As some of you may have heard, Google now lets us search patents issued in the US over the last 100 or so years. Fun stuff. Here are a few relevant to the sorts of conversations that go on around here:
Grammar Game (1947)
Game for teaching grammar (1994)
System and method for teaching writing using microanalysis of text (2000)
Device for teaching writing (1912)
Teaching method and apparatus (for expository writing, 1981)
Enjoy.
