• TOT Power Control, S.L. v. Apple, Samsung, LG (D. Del.):
  In June 2025, Denise led a trial team that secured the second largest patent damages verdict in the District of Delaware this year. After a three-day trial, a jury returned a $110,738,008 verdict for Bunsow De Mory client TOT Power Control against Apple. TOT Power Control alleged that Apple infringed two patents which claimed important technological improvements to 3G technology that enable significant power savings, greatly increasing a mobile phone’s available bandwidth for data. The jury found that Apple infringed one patent, found the patent valid, and awarded a $0.25 running royalty. In 2026, Denise will lead the Bunsow De Mory trial team in TOT’s patent infringement cases against LG and Samsung on the same patents the jury found were infringed by Apple.
  
  

• Inmar Brand Solutions, Inc. v. Quotient Technology Inc. (D. Del., PTAB):
  Denise represented Inmar, an innovative company that specializes in electronic coupon distribution and clearing. She guided Inmar to convert an infringement notice letter it received from a competitor into a major strategic patent win against a different competitor. Inmar obtained an exclusive license to the competitor’s patents and asserted them against Quotient Technologies. Denise led the firm’s procedural and substantive victories in federal court. After the Patent Trial & Appeal Board denied institution on one of Quotient’s IPRs, the case settled favorably for Inmar in July 2025.

• Lambeth Magnetic Structures LLC v. Seagate Technologies (US) Holdings Inc., (W.D. Pa., Fed. Cir.):
  Denise represents Lambeth Magnetic Structures in a long-running patent infringement case against Seagate. Denise secured a big win for LMS when the Federal Circuit reversed the trial court’s claim construction and issued a vacatur on the jury’s verdict against LMS on infringement. LMS’s case against Seagate dates to 2016 when it sued Seagate for infringing a patent that claims a new enabling magnetic structure with a property called uniaxial anisotropy. Disk drive manufacturers use this invention to produce and sell next generation hard drives with greatly enhanced storage capability. Just before summary judgment, LMS brought Denise into the case. She fought off Seagate’s summary judgment motion and tried the case to a jury in May 2022. Based on the erroneous claim construction used at trial, the jury returned a verdict of non-infringement. That verdict has now been vacated by the Federal Circuit’s decision. Denise will be lead trial counsel when LMS’s case against Seagate is re-tried.
