Maintenance Fees: Why an Issued Patent Is a Subscription

Your patent issued. Congratulations. In the eyes of the USPTO, that ribbon-tied document just converted you into a subscriber.

Most founders don't think about maintenance fees until one quietly comes due. Here is how the system actually works, and how to run it so your portfolio stays a strategic asset instead of a slow drain on your runway.

U.S. utility patents don't require annual payments. Instead, maintenance fees fall due at three points: 3.5, 7.5, and 11.5 years after the grant date. Under the 2025 USPTO fee schedule, the undiscounted amounts are $2,150, $4,040, and $8,280, which is roughly $14,470 in lifetime maintenance per patent for a large entity. The schedule is back-loaded, so the real cost questions arrive years after the celebration.

Two moves keep this simple and in your favor:

First, claim the right entity status. Many startups qualify for small entity (60% off) or micro entity (80% off). At micro rates, that same patent's lifetime maintenance drops to roughly $2,900. Confirming your status is one of the easiest ways to protect cash.

Second, calendar the windows. Each payment window opens six months before the due date. Pay inside it, and you are done. The grace period and the 2025 revival penalties exist, but they simply never matter when the dates live in a system you actually watch.

The fee escalation isn't a trap. It's a prompt to make a decision. Six months before each window, run every patent through three questions:

1. Does it cover a product you currently sell?

Practical utility: It protects your margins.

2. Does it block a competitor's product or feature?

Practical utility: It builds your moat.

3. Is it licensed, or likely to be within a year?

Practical utility: It generates return.

If all three answers are no, that patent is renting space on your balance sheet. Letting it go is not failure, it is disciplined capital allocation. Redirect those dollars into new filings on the technology you are actually building now.

Handled this way, maintenance fees become a recurring portfolio review that keeps your IP lean, defensible, and aligned with where the business is going.

If you have a maintenance window coming up and want a clean framework for the keep-or-prune call, that is a worthwhile conversation to have before the date, not after.
