Hell, if I found out you owned the holding company with the patent, I'd probably not hire you for the same reason.
Precisely one of my concerns and similar to the sentiment others have issued merely for having an industry patent, much less a holding company. I'm not trying to be dishonest, and frankly I wouldn't have minded if more people recommended granting a limited non-exclusive license to an employer; really I was hoping that a few inventions would look good on a resume. I'm rather taken aback by the number of people that actually perceive it as a negative. Thanks for the feedback; I don't want a holding company be a negative any more than some IP. More to consider, thank you.
Take all the comments (including this one) with a grain of salt. You're not getting a representative sample of potential employers and managers (who are likely to care more about what you can bring to the bottom line than about ideological purity in their hiring practices). Sure, there are some employers and managers who will base hiring decisions on knee-jerk reactions against patents, but probably not that many. Many, in fact, are going to be interested in your experience with the patent system since they may not have had direct experience with it. If it looks like you're going to make it more trouble than it is worth to hire you, then that may put off a number of employers. But, if you keep it simple and fair, you'll look like you have something beyond coding savvy.
You probably do want to talk with a decent patent attorney to get an idea what you really have in terms of legal protection and how you might negotiate a reasonable deal. Your claimed invention may be so narrow that it would be almost impossible to infringe on your patent claims without deliberate effort, especially if you prosecuted the patent applications yourself without much experience or in depth advice. Or you may have gotten something so broad that the patent claims are unlikely to withstand scrutiny if challenged. And did you have any co-inventors, named or unnamed? That can complicate things since co-inventors, by default, can independently license patent rights (in a corporate setting, the inventors typically assign the rights to the company so that only one entity has the licensing rights).
On the other hand, you may have something of value to a potential employer, especially if an exclusive license or assignment was on the table. You wouldn't be able to use the technology on your own if your employment ended, so it would be reasonable to expect something of value in exchange. Maybe the compensation could come in the form of a nice sign-on bonus, or perhaps a termination payout if they don't keep you for X number of years as an employee (wouldn't that be nice to have if a round of layoffs hit your department?)
At the very least, your employer will probably want to have at least a non-exclusive license right to use your patented invention. If the patents were assigned to a former employer who didn't want to license any patent rights, your new employer could at least have you work on engineering around the claims of the patents. But, they probably are going to be very annoyed if you insist on having them pay you to engineer around patent claims when you also have the authority to license those very same claims to them at any rate you desire, especially if you are the one who made the technology sound so useful in the first place. And what if co-workers learn from you and independently produce technologies that infringe on your patents? What a mess that would be. A simple non-exclusive license, paid upfront, would make a lot of potential problems go away.
What is it all worth? I don't know. Don't expect much if all you are offering is a non-exclusive license to a poorly drafted patent with narrow, invalid claims. But, if you can offer exclusive rights (including the right to sue) to a well-drafted patent with broad, valid claims, then try to get a decent bargain. After all, if potential employers don't want to deal with your patents as an employee, then you have the option of starting your own company (perhaps with some venture capital backing) and letting them deal with your patents as a competitor.
Or you could just donate your patents to the Open Invention Network, and list them on your résumé as evidence that you can document technology, and even help secure patents, but you aren't going to try using your own patents as bargaining chips. Hey, they're your patents, do what you want with them.
