheim v. Genentech. Currently representing Genentech in responding to petitions for inter partes review in the Patent Trial and Appeal Board of three patents relating to methods of using rituximab, one the largest selling biologic treatments for cancer and rheumatoid arthritis. Petitioner Boehringer Ingelheim is currently running clinical trials on a biosimilar version of rituximab that is expected to be the subject of an application for FDA approval under the Biologics Price Competition and Innovation Act.
  • RainDance Technologies et al. v. 10X Genomics. Currently representing 10X Genomics in a patent litigation suit filed in the District of Delaware relating to methods of preparing DNA samples for sequencing through the use of microfluidic technology.
  • Ariosa Diagnostics, Inc. v. Sequenom, Inc. Represented Ariosa Diagnostics in a declaratory judgment action filed in the Northern District of California against Sequenom. After initially defeating Sequenom’s effort to secure a preliminary injunction to enjoin Ariosa from selling its Harmony Prenatal Test (an affordable, highly accurate, non-invasive blood test to assess the risk of fetal chromosomal abnormalities), Ariosa was successful on an early summary judgment motion that invalidated Sequenom’s patent for failing to claim patent-eligible subject matter. The decision gave Ariosa a complete victory and is among the first district rulings invalidating a diagnostic patent in the life sciences field on Section 101 grounds. 
  • Verinata Health, Inc. v. Ariosa Diagnostics. Currently representing Ariosa Diagnostics in two consolidated patent infringement suits in the Northern District of California which, like the action involving Sequenom, seek to enjoin Ariosa from selling its innovative non-invasive test for fetal chromosomal abnormalities. Ariosa persuaded the district court to stay both cases, involving three patents, pending appeals from decisions in inter partes reviews of two of the patents and an ongoing inter partes review of the third patent.
  • Koninklijke Philips N.V. et al. v. ZOLL Medical Corp. and Koninklijke Philips N.V. et. al. v. ZOLL Lifecor Corp. Currently representing ZOLL Medical Corp. in two cases pending in the District of Massachusetts and ZOLL Lifecor Corp. in a case pending in the Western District of Pennsylvania, in which both ZOLL entities have been sued for patent infringement relating to external defibrillator technology. After Irell took over the cases from other counsel in the wake of a loss on the liability phase in one of the two Massachusetts cases, ZOLL was able to persuade the Court to stay the damages phase of the case pending the parties’ cross-appeals of the liability verdict and then successfully negotiated a settlement of the other Massachusetts case. The Pennsylvania case is ongoing and a trial date is expected to be set for 2016.
  • PDL BioPharma, Inc. v. Genentech, Inc. and F. Hoffmann-La Roche. Represented PDL BioPharma in this action filed in Nevada state court alleging breach of a 2003 settlement agreement that, among other things, barred Genentech from taking any action to challenge the validity of certain PDL patent rights. After extensive discovery and motion practice, the case was stayed by agreement of the parties pending Genentech and Roche’s interlocutory appeal to the Nevada Supreme Court of a trial court order granting PDL’s motion to compel them to produce critical documents withheld on grounds of privilege. The case settled during the appeal, with Genentech entering into amended license agreements with PDL. Certain details about the settlement can be found in PDL’s public disclosures.
  • MedImmune v. Genentech and City of Hope; Centocor, Inc. v. Genentech and City of Hope; Bristol Myers Squibb v. Genentech and City of Hope. Represented City of Hope in a series of declaratory judgment actions attacking patents co-owned by Genentech and City of Hope that cover fundamental processes relating to recombinant antibodies. All cases were resolved on favorable terms with no findings of invalidity, unenforceability or non-infringement.
  • Alnylam Pharmaceuticals, Inc. et al. v. Whitehead Institute for BioMedical Research, et al. Represented Alnylam and Max Planck Institute in complex patent dispute in the District of Massachusetts concerning rights to fundamental technology covered in two families of patent applications in the field of RNA interference. Successfully resolved the case on favorable terms through a creative settlement that used co-ownership rights and other cooperative mechanisms to overcome PTO rejections in both patent application families.
  • University of Utah v. Alnylam Pharmaceuticals, et al. Currently representing Alnylam, Max Planck Institute, Whitehead, Massachusetts Institute of Technology, and University of Massachusetts in a lawsuit in the District of Massachusetts over inventorship rights to patents in the RNA interference field co-owned by the defendants. In this case, Irell & Manella represents all of the parties involved in the lawsuit listed above, including the parties who were adverse to Alnylam and Max Planck Institute in that lawsuit.
  • Aon Corporation v. Guy Carpenter & Company. Represented Aon Corporation, one of the world’s largest insurance and financial services companies, in a declaratory judgment action filed in the Southern District of New York relating to a competitor’s patent relating to graphical representations of insured risks and related weather and catastrophe data. Successfully negotiated a settlement of the litigation significantly in advance of trial.
  • CooperVision, Inc. v. CIBA Vision, Inc. Represented CooperVision in multiple lawsuits in multiple forums (the District of Delaware and the Eastern District of Texas) in actions involving cross-allegations of infringement of patents relating to certain core technologies used in contact lenses. CooperVision successfully resolved the case through an innovative cross-licensing arrangement.
  • DataTreasury Corporation v. NCR Corporation. Represented NCR in a patent infringement suit relating to electronic processing of financial transactions. Achieved very early settlement on favorable terms, while multiple defendants in related cases involving the same patents reportedly paid eight-figure settlements.
