What holds more weight in a trademark appeal - "first use anywhere" or "first use in commerce?"

Your posted facts do not suggest this is an appeal situation; but rather the procedural postulate appears to be a response from you (or your attorney) to an office action is in order - not an appeal. Unless this is a second office action on the same refusal grounds that has been made final, in which case an appeal might be appropriate. And your specific question diving into the priority dates also suggests you need to step back because the priority date analysis is only one part of the analysis of the confusion issue. What's the analysis with the Du Pont factors? For example, is there similarity in the marks? Is there similarity in the goods and/or services? The first use date anywhere, when intrastate, may provide a date for establishing local common law rights in the mark in question - which the USPTO examining attorney might not care about - but you should care about it, because if the two marks are confusingly similar, that registrant could also have superior common law rights over you in wherever that geographical area of first use was. Also, this question suggests a proper clearance search and opinion might not have done and thus you could be facing other unknown but foreseeable litigation, that might be separate and apart from this USPTO office action. If that clearance search and opinion were not done, it should still be done so gauge how much trademark infringement/dilution liability you might be sitting on. In sum, your facts suggest time to consult your own trademark attorney for guidance on this.

If you've just received an Office Action, then you are permitted to respond to that to get the Examiner to change his/her mind. You should hire a trademark lawyer to go over all the facts -- what you've stated above and specifics on the various uses by you and the other registrant -- and then, if the lawyer advises you have a decent argument, to respond to the Office Action for you. No one on here can tell you with any certainty whether you have better rights or whether you have "grounds to appeal," esp. as it sounds like you may not even be at the appeal stage. You also should have had a clearance search before you applied, so if you didn't, this also would be a good reason to engage a trademark attorney. You can find one under the Find a Lawyer tab.

Use anywhere means use in commerce but not interstate commerce such as commerce between another country and the US. Your "at least as early" is subject to different interpretations. You can reply to the office action, but an experience trademark attorney can probably make the arguments better.

Forget the "first use anywhere" date -- it's irrelevant. As for the "first use in commerce" date that's used to specify when in time the applicant is CERTAIN that it first used the mark in commerce to brand the goods or services identified in the application. That listed date, however, could be and very often is far latter in time than, when pressed, the applicant can prove it first used the mark. Because you've been issued an Office Action rejecting your registration application in light of an already-registered mark you need to (1) persuade the Examiner that the refusal is unwarranted [likely because there's no likelihood of confusion] or (2) file a petition to cancel the registration if you, in fact, began use of the same mark before the current registrant or (3) both. You, however, are in way over your head. Your own trademark attorney needs to evaluate the situation and propose a strategy -- which may include abandoning the application and simply using your mark unregistered with the federal Trademark Office or registered with your state's Trademark Office or, worst case, abandoning the mark altogher because the current registrant may sue you for infringement. Lots of variables, lots of options. Good luck.

My colleagues offered good answers to your substantive question. There is a very good reason that even though I am capable of reading an instruction manual I still do not work on my own auto transmission. From the beginning you were really out of the DIY realm, but sometimes people just get lucky with their DIY trademark applications and face no issues. In your case you now have a real issue to deal with and frankly there are no options that will not require some level of a commitment from you to deal with. Or in other words, you need legal help if you want to try and save this mark and if you are not really inclined to invest in that, you would be far better off just starting from scratch with a fresh mark and this time make sure you do your due diligence upfront. But I would explore a best course of action with IP counsel before doing anything. That said, your trademark will be one of if not the most important and valuable business assets you will have and you will ultimately spend more money in support if it than you will anywhere else (advertising, marketing, PR, branding, packaging, etc.). So you owe it to your business and yourself to make sure you handle this properly upfront and the first order of business always starts with a proper and comprehensive clearance. Whenever you endeavor into investing in a trademark it is very important that you conduct the proper clearance due diligence upfront and before you start spending any money in support of it or submit an application to the USPTO. In the US, this means searching under both federal (USPTO) as well as common law because trademark rights stem from use in this country NOT registration. This means that acquiring a federal registration does not necessarily mean that you are not infringing on another's intellectual property. See the link below for a brief article from Fox Business News on the importance of the due diligence process and our overview guide. I suggest that you consult with a lawyer in private and discuss your objectives in more detail. You can start by calling around to several for a free phone consultation, get some insights then pick the best fit to work with. Best regards, Frank Natoli-Lapin, LLC

Because the registrant's application issued prior to your application, the registration was cited against your application strictly based on priority of filing. You do not have to appeal, but can respond to the refusal by providing your arguments and case-law in support of your position. You may also seek a consent agreement from the owner of the cited registration, stating that there is no likelihood of confusion. In these situations, I suggest that you contact an experienced trademark attorney to represent you before the USPTO and advise you on registration and potential infringement issues.
