In March 2007, David Heinemeier Hansson filed three Ruby on Rails related trademark applications to the USPTO. These applications regard the phrase "RUBY ON RAILS", the word "RAILS",and the official Rails logo. As a consequence, in the summer of 2007, Hansson denied to Apress the permission to use the Ruby on Rails logo on the cover of a new Ruby on Rails book written by some authoritative community members. The episode gave rise to a polite protest in the Ruby on Rails community. In response to this criticism, Hansson replied: I only grant promotional use [of the Rails logo] for products I'm directly involved with. Such as books that I've been part of the development process for or conferences where I have a say in the execution. I would most definitely seek to enforce all the trademarks of Rails.

商标保护，很有必要的

Rails 不是 rails，应该是可以做为商标的

that's okay..别人的书上都不能用 Rails 的 Logo

有没有人看过《乐者为王》？这是一本关于 Linux 的作者，大神李纳斯·托沃兹的个人传记。 我记得在大学的时候看这本书，有一个桥段，有个商人骗取了 LInus 的信任和授权，然后把 Linux 的域名注册为己有，后来 Linux 基金会花了大量的时间和金钱，才通过法律手段将 Linux 商标和域名讨回来，并交付给 Linus 本人掌管，因为整个社区的人都认为，只有 Linus 本人拥有 Linux 商标才是对 Linux 商标最大的保护。
