My initial reaction was to doubt the letter’s authenticity; but the blogpost at the link appears to be credible.
My next reaction was that such a letter (whether authentic or not) should be put on the wall of every IP attorney as a model. As I was taught as a junior litigator at Herbert Smith, the strongest legal letters are often the least aggressive. (I did a post about how awful litigation letters can be at The Lawyer in January.)
However, the recipient boasts that he will not be accepting the money to change the cover of the current print run and on the digital version. One wonders if a more robust letter would have had more immediate effect. Perhaps the letter was too polite in that regard?
Nonetheless, it is still very pleasant to see a litigation letter in such terms on an intellectual property matter. So if the letter is genuine, due credit and much respect to its author, Christy Susman, the “Senior Attorney – Trademarks” at Jack Daniel’s.
(But I do wish Americans would write “trade marks” correctly – it is two words…)
