Patent Office Examinations - Reexaminations

Finnegan attorneys have handled more than 270 reexaminations in the last five years. Under the America Invents Act (AIA), ex parte reexamination proceedings, which have unique rules and procedures, remain an important option to consider when challenging the validity of a patent. We are experienced in all procedural aspects of reexamination and regularly advise clients on litigation strategies that include reexaminations as offensive or defensive tactics. And as a recognized leader in reexaminations, other AIA proceedings, and patent litigation in district courts and before the International Trade Commission, Finnegan attorneys have an educated and distinctive perspective on how best to utilize the reexamination proceeding as part of an overall strategy for attacking a patent.
