Basic Terminology in Patent Law
Understanding patent law requires familiarity with specific terminology. Below are some essential terms that form the foundation of patent law.
1. Patent
A patent is a legal document granted by a governmental authority that gives the inventor exclusive rights to their invention for a specified period, typically 20 years from the filing date.
2. Intellectual Property (IP)
Intellectual Property refers to creations of the mind, such as inventions, literary and artistic works, designs, symbols, names, and images used in commerce. Patents are a type of intellectual property.
3. Invention
An invention is a novel and non-obvious idea or method that provides a solution to a specific problem. To be patentable, an invention must meet certain criteria, such as novelty and usefulness.
4. Patent Claims
Patent claims define the boundaries of protection provided by the patent. They specify what the inventor claims as their invention and can include independent and dependent claims.
Example of Patent Claims
1. A method for treating disease X comprising administering compound Y to a patient.
2. The method of claim 1, wherein compound Y is administered in an amount effective to treat disease X.
5. Prior Art
Prior art refers to all existing knowledge, including patents, publications, and public knowledge, that is relevant to an invention's originality. It can impact the patentability of an invention.
6. Novelty
Novelty is a fundamental requirement for patentability, meaning the invention must be new and not previously disclosed to the public. An invention is considered novel if it has not been part of the prior art.
7. Non-Obviousness
Non-obviousness is another key requirement for patentability. It means that the invention cannot be obvious to a person skilled in the relevant field based on prior art. This is often assessed through a combination of existing knowledge.
8. Utility
Utility requires that the invention must have a specific, substantial, and credible utility. This means that the invention should be useful for its intended purpose.
9. Patent Examination
Patent examination is the process by which a patent office reviews a patent application to determine whether it meets the legal requirements for patentability.
10. Office Action
An Office Action is a communication from the patent office during the examination process. It may include objections or rejections, providing the applicant an opportunity to respond.
Process of Patent Examination
11. Provisional Patent Application
A Provisional Patent Application is a temporary filing that establishes an early filing date and allows the inventor to use the term "patent pending." It is not examined and does not mature into a patent unless a non-provisional application is filed.
12. Non-Provisional Patent Application
A Non-Provisional Patent Application is a formal request for a patent that is examined by the patent office. It must include claims and is subject to the full patent examination process.
13. Patent Issued
Once a patent application is examined and found to meet the necessary criteria, a patent is issued, granting the inventor exclusive rights to their invention.
14. Patent Infringement
Patent infringement occurs when someone makes, uses, sells, or distributes a patented invention without permission from the patent holder. This can lead to legal disputes.

15. Defenses Against Patent Infringement
Defenses against patent infringement are legal reasons for which an alleged infringer may avoid liability. Common defenses include:
- Invalidity: Claiming that the patent is not valid due to reasons such as lack of novelty.
- Non-infringement: Arguing that the accused product or process does not fall within the scope of the patent claims.
- License: Demonstrating that the use of the patented invention was authorized by a license.
16. Patent Litigation
Patent litigation is the legal process by which a patent holder enforces their rights against alleged infringers. This process can involve several stages:
Steps in Patent Litigation
17. Jurisdiction and Venue
Jurisdiction refers to the authority of a court to hear a case, while venue pertains to the specific location where a lawsuit can be filed. In patent cases, jurisdiction typically lies in federal courts, and venue can often be established in districts where the defendant resides or where the infringement occurred.
18. Pre-Trial Procedures
Before a patent case goes to trial, various pre-trial procedures are conducted, including:
- Initial Disclosures: Each party must disclose certain information relevant to the case.
- Motions: Parties may file motions to resolve certain issues before trial.
19. Discovery Phase
The discovery phase is a crucial part of patent litigation where both parties exchange evidence. This can include:
- Document Requests: Requests for relevant documents from the opposing party.
- Depositions: Sworn statements taken from witnesses or parties involved.
20. Trial and Post-Trial Procedures
During the trial, both parties present their cases, and evidence is examined. After the trial, several post-trial procedures may occur, such as:
- Judgment: The court issues its decision based on the trial.
- Appeals: The losing party may appeal the decision to a higher court.
21. Settlement and Alternative Dispute Resolution
Many patent disputes are resolved through settlement or alternative dispute resolution (ADR) methods, such as mediation or arbitration, to avoid the costs and uncertainties of litigation.
22. Patent Licensing
Patent licensing is the process by which a patent holder allows another party to use their patented invention, typically in exchange for royalty payments. Licensing agreements can vary widely in terms.
Types of Patent Licenses
- Exclusive License: Only the licensee can use the patent, and the patent holder cannot use it.
- Non-Exclusive License: The patent holder can license the patent to multiple parties.
23. Monetizing Patents
Monetizing patents involves generating revenue from patent rights, either through licensing agreements or selling the patents outright. Effective monetization strategies depend on the strength and market relevance of the patents.
24. Ethical Issues in Patent Practice
Patent practitioners must navigate various ethical considerations, including:
- Conflicts of Interest: Ensuring that representation of clients does not conflict with the interests of other clients.
- Client Confidentiality: Maintaining the confidentiality of client information.
- Duty of Candor and Good Faith: Obligating practitioners to act honestly and disclose relevant information to the patent office.
