The poetry of the Lanham Act

Yehuda, an Israeli blogger who blogs on board games and gaming, presents the Lanham Act in verse.  A taste:

If you own a mark that’s
Really used in commerce
Pay heed to the directions
Written down in this verse

You must “own” the trade-mark
(Though it doesn’t say how)
And you must promise to use it
Or be using it now

It is to weep.
