If you're going to sue someone for taking your name, you should probably be sure they actually took your name.
The Quaker Oats Company thought they'd found a business in California using the company's trademarked name as the name of their Christmas tree farm. So they did what big corporations always do when they find some tiny business using a name like theirs: Send a letter from a lawyer telling them to quit it.
The only problem, as the respondent points out, is that the company is named Quaker Oaks Christmas Tree Farm after a wooded area used by Quakers for their worship meetings. The business is owned by Quakers -- more formally known as members of the Society of Friends. No response has been received yet from the company, although the folks of the Quaker Oaks have invited the lawyer sending the letter to visit them at any time and see for herself.
