In order to keep a trademark active, you must submit continual filings evidencing that the trademark holder is using the trademark in commerce. The first filing must be made between the 5th and 6th year after registration. The second must be made between the 9th and 10th year after registration and then every 10 years after that. If you do not make these filings, the trademark will eventually be deemed abandoned. You can check the USPTO database to see if these filings were made. Hope that helps.
Are you trying to hold onto trademark rights you once had, or merely trying to re-register a mark in which you claim to continue to maintain rights? You seem a little confused about how trademark law works in the U.S. and are not understanding the significance of the usage of a mark and common law rights. If you are concerned about maintaining rights to a mark that someone else is threatening, you promptly need to consult an attorney or you will surely jeopardize your rights in the mark.
A trademark registration just reinforces and nationalizes trademark rights that you establish from use of the mark in U.S. Commerce. That registration lapses automatically if the necessary Section 8 Declaration of Continuing Use and its filing fee is not filed by each due date as well as the renewal due each 10th anniversary from the registration date. If a registration lapses, you can always file another application to register the mark again and claim all of the prior usage in the new registration. You could have trouble re-registering the mark because of an intervening filer or user of a similar mark or if the current examiner decides the registrability of your mark differently than the initial registration - those are the risks you face when allowing the registration to lapse.
But you ultimately need to keep using the mark, and show clear intention to resume use if a period of non-use occurred, in order to maintain rights in the mark regardless if the mark is registered or not. If the third party is trying to obtain the mark on the basis that you abandoned the mark for non-use, they can do so based upon a presumption of abandonment if the mark has not been used for a period of 3+ years and evidence of your intent to have stopped using the mark without any intention to resume use.
Petitions to cancel a registration require that you have rights in a mark that is jeopardized by the continuing registration of the respondent you petition. The grounds for petitioning a registration are also significantly limited if the registration is older than 5 years.
Alex Butterman is a trademark attorney with Staas & Halsey LLP (http://www.staasandhalsey.com), a Washington, D.C. IP boutique law firm. Alex is admitted to the bars of Washington, D.C., New York and New Jersey but, unless otherwise specified, the answer is intended to be general enough to apply to any U.S. state and based primarily upon his knowledge and experience with applicable federal laws. The opinions expressed are those of the author and do not necessarily reflect the views of his firm, Avvo or other attorneys. This answer is for general information purposes only and is not intended to be and should not be taken as legal advice. No attorney-client relationship or obligations are established herein, although consulting an attorney to discuss your specific situation is strongly recommended. This is especially true of trademark law because TM law is so fact-specific and full of esoteric nuances and exceptions that could easily result in a critical legal error without proper advice from experienced trademark counsel.
If branded goods are not sold for three years then the law presumes that the brand-identifier [the trademark] no longer serves to brand that good -- and so the former user of the mark cannot enforce the mark, which is then free to be used by others.
However, because the law strongly disfavors the abandonment of trademark rights, it takes very little effort to prevent the abandonment. Perhaps simply advertising the branded goods suffices [even though no sales are made]. Each case is very fact specific. Your own trademark attorney should review your particular facts in private. Good luck.
