Seems to be much better description about the case than the original article.

Excerpts from the article:

- Apple already owns two iPhone trademarks in Mexico in Class 9 and Class 28

- in 2009, Apple's lawyers decided iFone's Mexican Class 38 mark wasn't being actively used, and they filed a lawsuit to try and get it canceled so they could register their own pending Class 38 mark on "iPhone."

- iFone obviously disagreed and convinced the Mexican courts that they were still using the mark in commerce

  Class 9 = computers, software, cameras, and mobile phone
  class 28 = electronic game devices
  Class 38 = communication services
