Patent Infringement Under United States Law
In the United States, a patent provides its proprietor with the right to exclude others from utilizing the invention claimed in that patent. Should a person utilize that invention, without the permission of the patent proprietor, they may infringe that patent.
More specifically, an infringement may occur where the defendant has made, used, sold, offered to sell, or imported an infringing invention or its equivalent.
No infringement action may be started until the patent is issued. However, pre-grant protection is available under 35 U.S.C. ยง 154(d), which allows a patent owner to obtain reasonable royalty damages for certain infringing activities that occurred before patent's date of issuance. This right to obtain provisional damages requires a patent holder to show that (1) the infringing activities occurred after the publication of the patent application, (2) the patented claims are substantially identical to the claims in the published application, and (3) the infringer had "actual notice" of the published patent application.

“The cigar-box which the European calls a “lift” needs but to be compared with our elevators to be appreciated. The lift stops to reflect between floors. That is all right in a hearse, but not in elevators. The American elevator acts like the man’s patent purge—it works”

“God knows that any man who would seek the presidency of the United States is a fool for his pains. The burden is all but intolerable, and the things that I have to do are just as much as the human spirit can carry.”
—Woodrow Wilson (1856–1924)
“Perhaps anxious politicians may prove that only seventeen white men and five negroes were concerned in the late enterprise; but their very anxiety to prove this might suggest to themselves that all is not told. Why do they still dodge the truth? They are so anxious because of a dim consciousness of the fact, which they do not distinctly face, that at least a million of the free inhabitants of the United States would have rejoiced if it had succeeded. They at most only criticise the tactics.”
—Henry David Thoreau (1817–1862)
“Unless we maintain correctional institutions of such character that they create respect for law and government instead of breeding resentment and a desire for revenge, we are meeting lawlessness with stupidity and making a travesty of justice.”
—Mary B. Harris (1874–1957)
