FTO Terminology Glossary Overview

This FTO terminology glossary explains key patent-risk terms that product, legal, and business teams encounter. FTO analysis involves specialized terminology that can be confusing for those new to patent law and intellectual property. This glossary provides clear definitions of key FTO analysis terms, helping you understand the language used in FTO analysis reports, legal opinions, and patent discussions.

Core FTO Concepts

FTO search (FTO)

The legal right to develop, manufacture, market, and sell a product without infringing valid patents held by others. FTO analysis assesses whether a company can operate freely in a particular market without facing patent infringement claims.

FTO Analysis

A comprehensive legal and technical assessment of patent infringement risks associated with a product or technology. FTO analysis identifies patents that may be infringed by a product and evaluates the risk of patent infringement litigation.

Subject Technology

The specific product, technology, or business method that is the focus of FTO analysis. Subject Technology must be clearly defined to ensure comprehensive and accurate FTO analysis.

patent landscape search

The collection of patents relevant to a particular technology area or product. Patent landscape analysis identifies major patent holders, patent density, and emerging patent trends in a technology area.

Patent Searching and Analysis

Patent Search

A systematic process of identifying patents relevant to a particular technology or product. Patent searches use keywords, Classification Codes, and citation analysis to locate relevant patents in patent databases.

Prior Art

Previously published information, patents, or products that existed before a patent application was filed. Prior art is used to assess patent validity and novelty.

Patent Database

A searchable collection of patent documents maintained by patent offices or commercial providers. Major patent databases include USPTO, EPO, WIPO, and Google Patents.

Classification Code

A standardized framework for organizing patents by technology area. Major classification frameworks include IPC (International Patent Classification), CPC (Cooperative Patent Classification), and USPC (United States Patent Classification).

Citation Analysis

Analysis of patent citations to identify related patents and patent families. Forward citations identify patents that cite a particular patent; backward citations identify patents cited by a particular patent.

Patent Family

A group of patents covering the same invention filed in multiple countries. Patent families typically include the original patent and corresponding patents filed in other jurisdictions.

Claim Analysis

Patent Claim

A numbered statement in a patent that defines the scope of the invention. Patent claims are the most important part of a patent for determining infringement and validity.

Claim Element

A specific component or limitation of a patent claim. Claim charting involves mapping each claim element to product features.

Claim Scope

The breadth of a patent claim. Broad claims cover more products but are more vulnerable to invalidity challenges; narrow claims cover fewer products but are more likely to be valid.

Dependent Claim

A patent claim that references and narrows an independent claim. Dependent claims are narrower than independent claims and are more likely to be valid.

Independent Claim

A patent claim that stands alone and does not reference other claims. Independent claims are typically broader than dependent claims.

claim construction search

The process of interpreting patent claim language to determine the scope of the patent. Claim construction is critical for determining infringement and validity.

Claim Charting

A detailed analysis that maps each element of a patent claim to corresponding features of a product. Claim charting is used to assess literal infringement.

Element Extraction

The process of breaking down a patent claim into its individual elements or limitations. Element extraction is the first step in claim charting.

Infringement Analysis

Infringement

The unauthorized making, using, offering to sell, selling, or importing of a patented invention. Infringement can be literal or under the doctrine of equivalents.

Literal Infringement

Infringement that occurs when a product contains every element of a patent claim. Literal infringement is the most straightforward form of infringement.

Doctrine of Equivalents

A legal doctrine that finds infringement even when a product does not literally contain every element of a patent claim. Under the doctrine of equivalents, a product infringes if it performs substantially the same function in substantially the same way to achieve substantially the same result.

Willful Infringement

Infringement that occurs with knowledge of the patent and deliberate disregard for the patent rights. Willful infringement can result in enhanced damages (up to treble damages).

Infringement Opinion

A legal opinion from a patent attorney assessing whether a product infringes a particular patent. Infringement opinions are used to support business decisions and may be used in litigation.

Clearance Opinion

A legal opinion from a patent attorney assessing whether a product does not infringe any valid patents. Clearance opinions provide confidence in FTO and may reduce damages if litigation occurs.

Patent Validity

Patent Validity

The legal status of a patent. A valid patent is enforceable; an invalid patent is not enforceable.

Novelty

A requirement for patentability. An invention is novel if it is not disclosed in a single prior art reference.

Obviousness

A requirement for patentability. An invention is obvious if the differences between the invention and prior art would be obvious to a person skilled in the art.

Enablement

A requirement for patentability. A patent specification must enable a person skilled in the art to make and use the invention.

Written Description

A requirement for patentability. A patent specification must adequately describe the invention.

Indefiniteness

A ground for patent invalidity. A patent claim is indefinite if it does not clearly define the scope of the invention.

Validity Opinion

A legal opinion from a patent attorney assessing whether a patent is valid. Validity opinions assess novelty, obviousness, enablement, written description, and indefiniteness.

Validity Challenge

An attempt to invalidate a patent through administrative proceedings (e.g., inter partes review) or litigation.

Design-Around and Mitigation

Design-Around

A modification to a product design to avoid infringing a patent. Design-arounds are often the preferred mitigation strategy when feasible.

Design-Around Analysis

An assessment of whether a product can be modified to avoid infringing a patent. Design-around analysis considers feasibility, cost, and impact on product functionality.

Licensing

An agreement that grants permission to use a patented invention in exchange for payment. Licensing is an alternative to design-around when design modifications are not feasible.

Royalty

A payment made to a patent holder for the right to use a patented invention. Royalties can be fixed or variable (based on sales).

Mitigation Strategy

A plan to address patent infringement risk. Mitigation strategies include design-around, licensing, validity challenge, or risk acceptance.

