>> > just happened to think of a decent name for a calendar app a few >> weeks >> > ago: Timeline One would do well to search the US Patent and Trademark database before committing to any specific names. The trademark might be registered in some other country, but there is a good chance that whereever it is registered, it's also registered in the US, being the Microsoft of Nations and all. A certain well-known search firm failed to do due diligence before naming its popular webmail application "GMail". It turns out that "Gmail" was already a registered trademark in Germany. There was a lawsuit, which Google naively assumed they could win because of their own massive PageRank. They didn't. http://www.uspto.gov/ Note that one is permitted to use a mark that someone else owns, provided that the two marks don't conflict. I'm no IP attorney, so I won't pretend to explain just when one can use someone else's mark, but I will point out that the Supreme Court of Canada held that one can call any business "McDonalds" provided it doesn't sell hamburgers. I'll send you my bill in the mail. Mike -- Michael David Crawford mdcrawford at gmail dot com GoingWare's Bag of Programming Tricks http://www.goingware.com/tips/
