Recent Representative Matters

  • Boehringer Ingelheim v. Genentech. Secured a complete victory for Genentech in responding to petitions for inter partes review (IPR) in the Patent Trial and Appeal Board (PTAB) of three patents relating to methods of using rituximab, one of the largest-selling treatments for cancer and rheumatoid arthritis. Irell persuaded the PTAB not to institute an IPR on one of the three patents. After the PTAB instituted IPRs on the other two patents, Boerhringer Ingelheim requested entry of adverse judgment against it on both patents shortly before Mr. Gindler was scheduled to take the deposition of its expert.
  • Celltrion v. Genentech; Pfizer v. Genentech; and Sandoz v. Genentech. Currently defending Genentech in connection with 15 IPR petitions in the PTAB for multiple patents relating to methods of using Genentech’s blockbuster drug, rituximab. The petitioners are competitors who have filed, or plan to file, for regulatory approval to market biosimilar versions of rituximab under the Biologics Price Competition and Innovation Act.
  • PDL BioPharma v. Merck. Secured a $19.5-million lump-sum payment from Merck to settle PDL BioPharma’s lawsuit filed in the District of New Jersey alleging that Merck’s manufacture of its cancer drug Keytruda infringed a foundational patent relating to the humanization of recombinant antibodies. The case settled little more than one year after it was filed, following the claim construction hearing.
  • Ariosa Diagnostics v. Sequenom. Secured a complete victory for 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), Irell was successful on an early summary judgment motion that invalidated Sequenom’s patent for failing to claim patent-eligible subject matter. The decision was affirmed by the Federal Circuit in a closely-watched appeal.
  • Koninklijke Philips N.V. et al. v. ZOLL Medical Corp. Defeated a $217-million damages claim for ZOLL’s infringement of defibrillator technology patents, and secured jury verdict of no willful infringement. Irell was retained for the damages phase after ZOLL was found to infringe in an earlier liability trial handled by another law firm. Irell initially secured multiple appellate victories for ZOLL on the liability verdict, including overturning the jury verdict that several asserted patent claims were not invalid as anticipated. On remand, Philips sought $217 million on its infringement claims against ZOLL, and ZOLL sought $3.3 million on its infringement counterclaims against Philips. The jury awarded $10.4 million to Philips and $3.3 million to ZOLL, resulting in a net verdict of $7.1 million to Philips.
  • Koninklijke Philips N.V. et al. v. ZOLL Lifecor Corp. Currently representing ZOLL Lifecor in a patent infringement case pending in the Western District of Pennsylvania involving external defibrillator technology. Irell recently won an important Daubert motion excluding critical parts of the opinion of Philips’s damages expert. A trial date is expected to be set for 2018.
  • Bio-Rad Laboratories et al. v. 10x Genomics. Currently representing 10x Genomics in a patent infringement suit filed in the District of Delaware relating to methods of preparing DNA samples for sequencing involving the use of microfluidic technology. Trial is scheduled for April 2018.
  • Illumina and Verinata Health v. Ariosa Diagnostics. Currently representing Ariosa Diagnostics in three 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. The litigation also involves Ariosa’s counterclaims that Illumina breached the parties’ Sale and Supply Agreement for sequencing equipment and supplies by filing suit against Ariosa in derogation of the rights granted under that agreement. Irell defeated Illumina’s multiple efforts to dismiss Ariosa’s counterclaims, including a motion to compel arbitration. Trial is scheduled for January 2018.
  • PDL BioPharma v. Genentech and F. Hoffmann-La Roche. Represented PDL BioPharma in a Nevada state court action alleging breach of a 2003 settlement agreement that, among other things, barred Genentech from challenging the validity of PDL patent rights. After extensive discovery and motion practice, the case was stayed 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. Details about the financial terms of 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 et al. v. Whitehead Institute for BioMedical Research et al. Represented Alnylam and Max Planck Institute in a complex patent dispute in the District of Massachusetts concerning rights to fundamental technology covered in two patent families 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. Secured a complete victory on summary judgment for Alnylam, Max Planck Institute, Whitehead Institute and Massachusetts Institute of Technology in a lawsuit in the District of Massachusetts alleging that a University of Utah professor should have been included as an inventor on patents in the field of RNA interference co-owned by defendants. In this case, Irell represented 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 v. CIBA Vision. Represented CooperVision in multiple lawsuits in multiple forums (District of Delaware and 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 filed in the Eastern District of Texas 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.
