Medical Device and Diagnostics

About

Medical Device and Diagnostics is part of our work in Life Sciences.

Using innovation to improve medical care and patients' daily lives

Finnegan works with innovative clients of all sizes, including Fortune 100, Global 1000, and startups in the medical device and diagnostics industries. Saving lives, enhancing patients’ quality of life, improving healthcare delivery, and creating less-invasive ways to treat diseases are top priorities for the medical device industry. The competitive diagnostics industry seeks to improve testing with faster and more accurate results, as well as to develop new methods to detect evolving targets. Innovators face numerous challenges, including a highly litigious patent environment, tight profit margins, short product lifecycles, reimbursement programs that can affect product viability, and costly research and development activities that often require lengthy clinical trials. In addition, new devices must comply with the U.S. Food and Drug Administration’s safety and marketing regulations, which may require public disclosure of sensitive design information—all before the device is brought to market. To remain competitive, companies must protect and enforce their intellectual property rights.

Understanding the law, science, and technology

At Finnegan, we have the legal experience and technical expertise to help clients address the many issues that arise in developing, protecting, and commercializing medical device and diagnostic inventions. Our experience ranges from working with in-house legal counsel at large companies on prosecution, due diligence, licensing, and high-stakes litigation, to advising senior management of startup companies on strategic business decisions to help get the company off the ground. We understand the highly competitive nature of the medical device industry, the demands of investors and shareholders to generate value, and the importance of securing early and strong protection of IP rights. We also help clients navigate the complex and evolving patent laws that bring challenges to protecting diagnostic inventions.

From determining the competitive landscape for new products to developing winning litigation strategies, we help by:

  • Litigating high value products in district and appellate courts with experienced trial and appellate teams
  • Developing and executing prosecution strategies to both protect a client’s products and analyze those of its competitors, which helps ensure that the client realizes value from its IP assets
  • Advising on and participating in post-grant proceedings, including inter partes reviews and reexaminations 
  • Analyzing the value of competitors’ patents 
  • Preparing and negotiating licenses and other transactions to commercialize IP rights 
  • Counseling on research and development options that minimize patent obstacles 
  • Providing due diligence for merger and acquisition targets 
  • Providing trademark prosecution and counseling services

We work with medical device clients across a broad range of disciplines and technology, including:

  • Diabetes and blood glucose self-testing 
  • Digital-signal processing 
  • Drug-delivery systems 
  • Drug-eluting heart stents 
  • Electronic medical devices 
  • Endoscopy and urology/gynecology systems 
  • Interventional cardiology devices
  • Medical supplies 
  • Monitoring equipment 
  • Orthopedics
  • Surgical devices
  • Therapeutic devices

We work with diagnostics clients across a broad range of disciplines and technology, including:
