We're not lawyers, most of us, so we're quite the wrong crowd to base a decision on that could result in your financial ruin.
Have you consulted with an IP lawyer or a TM lawyer? If not, why not?
Let's turn this thread around, if you don't mind, for the alternative is that the thread will be closed due to the Domain Forum Charter provisions regarding trademark. Basically the Charter provides that we don't act as unqualified and ill-informed lawyers in matters that may affect individuals or companies directly.
Play with me and we'll see where it goes. We may be able to offer some initial suggestions, even though we will not be able to answer your question directly or in any meaningful or reliable or trustworthy way.
First questions I have:
1. Why haven't you consulted with an intellectual property (IP)lawyer?
2. What online legal resources, dedicated to IP law have you consulted? If the answer is "none" then please do a bit of searching and report back what you have found about available resources. You might want to check the government trademark sites to begin. You might look for "law journal" sites operated by various law schools. You might want to see if there's any organizations dedicated to "intellectual property law" or "trademark law". (You can't be BOTH cheap/poor AND lazy AND be successful in business, right? So, if you can't hire a lawyer seek out the most authoritative free resouces.)
3. What country do you live in? What country is the headquarters of the company whose product you are targeting? Where does that country "do business"? I ask the latter question because you might be subject to an infringement claim in every country where the parent company has registered their trademark?
4. Have you checked to see where the company has registered its trademark?
5. Has this company filed any WIPO or National Arbitration Forum complaints?
6. Has the company filed any trademark infringement lawsuits? (Search for "company name" + litigation, lawsuit, trademark infringement, etc.)
Now, hopefully you will play along.
Or, maybe, you'll throw up your hands as you begin to appreciate just how challenging the topic is.
I hope you choose to play along.
DON'T NAME THE COMPANY, at least not at this time, especially if you intend to move ahead with this project. (Read the Charter for an explanation why I say this.)
