Glossary & Links
The TIPAG Glossary is not legally binding.
This glossary explains key technical terms as they are used in the context of professional patent searches — such as those conducted by TIPAG. It helps developers, companies, and interested parties better understand the methods, document types, and evaluation steps involved, and clearly interpret the results of a patent search.
TIPAG
TIPAG is familiar with all of the terms and concepts mentioned below — and many more — and provides its clients with comprehensive support, drawing on over 30 years of experience in all aspects of the patent system.
AI and Internet Search
We’re all familiar with them — but we use them with the utmost care. After all, we don’t want a Google search or an AI prompt to suddenly become prior art. They are a useful tool for patent and prior art searches. We often use a closed database and our internal data, some of which dates back over 30 years.
Amendment
In patent law, an amendment (change or correction) refers to the modification of the patent application or the patent claims. It serves to respond to objections raised by examiners, to better distinguish the invention from the prior art, or to clarify the scope of protection:
- Response to examination notices: In most cases, an amendment is a response to an initial examination notice (office action) in which the patent office points out deficiencies or conflicting prior art.
- The subject matter of the patent application may not be subsequently expanded by an amendment.
- After the patent is granted, the scope of protection of the claims may no longer be expanded, but only narrowed.
Cease-and-Desist Letter
A cease-and-desist letter is a formal, extrajudicial demand addressed to an alleged patent infringer requiring the immediate cessation of the unauthorized use of a patented invention. Its purpose is to avoid costly litigation and typically requests the submission of a legally binding cease-and-desist declaration, often including contractual penalties for future violations.
The following claims may be asserted:
- Injunctive Relief:
A demand that the infringing activity be discontinued in the future, often reinforced by a cease-and-desist declaration subject to contractual penalties. - Right to Information:
An obligation to disclose the extent and duration of the patent infringement, including information such as quantities sold, revenues generated, and supplier details. - Claim for Damages:
A demand for financial compensation, which may be calculated based on lost profits, a hypothetical royalty fee, or the profits earned by the infringer.
A cease-and-desist letter is often accompanied by evidence of use (EoU) prepared by a patent engineer.
Claim
A patent claim defines the exact scope of protection for an invention. It specifies, in legally precise terms, exactly what is protected and what third parties are prohibited from manufacturing, using, or selling without permission.
A claim is usually an extremely long single sentence, often consisting of a preamble (the known prior art) and a defining portion (the actual inventive feature).
There are independent claims and dependent claims, which should be read as an extension of the independent claims.
Disclosure, Invention-Disclosure
An invention disclosure is a confidential document, typically prepared by a patent engineer in collaboration with the inventor. It comprehensively describes and, where necessary, further develops all aspects of an invention so that a patent attorney can directly prepare and file a patent application.
EoU (Evidence of Use)
An EoU (Evidence of Use) is a detailed analysis and documentation that demonstrates how an actual product, service, or technological process infringes upon or utilizes the features of an existing patent claim.
The report is usually presented in the form of a so-called EoU chart (also known as a claim chart).
All technical features of a protected patent (e.g., “component X with function Y”) are directly compared with the features of an actual competing product.
An EoU chart is also used as evidence in court during litigation.
EPO, European Patent Organisation
European Patent Office. It conducts a centralized grant procedure, which results in a bundle of national European patents.
FTO-Analysis
An FTO analysis (short for “Freedom to Operate”) is a legal and technical review. It ensures that a company can manufacture and market a new product or process without infringing on third-party patents or other intellectual property rights.
Litigation
Litigation (the term for legal disputes or legal proceedings) in patent law encompasses all legal disputes before courts or arbitration tribunals that revolve around the enforcement, defense, or invalidation of patents. These include:
- Infringement proceedings
- Nullity and opposition proceedings (validity)
Patent
A patent protects your technical invention. It allows you to prohibit competitors from commercially exploiting your invention for up to 20 years. In countries where the patent is valid, you determine who may manufacture, sell, or import your invention. You may also commercialize your patent by selling it or licensing others to use the invention.
Patent Attorney
A patent attorney advises and represents clients in matters relating to the protection of intellectual property, such as inventions, trademarks, and designs. They assess whether an invention is patentable, translate technical innovations into legally precise patent specifications, and represent clients before patent offices and other authorities. Patent attorneys often work together with patent engineers, who provide the required technical expertise in the form of reports, disclosures, patent studies, or Evidence of Use (EoU) analyses.
Patent Engineer
A patent engineer serves as the central link between technology and law. He analyzes new inventions, assesses their patentability, and works closely with inventors and patent attorneys. He also monitors the market and the competition. His in-depth engineering knowledge enables him to finalize “half-finished inventions” or make them patentable in the first place.
They conduct FTO (Freedom-to-Operate) analyses and evaluate potential workarounds (design-around).
In cases involving licensing claims, litigation, or patent amendments, they conduct the necessary clarifications and investigations. In doing so, they prepare patent studies, an EoU (Evidence of Use), or an infringement report. They also analyze actual devices.
Patent Licensing
A legal agreement in which the patent holder (licensor) grants another party (licensee) permission to use, manufacture, or sell the protected invention. In return, the licensee pays financial fees known as royalties. There are various types of licenses, which differ in scope and the rights granted:
- Exclusive license
- Non-exclusive license
- Cross-licensing: Two or more parties mutually exchange the rights to use their respective patents.
- Compulsory license (rare, ordered by a court or government)
Patent Search
A structured search of existing patents and publications to assess the eligibility of one’s own patent application or to avoid patent infringement.
Patent Study (Landscape Report)
A patent study (often referred to in English as a “patent landscape report”) is a systematic analysis of patent documents and technical expertise. It is used to evaluate innovations, identify technology trends, and minimize legal risks in a specific market. As part of this process, claim content is analyzed for vulnerability, inaccuracy, and reasonable interpretation, and is sometimes compared with existing products or prior art.
It can also be expanded to include the following areas:
- Freedom-to-Operate (FTO)
- Patent Mapping & Technology Trends: Visual and statistical analyses of global patent data.
- Competitive Analysis: Detailed monitoring of the patent activities of direct competitors.
- Due Diligence: Evaluation of a company’s patent portfolio that is to be acquired, sold, or merged to determine its actual value and potential risks.
Validity Study (Legal Validity Analysis): A targeted search for prior art to challenge or invalidate an opposing patent in the event of a dispute.
Portfolio Evaluation
Companies use EoUs and patent studies to assess the actual market value of their own patent portfolios and to prepare for potential negotiations. These valuations are usually supported by relevant patent studies or EoUs.
Prior Art (State of the Art)
Prior art refers to all knowledge and technology that was publicly available anywhere in the world prior to the filing date of a patent application. This includes:
- Published patents and patent applications
- Scientific publications
- Technical books
- White papers and studies
- Public presentations and lectures, conference papers, or trade shows
- Publicly available products and services
- Online content
Trademark
Legally, a trademark is a protected symbol that distinguishes a company’s products or services from those of other companies. In principle, any graphic representation of a symbol can be a trademark under the law, such as words, combinations of letters, numbers, graphic images, three-dimensional shapes, slogans, combinations of these elements, or even sound marks consisting of a sequence of sounds.
WIPO
World Intellectual Property Organization. Administers international patent applications, particularly under the Patent Cooperation Treaty (PCT), which allows applicants to seek protection in over 150 countries with a single international application.
