Water, Water Everywh | |
Ironically, the world’s most precious resource is also one of its most plentiful. More than three-quarters of the world is literally covered in water. Yet, only 1 percent of the world’s water supply is fit to drink. Ninety-seven percent is salt water, and 2 percent is frozen in glaciers or polar ice caps. | ||

The Patent Litigatio | |
Patent and copyright protection are included in the U.S. Constitution as a way to safeguard scientific and commercial innovations, as well as books, movies, music and other creative products. But, unlike laws protecting personal property, the copyright and patent laws are supposed to “promote the progress of science and useful arts.” | ||
