Program Materials

This CLE webinar will guide patent counsel on identifying and determining inventorship and will offer best practices for correcting errors regarding inventorship. Our experienced panel will provide perspectives gained from working with the AIA since its passage and outline lessons from recent court decisions.


The question of inventorship is often difficult, particularly when scientists include all parties involved with an invention on the disclosure form. Patent counsel must determine which person(s) is an inventor and how each contributed.

If errors are discovered later the patent application may need to be changed after it is filed. Counsel can correct an application while it's pending or after the patent is granted, so long as errors in listing the inventors were without deceptive intent.

Patent counsel must learn to properly conduct an inventorship determination to avoid complications that result from an incorrect or incomplete identification and determination. Counsel can leverage lessons and practical experiences from working with the AIA from our panel of experienced patent practitioners.

Listen as our authoritative panel explains determining inventorship, naming the applicant, and managing new forms and procedures related to inventorship. The panel will review the duty of candor, best mode as applied to the inventors, and recent court treatment. The panel will also offer their perspectives and guidance for correcting or changing inventorship.
