Like any other property right, it may be sold, licensed, mortgagedassigned or transferred, given away, or simply abandoned. A patent, being an exclusionary right, does not necessarily give the patent owner the right to exploit the invention subject to the patent.

Patent law example, many inventions are improvements of prior inventions that may still be covered by someone else's patent. Some countries have "working provisions" that require the invention be exploited in the jurisdiction it covers.

Consequences of not working an invention vary from one country to another, ranging from revocation of the patent rights to the awarding of a compulsory license awarded by the courts to a party wishing to exploit a patented invention.

The patentee has the opportunity to challenge the revocation or license, but is usually required to provide evidence that the reasonable requirements of the public have been met by the working of invention.

Challenges[ edit ] In most jurisdictions, there are ways for third parties to challenge the validity of an allowed or issued patent at the national patent office; these are called opposition proceedings. It is also possible to challenge the validity of a patent in court.

A patent can be found invalid on grounds described in the relevant patent laws, which vary between countries. Often, the grounds are a subset of requirements for patentability in the relevant country. Although an infringer is generally free to rely on any available ground of invalidity such as a prior publicationfor examplesome countries have sanctions to prevent the same validity questions being relitigated.

An example is the UK Certificate of contested validity. It is common for companies engaged in complex technical fields to enter into multiple license agreements associated with the production of a single product.

Moreover, it is equally common for competitors in such fields to license patents to each other under cross-licensing agreements in order to share the benefits of using each other's patented inventions.

Ownership[ edit ] In most countries, both natural persons and corporate entities may apply for a patent. In the United States, however, only the inventor s may apply for a patent although it may be assigned to a corporate entity subsequently [26] and inventors may be required to assign inventions to their employers under an employment contract.

The inventors, their successors or their assignees become the proprietors of the patent when and if it is granted. If a patent is granted to more than one proprietor, the laws of the country in question and any agreement between the proprietors may affect the extent to which each proprietor can exploit the patent.
