I'm planning to publish a book of hard sudoku problems, and I'll be including a quick rundown of advanced techniques. The puzzles will be generated by a program I wrote, and it will also spit out the steps taken to solve them. Here's the problem: We all know the X-wing technique by only one name, yet the name is trademarked. I want to cover my bases with a disclaimer.

This is what I'm thinking of going with:

X-wing is a trademark of Lucasfilm, Ltd. No infringement of any kind is intended. The term X-wing appears in this book as the only well-known name for a common sudoku solving technique. The use of this term does not imply any affiliation whatsoever with Lucasfilm, Ltd.

For anyone a little knowledgeable on the subject of legalese, how does that look?
