Filament LegalPatents & Trademarks

A trademark office action gives you three months, and the extension is neither free nor automatic.

A refusal is not the end of your application. Missing the deadline is. Bring us the letter as soon as it arrives, whoever filed the application originally.

Most refusals fall into three categories.

Which one you are facing changes the response completely, and two of the three are frequently answerable with evidence you already have.

01

Likelihood of confusion

The examining attorney found a registered mark they consider too close for related goods. The response argues the differences in the marks, the goods, the channels of trade, and the buyers, and sometimes negotiates consent from the other owner.

02

Merely descriptive

The mark describes a feature, quality, or purpose of the goods rather than identifying their source. The response argues distinctiveness, offers evidence of acquired meaning, or moves the application to the supplemental register.

03

Specimen and technical refusals

The proof of use does not show the mark as actually used in commerce, or the identification of goods needs amendment. These usually resolve quickly with a substitute specimen and a clean amendment.

The clock is the part that ends applications. The response window is three months. A single three-month extension is available, but only if you file the request and its fee before the original deadline runs out. Applications filed through the Madrid Protocol get six months and cannot extend at all.

Questions we get about this.

What is a trademark office action?

A trademark office action is a written refusal or objection from the USPTO examining attorney reviewing your application. It explains what is wrong and what has to be addressed before the mark can register.

Receiving one is common and does not mean the application is lost. Most refusals are answerable.

How long do I have to respond to a trademark office action?

Three months from the issue date for most applications. One three-month extension is available, but it must be requested with its fee before the original deadline expires.

Applications filed through the Madrid Protocol under section 66(a) get six months and no extension is available at all. Missing the deadline abandons the application.

What happens if my application goes abandoned?

An abandoned application cannot be revived except in narrow circumstances, generally where the delay was unintentional and a petition is filed promptly with its fee.

Otherwise you refile, which means losing your original filing date and any priority that came with it. That lost date is the real cost of a missed deadline.

Can you respond to an office action on an application I filed myself?

Yes, and a good portion of this work arrives that way. Send us the office action and the application, and we will tell you what we think is answerable before you commit to anything.

Come to us early rather than at the end of the window. A response built in the last week is a worse response.
