More directly, it is a shortened version of the term letters patent, which was an open document or instrument issued by a monarch or government granting exclusive rights to a person, predating the modern patent system.
Similar grants included land patents, which were land grants by early state governments in the USA, and printing patents, a precursor of modern copyright.
In modern usage, the term patent usually refers to the right granted to anyone who invents any new, useful, and non-obvious process, machine, article of manufacture, or composition of matter.
Some other types of intellectual property rights are also called patents in some jurisdictions: industrial design rights are called design patents in the US, and utility models and Gebrauchsmuster are sometimes called petty patents or innovation patents.
These claims must meet relevant patentability requirements, such as novelty, usefulness, and non-obviousness.
The exclusive right granted to a patentee in most countries is the right to prevent others, or at least to try to prevent others, from commercially making, using, selling, importing, or distributing a patented invention without permission.By using WIPO’s statistical data, users agree not to republish or commercially re-sell any of the data.In addition, when employing WIPO’s statistical data in any written work, users must cite “WIPO Statistics Database” as the source of the data.Corrigan offers nationwide service and ships worldwide.Reliable intellectual property (IP) statistics are an important tool in understanding trends in policy, business, and technology worldwide.TRIPS also provides that the term of protection available should be a minimum of twenty years.
