Did the USPTO issue a 2(d) Refusal for Your Trademark Application?

A 2(d) refusal is issued for a trademark registration application when the examining attorney determines that there is a likelihood of confusion between the mark the applicant applied for and a pre-existing trademark that is already registered in the USPTO database. However, a 2(d) refusal is not always the end of the road for a trademark applicant. You may have a valid argument that would overcome the examining attorney’s refusal to register your trademark. Call us today and let’s discuss the details of your application. We can help you determine if there are any counter-arguments that can be made on your behalf to persuade the examining attorney to allow the registration of your applied-for trademark.

If you tried to register a trademark or service mark for your Chatsworth business on your own, and you received a 2(d) refusal from the USPTO examining attorney, give us a call to see if we can help you overcome that refusal.

Did You Receive A Cease and Desist Letter?

If you have received a cease and desist letter demanding that you stop using a trade or service mark that you thought you had rights to, and your not sure how to respond, don’t panic or jump to conclusions, we’re here to help. Call our experienced Chatsworth trademark lawyer right now to schedule an appointment and let us review the merits of the claims made in the letter. You may have rights that you are not aware of.

We understand that a stern cease and desist letter can be confusing, intimidating, and even frightening. While at times a cease and desist letter is proper and the demand being made is based on legitimate claims, in some cases these letters are nothing more than a scare tactic written to prevent someone from using a trademark or service mark they have every right to use. Don’t try to figure it out yourself – we are here to help. Contact us now and let us schedule an appointment for you.
