Representative District Court Litigations

  • Cedar Lane Techs., Inc. v. Qualcomm Inc. (W.D. Texas): Secured a complete walkaway victory for Qualcomm in the Western District of Texas after motion practice challenging Cedar Lane's claims for infringement. Cedar Lane accused Qualcomm’s Snapdragon Chips of infringing three patents directed to imaging technologies. 
  • Cedar Lane Technologies, Inc. v. Brother International Corporation (D. Del.): Representing Brother in a patent infringement lawsuit concerning six patents directed to various technologies, including JPEG compression, storage buffering in image processing, auto-cropping of an image, end of session notification, and authentication and secure access for printers in a network.
  • OpenText Corp. v. Alfresco Software Ltd. (W.D. Tex.): Representing defendant Alfresco in a series of three law suits filed by competitor OpenText alleging infringement of nine patents related to enterprise information management technology, including data storage, retention, and synchronization. We succeeded in securing a venue transfer of the three cases to the Central District of California where OpenText also filed suit against Alfresco’s parent company, Hyland Software. Judge Albright granted the transfer sua sponte after originally denying Alfresco’s motion to transfer and while Alfresco’s petition for mandamus was pending at the Federal Circuit.

Cal.): Representing defendant Hyland in two separate litigations filed by competitor OpenText alleging infringement of eight patents related to enterprise information management technology, including data storage, retention, and synchronization.

Cadwalader further narrowed the case during claim construction, garnering a win under Section 112.

Del.): Defended AngioDynamics from the pleading stage through trial against allegations of patent infringement relating to vascular access port medical devices.

Following a successful Rule 50(a) motion, the Court issued judgment of noninfringement, invalidity, patent-ineligibility, and no willful infringement.
