If you had walked into the Imperial Patent Office in Berlin on a cold morning in January 1886, you would have seen a nervous Karl Benz standing at the counter with a stack of papers in his hand. He wasn’t a wealthy industrialist. He wasn’t yet the founder of a global brand. He was simply an engineer with a dream so strange for its time that many dismissed it as fantasy.
What he submitted that day, Patent No. DRP 37435, titled “Vehicle with gas engine”, would quietly become the birth certificate of the modern automobile industry.
This is the story of how one man’s invention, persistence, and strategic use of intellectual property sparked a worldwide revolution, and what today’s innovators and entrepreneurs can learn from it.
1. The Engine-Driven Dream: How Karl Benz Began
Karl Benz grew up in Germany in the mid-19th century, a time when steam engines were powering locomotives, ships, and factory machines. Yet transportation on the streets was still ruled by horses, carriages, and the limits of muscle power. Benz believed something fundamentally different was possible, a personal vehicle driven not by steam or animals, but by a compact internal combustion engine.
The idea was bold. No one had imagined a lightweight engine powerful enough to move a vehicle reliably. No one had imagined roads filled with self-driven machines. And no one had imagined a time when individuals, not just companies or governments, would own motorised vehicles.
But Benz wasn’t imagining abstract possibilities. He was building them.
Working from a small workshop in Mannheim, he designed and developed a single-cylinder, four-stroke engine, and then did something revolutionary: he built the vehicle around the engine, making the two inseparable.
What he created in 1885 looked unlike anything the world had seen, a three-wheeled vehicle with wire-spoked wheels, tubular steel frame, chain drive, and a compact engine mounted horizontally at the rear. He called it the Patent-Motorwagen.
The invention was ready. The road ahead, however, wasn’t.
2. The Road to Reality: Trials, Failures & Persistence
For all its brilliance, the Motorwagen didn’t immediately inspire confidence. In fact, it crashed during one of the earliest public demonstrations. Startled onlookers assumed the machine was dangerous. Officials were skeptical. Investors weren’t lining up to fund a “road locomotive”.
Even the idea of a “car” sounded absurd.
Fuel wasn’t available in shops (Benz had to buy ligroin from pharmacies). Roads were uneven, muddy, and not designed for wheeled engines. There were no mechanics, no filling stations, no spare parts, no rules, nothing resembling an ecosystem.
And yet Benz persisted.
He improved his engine, refined the chassis, worked on stability, and tested the machine again and again.
But the biggest turning point came not from the engineer himself, but from someone who believed in him more deeply than anyone else, his wife, Bertha Benz.
Bertha Benz and the First Long-Distance Drive
In August 1888, without informing her husband, Bertha took the Motorwagen and embarked on a 100-kilometre journey from Mannheim to Pforzheim with her two teenage sons.
It was part test, part promotion, part rebellion, and entirely ingenious. Along the way she:
Bought fuel from pharmacies
Repaired a broken chain using a cobbler
Cleaned a clogged fuel pipe with her hairpin
Used her garters for insulation
Braked downhill until the wooden brake blocks wore out, inspiring the invention of leather brake linings
By the time she reached Pforzheim, she had proven the impossible: the automobile was practical, reliable, and ready for the world.
Her journey changed everything, customers started arriving, newspapers began reporting, investors took notice.
The invention had its champion. Now it needed protection.
3. From Workshop to Patent Office: The Birth of the Motorwagen Patent
Long before the Motorwagen had proven itself, Benz made a strategic decision that separated him from many inventors of his time. He didn’t wait for perfection. He didn’t wait for approval. He didn’t wait for the market.
He filed a patent.
On 29 January 1886, Karl Benz submitted his application to the German Patent Office for:
DRP 37435 - “Vehicle powered by a gas engine”.
It was granted later that year, giving Benz exclusive rights to:
The fundamental architecture of a self-propelled vehicle
The integration of an internal combustion engine into a lightweight chassis
The three-wheel mechanical configuration
The specific engineering arrangement that made the vehicle operable
This single document did more than protect an invention. It defined the world’s first automobile in legal and historical terms.
In the eyes of the law, of industry, and of history, the automobile officially existed.
It also gave Benz enormous strategic leverage, the kind modern innovators often overlook.
4. Turning Patent into Business: How Benz Built the First Auto Company
With the patent in hand and public excitement growing, Benz established Benz & Cie., which quickly became the world’s leading automobile manufacturer in the early 1900s.
A patent alone doesn’t build a business, but it builds the foundation of one.
