Practical Advice on U.S. Patent Law Issues — Opinion Letters and IPR Filings

March 26, 2019

Webinar

View Webinar

Prudent companies monitor their rivals’ patents. When identifying patents of interest, opinion letters can be useful for business planning, for willfulness purposes in the event of litigation, and to provide a starting point for crafting inter partes review (IPR) petitions. Companies may use IPR petitions during negotiations and heavily rely on them during litigation.

Please join us as we discuss:

  • Opinion letters in pre-litigation and litigation settings
  • Using opinion letters to prepare preliminary IPR or post-grant review (PGR) positions
  • Ensuring consistency between opinion letter positions, IPR petitions, and litigation arguments
  • Using an opinion of counsel to rebut willfulness charges
  • Protecting or waiving the attorney-client privilege

This webinar is the first segment of Finnegan’s 2019 series, “Practical Advice on U.S. Patent Law Issues.” We hope you are able to attend.
