As a complement to Chadbourne's strengths in patent litigation and patent prosecution, Chadbourne has built a strong reexamination, inter partes review (IPR) and post grant review team to service its clients' needs.  These proceedings are a new form of administrative litigation for challenging the validity of an issued patent in a 12-18-month proceeding before a panel of administrative law judges.  Chadbourne has broad experience in such matters and works closely with our clients to develop offensive and defensive strategies to achieve success in these administrative examination proceedings.

Our services include:

  • Patent invalidity searches
  • Patent reexamination, IPR and post grant review opening and responsive briefing
  • Discovery and trial practice
  • Appeals
