**Re: Unauthorized Use of Registered Trademark – Demand to Cease and Desist**
Dear Mr. Corcoran,
I am writing to formally notify you of the unauthorized use of the trademark “Unolingo®” which is owned by me, and to demand that you immediately cease and desist from all infringing activities.
Unolingo is a registered trademark with the United States Patent and Trademark Office (USPTO), Registration No. 3,621,983, registered on May 19, 2009 for use in connection with puzzles, games, and media apps. Specifically, Unolingo is the name of a word puzzle that has been active on USA Today’s gaming site since 2013. The puzzle has also been available as an app for Apple and Android devices since 2011 and is available for purchase in multiple books at Amazon.com. As such, the mark has worldwide standing and recognition.
It has come to our attention that your business interests, Itch Corporation and itch.io are using the mark “Unolingo” in connection with an online game, Android app listing, Google listings, and promotional YouTube videos. Your use of this mark is likely to cause confusion among consumers and constitutes trademark infringement under the Lanham Act (15 U.S.C. § 1114 & § 1125).
Specifically, the infringing use includes (but may not be limited to) use of “Unolingo” in product title and marketing, use of similar logo, domain name, or social media branding, and sale of goods/services overlapping with our trademark class. This unauthorized use misleads consumers and dilutes the distinctiveness of our brand.
**Demand for Action**
We hereby demand that you:
1. Immediately cease all use of the Unolingo mark or any confusingly similar variation in commerce, advertising, online platforms, or product packaging.
2. Remove and/or disable all infringing materials including websites, app listings, social media accounts, store listings, and promotional content displaying the infringing mark.
3. Provide written confirmation within 15 business days of receipt of this letter that you have complied with these demands.
**Reservation of Rights**
This letter is not intended to be a complete statement of our claims or rights, and nothing herein shall be deemed a waiver of any legal or equitable remedies available to us, including seeking monetary damages, injunctive relief, and attorney’s fees should you fail to comply.
We hope to resolve this matter amicably and without the need for legal action. However, if we do not receive a satisfactory response by December 12th, we are prepared to pursue all necessary legal remedies to protect our trademark rights.
Sincerely,
_Ian Mailing_
