A61P

SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS

Introduced: January 2000

Classification Context

Section:
HUMAN NECESSITIES
Class:
MEDICAL OR VETERINARY SCIENCE; HYGIENE
Subclass:
SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS

Description

A61P classifies chemical compounds and medicinal preparations according to their specific therapeutic effects and clinical applications in human and veterinary medicine. This subclass encompasses pharmaceuticals organized by disease or condition treated, such as agents for cardiovascular, respiratory, gastrointestinal, or neurological disorders, rather than by chemical structure or manufacturing process. Inventions in this category include active pharmaceutical ingredients, drug formulations, and combination therapies where the therapeutic target or indication is the primary classification criterion. Note that this class complements A61K (preparations for medical purposes), which focuses on formulation aspects and composition, whereas A61P emphasizes the therapeutic purpose and biological activity of the preparation.

Filing statistics

IPC subclass A61P recorded 1,178,026 patent applications worldwide between 2013 and 2023. Annual filings grew from 87,753 in 2013 to 99,310 in 2023 (+13%), peaking at 118,515 applications in 2021. The most active applicants in class A61 are PHILIPS ELECTRONICS (18,523 applications), NOVARTIS (14,253 applications) and COVIDIEN (13,953 applications).
