[Patentcenter] I can't access Patent Center in Chrome after the maintenance on 05/31/2025

[Randall Svihla]

Hi

The USPTO performed maintenance on Patent Center from midnight to 3:00 AM o Saturday 05/31/2025.  I was trying to file a single document in Chrome starting around 11:30 PM on Friday 05/30/2025, and I couldn't get past the fee calculation page.  I clicked Skip Fees, but it kept taking me to the fee calculation page, and when I clicked Continue, nothing happened.  I logged in and out several times, and finally I was able to file it at 11:55 PM.

After midnight, I tried to access Patent Center, and it took me to the Systems Status and Availability page.  Today, Monday 06/02/2025, it's still taking me to the Systems Status and Availability page, even if I type https://patentcenter.uspto.gov/ directly into the browser address bar.

I deleted all of the USPTO cookies in my Chrome browser, but it didn't make any difference.

However, I can access Patent Center in Firefox, but I prefer Chrome.

I called the Electronic Business Center today, and of course they asked me to clear my cache and cookies, but I'm not doing that because the last time I did that, it caused me problems.  They said they would escalate it.

Has anyone had a similar problem?

Thanks.
