Ralph Lauren, the core designer and owner of the sportswear and fragrance line Polo Ralph Lauren of the Ralph Lauren Corporation, filed his first lawsuit against U.S. Polo Association, the governing body of the game of polo in the U.S., in 1984 on claims of trademark infringement. A series of lawsuits has since then been filed. USPA filed countersuits but the court had always ruled in favor of Ralph Lauren until a 2014 dismissal of Lauren's lawsuit.

A holder of a federal reserve note has no right to demand an asset such as gold or silver from the government in exchange for a note. Consequently, some proponents of the intrinsic theory of value believe that the near-zero marginal cost of production of the current fiat dollar detracts from its attractiveness as a medium of exchange and store of value because a fiat currency without a marginal cost of production is easier to debase via overproduction and the subsequent inflation of the money supply.

Depending on market conditions, the cow may be bred with a ``dairy bull'' or a ``beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.
