The primary purpose of patent examination is to determine whether the claimed invention is novel (new) and non-obvious (not evident to a person skilled in the art). This assessment is crucial to ensure that only genuine and innovative inventions are granted patents.

Commercial success is not a requirement for obtaining a patent. The primary criteria for patentability are novelty, non-obviousness, and utility. Commercial success may be a factor considered in assessing the value of a patent, but it is not a legal requirement.

In the United States, a utility patent has a term of 20 years from the date of filing the patent application. This period provides the patent holder with exclusive rights to make, use, sell, and license the patented invention.

The primary role of the patent examiner is to conduct a thorough search for prior art (existing knowledge and technology) relevant to the claimed invention. This search helps determine whether the invention is novel and non-obvious.

The purpose of a patent prosecution is to prepare and file a patent application with the relevant patent office. This involves drafting the patent claims, providing a detailed description of the invention, and submitting the necessary fees and documents.

In most jurisdictions that follow the first-to-file principle, the first person or entity to file a patent application for an invention is granted priority, even if someone else invented it earlier. This principle encourages prompt filing of patent applications to secure patent rights.

The purpose of a patent claim is to define the scope of the patent protection granted to the inventor. It precisely describes the invention and its essential features, thereby determining the boundaries of the patent holder's exclusive rights.

A provisional patent application provides temporary protection for an invention while allowing the inventor more time to develop and refine the invention before filing a non-provisional application. A provisional application is less detailed and has a shorter filing deadline than a non-provisional application. Additionally, a provisional application can be converted into a non-provisional application, but not vice versa.

The Patent Trial and Appeal Board (PTAB) is an administrative tribunal within the United States Patent and Trademark Office (USPTO). Its primary role is to review and decide appeals from patent examiners' decisions regarding the grant or denial of patents. The PTAB also conducts inter partes reviews (IPRs) and post-grant reviews (PGRs), which are proceedings to challenge the validity of issued patents.

A patent infringement lawsuit aims to determine whether a patent has been infringed, enforce the rights of the patent holder, and seek compensation for damages caused by the infringement. The lawsuit seeks to protect the patent holder's exclusive rights and prevent unauthorized use of the patented invention.

The doctrine of equivalents in patent law allows for minor variations of a patented invention to be considered infringements, even if they are not literally covered by the patent claims. This doctrine prevents infringers from making minor changes to the patented invention to avoid infringement.

The purpose of a patent maintenance fee is to cover the administrative costs incurred by the patent office in maintaining the patent. These fees are typically due at regular intervals throughout the life of the patent.

The Paris Convention for the Protection of Industrial Property is a landmark international treaty that establishes a system for international patent filing and priority. It allows inventors to file a single patent application in one country and claim priority in other countries that are party to the convention.

The World Intellectual Property Organization (WIPO) is a specialized agency of the United Nations that plays a vital role in patent matters. It administers international patent treaties and agreements, provides technical assistance and training to developing countries, and promotes international cooperation and collaboration in the field of patents.

A patent protects inventions, while a trademark protects brands and symbols. A patent has a longer duration than a trademark. A patent is granted by the government, while a trademark is registered with a trademark office.
