C3 Patent and Intellectual Property Law

What happens to patents when a company closes.

A couple days ago someone found this blog by searching for “what happens to a patent when a company goes out of business,” which is surprising, because I don’t recall posting on that. At least it’s less disturbing than the time this blog was found by someone searching for “how to seduce a swan” (I hope they were looking for this.

So, what happens to a business’ patents when the business closes? The answer is pretty close to what you’d hear if you asked “what happens to a business’ copy machine when the business closes?” Patents are property, intellectual property, and even though they differ from physical property in certain ways, in many ways they’re the same.

A closing business can do any number of things with a patent. It could assign or license it to someone, the patent could be part of the company’s assets in a bankruptcy reorganization or liquidation; it could auction it off or dedicate it to the public; the patent could also be left to expire on its own.

The “expiration” is probably what people mean when they ask what happens to patents when the owner goes out of business or dies. For a patent to remain in force, periodic maintenance fees need to be paid to the government. Whether this is for a laudable reason, such as prompting the early public dedication of unused patents or if it’s just another way that the government can extract money from people is a question you can mull over later.

Currently these fees are due at 3.5 years, 7.5 years, and 11.5 years after the patent issues. The cost of these fees increases with each payment. The first maintenance fee is $980, the second is $2480 and the third is $4110 for a large entity and half that for a small entity. I’ve never thought of it before, but those are some strange amounts. If anyone can explain them to me, please leave a comment.

If those fees aren’t paid, the patent expires prematurely. If they are paid, a utility patent will normally expire 20 years after its filing date.

So I guess the answer to the question is closer to that for “what happens to a business’ car when it closes?” Not unlike a car, a patent can be sold, transferred, etc. Also, if a patent is left to languish and isn’t maintained it can be irretrievably lost.

If you’re concerned about a patent, the best thing to do is to have a patent attorney research the patent’s file and determine the best course of action.
