You should proceed by hiring an intellectual property law attorney who handles trademark infringement matters to make that response. You would be very foolish to try yourself to practice law without a license on something so important and nuanced as trademark conflict matters. It sounds like the law firm has a reasonable basis for writing you. You are in more trouble than you think. Get an attorney.
I am not your lawyer and you are not my client. Free advice here is without recourse and any reliance thereupon is at your sole risk. This is done without compensation as a free public service. I am licensed in IL, MO, TX and I am a Reg. Pat. Atty. so advice in any other jurisdiction is strictly general advice and should be confirmed with an attorney licensed in that jurisdiction.
There is a simple answer to your question. Immediately engage a lawyer who's expert in intellectual property disputes involving trademarks andd business names.
This posting is intended for general education and isn't "legal advice." It doesn't create or evidence an attorney-client relationship. You are encouraged to engage an attorney in the pertinent jurisdiction for confidential legal advice on matters of any importance.
s a quick example of why your intuition in TM matters does not correspond to the alw is you complain about how their TM " is a loose term or rather ambiguous." If it were more precise it would not be an OK TM. You need a lawyer who knows TM law.
Licensed in Maryland with offices in Maryland and Oregon. Information here is general, does not create a lawyer-client relationship, and is not a substitute for consulting with an experienced attorney on the specifics of your situation.
I concur with my colleagues. Law is more than "common sense" analysis. Against a company with a lawyer, you will almost certainly not prevail by yourself.
The above is general legal and business analysis. It is not "legal advise" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

I echo my colleagues' responses. YOU shouldn't respond, you should hire TM counsel to respond for you. Frankly, you don't know what "completely different" even means in the TM context. By sheer luck, you could be right, or you may be, as a lot of non-lawyers are, dead wrong about what's "similar" and what's "completely different."
Lawyers go to school for 3 years, get a degree, pass the bar exam (sometimes more than 1), practice for years, read innumerable cases about their practice, and have a MUCH better and subtle grasp of the governing law as applied to any given facts. Since you didn't do any of that, you ned to realize that need to hire professional help, because you're playing on our turf, and you don't know the rules of the game.
You acknowledge your products are similar, so the issues are 1) if their TM is even protectible, and 2) if so, whether your use infringes. Only a TM attorney is qualified to address those questions.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
It would be difficult to give you a suggested direction without specifics. Please feel free to send a confidential message.

Find an intellectual property attorneywho will give you a brief, no cost consult. This can be done on the phone. You basically have three options: 1) don't respond; 2) respond yourself (not recommended); and 3) engage an IP attorney who will work within your budget to respond appropriately. The response can take several forms ranging from a simple letter to a declaratory judgment action. A poorly constructed response may result in loss of rights or damaging unintended admissions. C&D letters are common: many of them are drafted poorly. In my experience a well written response can put an end to the matter, in many cases at least.
