Computer-Implemented Invention (CII)
An invention that is at least partially carried out by a computer, often involving method and system claims, particularly in software patents.

Continuation Application

Information Disclosure Statement (IDS)
A submission to the USPTO that lists prior art known to the applicant that may be relevant to the examination of a U.S. patent application.

Inventive Step / Non-obviousness

Locarno Classification
An international system for classifying industrial designs into categories for examination and indexing purposes.

Method Claim
A type of patent claim that protects a specific process or series of steps performed by a user, device, or system. Common in software and medical technologies.

Non-Provisional Application
A formal U.S. patent application that includes claims and is examined for patentability. It can lead to a granted utility patent.

Novelty

Office Action
An official letter from the examiner during the prosecution of a patent application, stating rejections or objections. The applicant must respond to keep the application active.

Ornamental Design
The visual, aesthetic aspect of a product that is protected by a design patent. It must be non-functional.

Patent Prosecution
The process of interacting with the patent office to secure the grant of a patent, including responding to office actions and amending claims.

Patentability
The criteria an invention must meet to be granted a patent, including novelty, inventive step, and industrial applicability.

Priority Date
The date from which the novelty of an invention is assessed. Often established by the earliest filed application in a patent family.

Prior Art
All publicly available knowledge before the filing date that may affect the novelty or obviousness of a claimed invention. Includes patents, publications, and publicly used products.

Provisional Application
A temporary U.S. filing that allows inventors to secure a priority date for up to 12 months before filing a formal non-provisional application.

Publication
Patent applications are typically published 18 months after the earliest priority date, making the invention publicly accessible.

Registered Community Design (RCD)
A European Union-wide design right that protects the appearance of a product, granted by the EUIPO for up to 25 years.

Specification
The part of the patent application that describes the invention in detail. It supports the claims and includes the background, summary, and embodiments.

Surface Shading
Used in design patent drawings to show depth and contours of the object. It helps clarify the visual aspects of the claimed design.

System Claim
A type of patent claim that protects a group of physical or logical components that operate together to perform a function. Often used in computing and telecommunications.

Total Visual Disclosure

WIPO (World Intellectual Property Organization)
A United Nations agency responsible for international IP services, including the PCT and Hague design systems.
