Understanding Boolean Logic: Its Definition and Legal Applications

Definition & Meaning

Boolean logic is a system of reasoning that uses specific operators to express relationships in logical arguments. The primary operators are "and," "or," and "not." This method is named after George Boole, a British-born Irish mathematician who laid the groundwork for this logical framework. In legal contexts, particularly in patent law, Boolean logic is used in search systems to refine and combine search queries effectively.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A patent attorney searching for documents related to renewable energy might use a query like "solar and (panel or cell) not (battery)." This search will return documents that include both "solar" and either "panel" or "cell," excluding any that mention "battery."

Example 2: A legal researcher could use a search string such as "contract or agreement not (void or invalid)" to find relevant contracts while excluding those that are void or invalid.
