What are the solutions for trademark infringement?

Apparently some other user had admitted infringing on your trademark and has offered you a settlement, but you haven't provided enough information for anyone to know what is involved - what kind of sales are involved? Are you supposed to abandon your own trademark rights? If this is a forced license, are you able to maintain quality control? Are you being offered an advance against roaylties, and what are the accounting/audit provisions? See an IP litigator and disclose all the facts of your situation and get some specific advice.

From your question, it sounds like the following is true: you have a fashion accessory brand with a registered trademark and someone else has now almost begun using the same brand name, presumably for the same or similar kind of accessories. Moreover, that person has offered to enter into a deal with you before selling those products on a royalty basis.

This is possible a trademark "licensing" opportunity. Licensing your trademark involves entering a contract with a third party so that party can use your trademark to sell yours or their products. As mentioned in another post, while this is an opportunity, you should be very aware of the various factors that should be addressed in any licensing agreement. While royalties/fees (per unit, per territory, flat fee, etc.), are critical, there are a host of other issues that you should address. These include, termination, quality control, audit rights, non-compete, territorial restrictions and a host of others. In short, if you focus only on the monies, you may end up harming your brand name in the long run, turning the opportunity into a nightmare. Also, it may not be worthwhile to enter into an agreement in the first place, given the nature of the other person's operation and product.

I would consult with an attorney to advise you on the feasibility of entering into such a licese with this gentlemen and to draft a license that addresses these factors. On the flip-side, you may be able to try to bar this person from selling the goods using your brand name and that is something you will definitely need to consult an attorney about.

I hope you found this useful.
