Kathy’s practice focuses on analyzing patents across a breadth of technologies areas – from software to pharmaceuticals. Over the past decade, she has evaluated thousands of patents, drafted nearly fifty opinions of counsel, and guided her clients in patent portfolio strategy and management. Kathy provides both offensive and defensive analyses to ensure her clients’ innovations are well protected in the marketplace. From the inception of the America Invents Act (AIA), Kathy has been representing clients in post-grant proceedings.

An active participant in her community, Kathy volunteers with Girls, Inc., which is an organization designed to inspire and support underprivileged girls in the Denver Metro area. She gives of her time to work with girls in keeping with the organization’s initiatives, including mentoring, educational enrichment, and math and science programming.  She also serves on the Advisory Board for Eureka!, which is a Girls Inc. program centered around STEM enrichment. Recently, she developed a curriculum for a four-week high school internship program at Merchant & Gould’s Denver Office. Believing strongly in public service, Kathy provides pro bono legal assistance to immigrant victims of domestic violence and provides pro bono patent services through ProBoPat. As a Steering Committee member of ProBoPat, she works alongside the U.S. Patent & Trademark Office, Mi Casa Resource Center, and the Colorado Bar Association to promote and guide the Rocky Mountain pro bono patent initiative.

Representative Post-grant Proceedings:

Kathy has had repeated success representing clients in post-grant proceedings before the U.S. Patent Trial and Appeal Board (PTAB). Representative cases centered on technologies including remote healthcare monitoring, boron-containing topical pharmaceuticals, particle-enhanced water-permeable textile membranes, and network security, and include:

  • Cardiocom LLC v. Robert Bosch Healthcare Sys., Inc., IPR2013-00468, IPR2013-00469 (U.S. Patent No. 7,516,192) (Final Written Decision holding all claims challenged in two petitions unpatentable);
  • Coalition for Affordable Drugs X LLC v. Anacor Pharms. Inc., IPR2015-01776, IPR2015-01780, IPR2015-01785 (U.S. Patent Nos. 7,582,621 & 7,767,657) (Final Written Decisions holding all claims unpatentable for both patents challenged in three petitions) (affirmed on appeal, Anacor Pharms., Inc. v.

Offensive and Defensive Patent Analysis:

Kathy has over a decade of experience providing offensive and defensive analyses in the fields of medical device technologies, pharmaceuticals, and computer science and software. For instance, she provides offensive product mapping, invalidity claim charting, product clearance, pre-acquisition due diligence, directed prosecution based on a target product or licensing agreement, full-scale non-infringement and invalidity opinions of counsel, and ANDA Paragraph IV Certification opinions of counsel. Representative projects include:

  • Managed a team of attorneys to conduct pre-acquisition due diligence for one of her clients, resulting in the successful acquisition of the company; the project involved reviewing hundreds of patents, clearing seven distinct product lines, advising on product design-around, and delivering twenty opinions of counsel.
  • One of a select team of attorneys engaged to assess hundreds of patent claim charts supporting a multimillion-dollar software licensing negotiation involving software, hardware, semiconductor & telecommunications. 
  • Drafted over 50 claim charts directed to a target product or a licensed technology and performed directed prosecution based thereon.
  • Drafted multiple opinions of counsel supporting Paragraph IV Certification for Abbreviated New Drug Applications (ANDAs) in the area of Orange Book pharmaceuticals.
  • Conducted clearance investigations for multiple product launches, including reviewing thousands of patents and drafting numerous non-infringement or invalidity opinions of counsel.

Patent Preparation and Prosecution:

Kathy has over a decade of experience preparing and prosecuting patents, including expertise in a variety of fields. For instance, Kathy has extensive experience prosecuting computer science and software-related subject matter, including network protocol technologies, artificial intelligence, natural language processing, virtual/augmented/mixed reality display environments, database structure and management, garbage collection and memory allocation management, block-chain technologies, cryptography, productivity suite application features and functionality, and graphical user interface features and functionality. She also has a high level of experience prosecuting medical devices, including acute-care ventilators, orthopedic fixation devices, spinal implants, ultrasound localization marker technologies, ultrasound liposuction devices and tools, and surgical cutting devices and tools. She has also prosecuted in the chemical field with respect to biofuel production and purification.

Kathy has counseled clients for many years in patent portfolio management and strategy. For instance, for the past nine years she has managed a large prosecution docket in the medical-device field, including both software-related and mechanical innovations, and for the past four years she has managed a quarter of the firm’s large prosecution docket for a fortune-50 software company.
