Over the weekend, Dwight Silverman asked: “Does Microsoft know there’s already a Windows Defender out there?” I answered hypothetically:
Microsoft has an army of lawyers, and one would have to assume that no product naming decision gets publicly announced until there’s been a thorough trademark search.
Todd Bishop of the Seattle P-I says that assumption was right. He tracked down the developer of the original Windows Defender program, 22-year-old Adam Lyttle from Adelaide, Australia:
Lyttle wasn’t inclined to get into a legal tussle with the software giant and its army of lawyers. For one thing, he had stopped working on his Windows Defender program nearly a year before that point.
He was puzzled by one element of the agreement, which gives to Microsoft all rights to the Windows Defender name. However, after consulting with a friend in law school, he decided to just sign it and move on.
The story doesn’t make Microsoft look very good.
Thanks for following up, Todd!