Here’s how Benz used his IP strategically:
1. Exclusivity in Early Market
With virtually no competition and with patent protection, Benz could sell his Motorwagen without fear of immediate imitation. He was protected during the years when he needed it most, the early, vulnerable phase.
2. Licensing to Expand Globally
Rather than manufacturing everywhere, Benz licensed production. A French businessman, Emile Roger, began building and selling Benz cars in France, accelerating global adoption.
Licensing allowed expansion without overwhelming manufacturing capabilities, still a powerful strategy for today’s inventors.
3. Building a Brand
Patent protection gave Benz credibility. Being “the first patented automobile” became a marketing message, one that still echoes through the Mercedes-Benz brand today.
4. Reinforcing with Additional Patents
Benz didn’t rely on just one patent. As the vehicle evolved, so did the intellectual property around it. Each improvement, steering, chassis stability, engine design, became a protective layer, forming what we now call a patent portfolio.
In other words:
One bold idea.
One strategic patent.
A lifetime of innovation built on top of it.
5. Building Protection: The Automobile Patent Portfolio
While DRP 37435 is the most famous, Karl Benz filed several other important patents that shaped automobile evolution.
The Steering Revolution (1893)
One major flaw of early three-wheelers was stability. Benz invented and patented the double-pivot steering system, which made four-wheel vehicles controllable and safe. This system became fundamental to modern car steering.
Engine & Mechanical Improvements
Benz patented multiple enhancements to:
Carburetion
Gear transmission
Vehicle frame stability
Brake adjustments
Each patent expanded his legal protection and commercial advantage.
The Patent Lifecycle Strategy
Benz intuitively followed what modern IP consultants now call a layered protection strategy:
Foundational patent → protects core invention
Improvement patents → protect incremental innovations
Business model patents → enable licensing, partnerships
This strategy made it extremely difficult for competitors to replicate the Motorwagen without infringing something.
It’s the same strategy that successful startups and tech companies use today.
6. Why Karl Benz Still Matters: IP Strategy Lessons for Today’s Innovators
Most people know Karl Benz as the father of the automobile. Very few understand that his success wasn’t just engineering brilliance, it was intellectual property strategy done right.
Here are the lessons every inventor, startup founder, and business owner can take from Benz’s journey:
Lesson 1: File Early - Even If the Product Isn’t Perfect
Benz filed his patent before the Motorwagen was polished or market-ready.
This secured:
Priority date
Legal recognition
Competitive advantage
If you’re developing something new, filing early protects you even while you refine your invention.
Lesson 2: A Patent Isn’t Just Protection - It’s a Business Tool
Benz used his patent to:
Attract investors
Build his brand
License production
Expand globally
Modern patents do the same: they communicate credibility, innovation, and seriousness.
Lesson 3: Build a Portfolio, Not Just a Single Filing
One patent gives you a start.
A portfolio gives you a fortress.
Benz systematically patented improvements, creating layers of protection. Today’s innovators should do likewise: protect enhancements, variations, and secondary features.
Lesson 4: Your Invention Needs a Story
Bertha Benz’s 1888 journey transformed a technical machine into a human narrative.
Your invention, too, needs a story. One that resonates with users, investors, and partners. IP protects your idea, but storytelling sells it.
Lesson 5: Innovation + Protection = Market Leadership
History is clear:
Benz didn’t win because he built the first car.
He won because he protected it, commercialised it, and innovated continuously.
That combination: invention + IP + business; remains the formula for success today.
7. Beyond History: What This Means for You
Most modern inventors or businesses don’t realise that they’re in the same position Karl Benz was in 1886:
You have an idea.
You have a product (or you're developing one).
You have challenges, uncertainty, and competitors.
And you need a roadmap that protects your innovation while enabling business growth.
That’s exactly what intellectual property provides.
Whether you’re creating a machine, a software product, a brand, or a new design, the principles remain the same:
Protect early.
Protect strategically.
Think business, not just invention.
Build a portfolio, not just a single filing.
Tell your story.
The world today may be faster and more crowded than in Benz’s time, but the fundamentals of innovation haven’t changed, and the value of a strong IP foundation is greater than ever.
Final Thoughts
Karl Benz didn’t just invent the automobile.
He invented a new way of thinking, a world where individuals could create transformative technology and use intellectual property to bring it to life.
That first patent didn’t just protect a machine.
It propelled an industry, shaped the future of mobility, and proved that one well-protected idea can move the world forward.
If you’re working on something new, whether a product, brand, or technology, remember:
Your own “DRP 37435 moment” might be closer than you think.
And like Karl Benz, the right IP strategy can turn your invention into a legacy.
