@cq This is straight out bad advice. I work in Legal.
If you take off with work you did at Medtronic as a "sample" and you're busted, you'd better believe they will retain your severance payment and chase you down if it's important IP.
Believe me or not, but I've been on several calls where ex-employees are warned of their breach of contract and required to delete the content in our presence on the call, or send back the whole, untouched USB they used to save it. And yes, MDT has the forensics capabilities to know if you messed with the files after you were given notice.
There is no world where your employment agreement does not contain similar intellectual property provisions.