Risk Assessment

Infringement Likelihood

The probability that a product infringes a patent. Infringement likelihood is assessed based on claim scope, product features, and claim interpretation.

Enforcement Likelihood

The probability that a patent holder will enforce a patent against a product. Enforcement likelihood is assessed based on patent holder identity, patent value, and competitive landscape.

Patent Validity Risk

The probability that a patent is invalid. Patent validity risk is assessed based on prior art, claim scope, and patent prosecution history.

Overall Risk

A combined assessment of infringement likelihood, enforcement likelihood, and patent validity. Overall risk is typically categorized as high, medium, or low.

Risk Tolerance

A company’s willingness to accept patent infringement risk. Risk tolerance varies by company, product, and market.

Risk Acceptance

A decision to proceed with a product despite identified patent infringement risk. Risk acceptance is typically documented and may include contingency planning.

Legal and Procedural Concepts

Attorney-Client Privilege

A legal privilege that protects communications between a client and attorney from disclosure. FTO analysis conducted by or at the direction of counsel is protected by attorney-client privilege.

Work Product Doctrine

A legal doctrine that protects materials prepared by counsel in anticipation of litigation from disclosure. FTO analysis may be protected as work product.

Privilege Waiver

The loss of attorney-client privilege through improper disclosure. Privilege waiver can occur if FTO analysis is disclosed to third parties without appropriate protections.

Patent Prosecution

The process of obtaining a patent from a patent office. Patent prosecution history is relevant to claim interpretation and validity assessment.

Patent Prosecution History Estoppel

A doctrine that limits claim interpretation based on statements made during patent prosecution. Patent prosecution history estoppel can narrow claim scope.

Inter Partes Review (IPR)

An administrative proceeding at the USPTO to challenge patent validity. IPR is an alternative to litigation for challenging patent validity.

Reexamination

An administrative proceeding at the USPTO to reconsider patent validity. Reexamination can be requested by patent holders or third parties.

Patent Types and Variations

Utility Patent

A patent that covers the functional aspects of an invention. Utility patents are the most common type of patent.

Design Patent

A patent that covers the ornamental design of an article of manufacture. Design patents protect the visual appearance of a product.

Plant Patent

A patent that covers a new plant variety. Plant patents are less common in FTO analysis.

Continuation Patent

A patent application that continues prosecution of an earlier patent application. Continuation patents can have different claim scope than the original patent.

Divisional Patent

A patent application that covers subject matter that was divided from an earlier patent application. Divisional patents can have different claim scope than the original patent.

Reissue Patent

A patent that is reissued to correct errors in an original patent. Reissue patents can have broader or narrower claim scope than the original patent.

International Patent Concepts

International Patent Classification (IPC)

A standardized framework for classifying patents internationally. IPC is used by patent offices worldwide.

Cooperative Patent Classification (CPC)

A standardized framework for classifying patents developed jointly by the USPTO and EPO. CPC is used by both offices.

Patent Cooperation Treaty (PCT)

An international treaty that provides a centralized filing framework for patent applications in multiple countries. PCT applications are filed with WIPO.

European Patent Office (EPO)

The patent office for European countries. EPO patents are enforceable in multiple European countries.

WIPO (World Intellectual Property Organization)

The United Nations agency responsible for administering international patent treaties. WIPO administers the PCT framework.

Unified Patent Court (UPC)

A new court framework in Europe for patent litigation. The UPC provides a centralized forum for patent disputes in multiple European countries.

Litigation and Enforcement

Patent Infringement Lawsuit

A civil lawsuit alleging that a defendant has infringed a patent. Patent infringement lawsuits seek damages and injunctive relief.

Cease-and-Desist Letter

A letter from a patent holder demanding that a company stop infringing a patent. Cease-and-desist letters often precede patent litigation.

Damages

Monetary compensation awarded in a patent infringement lawsuit. Damages can be actual damages or enhanced damages for willful infringement.

Enhanced Damages

Damages awarded in cases of willful infringement. Enhanced damages can be up to treble (three times) actual damages.

Injunction

A court order prohibiting a company from making, using, or selling a patented product. Injunctions can be preliminary (before trial) or permanent (after trial).

Preliminary Injunction

A temporary court order prohibiting a company from infringing a patent pending trial. Preliminary injunctions are difficult to obtain.

Permanent Injunction

A court order prohibiting a company from infringing a patent after a finding of infringement. Permanent injunctions are common in patent cases.

Non-Practicing Entity (NPE)

A company that owns patents but does not manufacture products. NPEs are often called “patent trolls” and are known for aggressive enforcement.

Patent Troll

A derogatory term for an NPE that acquires patents for the purpose of licensing or litigation. Patent trolls are often viewed negatively by the business community.

Documentation and Process

FTO Analysis Report

A comprehensive document summarizing FTO analysis findings, conclusions, and recommendations. FTO analysis reports are used to support business decisions and may be used in litigation.

Claim Chart

A detailed document mapping patent claim elements to product features. Claim charts are used to assess infringement and support litigation.

Search Strategy

A documented plan for conducting patent searches. Search strategies identify search terms, databases, and classification codes to be used.

Screening Criteria

Documented criteria for determining which patents warrant detailed analysis. Screening criteria help prioritize analysis efforts.

Risk Assessment Matrix

A table or matrix that categorizes patents by infringement likelihood, validity, and enforcement likelihood. Risk assessment matrices help prioritize mitigation efforts.

Decision Record

A documented record of FTO analysis decisions and the rationale for those decisions. Decision records support business decisions and may be used in litigation.
