What the WIPO DL-101 and DL-170 Certificates Actually Teach You

An engineer's notes on completing the WIPO Academy's General Course on Intellectual Property (DL-101, v2) and the Specialized Course on the Essentials of Patents (DL-170)

Author: Nguyễn Thành Đức — Founder, Nexus Sentire Technology · Contact: ngtduc693@gmail.com

Key Takeaways

DL-101 is WIPO Academy's certificate, self-paced General Course on Intellectual Property (Version 2). It is built as a foundation course covering copyright and related rights, patents, trademarks, industrial designs, geographical indications, plant variety protection, traditional knowledge, unfair competition, and the international treaty systems that connect them.
DL-170 is the Specialized Course on the Essentials of Patents
— a focused, self-paced course that goes deeper into patentability requirements, the patent application lifecycle, patent claims, and the economic role of patents.
Both courses are offered by the WIPO Academy, the training arm of the World Intellectual Property Organization, a specialized agency of the United Nations.
Both are self-paced, free of charge, tutor-supported, and end in a time-bound, multiple-choice online exam; passing awards an official electronic certificate of completion.
WIPO recommends completing DL-101 before moving on to patent-specific courses like DL-170, since DL-101 establishes the vocabulary and legal framework that DL-170 builds on.
I completed both courses while actively working as an engineer with pending patent and utility-solution applications at the Vietnam Intellectual Property Office — so this write-up blends what the courses teach with how that knowledge maps onto real filings.

Who Is Writing This

I'm Nguyễn Thành Đức, founder of Nexus Sentire Technology, a software and hardware engineer working mostly in .NET, AI systems, and connected devices. Alongside product work, I've filed three patent and utility-solution applications with the Vietnam Intellectual Property Office (two of which have already passed formal examination), spoken on AI and automation topics at universities including FPT University and VKU, and been recognized by DigitalOcean as a Hacktoberfest Super Contributor for open-source work.

Filing real patent applications is what pushed me toward WIPO's own training material — I wanted the formal, internationally recognized framework behind the process I was already doing by trial and error with local counsel. That's the lens this article is written through.

What Are DL-101 and DL-170, Exactly?

Both courses belong to the WIPO Academy's Distance Learning (DL) Program, which has been running since 1999 and offers online IP training in more than ten languages, ranging from free self-paced primers to tutor-led advanced and specialized courses.

	DL-101	DL-170
Full name	General Course on Intellectual Property (Version 2)	Specialized Course on the Essentials of Patents
Scope	Broad overview of the entire IP system	Focused deep-dive into patents specifically
Prerequisite	Builds on DL-001 (Primer on IP); recommended as the entry point	DL-101 recommended beforehand
Structure	Multiple self-paced modules with end-of-module self-assessments	Self-paced modules on patentability, filing, and economic impact
Exam	Time-bound, multiple-choice, online final exam	Time-bound, multiple-choice, online final exam
Certificate	Electronic certificate of completion on passing	Electronic certificate of completion on passing
Cost	Free of charge	Free of charge
Languages	Offered in the six UN languages plus Portuguese	Offered in Arabic, English, French, Portuguese, Russian, and Spanish

In short: DL-101 answers "what is IP and how does the system fit together," while DL-170 answers "how does a patent specifically get examined, granted, and enforced."

Part 1 — What I Learned From DL-101 (General Course on Intellectual Property, v2)

DL-101 is structured as a sequence of self-contained modules, each followed by a self-assessment quiz, with tutor support available throughout. It has been taken by hundreds of thousands of participants worldwide since 2001 and has been adapted by multiple WIPO member states for local audiences, which says something about how widely it's used as a baseline IP course in universities and IP offices alike.

Part 2 — What I Learned From DL-170 (Specialized Course on the Essentials of Patents)

DL-170 narrows the focus to patents and is positioned within WIPO's patent-track curriculum, alongside courses like the introduction to the Patent Cooperation Treaty (DL-101-PCT) and the e-Tutorial on Using Patent Information (DL-177). Where DL-101 gives one general module on patents, DL-170 expands that into a full course covering the basic principles and economic impact of patents, patentability, and enforcement.

Part 3 — Study and Exam Experience

A few practical notes for anyone planning to take DL-101 and/or DL-170.

Seeking Guidance on the Microsoft Elevate Educator Expert Pathway

Duc Nguyen Thanh — Tue, 12 May 2026 02:05:19 +0000

I’m currently exploring the pathway toward becoming a Microsoft Elevate Educator Expert for 2026, and I would genuinely appreciate insights from educators and community members who have experience with the program.

My background is primarily in software engineering, AI, cloud technologies, and developer community leadership. Alongside teaching at FPT Schools Hue (Vietnam), I actively work on bridging real-world engineering practices with classroom learning.

Over the past few years, I’ve been focusing on:

Teaching AI, Azure, DevOps, and Prompt Engineering to students and developers
Integrating Azure AI services into learning activities and practical projects
Mentoring students and participating in educational initiatives
Building real-world applications using Microsoft technologies such as Azure OpenAI, Semantic Kernel, ASP.NET Core, Blazor, and Power Platform
Contributing to the global developer community through technical writing, workshops, and mentorship

I’m also a global moderator at DEV Community and was fortunate to be ranked among the Top 3 .NET technical writers globally in 2024.

