Differentiating Between the Patent Doctrines of Dedication, Disclaimer and Disavowal

On December 6, 2022, Faegre Drinker Partner John Smith presented a webinar to clients and contacts of the Fukami Patent Office P.C. of Osaka, Japan. The session, titled “Differentiating Between the Patent Doctrines of Dedication, Disclaimer and Disavowal,” explained several doctrines that U.S. courts have used to limit patent claim scope. By understanding these doctrines better, prosecution practitioners can take steps to avoid scope-limiting actions and yield stronger patents for their clients, and patent litigators can use the doctrines to help clients overcome accusations of infringement.
