Thanks Spielman.
"I would focus heavily on the long term use and minimal LOC."
I'm guessing you mean to minimize talking about the LOC, since that would be a losing point for us (here, not much question about LOC). I agree. I was going to say nothing about LOC in my response.
"With that said, proof of senior user stauts is important in our response letters, if that proof is very convincing. Incorporation documents may be helpful, if the copr name is similar or same to the mark."
Here, the Incorp documents are identical to the mark. And, the client saved not only bank statememtns and canceled checks, but business receipts with services performed as well. Now, in this situation, I do understand that Fed TM Holder may come back and say "well, that was our 'at least as early as' date, and we were actually using it <some date preceding ours>"
That is why I was considering mentioning the latches/estopple from enforcement argument here -and why I saw Incorporation as somewhat important, as policing searches should have identified a business that was incorporating, or perhaps from the other side of the coin, that since client incorporated with the State prior to the other party claimed use of the mark, the State Database should have placed client on the RADAR of other company (and evential Fed TM Registrant).
"As far as the interplay of waiting to provide evidence or just providing it up front, it all depends upon the strength of the evidence and the percieved agressiveness of the potnetial Plaintiff."
Regarding the evidence of use, it seems to me to be strong (as long as it is not fabricated- and I have NOT even an inkling of a reason to believe it is fabricated). Aggressiveness of the Plaintiff. Probably 'avg. agreesiveness- not overly or undrly. In fact, the attorney signing the letter doesn't appear to practce in Trademarks (at least that is not in the atorney's areas of practice that I found).
"Lastly, after responding to the letter, if there is a long time failure to pursue the infringment action, i would view it as better to make the laches argument. "
Agreed. I was considering to responding that "We are Sr. User" and "Besides, you failed to police your mark" (well, maybe not exactly in those words). So would you include a receipt for services showing Sr. Status with the response, or wait until it is requested?
Thanks again, Spielman, and also interested if others have input as well...
