"The U.S. patent law system is among the most lenient in the world with regards to prior disclosure of your invention. It allows you to publish your invention or offer it for sale prior to filing a patent application, provided that you file your patent application within one year of the publication or offer for sale."

I have 3 patents to my name.

While I list them on my resume as part of my accomplishments, I have never offered them, for free, or for a licensing fee, to a prospective employer. In my opinion, their value is in showing your employer that you have skills, not as some 'package deal' where one buys you, and gets the tech for free.

Absolutely agree.
Back when I worked in the cards technology department at Citi, Mitchell Habib implemented a similar system when he took the CIO position. I had a new job within 2 weeks. Not because I felt like I was a bottom performer. In fact, I was told that I was a top performer, and they would often bring me in on projects that were lagging, in order to get things done on time. But I absolutely despise these kinds of systems, and I could foresee the huge morale hit that would take place when it was implemented. I wasn't the only top-tier guy that left...a small handful of us who had been around the block a few times saw what lay ahead and went on to greener pastures.

And if you don't know how things shook out with Mitchell Habib and Citi, take a look here.
