  • Replying All to Email Messages – On November 7, 2022, David Hricik discussed the recent ABA ethics opinion Formal Ethics Opinion 503 (Nov. 2, 2022) (PDF here.) regarding permission to communicate with opposing counsel’s client when the opposing counsel cc’s the client to an email message. Generally, the opinion suggests that responding to the email message in a “reply all” mode should be interpreted as “invited” by opposing counsel, note that an ABA ethics opinion lacks authority in most states, so be careful. (Details here.).
  • Prosecution Disclaimers – On November 16, 2022, Professor Dennis Crouch discussed the Federal Circuit’s decision in Cupp Computing AS v. Trend Micro Inc., Nos. 2020-2262, 2020-2263, 2020-2264, slip opinion (Fed Cir., Nov. 16, 2022) (PDF here.). The opinion discussed prosecution disclaimers, wherein patentees are not permitted to recapture through claim interpretation specific meanings disavowed during prosecution. However, the disavowal must be clear and unmistakable to preclude such recapture. The opinion also held that prosecution disclaimer in an IPR proceeding is binding in later proceedings, before the USPTO or in court. (Details here.).
  • Patent Law Year in Review – On January 7, 2023, Professor Dennis Crouch gave a presentation of significant developments in patent law from 2022.

Key points:

  1. Director Review and Ex Parte Lobbying: Exercising the constitutional right to petition the government via shadow request for director review.
  2. Full Scope Enablement and Written Description: Increased focus by both the USPTO and the Federal Circuit. Pending SCOTUS cases of Amgen v. Sanofi and Juno v. Kite.
  3. Patents as Commodity: Many folks are treating it as such.
  4. Broad IPR Estoppel: CalTech v. Broadcom/Apple. Pending before the Supreme Court.
  5. Who is the Inventor: AI and Corporation as the inventor. Thaler v. Vidal cert petition likely in January 2023.
  6. EligibilityTropp and Interactive Wearables are not great vehicles for Supreme Court review. Hopefully, IBM petitions its case from IBM v. Zillow.
  7. Patent Venue: Lots still happening in W.D.Tex.  IMO, parties arguing inconvenient venue don’t really care about convenience. Their basic concern is that they want to escape from Judge Albright’s courtroom and raise costs on to the patentee.

  • The Chisum Patent Academy scheduled to hold one seminar in 2020, Boston, Massachusetts on October 1-2, 2020. Instead, the Boston seminar was then scheduled for a time in 2021, due to you-know-what. Well, that didn’t happen. Maybe 2023? For now, the landing page states, “Due to the Covid-19 pandemic, the Chisum Patent Academy has postponed its live seminars.” Check the website for updates and more information at
