Started watching this show called Sons Of Guns which is interesting and got me thinking about different types of legalities and all. One question I had was if a person invents something could the government take that patent/right away from that person saying it's a "Matter of National Security"? This being in a place like the US where individuals have a lot of freedoms.
Depends on what you make. Article 1 Section 8 of the United States of the Constitution gives Congress the ability "To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries." In other words, they are allowed to make laws regardin' patents due to this clause. Right now, the law is that your patent is safe for twenty years from the earliest filing date.
Assumin' the country is not at war and your invention is not obviously a "Matter of National Security" then the government cannot touch it. They might try and act cute by comin' with some bizarre scenario that makes it a threat, but they try to avoid lawsuits and bad PR.
Very relevant to the matter:
Organization by General Electric
On August 4, 1914, the United Kingdom and France declared war on Germany and Austria-Hungary, starting World War I. Radio traffic across the Atlantic Ocean increased dramatically after the Allies cut German cable telegraphs.
During the war, the United States Navy suppressed patents owned by the major companies involved with radio manufacture in the United States to facilitate the war effort. All production of radio equipment was allocated for the Army and Navy. The Navy sought to maintain a government monopoly of wireless radio; however, the wartime command system over radio was to eventually end by the tabling of the maintenance of government control by the U.S. Congress in 1918. The rejection of the government monopoly did not prevent the Navy from creating a national radio system.[3] On April 8, 1919, U.S. Navy Captain Stanford C. Hooper and Admiral W. H. G. Bullard met with General Electric executives to ask that they not sell their Alexanderson alternators to the British-owned Marconi Company and its subsidiary Marconi Wireless Telegraph Company of America. The premise of the Navy's proposal was that if GE created an American owned radio company, then the Navy would secure a commercial monopoly of long-distance radio communication. This marked the beginning of negotiations by which GE would buy American Marconi and organize what would become the Radio Corporation of America.[4]

Well, during war a government will often bypass its governin' documents in order to protect the country and get things down in short periods of time.
