# 🔬 Patent Application Services

Professionals who protect your inventions and ideas as “strong intellectual property rights”

**Patent attorneys with a deep understanding of technology help you secure the patent rights that protect your business**. Our   
technology-focused patent attorneys provide comprehensive support from research and development through to commercialization.

## What Is a Patent? — A 20-Year Right to Exclusively Exploit an Invention

A patent is the right to exclusively practice a new invention (a technical idea). It is a powerful right that allows you to prevent unauthorized use by third parties for up to 20 years from the filing date, and it is one of the most important forms of intellectual property for establishing a competitive advantage for your business.

**Benefits of a Patent**

✔ Legally prevent competitors from copying your invention

✔ Generate licensing revenue (royalties)

✔ Can be used to demonstrate technical capabilities to investors and business partners

✔ Provides an advantage in the review process for subsidies and grants

✔ Enhances corporate value during M&A or business sales

## Features of EVORIX’s Patent Application Service

🎯 1. Technical Understanding — Accurately Capturing the Essence of the Invention

EVORIX’s patent attorneys have backgrounds in a wide range of technical fields, including mechanical engineering, electrical engineering, software, chemistry, and biotechnology. Through dialogue with inventors, we delve deeply beyond superficial configurations to understand “why it is superior” and “where the essential inventive step lies,” enabling us to draft strong claims.

🔍 2. Thorough Prior Art Search

We assess the likelihood of patent grant through a pre-filing prior art search. Our patent attorneys, who are well-versed in the examination trends of the Patent Office, accurately identify the points of differentiation from similar technologies, thereby avoiding unnecessary filings and increasing the likelihood of obtaining patent protection.

📝 3. High-Quality Specification Drafting

A specification is not merely a technical document; it is a “contract” for asserting rights over a 20-year period. At EVORIX, we are committed to drafting specifications that secure a broad and strong scope of rights, with an eye toward future business expansion and potential litigation.

🛡 4. Handling of Post-Filing Procedures

We provide comprehensive support throughout the entire process—from drafting responses and amendments to notices of rejection to preparing for oral examinations—until registration is granted. Even with challenging cases, we never give up and secure patent rights through logical rebuttals.

🌍 5. International Applications (PCT)

We provide one-stop service for filing applications in countries around the world, including the U.S., Europe, China, South Korea, and Southeast Asia. Leveraging our network of local agents, we support the development of global intellectual property portfolios.
