Illustrative Professional Experience

  • Cooper Lighting, LLC v. Cordelia Lighting, Inc., Jimway Inc., C.A. No. 1:16-cv-2669-MHC (N.D. Ga.).  One LLP represented a mid-sized Southern California based company accused of patent infringement by a multi-billion-dollar international company.  The asserted patents claimed LED modules to retrofit conventional incandescent and fluorescent downlights.  One LLP successfully moved to dismiss the plaintiff’s willful infringement allegation, greatly limiting plaintiff’s damages claim, and won a crucial venue motion based on a United States Supreme Court decision (TC Heartland) that issued after the complaint and answer were filed in this case.  One LLP prepared, filed, and successfully obtained institution of multiple Inter Partes Review (IPR) petitions challenging plaintiff’s patent validity in the Patent Trial & Appeal Board (PTAB), and convinced the district court to stay the action pending the PTAB’s final decision.  In light of One LLP’s litigation and PTAB successes, the client achieved a favorable settlement just prior to the PTAB’s first decision on patent validity and before the litigation stay was lifted.
