Which professionals are involved in the Duty to Disclose?

The correct answer highlights the comprehensive nature of the duty to disclose relevant information during the patent application process. This duty is not limited to the inventors alone; it extends to several parties involved in the prosecution of a patent. Specifically, it includes inventors, as they have firsthand knowledge of the invention and its background, and thus, they bear a significant responsibility for ensuring that all pertinent information is disclosed.

Additionally, past and present attorneys play a crucial role since they are responsible for handling the legal aspects of the patent application and must ensure that all required disclosures are made. Their legal expertise helps to navigate the complex regulations surrounding patent disclosures.

Experts involved in the prosecution process may also have insights into relevant prior art or information that needs to be disclosed to the Patent Office to avoid potential issues of inequitable conduct. This broad scope of involved professionals helps maintain the integrity of the patent examination process by ensuring that all pertinent information is presented to the examiner.

In contrast, the other options focus too narrowly on one group or exclude key participants in the patent prosecution. These narrower interpretations do not encompass the full range of individuals who hold responsibilities under the duty to disclose. Thus, the answer reflects an accurate representation of all parties charged with the obligation to disclose relevant information.
