I would seek professional advice on this one. Before signing any severance agreement with a release of claims clause, it's important to carefully review the terms and consult with a legal professional. If you have any doubts or concerns about the agreement, it's best to seek legal advice to ensure that your rights and interests are protected.

As for the patent application, if you believe that there are factual errors and low-quality drawings that could impact the application's success or enforceability, it may be worthwhile to consult with a patent attorney to explore your options. They may be able to help you understand the potential risks and suggest strategies to address the situation.

Additionally, if you haven't already done so, it may be worthwhile to communicate your concerns to the company in writing. This could include an email or letter outlining your concerns regarding the rough draft and explaining the potential consequences of filing the patent application in its current state. This documentation may be useful in the event of any future disputes or legal actions.