What I’m particularly interested in learning is:

How Microsoft evaluates measurable educational impact for the Expert pathway
How educators effectively demonstrate classroom innovation with AI
Best practices for aligning teaching approaches with Microsoft’s vision for responsible AI and modern learning ecosystems
What kinds of portfolios, evidence, or initiatives tend to stand out

One of my main goals is helping students move beyond theory and build practical AI/cloud solutions that reflect real industry scenarios.

If you are part of the Microsoft Educator ecosystem — or have gone through the journey yourself. I would truly appreciate any guidance, experiences, or recommendations you can share.

🤖 The Super Contributor Ascent: Code, Commitment, and the Chronicle of 13 Days

Duc Nguyen Thanh — Mon, 13 Oct 2025 11:04:42 +0000

This is a submission for the 2025 Hacktoberfest Writing Challenge: Contribution Chronicles

Last year, I completed Hacktoberfest by DigitalOcean at Level 4/4, proudly earning the Contributor badge

This year, DigitalOcean raised the bar - introducing Level SUPER, and after just 13 days, I reached Level Max – Super Contributor, ranking among the top 1500 participants worldwide! 👕🔥

This achievement is more than a metric of speed; it is the culmination of a persistent philosophy: Open Source is not just code sharing, it is knowledge sharing.

⚙️ The Challenge

My contribution was not about adding easily implemented features; it was about deep code sanitation and architectural refinement. The hours were spent not typing new lines, but in brain-aching code review a critical task I chose to tackle. This involved:

1. The Bug Hunt: Systematically identifying and rectifying nasty, subtle bugs and critical edge-case flaws hidden within complex algorithms. For instance, my work focused on refining the robustness of existing logic, ensuring that fundamental C# algorithm implementations were impervious to common boundary condition failures.
2. Performance Overhaul: Optimizing the integrity and efficiency of high-usage algorithms. My goal was to elevate the standard of the repository, guaranteeing that every C# implementation was not only functional but also performance-tuned and aligned with modern best practices.
3. Documentation & Clarity: Enhancing code clarity and documentation so that the repository serves as a superior educational resource for future developers learning C#.

These contributions, often overlooked when counting simple lines of code, are the most valuable to a project's long-term health. They represent the grueling, behind-the-scenes effort that fortifies the codebase against failure and improves the quality of knowledge being shared.

The Takeaway: Beyond the Merge

Participating in the 2024 Hacktoberfest and achieving Super status, reaffirmed my belief in the power of collective effort.

This challenge was a decisive lesson in persistence over perfection. Tackling a bug that has evaded others for months requires a specific kind of developer resilience. By diving deep into the internals of algorithmic implementations, I exponentially expanded my mastery of C# language features and software architecture patterns.

For me, being a Super Contributor means sharing not just my source code, but my insight, rigor, and passion for building a global, robust, and reliable technological foundation. The thrill of the 'Super' tier is the validation that focused, high-quality commitment is recognized and valued by the global open source community.

I look forward to continuing this chronicle, striving to make open source better, one critically-reviewed PR at a time. The ascent to Super is complete, but the contribution never ends.

Hey there, buddy!
Ever dreamed of having your own chatbot that can take food orders faster than you can say "cheeseburger with extra pickles"?
Well, buckle up because I’m about to show you how to get a fully functional food-ordering bot up and running in just 30 minutes!

Let’s go! 🍟

What You’ll Get Out of This

By the end of this guide, you’ll have a chatbot that can handle these three tasty scenarios:

Ordering something straight from the menu (like a cheeseburger combo—yum!).
Asking for the menu but ordering something that’s not there (sorry, no sushi here, but the bot will help you out!).
Canceling an order and starting fresh (because sometimes you change your mind mid-order). Ready? Let’s roll! 🚀

Step 1: Clone the DineBot Repo (5 Minutes)

First things first, let’s grab my project from GitHub.
I’ve already done the heavy lifting for you, so all you need to do is clone my repo

git clone https://github.com/ngtduc693/DineBot.git
cd DineBot

Make sure you’ve got .NET 10.0 SDK installed. This bot is built with .NET 10, so it’s a must-have

Step 2: Test Your Bot with Bot Framework Emulator (10 Minutes)

Let’s get this bot chatting using the Bot Framework Emulator—a super handy tool to test bots locally. It’s like having a mini restaurant right on your laptop!

Install the Emulator: Download the Bot Framework Emulator here. Pick the latest version for your OS (Windows, Mac, or Linux).
Install it and fire it up. It’s as easy as installing a game—click, click, done!

Back in your terminal, inside the DineBot folder, run:

dotnet run

You’ll see some magic happen in the terminal, and the bot will start listening at http://localhost:3978/api/messages. Keep this URL handy—it’s where your bot lives!

Connect the Emulator to Your Bot: Open Bot Framework Emulator and click Open Bot then paste the URL: http://localhost:3978/api/messages

Step 3: Let’s Chat and deploy to Azure AI Services (15 Minutes)

Upload the training model from TrainingModel here then deploy it to Azure Language Understanding

Update appsettings.json with your Azure Language Understanding credentials:

"LanguageUnderstanding": {
    "Endpoint": "",
    "Key": "",
    "ProjectName": "Food",
    "DeploymentName": ""
  }

OK! Let's chat

Scenario 1: Ordering Something on the Menu
Scenario 2: Asking for the Menu but Ordering Something Not Available
Scenario 3: Canceling an Order and Starting Fresh
